Overv​i​​​​ew

The availability of clean safe to drink water and the safe disposal of wastewater are fundamental to the health and welfare of the Selwyn community.  The 5 Waters service provides clean safe to drink water for households and removal of wastewater and rain water in a way that protects the health of the population and natural environment.  The 5 Waters service also provides river water for livestock and drains certain land so that it is usable for agriculture. These services are provided through 76 separately rated water-based schemes within the District, as shown above.  The 5 Waters assets are valued at a total of $728 million. Water supply assets are valued at $184 million, wastewater schemes $311 million, stormwater $70 million, land drainage $45 million and water races $118 million.

Drinking water is provided by the Council to 78% of the population of the District. By comparison, wastewater services are provided to approximately 62% of the District.  The largest consented wastewater treatment and disposal area is the Pines Wastewater Treatment Plant, servicing Rolleston, West Melton, Lincoln, Prebbleton and Springston (the Eastern Selwyn Sewage Scheme). In 2021, Council are consulting on whether to join the Ellesmere Sewage Scheme to Pines Wastewater Treatment Plant, creating a larger scheme (the Selwyn Sewage Scheme).

It has always been clear that the water services are interlinked, if not directly, then via natural pathways.  This reflects the unique geographical 'mountains to sea' layout of the Selwyn District.  There is a strong connection between these services and it is essential that they are looked after.  The Council's approach is to manage the 5 Waters activities in an integrated way.​


Why is the Counc​​il involved?

The Council is in the best position to respond to the expectations of the communities it serves and to translate these needs into levels of service, which have funding options accompanying them, for public scrutiny and comment.  The Local Government Act 2002 clearly sets out how the Council must consult with residents over significant decisions and this ensures the community has a major decision making role.  The 5 Waters assets are listed as 'Strategic' in this 2021/2031 Long Term Plan for the very reason that failure of these services has a devastating and far-reaching effect on the District.  The Council is well positioned to take a major leadership role in planning and managing the assets and networks that deliver these essential services.

By managing all of the 5 Waters activities, the Council can plan ahead in a coordinated way and take advantage of the opportunities to introduce new initiatives e.g. the potential in the future to use treated wastewater to irrigate reserves, if this is feasible and acceptable to the public.  When prioritising across the 5 Waters activities, opportunities to combine projects will become apparent. This coordination brings better results than a fragmented approach, which could occur if the activities were separately managed, especially by more than one provider.

There is also the need to comply with a raft of legislative and statutory processes, which the Council recognises in its strategic plan, policies, education programmes, and commitment to sustainable practices. 

The security of the District's water supply is paramount as our communities require reliable, clean, safe water to serve their day-to-day needs.  These water-related activities also protect and sustain the health of the environment, particularly the sensitive Te Waihora (Lake Ellesmere) catchment, by responsibly dealing with wastewater and the draining and disposing of groundwater and excess stormwater run-off.

The wastewater infrastructure is expected to continue to increase rapidly with the predicted growth in the eastern portion of the district.  Stormwater assets have been, and will continue to be, rapidly developed to meet the increased standards reflected in the Regional Council's Land and Water Regional Plan rules.​


Activity goal​

Selwyn District Council's goal for the 5 Waters activities is:

'To provide water services that meet all relevant standards and are at a service level the public can afford and have confidence in, now and into the future'.​


Council contributi​​​on to community outcomes

This activity contributes to the following community outcomes:

  • A clean environment
  • A rural district
  • A healthy community
  • A safe place in which to live, work and play
  • An educated community
  • A prosperous community
  • A community which values its culture and heritage​

