1. ISSUE
1.1 Stage 2 of the Papaioea Place Housing Redevelopment is funded through Programme 1219 – Social Housing – Papaioea Stage 2.
1.2 The Finance and Performance Committee Chairperson requested a quarterly update to be brought back to the Finance and Performance meeting for the duration of the construction period.
1.3 The terms of reference for the new Infrastructure Committee Meeting include scope for updates on the progress of the Papaioea Place Redevelopment. As such, this report is being presented to this Committee, and all future update reports for this programme will now be presented to the Infrastructure Committee as opposed to the Finance and Performance (now Finance and Audit) Committee.
1.4 In the December 2019 Infrastructure Committee Meeting it was agreed that the quarterly updates would change to 6-monthly updates moving forward.
2. BACKGROUND
2.1 The Papaioea Place project form of contract is a design and build contract between Palmerston North City Council (Principal) and Latitude Homes (Contractor) of New Plymouth.
2.2 Papaioea Place Stage 1 was delivered through Programme 357. This saw the demolition of the 32 existing units and the construction of 50 new units in their place. Stage 1 was completed as planned on 28 February 2020 and within budget.
2.3 Papaioea Place Stage 2 sees the demolition of the remaining blocks of units on site and the old hall and the construction of an additional 28 new units. Once complete this will take the total number of new units on the site to 78.
2.4 The overall project management for both stages of the development is being provided by WT Partnership Advisory. The day-to-day project management is being carried out by Council Officers.
2.5 Site meetings and Project Control Group meetings are held on the last Thursday of each month. This report is a summary from the virtual meeting on 4 May 2020.

PALMERSTON NORTH CITY COUNCIL
TO: Infrastructure Committee
MEETING DATE: 3 June 2020
TITLE: Six Month Transport Network Safety Update Report - 2019-1
Presented By: Robert van Bentum, Manager - Transport and Infrastructure
APPROVED BY: Tom Williams, Chief Infrastructure Officer
1. BAckground
1.1. Council is committed to improving safety for all road users, including vulnerable users such as pedestrians and cyclists through reducing all crashes but with a specific focus on reducing deaths and serious injury crashes. In line with the government’s policy statement (GPS) Council invests in a variety of measures across the network to improve safety.
1.2. Council has previously requested quarterly updates on specific elements of network safety focussed on users such as pedestrian, school bus users and cyclists or on specific elements of the network such as intersections. While such reporting may provide a snap-shot of the situation for specific user groups or locations, because of the integrated nature of the transport network, many interventions impact on multiple groups and safety outcomes.
1.3. To provide a more holistic view of safety across the network Officers have sought to develop a report which provides a safety overview of the network. Because changes in safety trends are slow to change given the small data sets and the impact of safety interventions is equally slow to emerge, it is proposed that the Network Safety Update is provided on a six monthly interval.
1.4. The scope of the update report has been developed to provide a brief overview of the safety issues, analysis of the problem and identification of possible solutions as well as an update on the actions proposed and progress towards implementation. The report is therefore divided into three areas:
· The safety problem
· Safety issues and causes
· Key approaches to improving safety
· Recent safety improvements
· Transport network safety action plan
2. The Safety Problem
2.1.1. Identifying safety issues within a transport network can be achieved through:
· Analysis of crash data
· Undertaking audits of the network and any significant project intervention
2.1.2. The primary source of information on the safety of a network is the data collected on crashes in the network. NZTA maintain a database called Crash Analysis System (CAS) which is used to capture and analyse crash incidents. The database distinguishes between deaths, serious injuries and minor injury crashes which have been reported to the police and involve pedestrians, cyclists and/or vehicles in any combination.
