Hippo the Water Saver is a simple, proven and low-cost water saving device which helps conserve water in toilet cisterns. The Hippo 9 saves up to 3 litres of water every time the toilet is flushed, and is ideal for older toilets. Made from durable, heavy gauge polyethylene, the Hippo bag opens in a box-shape underneath the large cistern float. When the toilet is flushed, the water confined within the Hippo is the volume saved.
On average, an employee uses the toilet in the workplace three times a day. Over the working year, this amounts to 6,000 litres of water. Since 1997, 10 million Hippos have been sold worldwide with a combined daily water-saving equivalent to 27 Olympic size swimming pools.
