Water conservation

Rain water tanks

Water conservation has become an increasingly important issue over the last few years.  Further expansion of development within Blacktown City will place pressure on our water supply and will require all residents, as well as Council, to reduce water use.   

Blacktown City currently has about 370,000 people. This is expected to grow to more than 500,000 people by 2036. This equates to at least 65,000 new residential dwellings in both the North West Growth Area and within the existing residential areas.

The growth in population, dwellings and infrastructure will increase:

  • demand for drinking water

  • stormwater runoff flowing off roads and buildings and into our creeks

  • the need for water sensitive urban design (WSUD) assets that reduce flooding and also pollutant loads to Blacktown City’s waterways

  • demand for high quality public open space

  • local temperatures through the urban heat island effect.

Currently the combined water required for all residents, businesses and council services in Blacktown City is 32.8 billion litres of drinking water a year. The expected population growth will result in the consumption of an extra 11.2 billion litres of water a year to meet residential, industrial and commercial demands.