The 5 Waters Activity Contribution t​​o Community Outcomes

Key Community Outcome​ Community Outcomes How 5Waters Services Contributes
A clean environment
Air, land, water and general environment to be kept in a healthy condition. Manage the 5 Waters activities in a way that minimises their potential adverse impact on the environment.
A rural districtA living environment where the rural identity of Selwyn is maintained Provide water races and land drainage systems that are part of the rural landscape and contribute to the ability to use rural land for agriculture. 
A healthy community ​
We have appropriate health, social and community services & they are accessible to all residents of the district. Provide water, wastewater and drainage services necessary to support community and public health services.  There is potential to provide for recreational opportunities in conjunction with stormwater management strategies.
We have access to drinking water that helps protect their health. Provide safe drinking water for all water schemes within the Selwyn district.
A safe place in which to live, work and play ​​
We are safe at home and in the community.
Provide safe drinking water and effective wastewater removal and disposal as well as removal of stormwater and excess groundwater (via land drainage).
​We maintain a coordinated and effective response to, and recover from, emergency and disaster events.
Respond to emergency events by providing safe drinking water and effective wastewater removal and disposal as well as removal of stormwater and excess groundwater (via land drainage).​
An educated community
Our district provides a range of quality, lifelong education and training opportunities. Provide water, wastewater and drainage services necessary to support education facili​​​​​ties. 
A prosperous communitySelwyn has a strong economy which fits within and complements the environmental, social and cultural environment of the district. Provide business with water, wastewater and drainage services, sometimes to a higher standard or with a higher level of reliability than regular domestic services.  Effective water races and land drainage systems are essential for productive use of land.
A community which values its culture and heritageOur district provides a range of arts and cultural experiences and facilities.  Local history and heritage is preserved, shared and promoted Provide water, wastewater and drainage services for cultural activities.  All 5Waters activities can impact on the cultural and heritage values and need to be managed to minimise adverse effects.

 

Negative effects on the wellbeing of the community​​​​​​​

Carrying out activities associated with water and land has the potential to be damaging.  The Council recognises these possible negative effects and takes the following measures to address them.

Well-being Possible / negative effect The Council's response is to
Social ​​​ ​​

Drinking water or poor sanitation may cause serious illness.Regularly monitor and measure water and groundwater E.coli levels to ensure that safe levels are achieved and maintained.
Floodwaters may also carry contaminants hazardous to health.Remove and dispose of wastewater effectively and safely without overflows causing flooding or contamination.  Manage stormwater to minimise flooding.
Poorly designed, operated or located infrastructure may cause noise, odour, visual or other impacts which have adverse effects on quality of life.Design and locate new infrastructure and use buffer zones and planting in a way that reduces the effects of potentially disruptive assets. 
Failure to secure assets which subsequently cause physical harm or loss of life.Regular health, safety and environmental audits of assets, implementation of national standards and appropriate 'design' standards.
Economic ​​ ​
Charges have to be levied to cover the cost of providing services that meet the Council's goals and its statutory obligations while remaining sustainable.Responsibly provide efficient and effective levels of service that the community can afford.  Provide a range of services with associated costs so people can make informed choices.
Failure to levy charges at the appropriate time may result in an excessive burden for future generations.Consider 'whole of life' costs and apportion capital costs equitably over time.  Ensure that charges are realistic and do not result in accumulated costs later.
Ineffective land drainage may damage crops or result in loss of productivity.
Manage system to minimise flooding.
​Failure to make adequate service provision together with unreliable services may limit growth and impact on economic prosperity.
​Plan ahead for economic growth and population expansion.  Carry out renewals and new works in a timely manner and fund capital works for growth through development contributions.
Environmental ​​​
The activity has the potential to lower air quality, water quality and quantity and the health of soil and biodiversity.
Avoid, remedy and mitigate adverse effects and strictly adhere to Resource Consent conditions by monitoring before and after works and installations.  Take corrective action if problems arise.
​The activity is very high in its use of energy (approximately half the Council's usage). ​

Choose assets and networks which are energy efficient and explore alternative sources of energy.  The Council uses turbines and solar panels for energy and runs generators powered by diesel instead of electricity.
Encourage open stormwater systems with accompanying riparian vegetation and tree planting (as opposed to pipes) to reduce the carbon footprint and to treat stormwater before it enters waterways.
Keep up to date with the latest technology and ideas.
Water races take water from rivers and there is considerable seepage to ground from the races.Water races are closed when they are no longer needed for farming purposes or for amenity.  It is recognised that the water which seeps into the ground is not 'lost' but replenishes groundwater.  Shallow wells can benefit from this top-up.
Cultural ​
The activity's services have the potential to cause damage to heritage sites, artefacts, other structures, landscape features and waterways.Assess the impact on cultural well-being as a normal part of the decision-making process.  Site and locate structures and services sensitively in the landscape and manage them responsibly.
The pollution of groundwater and surface water is an important cultural issue.Consult with Tangata Whenua and with the Historic Places Trust early on to avoid disturbances and destruction of important items and features.

