Save Water Through Rainwater and Stormwater Harvesting

Rainwater harvesting is a great way to save precious drinking water and reduce your organisation’s water bill.

Harvested rainwater can be used in place of drinking water in many different functional areas across your business including toilets, gardens, fire testing, cooling towers and manufacturing.

This section contains some case studies from businesses that have used rainwater harvesting to save water and meet their waterMAP requirements.

Rainwater Harvesting At Cadbury Schweppes

The new harvesting system has successfully reduced Cadbury Schweppes’ reliance on drinking water by an estimated 7.5 million litres per year. Rainwater is now collected and used primarily for the site’s cooling towers. It can also be used in toilets and for irrigating garden beds when available. Download the PDF for the full case study.

Washbay Water Recovery At Mobil

Mobil developed a plan to install rainwater tanks and a silt trap that had the dual benefit of collecting rain water and reusing washbay water. Mobil then applied for, and was awarded, a cleaner production co-funding grant worth $20,000 of the total $40,000 funding costs. Download the PDF for the full case study.
