Oxford Cold Storage uses 200 kilolitres of water every day for their evaporative cooling systems. With concerns about long term water supply and threat of price increases they applied for funding from the Australian Industry Group for a feasibility study to ascertain how water could be sourced from roofs and plant buildings.
The study showed that 62% of potable water needs could be met by capturing water from the two roof areas (based on average yearly rainfall) saving almost $26,000 in annual water costs in addition to the benefits for the environment.
Cost of implementation was estimated at $600,000 with initial payback period of 23 years; primarily:
- Installation of 28 tanks
- New pipe works
- Configuration of existing pipes
- Centralised computer control of valves
They received a $300,000 grant from City West Water and the Dept of Innovation, Industry and Regional Development making the project economically viable.