 

Planning Ahead

Over the next 10 years there are a number of key challenges for the 5 Waters. These challenges and how we plan to respond is sent out in the table below. 

Challenge​ How we plan to respond​
​An increasing population will increase demand for water services​Develop and continually review master planning for water infrastructure to ensure the demand for water services is met for our growing communities 
​Changes to underlying regulatory framework​Responding to changing regulating framework including 3 Waters reform, RMA Reform, National Policy statements, and the formation of Taumata Arowai – Three Waters Regulator.
​Responding to community demands for higher levels of service 

​Continue to deliver infrastructure improvements

Take a rigorous approach to assessing, planning, and delivering maintenance and repair works 

 

Demand and A​sset Management

The 5 Waters activities physical assets consist of below-ground services including pipes, wells, pump stations and wastewater treatment equipment and above-ground facilities including pumps, reservoirs, intakes, open channels and land disposal areas.

Asset Management practices have been measured against appropriate international practice guidelines.  The Council is aiming to achieve an intermediate level of asset management practice within the period of this LTP.​

Where relevant, we have assessed the impact of changing demand for the 5 Waters activities.  This is more relevant in water and wastewater, and to a lesser extent stormwater, land drainage activities and water race activities.​

Demand Mana​​gement

Based on current community growth trends, demand for water, wastewater and stormwater services has the potential to exceed consented and capacity allowances in some schemes.  This analysis is based on the Council's population information, a detailed review of historical records and forward predictions of use, after factoring in potential climate changes and energy costs as well as engineering staff / contractor knowledge.

Achieving reasonable usage, particularly in the areas of water (human drinking water and stock water) together with wastewater treatment and disposal is a key factor in this LTP.  In particular, the need to ensure that water is used wisely sits above all other issues in the operations and maintenance sphere.  The strong relationships between water use and wastewater disposal, stormwater, water race and land drainage systems have been provided for in integrated projects.​

Our main townships of Lincoln, Prebbleton, Rolleston and West Melton will experience considerable growth.  These townships, in particular, are subject to detailed demand planning and will require either new consents/wells or where allowance has already been made, additional new infrastructure to deliver/dispose of the water stream.  The section on significant projects identified the expected level of works to be undertaken.  Over time, existing parts of townships are expected to upgrade their stormwater services to meet consenting limits and requirements.

Projects which assist in passive (e.g. education), and active demand management are identified.  The outcome sought is to meet environmentally driven consent constraints while providing an appropriate level of service.

Council are actively implementing a Water Demand Management Strategy which has included the installation of water meters and implementation of volumetric water charging.​

Infrastructure Sustainability

The 5 Waters activities are mutually interdependent and the Council will provide the extent and quality of service demanded by the community and legislation, now and in the future, in an integrated way.  This involves prudently managing the acquisition, maintenance, operation, renewal and disposal of water assets in ways that optimise the value of services delivered to the community.

Infrastructure sustainability is a core part of the Councils vision for successful asset management. This will be achieved through ensuring that:

  • Growth and demand is monitored to ensure a timely provision of infrastructure
  • Vested assets are fit for immediate and long term community needs
  • Assets are maintained and renewed to meet the needs of current and future generations
  • Natural resources are managed responsibly and sustainably.

Council is aware of the potential impact that climate change has on its five waters and is actively monitoring and planning for this.


Water and sanitary a​ssessment

In 2006 Council adopted its first Water and Sanitary Services assessment.  The review of the Water and Sanitary Services Assessment occurred in 2017/18 and is reported in the 2018-2028 5 Waters Activity Management Plan. The assessment will be reviewed again before the end of the 2021/2031 LTP period.