2.1.3. While the CAS database is critical and relied on heavily by NZTA when prioritising and ranking projects for funding there are problems with relying on CAS to determine the extent of the safety problem such as:
· under-reporting of minor or non-injury crashes due to their not being reported – e.g. cyclist and vehicle
· inaccurate identification of the cause of the accident leading to incorrect conclusions around the need and design of any safety mitigation e.g. when a medical event has occurred causing a driver to leave the road
· the perception of poor safety can be a key determinant of behaviour even where there are few recorded crash incidents e.g. use of on-road cycle ways
· crash data cannot help to predict where safety issues may emerge in a network as traffic volumes change or when other improvements of changes are made to a network
2.1.4. For the reasons outlined, safety problems are also identified by undertaking safety audits of specific aspects of the network in general and by undertaking safety audit of all new projects and network modifications. These audits identify specific safety mitigation measures which apart of re-design of the project may include signage, barriers, line-marking or other safety related treatment.
2.2. Network Wide Crash Data
2.2.1. At a national level New Zealand has struggled in recent years with reducing the deaths and serious injury crashes on its road network. In the last few years the road toll has been rising despite significant investment by central government in safety intervention. There are likely to be many reasons for this including:
· increasing traffic volumes
· driver skill levels
· driver behaviour
2.2.2. Council has adopted two KPI’s to monitor network safety performance with the target being an on-going reduction in each. As with the national situation, achieving on-going reductions in crashes relies on addressing a range of factors, many of which are outside of the control of Council as network manager. However by analysing the reasons for crashes and risks in the network Council is able to identify some elements within its control which it can change and modify.
2.2.3. The two KPIs tracked are listed below and Figures 1 and 2 below summarise crash data for the last and previous periods. These are:
· annual average deaths and serious injury crashes
· five year annual average deaths and serious injury crashes
Figure 1: Annual Fatal and Serious Injury Crashes for periods ending Q3.
Figure 2: Five Year Annual Period of Fatal and Serious Injury Crashes for periods ending Q3.
2.2.4. In the 12 month period between 1 April 2019 and 31 March 2020, there were 664 crashes recorded in Palmerston North. This comprised of 3 fatal and 41 serious injury crashes. This is an overall decrease of 102 crashes on the previous 12 month period. While the number of total reported crashes are down, the total number of serious injuries have increased significantly.
2.2.5. It should be noted that Q2 and Q3 of the 19/20 FY is unusually lower than previous quarters and could be attributed to NZTA crash data not being updated at the time of analysis. As such there may be additional crashes unaccounted for.
2.2.6. In comparison to previous years, the annual number of Deaths and Serious Injury Crashes have been trending upward and the period ending 31 March 2020 was the highest in the last 10 years. The 5 year period also confirms the upward trending of fatal and serious injury crashes.
2.3. Network and Project Safety Audits
2.3.1. To help inform safety planning and investment across the network Officers have completed and commissioned safety audits of specific elements of the network. While this work is on-going, deficiencies identified through these safety audits are included in minor safety programmes of work.
2.3.2. Safety audits which have been identified as being required include:
· Roundabouts
· Traffic signals
· Pedestrian and pram crossings
3. Safety Issues and Causes
3.1. Network Wide Safety Issues
3.1.1. PNCC has been working with NZTA to use crash data in combination with an understanding of the network to identify priorities for investment. The work has been focussed on developing a Network Operating Plan (NOP) and Network Operating Framework (NOF). The process makes use of a network model to combine priorities for different modes of transport on different corridors to identify priority areas for improvement.
3.1.2. A heat map showing the distribution and intensity of priority safety treatment areas within the network is included as Figure 3 below.
Figure 3: Heat Maps of Serious and Fatal Injuries 2015-2019
3.1.3. Many of the problem areas are intersections. The NOP / NOF analysis has identified some key issues in the network including:
· high traffic speeds on many of the older roundabouts on the collector road network e.g. Church / Cook, resulting in poor safety outcomes for cyclists and pedestrians as well as more vehicle crashes
· issues with mid-block crossings on the dual carriageway network, where vehicles on side streets are trying to cross four or more lanes of traffic. Impatience and poor judgement are resulting in a higher level of crashes at these junctions
· issues with high speeds on some local roads used as alternative routes during busy network periods
3.2. Fatal Crashes in the Last 12 Months
3.2.1. There were 3 fatal crashes which occurred in Palmerston North in the last 12 months and the contributing factors are outlined as follows:
· A fatality occurred on the Pioneer Highway Shared Path in September 2019, where a motorbike crashed into a cyclist. Preventing motorbikes access on shared paths, through the use of restrictive measures (e.g. Bollards, gates etc) would be expensive to roll out and prohibitive to cyclists. Instead to improve compliance, prohibitive motorbike signage on shared path entrances is planned for installation.
