POTABLE WATER FOR REMOTE COMMUNITY

BACKGROUND

The Government of Western Australia (WA) Housing Authority manages essential services at Aboriginal communities in the remote outback of WA via the Remote Area Essential Services Program (RAESP). Local Regional Service Providers are engaged by Housing Authority for the delivery of essential services to these communities.

The Cosmo Newberry Aboriginal Community potable water supply had nitrate levels that exceeded the health limit, and with a number of MAK Water treatment plants at other aboriginal communities, MAK Water was asked to supply an additional water treatment plant. The client was looking for a fully automated, extremely reliable, low maintenance system, to achieve compliance with the Australian Drinking Water Guidelines (ADWG).
