Hornsby Shire Council Epping Oval Stormwater Harvesting Design, Construction & Commissioning

Optimal Stormwater was engaged to provide $1.2M worth of stormwater harvesting works in Hornsby. Optimal Stormwater was selected because of our depth of understanding in regards to the water balance and limitations with the concept put forward. The design increased catchment area, eliminated unnecessary infrastructure and improved ease/reliability of ongoing operation.
The projects involved: water balances, survey, revised concept design, revised storage design, moving the offtake, appropriate primary treatment, secondary treatment, disinfection, innovative storage, design, drawings, project management, construction, installation, plumbing, electrical, control system design, commissioning and O&M manuals and instructions.

The projects are treating catchment areas of 4ha, 5ha and 280ha! Each site required a different solution when it comes to the offtake, capture and primary treatment. But we have sought to provide consistency where possible and have used similar pumps and storage designs to achieve that.
