Water Supply Zones

Contents

​Background

Because of the District's large geographical area, Council operates the water supply network in three zones: Western, Central and Eastern.

The Western and Central zones are linked to help manage supply during peak demand times. Water is gravity fed from bore fields and reservoirs to lower lying areas and coastal communities. Major side roads have supply pipes boosted by pressure pump stations.

In the Eastern zone water can be moved around to meet demand. Several pump stations boost pressure to serve homes located higher into the hills.

In addition to the water sources, Council’s water supply network includes 10 treatment plants, 24 reservoir and tank sites, 24 booster pump stations and 660km of pipes.

Eastern Water Supply

The Eastern Supply Zone (ESZ) is made up of three raw water supplies supporting the urban areas of Te Puke, Maketu, Paengaroa and Pukehina plus and the rural areas surrounding all of these centres.

Our Focus

We will continue to supply quality water while:

  • Investigating additional bore at Youngson Road or Ohourere to continue to meet demand.

  • Upgrading water feeder main to Omokoroa

  • Moving toward improving security and quality of water supply.

    Investigation for an additional reservoir for the Central Sypply Zone at a position to best serve the network is required.

Western Water Supply

The Western Supply Zone (WSZ) is made up of three raw water supplies supporting the urban areas of Waihi Beach, Island View, Bowentown, Athenree and Katikati, and the rural areas of Aongatete and Tahawai.

Our Focus

We will continue to supply quality water while:

  • Progressively upgrading and replacing old reticulation

  • Moving toward improving security and quality of water supply

All water is treated and supplied from storage reservoirs or direct from treatment plants.

 

GLOBALGAP (formerly known as EuroGap)

The Euro-Retailer Produce Working Group (EUREP) has produced a framework for Good Agricultural Practice (GAP) on farms which defines essential elements for the development of best-practice for production of horticultural products (e.g. fruits, vegetables, potatoes, salads, cut flowers and nursery stock). It also defines the minimum standard acceptable to leading retail distributors of horticultural products in Europe.

The Western Bay of Plenty District Council has provided documents for Section 7 Irrigation (parts c & d) for horticulturalists that are using water supplied by Council. This information includes answers to questions contained in Section 7, as well as raw water monitoring reports, and treated water monitoring results. The reports relate to specific water supply areas so horticulturalists will need to retrieve the information based on the location of their orchard.
