An open letter from Kaipara District Council to the Mangawhai Community Wastewater Scheme (MCWWS) Advisory Panel

You may recall Council appointed a group of ratepayers from within the Mangawhai community to undertake a review of the MCWWS. Called the Community Advisory Panel, they were to provide independent and objective input into Council’s decision-making processes around the possible extension of the MCWWS. Council received the Panel’s report in July 2015. In response to the Panel’s Report and specifically the 22 recommendations given, please view the open letter to find the Council's responses, clustered under theme headings.

Project Overview

The MCWWS services part of the Mangawhai Drainage District through a reticulated network of pipes connecting properties to the treatment plant. A further network of pipes connects the plant to a holding dam on Browns Road Farm.

Disposal occurs through a further network of pipes on the Farm that distributes treated water on fields covering part of available farmland. The capacity of the plant can cater for about twice the number of current connections. Disposal capacity through the current irrigation reticulation is at its limit. In order to increase connections to the plant, the reticulation needs to be extended to other parts of the drainage area and the disposal capacity needs to also increase.

There are a number of options for how the reticulation network is extended, how the capacity for disposal is increased and how the extension is funded.

Decisions on the preferred option are required. These decisions will be made with input from a community-based Advisory Panel.
