Kāpiti Coast District Council provides wastewater collection, treatment and disposal for the residents and businesses of the urban communities of Ōtaki, Waikanae, Paraparaumu and Raumati.
24 hour emergency number: 0800 486 486
The Council owns and maintains more than 15,000 connections and 5,400 access chambers to 310 kilometres of sewers, which handle a volume of 4,025 million litres per year. The Council’s role is to:
All new wastewater (sewer) connections, whether for a new or existing property or subdivision must complete the application form below.
Please Note: Section 459 of The Local Government Act 1974 allows the Council to require a private drain to be connected to the public drain unless it is more than 60m from the public drain.
Clause G13.3.3 of the Building Code states: Where a sewer connection is available the drainage system shall be connected to the sewer and the connection shall be made in a manner that avoids damage to the sewer and is to the approval of the network utility operator.
A computerised monitoring and control system is used to manage all treatment plants and pumping stations except for very small pump stations and those with very high storage capacities, which are monitored manually. All major pump stations have emergency standby generators.
Ōtaki is served by 31 sewage pumping stations which discharge water into the Ōtaki Wastewater Treatment Plant.
The communities of Waikanae, Paraparaumu and Raumati are served by a single wastewater treatment plant in Paraparaumu, which was upgraded in 2001-2002. At that time the oxidation ponds at Waikanae were closed and all Waikanae wastewater pumped to Paraparaumu for treatment.
There are 15 pumping stations in Waikanae and Paraparaumu and Raumati communities are served by 105 pumping stations.
The Paraparaumu Wastewater Treatment Plant operates a Biological Nutrient Removal process, one of the most advanced treatment processes in New Zealand.
Resource consents were granted for 20 years and expire in 2021.
The community of Paekākāriki uses septic tanks. Rural areas of the District rely on on-site disposal; septic tanks or community package wastewater treatment plants.
Investment in the Paraparaumu wastewater treatment plant is required in the coming years to meet the projected growth in the district and renew aging equipment that has been in service since the earlier upgrades. A study was undetaken in 2015-17 to assess the condtion and capacity of the plant and plan out the works required to maintain its performance now and into the future.
The Council provides a network of sanitary sewer mains in the urban areas. A building is connected to the sewer by a 100mm lateral. The lateral is in two parts. The length from the sewer main to the property boundary is owned and maintained by the Council. The length from the building to the boundary is the responsibility of the property owner. These pipes meet and are connected at the inspection point which is located at or near the boundary.
My drain’s blocked – What do I do?
If you have a blocked drain, call a plumber/drain clearer (look under "Drainage" in the Yellow Pages). All plumbers known to the council have been informed of the procedure to follow when called to a blocked drain.
The procedure for the plumber is:
Be prepared: locate a drain clearer (look under "Drainage" in the Yellow pages), and add their contact number to your list of emergency contacts. It's a good idea to discuss costs before agreeing to any work.