· One fatality occurred on Cardiff Street, Awapuni in March 2020, where the driver collided with a tree who is suspected to have died by a heart attack. Currently Cardiff Street is being considered for traffic calming treatments in Council’s Road Safety Programme.
· On SH3 Napier Road a fatality occurred in March 2020, near Stoney Creek Road where the driver was travelling at excessive speed (180km/h). The driver crossed the centreline and collided with a truck. As this is a State Highway, NZTA is the responsible authority to consider any required road safety improvements on this road.
3.2.2. In general, the cause of crashes can vary wildly and can often be influenced by factors unrelated to network design and condition, such as driver behaviour and vehicle condition/design.
3.3. Pedestrian Crashes
3.3.1. Figure 4 below shows the trend of pedestrian crashes occurring over the last several years.
Figure 4: Pedestrian crashes for 12 month period ending Q3.
3.3.2. There have been 33 pedestrian crashes in the last 12 months, which include no fatal and 11 serious injury crash. The number of serious crashes occurring is much higher in comparison to previous years.
3.3.3. In general pedestrian crashes are distributed across the network however higher concentrations of pedestrian crashes do occur within the CBD where there is high pedestrian activity. In particular Square East has had five minor injury and one serious crash involving a pedestrian in the last five years.
3.3.4. A common barrier to walking is the ability for pedestrians to cross the road. In many locations, there are perceived safety concerns due to high speed, high volume or multilane roads, which either have no or poor crossing facilities. While locations considered unsafe may not have pedestrian related crashes at the location, they are still deterrents to getting the community walking.
3.3.5. Another significant contribution to pedestrian injuries is trip and fall events associated with poor condition footpaths and crossings. Surveys of the footpath network identified approximately 2100 serious footpath faults (grade 4 and 5). Approximately 20% of the serious footpath condition issues are associated with damage from the roots of street trees. Many of the serious footpath faults have been identified within the city.
3.4. Cycle Safety Issues
3.4.1. There have been 36 cycling crashes occur in the last 12 months, which include 1 fatal and 5 serious injury crash. While this is an overall decrease of 3 crashes compared to the previous period, it is an increase of 1 fatal and 2 serious crashes involving cyclists.
3.4.2. Figure 5 below shows the trend of crashes occurring over the last several years.
Figure 5: Cycling crashes for 12 month period ending Q3.
3.4.3. A common problem with cycling safety is at intersections. In particular roundabouts in Palmerston North have a poor record of crashes due to improper design, high operating speeds and high traffic volumes. Examples include the intersection of Cook/Church, Cook/ College and Ferguson/Victoria. The inconsistent approach to designing these roundabouts have led to confusion on how cyclists should navigate these.
4. Key Approaches to Improving Safety
4.1. NZTA Safe Networks Programme (SNP)
4.1.1. The Governments Road to Zero initiative looks to improve road safety by reducing the number of deaths and serious injuries occurring on roads in New Zealand. To achieve this goal, the NZTA have developed the Safe Networks Programme (SNP) which looks at providing significant funding towards road safety projects over the next 10 years within a separate funding stream.
4.1.2. The SNP have developed a tool which has assessed intersections and corridors around the country where it has identified potential projects that could be eligible for subsidised funding. The approach provides a streamlined process where treatment solutions are pre-approved up to a maximum value simplifying the process of securing funding approval from NZTA.
