Our network

Our treatment plants take raw untreated water, sourced from the district’s bores, springs, streams and the Waikato River and remove contaminants including suspended solids, bacteria, algae, minerals and pollutants. This step also involves chlorination and fluoridation of the water.

The end result is treated (potable) drinking water, which is safe to drink. Waikato district's water comes from a variety of sources and so a range of water treatment processes are used at individual plants. 

Each treatment plant or water scheme are designed to deal with the characteristics of the source of supply. 

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

Fluoridating water greatly reduces rates of preventable tooth decay and is a proven public health measure to improve overall oral health.

Fluoride is added to council water supplies in Ngaaruawaahia, Huntly, Te Kauwhata, Southern Districts, Pookeno and Tuakau. No fluoride is added to water supplies at Raglan, Te Aakau, Onewhero and Port Waikato. 

Fluoridating Raglan Drinking Water Supply

The Ministry of Health and Taumata Arowai (as the new economic regulator) are implementing the fluoridation of drinking water for water supplies that service over 500 people under the (Fluoridation of Drinking Water) Amendment Act 2021.

Across the Waikato District, our larger schemes already provide fluoridated drinking water, and we have received notification from the Ministry of Health that the Raglan supply will be issued directions for fluoridation in the near future.

The below letter outlines the next steps from the Ministry of Health Director General for Waikato District Council and other Territorial Authorities who will be required to implement fluoridation.

A rain tank will require a building consent if:

• the tank will supply roof water to the house
• the Council mains will be plumbed to the tank (eg, backup supply)
• the tank exceeds 35,000L
• the tank exceeds 2,000L and is more than two metres above ground or
• the tank exceeds 500L and is more than four metres above ground.

Unless the tank exceeds the size limits above, installing a rain tank for garden irrigation does not require a building consent.

These criteria apply to both new premises and when retrofitting a tank to an existing property. If a consent is required, it can be included as part of the overall building consent.

Stormwater attenuation tanks

If you need one of these, it is possible to combine the rainwater tank and stormwater attenuation tank, but the volume of the tank needed should be the sum of the two levels for each function being handled by the combined tank.

The top part of the tank drains quickly to buffer storm flows and the bottom saves water for recycling.

You can contact Council and arrange to have the flow restrictor removed for a short time to let the tank refill.

If your tank runs dry during summer due to high consumption, we suggest you increase your water storage capacity and check for any potential leaks.
