Conservation technologies

Here are some examples of common conservation technologies that can be installed to save water and operating costs.

Kitchen
FaucetFaucet aerator
DishwasherWater efficient models; automatic shut off
Garbage disposalGarbage strainer
Bathroom
FaucetFaucet aerator; automatic shut-off; infrared faucet; self-closing faucet
ToiletUltra low flush toilets (3L and 6L)
UrinalUltra low flush and "waterless" urinals
ShowerLow flow showerhead
Laundry
Washing machineHorizontal axis washing machine; continuous batch washer; rinse water reclamation; wash water reclamation; computer automated control system
Sanitation
Facility cleaningDry extraction carpet cleaning system; automatic shut-off valves; pressure-reducing valves
Sterilizer/autoclaveFlow-metering; control valves; air pressure host
Equipment washingWastewater Reclamation
Irrigation
SprayingMoisture sensors and timers; rainfall sensors
PlantingLow water use plants and shrubs; replace lawn
Recirculating cooling
Cooling towerConductivity control, maintenance of make-up valves; recycling; add acid to reduce carbonate scale
Evaporative coolerRecirculating pumps; eliminate excessive bleed-off
BoilerEliminate excessive blowdown; eliminate mixing valve water; ion exchange
Once-Thru cooling
Air conditionerAir-cooled equipment; reduce flow rate
Air compressorConnect to recirculating cooling system
Vacuum pumpConvert to mechanical vacuum pump
End useConservation technology
