Operation & Maintenance

With drought conditions (or water emergency) upon us again Optimal Stormwater encourage sustainability and operations managers to contact our fully resourced stormwater harvesting team developed specifically to operate and manage public and private water utilities.

We are currently operating over 100 sustainable water projects including stormwater and rainwater harvesting, groundwater supply, leachate treatment and reuses and wastewater treatment and reuse.

We understand the value of water, where and how to source it and the most economic design for application and demand. Optimal were invited to draft the ACT Standards for Stormwater Harvesting and Reuse – the first of its kind which has been tested on the $20million ACT Stormwater Management Amplification program. Here are just a few of the project we are currently involved in.
