Our water supply network is comprised of 826 km of pipes, 14 pump stations and 7 treatment plants. It would cost approximately $217 million to replace the water supply assets.
We provide a reticulated water supply to the community for domestic, dairy, and agricultural use. The urban areas receive an on-demand supply with surrounding rural areas receiving a restricted supply. Rural areas beyond the Council reticulated systems are reliant on bores or the collection of roof water for their water source.
The water treatment process is different for each of the schemes outlined above, you can find more specific information about the water treatment process in your town by reading section 4: Water Supply Scheme Descriptions of our Three Waters Asset Management Plan.
The following is a broad, generic process of water treatment:
- Water is extracted from the source (e.g., Waikato River),
- Water is pumped to the treatment plant via a pump station,
- The treatment plant uses various treatment process and treats water using its major units, this step also involves chlorination and fluoridation of the water.
- The water is then pumped, or gravity fed to the town reticulation system and reservoirs (please note that some parts of a town may be directly fed from the treatment plant and some parts are reliant on the reservoirs).
We have three agreements in place for water supply:
- Hamilton City Council – providing water for the communities surrounding Hamilton (Southern and Western Districts).
- Te Kauwhata Water Association – Providing water for the Te Kauwhata, Meremere and Rangiriri communities.
- Watercare Services Limited – Providing water to Tuakau and Pokeno.
