Water supply schemes

The Council, through its 16 water supply schemes, supplies water to about  85% of the district’s population. Of the 16 water supply schemes that the Council operates, seven of these are urban on-demand schemes and nine are restricted supplies. 

On-demand supplies

On-demand supplies are for larger urban areas. On-demand means that customers draw water directly from the Council’s water mains, without needing a water tank on their property.

The on-demand supplies are Cust, Kaiapoi (including Pines/Kairaki), Oxford Urban, Pegasus, Rangiora, Waikuku Beach and Woodend. These schemes, although on-demand, have some restricted connections for adjoining rural properties.

Although these supplies are on-demand, there may be times when it is necessary for customers to conserve water.  For information on how to conserve water, refer to the Water Conservation page.

Restricted supplies

Restricted supplies are generally for rural properties where on-demand supply is not possible. On these supplies, only an agreed volume of water is supplied to the customer's individual storage tank each day.

The restricted supplies are Garrymere, Fernside, Ohoka, Oxford Rural No. 1, Oxford Rural No. 2, Mandeville, Poyntzs Road, Summerhill and West Eyreton.

If you are on a restricted supply, all your water will be supplied through a restrictor fitted to the service pipe to the on-site storage tank on your property. However, some properties on Ohoka, Poyntzs Road and Garrymere schemes have a 13 l/m restrictor where an on-site tank is not required. Water will be supplied at a lower pressure compared to on-demand supplies.
