1 Introduction The purpose of this Activity Management Plan (AMP) is to outline the significant issues associated with the Council’s assets and to show how the Council proposes to manage the schemes in the future. This plan summarises the various components of the West Eyreton water supply scheme, its condition and performance, and identifies future funding requirements including upgrades where necessary. Further details of the asset management practices used by Council to responsibly manage this scheme are summarised in the District Water Supply AMP. Projects identified to improve asset management processes for this scheme will also benefit the performance of other 3 waters schemes and are managed at a District level for efficiency.
2 Scheme Description (What Do We Have?) The West Eyreton Water Supply Scheme is a rural restricted (4000 litres/connection/day) water supply with the exception of the school and community hall. The water is sourced from the secure groundwater well, approximately 100 metres deep which feeds both the West Eyreton and Summerhill schemes. The water is chlorinated to provide a residual disinfection to protect against contamination in the private on-site tanks. The source water complies with both the bacteriological and protozoan contamination requirements in the Drinking Water Standards. A back-up supply is available in the form of the old shallow well, which was redeveloped in 2011. Some key statistics (2013/14 year) of the scheme are shown in Table 1. The extent of the currently serviced area and full flow data records are presented in Figure 15. A schematic view of the principal source, treatment, and distribution system is presented on the following page Figure 1.

3 Scheme Management Issues (What Do We Need to Consider?) There are a number of key aspects to consider when managing a water supply; these include: • Desired & actual Levels of Service • Asset condition & Criticality • Capacity & performance of the supply • Risks associated with the supply • Growth predictions for the scheme These issues have been assessed in detail and are summarised in the following sections.
3.1 Levels Of Service Table 3 below sets out the performance measures and targets for the West Eyreton water supply scheme, and records achievement for 2011, 2008 and 2004.

Figure 2 and Figure 3 below illustrate the remaining useful life profiles based on component age and asset design life. Figure 3 also includes the location of any actual bursts recorded on the network since 2007. The Council continues to work on an improvement project collecting condition and maintenance data to support the remaining useful life profiles and provide a truer picture of asset condition. Figure 2: Remaining Useful Life Profile by Replacement Value
3.3 Asset Criticality Asset criticality provides an indication of the importance of an individual asset and the corresponding impact on the service delivery should the asset fail for any reason. Criticality is used in risk based investment decisions to help decide when an asset should be replaced to avoid the consequences of failure. The Council has developed an assessment process which scores assets from most critical ‘AA’ to least critical ‘C’. The pipe criticality scoring process has been significantly improved through automation and dynamic links to GIS data layers for this AMP. A similar process is planned for all facilities assets as part of the 2015 AMP Improvement Programme. Figure 4 provides a spatial view of asset criticality for the scheme.

Trim: 151021144448 Page | 13 3.4 Risk Assessment A risk assessment has been undertaken for the West Eyreton Water Supply Scheme. The key output from the risk assessment is the identification of any extreme and high risks to the scheme, which need to be mitigated. The preferred mitigation method can then be included in the forward works programme. A total of 58 possible events were considered in 2014. Table 5 below shows a summary of the number of events at each level of risk for the West Eyreton water supply scheme. Table 5: Number of Events per Level of Risk
Risk Level 2004 2008 2011 2014

There are no high or extreme risks on this scheme.
Trim: 151021144448 Page | 14 3.5 Disaster Resilience Assessment The 2009 Disaster Resilience Assessment (DRA) study considered the risks presented by natural hazard events across all Council operated 3 Waters schemes. The original assessment was updated in 2011 using revised hazard and asset behaviour information captured during the 2010- 11 Canterbury earthquake sequence. Risk from natural hazard events on below ground infrastructure is managed using a reticulation vulnerability score which is assessed as part of the (risk based) renewals framework. Above Ground Facilities The above ground facilities were assessed for risk of failure against 13 natural and 2 manmade hazard scenarios. The following risk profile (Table 6) reflects the likelihood of the event occurring and the consequence on the community of the facility failing. Hazards classified as having ‘No Known Risk’ have been omitted from the table. Table 6: Risks to Above Ground Facilities