4.1.3. During the lockdown, Council Officers met (virtually) with the SNP team and assessed all potentially eligible locations within Palmerston North. The group review 64 intersections and Corridors for possible treatment, where 53 were submitted to be considered for subsidised funding.
4.1.4. NZTA have indicated that most of the co-funding for local authority safety focussed roading programmes will be provided through this separate funding allocation. As part of this approach the Local Road Improvement funding allocation will be reduced. There is also an indication that safety programmes may attract higher levels of subsidy that the current standard FAR rate.
4.2. Minor Safety Improvements
4.2.1. Council Officers receive many requests to improve road safety around the network. This includes but not limited to solutions to address crashes, speeding, pedestrian and cycle safety. To improve safety and address these concerns on our local roads, minor infrastructure is generally required. However due to the overwhelming number of requests, the available funding is insufficient to satisfy demand such that a robust prioritised process is needed to ensure the optimum safety outcome is achieved with the limited available funding.
4.2.2. Generally local road safety projects have been delivered through the Minor Safety Improvements Programme. In the past the determination and selection of projects has been rather subjective and unduly influenced by external advocacy rather than safety merit and evidence. This has led to lower value projects being prioritised ahead of others with greater merit.
4.2.3. To address this, Council Officers are developing a Road Safety Prioritisation Tool to assess projects which can deliver the greatest road safety improvement relative to the level of expenditure. To do this, the tool will categorise and evaluate requests based on traffic data/evidence, strategic alignments as well as consider surrounding land use. Projects considered to achieve the highest score in terms of safety value for money spent would be prioritised and planned for delivery through the Minor Safety Improvements Programme.
4.2.4. The prioritisation tool will look to prioritise project selection in several categories, to enable early identification and timely delivery of the programme of work. The categories adopted at this stage include:
· Local Area Traffic Management Treatments
· Pedestrian Improvements
· Cycle Improvements
· Public Transport Improvements
4.2.5. Local Area Traffic Management Treatments will look to address speeding and short cutting through our local roads. They will generally be prioritised in residential areas as part of greenway corridors aligning with the Urban Cycle Network Master Plan or where they are close to schools and there is a strong likelihood of children walking to school.
4.2.6. Pedestrian improvements will look to deliver projects to assist pedestrians to cross roads at high pedestrian demand locations. Areas around Local shopping centres, parks and school will generally be prioritised where higher pedestrian foot traffic is occurring. Investment in renewal of footpaths to address the backlog of faults will continue to be a key focus with spending of at least $1m programmed to occur in each of the 2019/20 and 2020/21 financial years.
4.2.7. Cycle Improvements will look to address locations of pinch points, which poses a specific safety issue to cycling. This work will focus on existing on-road cycling routes which are not part of the Urban Cycle Network Implementation Plan.
4.2.8. Public Transport Improvements will look to address safety issues associated with the delivery of public transport services, bus stop locations and approaches and key intersections or corridors for bus services.
4.3. Urban Cycle Network Implementation
4.3.1. The key initiative for cycle safety is the implementation of the Urban Cycle Network Master Plan looks to deliver on a connected and integrated cycling network within Palmerston North. This will be achieved by developing key cycle corridors which will safely allow cyclists to get around the city, as well as addressing key intersection deficiencies. The programme will bring together a range of individual cycling projects into a coordinated programme of work.
4.3.2. The programme business case is currently being finalised prior to final submission to NZTA for funding. It is hoped that NZTA will approve funding for the 2020/21 financial year as well as provisionally approving funding into the next RLTP.
4.3.3. Construction work is underway on the first of the routes along College Street with planning and design well advanced for other key routes along Featherston, Summerhill Drive, Albert and Victoria Streets.
5. Recent safety improvements
5.1. Road Safety Improvements
5.1.1. The intersection of Walding Street / Taonui Street was modified in October 2019, due to the high number of crashes occurring at this intersection for over a decade. To improve safety, changes were made to the traffic islands where vehicles on Taonui Street were only permitted to turn left (i.e. they could not go straight through or turn right).
