Recycled water in Council House 2
Council House 2 (CH2) is an office building for council staff that was designed with sustainability as a central theme.
Completed in 2006, the building includes a range of features and technology that conserve energy and water, while also improving the working environment for staff.
The overall water conservation design strategy for CH2, including water saving impacts of the cooling and ventilation systems, has established a total water consumption design performance target of just under 31 litres per day per person. Water management measures implemented by CH2 fall primarily into four categories:
- water efficiency
- water recycling by sewer mining
- water reuse (rainwater harvesting and fire sprinkler test water)
- innovative water saving techniques.
CH2 has the following features:
- ‘AAAA’ fittings and fixtures throughout the building
- taps and showerheads of low water flow rate of approximately 2.5 litres per minute and nine litres per minute respectively
- water flow to all hand basin taps controlled by electronic sensors
- 4L/3L dual flush toilets and two litre flush urinals.
