The reticulated water supply is provided through a network of intake structures, reservoirs, pump stations and an extensive underground pipe network. This water is used by rural and urban areas for domestic and industrial purposes. 

We operate nine water treatment plants and 30 reservoirs with a total capacity of over 19,000 cubic metres.

We have three external agreements in place for water supply:

  • Hamilton City Council agreement is in place to take up to 12,000 cubic metres per day for the southern parts of our district.
  • Te Kauwhata Water Association agreement is in place to take up to 4,000 cubic metres per day of raw water for the Te Kauwhata, Meremere and Rangiriri communities, 
  • We have an agreement with Watercare Ltd to supply water to Pokeno and Tuakau. Tuakau is due to be supplied by Watercare this year.

We maintain over 700 km of pipelines providing over 13,000 properties with a reticulated water service.

Flow restrictors

Many in our district will have a flow restrictor placed within their meter, this limits the amount of water that passes through the trickle feed system to 1.8 cubic Meters a day, 1.3 liters a minute.

Customers can request to have the flow restrictors removed from their water supply for up to four months. The flow restrictor is removed to supply full flow water while a storage tank and pump equipment is installed on the property, usually during a building project.

Our treatment process

We currently operate nine water treatment plants supplying drinking water to over 13,000 customers. Each plant takes untreated water and removes contaminants including suspended solids, bacteria, algae, minerals and pollutants. The end result is treated drinking water - ('potable' water which is safe to drink). 

Water, raw and untreated, is sourced from the district's bores, springs, streams and the Waikato River. Groundwater sources typically require less treatment than surface water as the raw water contains less microbiological organisms and it's not as 'stirred up' (it has low turbidity).

Registered water carriers

Customers should always check that water supplies are coming from a council and district health board-registered carrier. This is to ensure that the water supplied is 'potable water' - water that is safe for human consumption.