5.1.2. In November 2019, Coventry Street had two splitter islands and two slow points installed along its length. This road was selected for treatment due to the high operating speed (52km/h) and large number of crashes (10) over the past five years.
5.1.3. Detailed design has been completed and final procurement is awaiting resolution of a land acquisition issue, prior to constructing a roundabout at the intersection of Monrad Street and Ronberg and Pencarrow. In 2019, speed indicator devices and traffic islands were installed at this intersection as interim treatments ahead of the roundabout construction. The speed indicator devices were installed both to advise drivers of their speed and encourage them to slow down, while the traffic islands were designed to reduce the speed of approaching and turning vehicles by increasing the visibility of the intersection.
5.2. Pedestrian Improvements and Initiatives
5.2.1. In February 2020, Officers altered the traffic signal phases on church street outside the plaza to include an additional pedestrian crossing phase. The change was to improve pedestrian priority in the CBD which is anticipated to improve pedestrian movements and safety whilst discouraging unnecessary traffic through the square.
5.2.2. Other pedestrian improvements in the CBD are being advanced as part of the Streets for People Square East upgrade.
5.2.3. Furthermore, the upcoming Stage 2 of the speed limit bylaw will look to reduce the speed limit of the road within the CBD 2 of the speed limit bylaw review where a lower CBD speed limit will be explored.
5.2.4. Council has continued its significant investment ($1m) in footpath renewals with the programme on track to remedy over 700 of the 2100 serious faults identified across the footpath network by the end of the 2019/20 financial year. Engagement of a panel of six contracting companies has enabled the full programme budget to be spent despite the impact of Covid-19. Addressing the backlog of footpath condition faults will require on-going renewal investment at this level for at least 3 further years, given that new faults continue to emerge and develop.
5.3. Cycling Improvements and Initiatives
5.3.1. The first stage of the College Street cycleway from Fitzherbert Ave to Victoria Ave has been completed following resealing and line marking. Work is also about to begin on the indented parking on College Street in the vicinity of the Awapuni neighbourhood centre.
5.3.2. Officers are still working with Schools to deliver the Bikes in Schools programme. This programme looks to setup schools with bikes, bike storage and tracks to enable children to development their cycle skills education. At present, there are 10 schools under the Bikes in Schools Programme, with work well advanced with Awapuni School for 2019/20 and the selection of the next school for 2020/21 underway.
6. Transport Network Safety action plan
6.1. The key elements of Council’s investment in delivering long term improvements in road safety can be grouped into the following four areas of work:

PALMERSTON NORTH CITY COUNCIL
TO: Infrastructure Committee
MEETING DATE: 3 June 2020
TITLE: Update Memorandum: 3 Waters Asset Condition
Presented By: Jono Ferguson-Pye, Assets and Planning Manager
APPROVED BY: Tom Williams, Chief Infrastructure Officer
RECOMMENDATION(S) TO Infrastructure Committee 1. That the memorandum titled “Update Memorandum: 3 Waters Assets Condition” and reported on 3 June 2020, be received.
|
1. ISSUE
1.1 Considering recent failures of critical water and wastewater systems in several Councils (e.g. Wellington Water) Council has requested an update on the condition of the city’s 3 waters services (wastewater, water supply and stormwater) assets.
1.2 Wellington City Council have established a taskforce to examine why unexpected water asset failures have occurred and to develop an action plan with firm recommendations. The issues the taskforce is examining are as follows:
· The condition of Wellington’s water infrastructure
· The adequacy of the current renewals and maintenance programmes
· Requirements, including investment, to deliver a sustainable long-term water network
1.3 The purpose of this report is to summarise the known condition of Palmerston North City’s 3 Waters assets and discuss the asset management issues that need to be addressed to ensure the sustainable delivery of 3 water services.
2. overview of 3 waters assets
2.1 Wastewater: the wastewater system comprises the following key asset components:
· 418 km of pipeline, 5,679 manholes and 27,800 lateral connections serving Ashhurst, Aokautere, Longburn, Linton, Bunnythorpe and the city.
