  4. 4. Water... <ul><li>Water usage in the UK has been rising by 1% a year since 1930 </li></ul><ul><li>Each Briton uses about 150 litres per day, however the embedded water consumption per person is over 3400 litres every day! </li></ul><ul><li>London is drier than Istanbul, South East England has less water than the Sudan or Syria. </li></ul><ul><li>1.2 billion litres of water are flushed needlessly away every day in the UK. </li></ul><ul><li>Source : Waterwise </li></ul>
  5. 5. Commercial washrooms.... <ul><li>Over half of ‘domestic’ water used in commercial premises can be due to urinals operating without flush controls. </li></ul><ul><li>Source : Envirowise Water management leaflet </li></ul><ul><li>In the absence of urinals, WC’s can account for up to 75% of ‘domestic’ water used in commercial premises. </li></ul><ul><li>Source : Envirowise Water management leaflet </li></ul><ul><li>Today’s 6/4 flush WCs can give an average flush of 4.5 litres – half the volume used in the 1960’s. </li></ul><ul><li>Source : BMA </li></ul><ul><li>In commercial premises around 25% of ‘domestic’ water is used when operating taps. </li></ul><ul><li>Source : Envirowise Water management leaflet </li></ul>Flush capacity of WCs since 1950s
  6. 6. Water Regulations <ul><li>Urinals </li></ul><ul><ul><li>No more than 7.5 litres per bowl per hour (10 litres for a single bowl) and should have a device fitted to prevent flushing when the building is unoccupied. </li></ul></ul><ul><li>WCs </li></ul><ul><ul><li>A single flush of 6 litres maximum, or a dual flush of 6 litres maximum and a reduced flush of no more than two thirds of the maximum flush. </li></ul></ul><ul><li>Taps </li></ul><ul><ul><li>The maximum flow rate should be no more than 3.6 litres per minute in a sink without a waste plug. </li></ul></ul>Sources : Water Regulations, Environment Agency, BMA

  9. 9. Urinal Cistern Controls Range <ul><li>Hydraulic Valve </li></ul><ul><li>Infrared Valve (IRC) </li></ul><ul><li>Operates based on washroom occupancy. </li></ul><ul><li>Infrared sensor detects activity in the washroom and opens water supply to urinal cistern. </li></ul><ul><li>In non-domestic premises, water is only being used during working hours. </li></ul><ul><li>Operates based on washroom usage. </li></ul><ul><li>Water supply to urinal cistern is closed until another appliance is used. </li></ul><ul><li>In non-domestic premises therefore, water is only being used during working hours. </li></ul>
  10. 10. Urinal Cistern Controls – Hydraulic Valves <ul><li>The number of flushes per hour are not controlled by the Cistermiser hydraulic valve; </li></ul><ul><li>It is therefore not possible to accurately calculate the water savings; </li></ul><ul><li>However, we recommend that the flow adjuster on the valve is used to match the flow to the daily usage of the washrooms; </li></ul><ul><li>Water usage can be reduced by x through accurate adjustment. </li></ul>
  11. 11. <ul><li>The number of flushes per hour is controlled by setting the flow rate through the IRC Solenoid Valve </li></ul><ul><li>Detection of a person triggers a 30-minute cycle </li></ul><ul><ul><li>Valve opens and passes water to the cistern for 30 minutes </li></ul></ul><ul><ul><li>Sensor switches off while valve is open </li></ul></ul><ul><ul><li>Optimum water flow rate = sufficient to fill cistern and flush once per 30 minute cycle </li></ul></ul><ul><li>Water consumption and savings can be calculated </li></ul><ul><ul><li>Assume 2 flushes per hour during working hours (worst case) </li></ul></ul><ul><ul><li>Calculated savings are therefore lowest case </li></ul></ul>Urinal Cistern Controls – IRC Valve

  14. 14. <ul><li>Reverse the trend... </li></ul>Urinals often flush regardless of use, wasting a lot of water, especially out of hours. Installing a Cistermiser IRC valve can save typically 129,600 litres of water per urinal bowl per year and reduce metered costs by an average of £302.51 per urinal bowl. Urinal Cistern Controls - IRC
  15. 15. <ul><li>Total water cost savings per year have been calculated per urinal bowl installed. However 2 or 3 urinal bowls may be installed per cistern and only one IRC is required per cistern.
