Aqua Gratis has been created to significantly reduce domestic water consumption. Capturing and reusing the bath and shower water to flush in up to four toilets in the home gives at least a 30% saving on potable water supplied to the home. The use of greywater for flushing toilets saves around 200 litres a day for a family of 4. Unlike rainwater harvesting, this solution has a regular supply of water. This solution is low cost, easy to fit, use and maintain. This product which will benefit the water companies, developers, occupiers and the environment. Aqua Gratis will reduce domestic sewage by 30%. This will reduce energy used to process both water supplied and sewage treated. With 13% greater Co2 savings than its mainstream competitor. Aqua Gratis is the missing element of zero carbon homes.
