Wastewater Project, Coromandel, New Zealand
Eastern Seaboard Wastewater Project
Scope: The key objectives of the project were to provide for future growth of the peninsula, improve the quality of wastewater and protect the waterways, estuaries and harbours for the townships of Whangamata, Pananui and Whitianga.
The project involved the design, construction, installation, commissioning and operation of wastewater treatment plants for three major resort towns located on the eastern seaboard of the Coromandel peninsula. These towns have an average population of between 4,000 to 6,000 people, peaking at around 50,000 over the summer holiday season.
Services Provided: New Zealand’s largest ever wastewater project of three new wastewater treatment plants, were constructed adjacent to, or on the site of existing plants, requiring service diversions to keep existing plants operational during construction. The three plants feature an identical treatment system and share common equipment and similar layouts. The plants meet the strictest discharge consents in New Zealand and have some of the highest treatment standards in the world.
The project has received a number of awards, including the Orica Chemnet Operations Award 2008 from Water New Zealand, and the Silver Award of Excellence 2009 from the Association of Consulting Engineers, New Zealand.