· 35 pumping stations
· A Tertiary treatment facility at Totara Road with primary treatment and buffer storage via two oxidation ponds at Ashhurst
2.2 Water Activity: the water system services the city, Ashhurst, Bunnythorpe, Longburn and Linton. The system comprises the following key asset components:
· 548 km of water mains, 4,650 valves. 3,128 hydrants, and 28,162 tobies
· 362 swab launchers, 196 service connections, 2095 water meters, and 405 back flow preventers
· A treatment plant and two dams at Turitea, 21 bores and pump stations, and 14 reservoirs
2.3 Stormwater: the stormwater system is made up of a:
Primary System: being a reticulated stormwater system of pipes, pump stations, open drains and streams including stop banks.
Secondary System: being a system of open swales, road, kerb and channel, detention storage areas as well as informal overland drainage pathways.
The primary and secondary systems comprise of the following key asset components:
· 218 km of pipelines and culverts, 113 km of sump, kerb and mains connection, 5,271 manholes, and 90 flood gate structures.
· 428 inlet / outlet structures, 14 km of stop banks, 15 pump stations, 24 storage and treatment basins, and 7.6 hectares of drainage reserve.
3. Waters asset condition and performance Understanding
Summary of Waste
Water Asset Condition:
3.1 Collection network: the overall condition of the collection network is in good physical condition with pipe deterioration having minimal impact on performance. The bulk of the pipes are in the young to middle part of their asset lifecycle.
3.2 Isolated failures in trunk network: while the average age of the network has significant residual life, there have been several isolated failures in key parts of the network indicating a need for more detailed and complete condition assessment. There has been no inspection of large diameter trunk mains. Past trunk main failure suggests additional investment in trunk main inspections and condition assessment is required.
3.3 Wastewater Treatment Plant (WWTP): the WWTP will need to meet the demands of the activity until the BPO is completed. The ageing plant is likely to need approximately $4.5m of expenditure in renewal and upgrading of key treatment components to ensure the plant operates reliably until the BPO is finalised and constructed.
3.4 Single point of failure vulnerability: all the city’s wastewater is treated through the WWTP. The critical nature of reliable plant performance has been highlighted by failures of some key items of mechanical plant and equipment.
3.5 Water pump stations: most pump station assets are in sound condition. However, the electrical and mechanical components are needing to be replaced due to age and obsolescence. Condition assessments have identified a significant backlog of renewals to replace components which are coming to the end of their life. There is a need to upgrade pump stations to provide higher levels of reliability, operational visibility and standardisation to reduce operational risk and the on-going cost of maintenance.
3.6 Wet weather inflow: there is an increasing frequency and volume of wet weather overflows due to significant stormwater inflow and infiltration to the wastewater network. The condition of the network is such that with an increasing incidence of high intensity rainfall events more frequent and larger volumes of wet weather overflows can be expected.
3.7 Wet weather network capacity constraints: the need for pro-active renewal and upgrade of the critical network assets including large capacity sewer mains, sewer rising mains and wastewater pump stations is highlighted by the increasing incidence of wet weather overflows and surcharging. Council is pursuing several strategies such as implementing pressure sewers, increasing wet weather storage, and looking to identify and address stormwater inflow at source under a dedicated I&I programme.
3.8 In addition to looking to address private property stormwater inflows, Council will also invest in targeted renewal of the sewer network in the catchments with the most severe stormwater infiltration and inflow. Even with this investment the expectations around any reductions in wet weather flows are low, with the primary goal being to limit the extent to which flows will increase over time.
3.9 Renewal planning: the current approach to renewal planning for the wastewater activity cannot provide the necessary certainty around renewal funding requirements nor the assurance that renewals have been optimised. This is an issue that needs to be addressed through improved asset management practice and through programmes in the upcoming Long Term Plan.
Summary of Water Supply Asset Condition:
3.10 Water supply network: the water supply network and source capacity are sufficient to meet current and foreseeable future demand.