Wind (150 yr) L
Lightning (100 yr) L
Pandemic (50 yr) M
Terrorism (100 yr) H
E = Extreme, H = High, M = Moderate, L = Low
The scheme is located outside the zone of potential liquefaction thereby reducing possible impact and asset damage from an earthquake event. The facility is rated at high risk from terrorism and is considered moderately resilient to this hazard. The Councils response to these risks is being managed at a district level via the DRA Action Plan and related projects. Refer to the District level AMPs for details.
Trim: 151021144448 Page | 15 3.6 Growth Projections Situation It is anticipated that there will be slight extensions of the water supply beyond the existing scheme boundary. The growth is expected to continue in the southern part of the scheme, and occur in a band around the existing supply area generally to lot sizes of 4 ha. Demand Demand on the West Eyreton water supply scheme is expected to increase by 46% over the ten year 2015-25 Long Term Plan (LTP) period. This projection is based on 52 new lots with restricted connections being established in the next 50 years. The number of restricted (two units per day) connections will be increased by an average of 3 per year during the 2015-25 LTP period to accommodate this demand. Water use demand beyond the 2015-25 LTP period is expected to transition to a lower growth profile defined by past trends resulting in an average of 1 new connections per year (Table 7). Table 7: Growth Projections

Projected Peak Daily Flow (m3/day) 233 279 305 316 328 353
Demand over the next 50 years is projected to increase by 77% for connections and 43% for rating charges. This is a decrease on the Census based growth projection of 190% over 50 years forecast in the 2011 Activity Management Plan. The lower rate of growth for rating charges reflects the 2.0 water units assumed for each new water connection. Water use predictions for the West Eyreton water supply scheme have been based on the standard assumption used when modelling the future water demands within the water distribution models. These are an average and peak daily water use per day of 1,000 litres and 2,500 litres respectively (including losses).

The specific aspects of the scheme that have been considered are the source, treatment, storage, headworks and reticulation system. These are discussed in more detail in the following sections. Source The West Eyreton Water Supply draws water from the following source (Table 8). Table 8: Scheme Sources
Well name Well No. Diameter (mm) Depth (m)
West Eyreton Well 2 M35/9566 200 98.3
The resource consent (CRC100955) was updated in 2009 to reflect the fact this well now feeds two water supply schemes. The daily allowance for abstraction is now 445,000 cubic metres in any year, or 25 L/s or 2,190 m3 per day. As part of the upgrade to supply Summerhill from the West Eyreton bore, a new bore pump was put in, this bore pump has calculated maximum capacity of 15.7 L/s or 1,356 cubic metres per day. The West Eyreton well 1 is now an emergency back-up source to pump into the West Eyreton Reservoirs. A new bore pump was installed in the back-up well as part of the upgrade. The capacity of this well is shown below (Table 9). Table 9: Emergency Backup Source for Scheme
Well name Well No. Capacity (l/sec) Depth (m)
West Eyreton Well 1 M35/0055 8.3 Shallow well
Table 10 presents the projected water demand and associated required source capacity for the West Eyreton bore for both the West Eyreton and Summerhill schemes. Table 10: Project Demand and Required Capacity for West Eyreton and Summerhill Schemes
0yrs 10yrs 20yrs 30yrs 50yrs
Expected Peak Daily Flow (L/s) 9.5 10.7 11.3 11.8 13.0
Required Source Capacity (L/s) 10.6 11.9 12.5 13.1 14.4
The required source capacity was calculated using modelled peak daily flows plus 10% (groundwater usage safety factor). The West Eyreton well was pump tested in January 2009 and it delivered 30 litres per second at a drawdown of approximately 6 metres. The full capacity of the well was estimated at over 50 L/s. Treatment The deep well is a secure groundwater source and therefore the scheme achieves compliance with the microbiological and protozoa requirements of the Drinking Water standards. The well supply is chlorinated in order to provide residual disinfection to reduce the risk of contamination in private tanks. The treatment system (chlorine only) at the emergency backup well provides no protection against protozoan contaminants during the short periods this source may be used.
Trim: 151021144448 Page | 18 Water quality monitoring shows that the West Eyreton water is likely to be moderately plumbosolvent. The definition of plumbosolvent water is water that is able to dissolve lead easily. Water that has low pH and alkalinity tends to be slightly corrosive and therefore plumbosolvent. The principal risk with plumbosolvent water is that metals from pipe fittings can be dissolved into solution and can consequently be ingested by people drinking the water. The health risks from drinking plumbosolvent water are relatively low as very small quantities are ingested and any health effects are chronic, rather than acute. Therefore many years of consumption of plumbosolvent water is required before the risk of adverse health effects are substantially increased. The Council complies with the requirements of the Drinking Water Standards for Plumbosolvency by issuing a notice to consumers twice per year advising them to flush the first 500 mls of water before taking water for drinking purposes. Storage The West Eyreton scheme has two 30 cubic metre tanks which are shared with the Summerhill water supply scheme. The Waimakariri District Council Engineering Code of Practice recommends a minimum storage capacity of 50 cubic metres for restricted schemes. Therefore the existing storage capacity in West Eyreton is sufficient. The following Table presents the required storage capacity.
Trim: 151021144448 Page | 19
Table 11 presents the required storage capacity. Table 11: Required Storage Capacity for Scheme

