Water efficient appliances: As with energy efficiency, when replacing appliances for the kitchen and other areas, it is recommended that the proprietor purchases appliances that are rated A for water efficiency.
Bedrooms: Showers are better than baths because the average shower uses 35 litres of water and the average bath uses 80 litres. The company could consider introducing water saving eco-shower heads to further reduce water use. They operate at about 7.5 litre/minute, instead of 15 litres/minute.

Taps: We recommend either percussion taps or spray taps to minimise water use. Percussion taps switch themselves off and spray taps use one quarter of the water of regular taps.

Or try spray tap inserts e.g. that screw into the existing tap head. See also Flow restrictors and taps operated by motion detector.

Dripping taps should be checked for regularly because a dripping tap can lose a litre of water per hour and multiplied out by several taps over a long period

Toilets: Older toilets use 9 litres per flush compared to around 4 to 6 litres per flush in modern dual flush toilets. The best modern toilets are the IFO CERA ES4 that operates a full flush of 4.5 litres. The flush volume can be reduced in older toilets by installing Save-a-flush devices or hippos into toilet cisterns. They reduce the flush volume and lower water use. A number of Save-a flush’s can be obtained free from United Utilities on 0845 746 2200.

Urinals: In order to save water in public toilets we recommend the installation of Urinal flush controllers. Passive Infrared Detectors (PIR’s) can be fitted to urinals so that they only flush when movement is detected rather than at 20 minute intervals.

Other alternatives are manual flush urinals or waterless urinals. Waterless urinals have a chemical disinfectant in a special trap that acts as a deodorising odour barrier.
Water butts that use rainwater intercepted from the guttering system can be used to water plants and for outdoor cleaning, saving water in the process. Under the Water Industry Act 1991, Water Companies have a duty to promote the efficient use of water by their customers. Subsidised water butts can be obtained from United Utilities

Rainwater Harvesting: This system operates by collecting water from roofs, storing it in an underground tank and pumping it up to a feeder tank. More commonly an on-demand pump is used to supply water from the rainwater tank to wherever there is a demand for the water.

A rain harvesting system can provide water to replace up to 50% of mains supply for non-potable water use. Toilets, washing machines and garden watering can all use water from the rainwater system. The pipe work for rainwater should be clearly marked to differentiate it from mains supply. Information on installing a system can be found with organizations like or

Bunding: Any fuel stores such as diesel or oil must be protected by adequate bunding to prevent fuel leaking into local water courses.
