COOK ISLANDS – WATER QUALITY DATA EVALUATION PROGRAMME

COOK ISLANDS – WATER QUALITY DATA EVALUATION PROGRAMME

Client: Cook Islands Government

Industry: Wastewater Treatment and Disposal

Services: Water quality data evaluation and Guidelines

Background:

The Cook Islands Government has initiated the Sanitation Upgrade Programme to improve sanitation in the Cook Islands.

The Muri-Avana area of Rarotonga was the project pilot area under the Waste Management and Sanitation Improvement (WMI) Programme where upgrades to domestic based wastewater treatment systems were undertaken to meet the standards of the Public Health (Sewage) Regulations 2008 and associated code.  The upgrade work on household sanitation systems is now complete.

As part of the pilot WMI Programme (and follow on project) data is being gathered to understand the effect of the upgrades on receiving water quality.

Assignment

ARGO was engaged to analyse water quality data for each of the test sites (intakes on the reservoirs, streams, reef, and lagoon) supported by field sheets, probe data, rainfall data and any other data as necessary, with the objective of identifying water quality changes or trends if any, after the upgrading of domestic wastewater treatment systems, comparing results with Guidelines and preparing ongoing interpretative tools.
