The first facility in Australia attempting to harvest and treat stormwater to a standard acceptable for direct injection into the drinking water system.

The Kalkallo Stormwater Harvesting and Reuse Scheme is the first facility in Australia attempting to harvest and treat stormwater to a standard acceptable for direct injection into the drinking water system. The facility is located in the major green field development of Merrifield, next to the existing township of Kalkallo in Melbourne’s northern development corridor. The facility includes:

• A 65ML stormwater storage basin located downstream for the stormwater collection system and wetlands of a 160ha area of the Merrifield development.
• A treatment plant designed to process up to 1ML/day to drinking water standards.
• The facility was completed in 2014, but is yet to commence operating due to development delays which have impacted the amount of stormwater available.