Required Storage Volume (m3) 50 50 50 50 50
Projected Total Storage Volume (m3) 60 60 60 60 60
Headworks The existing West Eyreton headworks consists of two supply pumps with variable speed drives (VSD’s). The pumps operate as duty-standby and have an estimated capacity of 3.3 L/s. Table 12 presents the projected peak hourly flows for the West Eyreton supply. Table 12: Projected Peak Hourly Flows for Surface Pumps in Scheme
0yrs 10yrs 20yrs 30yrs 50yrs
Expected Peak Hourly Flow (L/s) 2.7 3.5 3.7 3.8 4.1
A new pumpset is expected to be required in 2016 to supply 6 L/s which will provide sufficient capacity for the next 50 years. Reticulation The capacity of the water supply headworks and reticulation has been assessed using an uncalibrated reticulation model. The model and associated monitoring has confirmed that the existing reticulation system has adequate capacity for the existing demands. There are several small growth related reticulation upgrades to the north-east and north-west of the scheme.
Trim: 151021144448 Page | 20 3.8 Summary of Key Points By considering the levels of service, asset condition, risk analysis, growth projections, and capacity assessment, the following key points are noted about the West Eyreton Water Supply Scheme:
Resource The scheme continues to comply with its resource consent conditions. Consents
The water quality source is compliant with the health requirements of the Drinking Water Standards (DWS).
Levels of The current peak daily demand is higher than is desirable but the system Service currently has capacity to cope with the high demand. A number of customers have purchased additional water units, contributing to the high demand.
There scheme exceeds its level of service target for water leakage. The economic level of leakage needs to be determined.
The majority of the scheme is in good condition, but requires an ongoing annual renewals programme to maintain to current standard of infrastructure. Capacity & Performance The scheme is not currently included in a Gazetted Fire District, and there are currently no plans to alter this.
The Risk Assessment did not show any high or extreme risks on this scheme Risk Assessment
The West Eyreton headworks are vulnerable in a large earthquake and also pose Disaster a high security hazard (risk of public interference). Further works are required Resilience to identify future improvements to scheme resilience.
The demand on the scheme is predicted to increase by 77% in connection Growth numbers by 2065. Upgrades of the surface pumps and distribution system will Projections be required to accommodate this growth.
Trim: 151021144448 Page | 21 4 Future Works & Financial Projections (What Do We Need To Do?) This section covers the future works required to meet the target levels of service, maintain the asset in an acceptable condition, reduce the risks to an acceptable level and accommodate growth. 4.1 Operation & Maintenance The current maintenance programme is largely reactive. Over the next three years it is proposed to undertake condition assessments, and then implement appropriate preventative maintenance measures. The maintenance budget has been left at the current level until the long-term maintenance programme has been finalised. The increased expenditure in 2018/19 and 2023/24 is for groundwater certification (Figure 7). Figure 7: Annual Water Operation & Maintenance 10-Year Budget
The primary reasons for the increase in the operation and maintenance budget are related to inflation and growth on the scheme.
Trim: 151021144448 Page | 22 4.2 Renewals Programme Figure 8 shows the renewals budget and depreciation for the next 10 years. A renewals budget of $5,000 per year for West Eyreton was identified from the risk based renewals scoring based on criticality, vulnerability and remaining useful life. This equates to replacing approximately 0.7% of the total reticulation in West Eyreton every year. It should be noted that a renewals budget of $5,000 per year is still greater than the value of reticulation assets reaching the end of their economic lives. Therefore, the renewals expenditure of $5,000 per year will provide a more resilient supply. The renewals have been determined from the risk based renewals model for water supplies. The increased expenditure in 2015/16 is for the renewal component of the West Eyreton headworks upgrade. Figure 8: Annual Water Renewals 10-Year Budget
Trim: 151021144448 Page | 23 4.3 New Works Planned New works are programmed to address the existing deficiencies in the reticulation network and to cater for growth (Figure 9). Figure 9: Annual New Works Budget
Table 13 summarises the projected capital works for the next 50 years. The level of confidence in the budget for the works (High / Medium / Low) is presented in the table. For a more complete discussion on the level of optimisation, refer to the introductory chapter of the AMP. The figures in the table are not adjusted for inflation. Any programme or project that occurs over a number of years, such as the renewals programme, is only shown within the table for the first year in which it occurs.