The assessment covers water, wastewater and stormwater (including land drainage services). There have been significant improvements since 2006, particularly in:


Wastewat​​er

  • The Council is migrating onsite serviced properties within township reticulated areas to the network.  Council has also been assessing the requirements for installing reticulated networks within townships which currently rely on onsite wastewater disposal (e.g. Darfield and Kirwee).
  • The Selwyn Sewage Scheme and Ellesmere Sewage Scheme have been and are programed for further upgrading to service the connected growing communities.
  • Council are consulting on the possibility of connecting the Ellesmere scheme to the Pines wastewater treatment plant (Selwyn Sewerage Scheme), to allow a higher treatment standard to be achieved.
  • The standard of wastewater quality at the point of disposal continues to be a focus for Council.

Water Supply​

  • Water Safety Plans are in place for all schemes, with improvements in water quality underway or allowed for in the budget.
  • Council water supplies were monitored in 2019/20. 99.96% of all samples from the treatment plants and 99.72% of samples from the reticulation were compliant for E. coli. 

Stormwater (and land drainage)

  • Stormwater systems are being installed at the time of subdivision and the quantity at discharge is improving as confirmed by measurement.​


Major proje​​cts

The table below shows the major projects planned within the 2021 - 2031 LTP.  The projects will serve growth, extend wastewater services to currently unreticulated communities and improve the level of service of water supply, wastewater and stormwater systems.

​Major Project Year​ ​Cost and Funding
​Selwyn Sewage Scheme (SSS) - Development of the Pines Waste Water Treatment Plant​2021 - 2031
​$30m funded by development contributions and sewerage rates
​Selwyn Sewage Scheme (SSS) – Construction of the Darfield wastewater pipeline to Pines ​2021 - 2022​$12m funded by Government grant, development contributions and sewerage rates
​Selwyn Sewage Scheme (SSS) – Construction of the Ellesmere wastewater pipeline to Pines​2023 - 2024​$9m funded by development contributions and sewerage rates
​Water supply quality and Level of Service upgrades ​2021 - 2031​$24m funded by water rates
​Water Supply Capacity Upgrades for Growth​2021 - 2031​$23 m funded by development contributions, fees and charges and water rates
​Stormwater flood protection and Capacity Upgrades​2021 - 2031​$7m funded by the stormwater rate

  

Other major projects and decisions include:

  • Keeping our drinking water safe – we're proposing to continue our current approach to maintaining safe water supplies, which meet community expectations, and comply with expected new regulations.
  • Continue with a risk based approach to water supply management.  High risk supplies will be chlorinated.  Other treatment methods include UV treatment and filtration.
  • Funding our drinking water supply – we're proposing to change the way we charge for the supply of drinking water, to meet increasing costs and to help manage our high water demand. This may be through options for increasing the volumetric (metered) water rate and the annual fixed rate.
  • Expanding the Pines Wastewater Treatment Plant capacity from 60,000 to 120,000 population equivalents to provide for the connection of a new wastewater system in Darfield and Kirwee and the existing Ellesmere wastewater network.
  • Progress the development and implementation of stormwater catchment management plans for all townships.
  • Work with Central Plains Water and other third parties to develop shared water services / infrastructure where such ventures provide benefit to and are supported by Council.
  • Investigate and implement opportunities to improve water supply scheme efficiency and resilience through scheme interconnections.
  • Progress ratepayer initiated water race closures to public consultation once approved by Council.  The Council will consider ratepayer initiated closures once 80% written support from directly affected property owners is obtained.  All closures are subject to Council approval.  Council initiated race closure will also occur over this LTP period.
  • Work towards the closure of the Upper Ellesmere Water Race network.
  • Work with Environment Canterbury and key stakeholders to realise opportunities to use consented stock water for environmental enhancement including targeted stream augmentation and habitat enhancement.
  • Review rating and governance structure of all land drainage schemes in consultation with the land drainage committees.
  • Engage with the 3 Waters Reform programme underway by central government.
