Water Resources Strategy: 

Water Resources Strategy Strategic review of water resources for Melbourne until 2050 Purpose is to ensure: a safe and reliable supply environmentally sustainable acceptable cost community involvement

Water Resources Strategy: 

Water Resources Strategy Population growth 1.2 M (32%) to 2050 Household growth of 56%to 2050 Limited opportunities for new water sources Alternative supply options not financially viable except for large greenfields developments

Government Objectives Looking to: reduce water use in Melbourne by 15% by 2010 Increase water recycling in Melbourne to 20% by 2010 Water Resources Strategy information on www.watersmart.vic.gov.au

Slide24: 

Each year, a typical Melbourne home uses about 240,000 litres of water or about one quarter of an Olympic-sized swimming pool. Melbourne’s average daily water consumption is about 1,315 million litres! How Much Water Do We Use?

Water Conservation Tips: 

Water Conservation Tips

Slide28: 

General Water Saving Tips take shorter showers buy ‘AAA’ or better products use a trigger nozzle update with dual-flush toilets only wash with a full load in the dishwasher & washing machine

Slide29: 

Water Saving Tips - Outdoors Check the four day weather forecast before watering your garden - let the rain do the watering Water your garden less often - but more thoroughly to encourage deeper plant roots Turn off your automatic sprinkler systems when it rains, and for a couple of days afterwards Sweep your paths and driveways, don’t hose them Spread mulch at least 75mm deep on your garden

Slide30: 

Water Saving Tips - Indoors Install a water efficient shower head (AAA rated) (9 l/min vs 22 l/min) Update your single flush toilet to a modern dual flush can save 35,000 litres a year Repair leaking taps and turn off dripping taps Install aerators on existing tap nozzles use washing machines and dishwashers only for full loads

Slide31: 

Install a Rainwater Tank No longer need a permit to install a tank. You may need one if you wish to have your tank on a stand. Check with your local council to clarify Typically over 120,000 litres of rainwater run-off per household goes down the stormwater drain each year. Tanks help to capture some of this resource If just 1% of YVW’s customers installed a 600 litre tank, over 3500 megalitres could be saved each year

Slide32: 

Greywater Diversion Greywater is household waste water from bathtubs, showers, basins, & washing machines. It is NOT water from toilets Installing a greywater system can be as simple as temporarily using a bucket to collect the washing machine rinse water for the garden There is no objection to the temporary diversion of greywater provided that adequate care with soaps etc are taken

Slide33: 

Greywater Diversion Permanent diversion of greywater for reuse requires approval from relevant authorities such as EPA, Local Councils & YVW All plumbing works on temporary and permanent systems must be carried out by a qualified plumber in accordance with the relevant plumbing codes and standards
