Plant & Equip Washing

City West Water Depot

The problem

The stormwater system cannot receive polluted wash water and the sewer network is not designed to receive increased loadings during rainfall events

Clean Rainwater falling on the catchment is directed away via the stormwater network

Polluted vehicle and equipment wash water arriving on the pavement needs to be directed to an onsite wastewater capture and pre-treatment system pre discharging to sewer

The Application

Unroofed Vehicle and Equipment Washing

The Solution

Installation of a Model No. FE/LH/FF600 Diversion System

The system includes a proprietary control panel and hydraulically (water) driven waste water/stormwater diversion system in a proprietary Roto moulded MDPE pit.

The System Function

During day to day operation absent vehicle and equipment washing the diversion valves are activated to direct clean rainwater discharge to the stormwater network

When plant and equipment washing commences the interfaced hydraulic (water) drive line opens the trade waste diversion valve directing the polluted water stream to the onsite waste water pre-
treatment plant

When washing ceases the system harvests a pre-programmed volume of wash down water residue (referred to as the first flush) and sends it to the treatment plant,

The system then defaults to clean water discharge to stormwater mode until wash down water is again activated
