COOLING TOWERS
Cooling towers are a component of some buildings' cooling systems. Where installed, cooling towers can account for up to 31% of the total water used in an average building; a statistic that is even higher in summer (DEH, 2006a). In shopping centres, this figure can be as high as 60% (DNRMW, 2006).
‘Water is used in cooling towers by evaporation (which provides cooling), bleed (to prevent build-up of dissolved and suspended solids), drift (water droplets entrained in exhaust air), splashes, overflow, and leaks' (DEH, 2006a). |

It takes approximately 15 minutes to deliver just one liter of water to the soil with drip irrigation, compared to five seconds when hand watering?
Most plants will flourish on a 25 - 30 min dripper watering twice a week.
Installing a Moisture sensor can save up to 50% of your required irrigation water needs. |
