Background
To maximise the efficiency of wash down operations at its Brisbane Barracks, the Department of Defence decided to consolidate 18 vehicle and equipment wash down stations into one facility.
Key operational goals for the project included minimising town water consumption, reducing load on the sewerage treatment system and ensuring all relevant environmental and occupation health and safety requirements were met.
Solution
MAK Water was selected to design, manufacture, install and commission a water recycling system for the new consolidated facility, working in partnership with consulting engineers and the Department of Defence.
The system is flexible enough to wash as little as a single vehicle per day through to more than 200 large vehicles per day.
MAK Water Key Solutions
Dissolved air floatation wash bay Water Recycling System
- The recycling system is capable of treating up to 80,000 L/h of wash down water.
- The system removes oil and grease from the water and filters and disinfects the water making it safe to reuse for vehicle wash down.
Rainwater Harvesting System - To make the site water self-sufficient, and account for evaporation and carry over water losses, a rain water harvesting system was included to harvest water from the hardstand area, treat it and use it to top up the wash bay system.
- A recycling system capable of treating 10,000L per hour of wash down water
- Hydroxide precipitation, flocculation and DAF clarification removes silt, heavy metals, seeds, weeds and pests from the water
- Filters and disinfects the water to ensure it meets safe water and occupational health and safety requirements to reuse for vehicle and equipment wash down
- Supply and onsite installation of interconnecting pipework and electrical
- Fast 10-12 week delivery time
- Onsite commissioning and training of local operators, with ongoing service and maintenance agreement
Results and benefits
- Facility consolidation. Consolidation of 18 wash down points to one central facility.
- No need to use potable town water. Elimination of the use of potable town water for vehicle wash down.
- Environmental protection. Protection of the sewer and storm water systems from wash down water volumes and contaminants.