3.11 Water supply pipelines: most water supply pipelines are in good physical condition and exhibit no sign of structural failure. Specific condition issues for pipelines are noted in the following areas:
· Cast iron pipelines have been progressively replaced. However, remaining cast iron pipes are still contributing to discoloured water incidents but have become less of an issue as a large proportion have been replaced.
· There is significant Asbestos Cement (AC) pipework, which is coming to the end of its life. The current rate of renewals indicates 10-15 years to complete replacement of all AC pipes. There is currently a back log in renewals. The random nature of AC pipe failure is creating challenges in planning renewal priorities.
· The condition of the Ashhurst rising main was identified as a significant risk to the system. The rising main is currently being renewed with stages 1 and 2 of the 3 stage renewal project due to be completed in late 2020. The final section is scheduled for renewal in 2021/22.
3.12 Bores and Water Compliance: bores exhibit steady yield decline with assessed useful life between 15 and 30 years. Apart from the Railway Road bore there is currently no storage at any of the city bore sites meaning recommended minimum residual chlorine levels are not achieved in much of the network. Bore installations will need to be upgraded to include storage and treatment facilities to enable water quality to be improved to comply with legislative requirements. Additional bores will also be required to address resilience issues and respond to growth demands.
3.13 Turitea Dam: the seismic performance of the Upper Turitea Dam is assessed to be good. A detailed seismic assessment has confirmed a low risk of failure for the Safety Evaluation Earthquake. While there is residual uncertainty in respect of the upper dam’s performance, the focus has shifted to how best to mitigate impacts on at risk properties and public downstream of the dam in the event of a failure.
3.14 Water Treatment Plant: the 2017 AMP recorded an overall condition score of excellent for treatment facilities and a multi-year seismic programme is in place and funded for the treatment plant. A placeholder programme is currently being investigated in preparation for future Drinking Water Standards New Zealand requirements.
3.15 Turitea catchment yield: there are no immediate supply issues but long-term the sustainable yield from the Turitea catchment will decline. This will lead to an increased reliance on bore supplies with a corresponding need to build additional redundancy and resilience across the city’s bores, requiring additional capital new investment. Renewal expenditure in the bore stations must also increase to ensure current water quality, safety and levels of service are maintained.
3.16 Network issues: condition information indicates that the valves, tobies and backflow devices in the water supply network are in poor condition and present a significant contamination, security and reliability risk. The poor condition of these assets has resulted in a 100% increase in the annual expenditure on reactive maintenance and replacement. Significant targeted renewals investment is urgently required. A dedicated programme for renewal of tobies, manifolds and back flow prevention is recommended. At the current rate of renewals investment replacement of the 9000 tobies, which have no manifold or backflow, will take 25 to 30 years.
Summary of Stormwater Asset Condition:
3.17 General condition: the 2017 AMP noted that most of the stormwater network is in good to very good condition. However, inspection and condition data for a representative cross-section of the network is required to confirm this. It is noted that specific condition survey data for stormwater reticulation is limited. The condition grading is largely based on assumed rates of deterioration for well-constructed pipes under average conditions.
3.18 Capacity and performance: of the primary network varies widely, resulting in more frequent ponding and operation of the secondary system. Higher intensity rainfall events, increased infill and associated increases in the percentage of impervious surfaces are impacting the performance of some parts of the network. This is resulting in increased reliance on secondary drainage pathways.
3.19 Targeted upgrades of network: monitoring and investigation of specific localised ponding and flooding issues has highlighted a range of capacity issues within the existing network. A city-wide flood mitigation programme will be put forward for consideration for the Long Term Plan. This programme will be focused on large scale flood mitigation projects aimed to alleviate flooding within the city. The proposed programme will include the following:
· Large detention and or attenuation ponds for the larger developments proposed in urban growth Structure Plans
· Re-aligning or diverting various large open channels from high risk flood areas to the outer boundary of the city
· Renewal of large (above 900mm diameter) stormwater pipes within the city network potentially at risk of exceeding its design life or upgraded to accommodate the increasing demand of stormwater capacity
3.20 Pipe work: the 2017 AMP noted less attention has been given to the pipe network on the assumption that given most of the network is less than 50 years old there will be few condition or maintenance issues. This assumption needs to be tested through thorough condition assessment across the network.
3.21 Older network components: there is evidence of problems with the performance of the network in older parts of the city or where services are located in private land. There is also uncertainty about the condition and performance of the large diameter buried pipes (>1200mm) and box culverts.
3.22 Stormwater pump stations: the 2017 AMP noted that pump stations are in good condition, but detailed condition surveys particularly of the mechanical and electrical components are required to develop accurate renewal priorities. Further work carried out post 2017 indicates that many pump stations are not fit for purpose and poorly designed. Additional capital investment is required to upgrade many pump stations to provide for stand-by pumps, larger chambers and better electrical control to enable pumping rate to match incoming flow rates. A renewals programme informed by good condition data is needed in this area.
4. Asset Management Maturity Assessment
4.1 In July 2019 the Asset Planning Division (APD) commissioned an independent Asset Management Maturity Assessment. The assessment is based on Treasury’s model and aligns with the International Infrastructure Management Manual (IIMM).
4.2 The purpose of the assessment was to evaluate the Council’s level of asset management practice across the organisation and highlight where the APD needs to target its work programme heading into the Long Term Plan and beyond. The following is a brief summary of the assessment findings for the asset management of the 3 Waters assets:
Understanding of asset condition:
“The single biggest issue for the Three Waters is a lack of understanding of the condition and capacity of the pipe networks. Until recently the asset networks were mainly run to failure. There has been little warning of failures nor understanding of the implications. There has been proactive replacement of water and wastewater assets, but the incidence of failures/unplanned replacement was still high. More condition inspections have been programmed which are expected to improve the knowledge of the network and target interventions to prevent asset failure.”
Asset register data: overall asset data is reasonably complete across the 3 Waters activities, but there are gaps in the available condition information.
Asset performance condition: part of the assessment evaluation examined how the Council measures and manages the performance of its assets. The assessment noted that there are significant gaps in the 3 Waters network of assets particularly in terms of condition and performance data.
4.3 Key Learnings: the asset management maturity assessment emphasised the lack of understanding of the condition and capacity of pipe networks across the 3 Waters assets. The approach to investment in renewals needs to be informed by a strategic renewals plan directing the approach taken with each activity. However, an effective and efficient approach to renewals over the long-term cannot be achieved without robust processes and systems in place to ensure thorough asset condition information is gathered.
5. asset management improvement
5.1 The maturity assessment noted the unexpected incidence of asset failures and unplanned replacement across the 3 Waters assets. The assessment has identified the on-going need for investment in a continuous process of asset condition assessment to inform optimised renewal planning and investment in the future.
5.2 It is acknowledged that the current approach to renewal planning for the 3 Waters assets cannot provide the necessary certainty around renewal funding requirements nor the assurance that renewals have been optimised. A better understanding of the condition and capacity of the 3 Waters networks will enable evidence based renewals decision-making and result in the long-term sustainable management of 3 Waters’ assets. The strategy for improvement is based around two key elements namely:
· Implement a greater organisational focus on asset management planning through the Assets and Planning Division.
· Investment in enhanced condition assessment and performance modelling to inform optimised renewal planning and the delivery of a sustainably managed water network.
5.3 Asset Management Improvement Actions: The Asset Management Maturity Assessment has provided a comprehensive suite of prioritised recommendations. These recommendations will be incorporated into the improvement actions developed for the:
· Strategic Asset Management Plan
· 3 Waters activity AMP Improvement Plans
· Reflected in the programme of works being developed to support the Long Term Plan
· Reflected in the APD’s ongoing work programme to improve the level of asset management practice across the organisation and drive the delivery of the actions set out in the activity Asset Management Improvement Plans
