The model home for water-wise living has been set up by Dubbo Regional Council and will be open to the public on Saturday.

The council's director of infrastructure Julian Geddes says the Blue House offers the community water-saving advice and highlights water-efficient appliances, devices and fittings.

Inside the Blue House are appliances such as a front-loading washing machine which uses less than half the water of an equivalent top-loading machine.

Outside, hardy plants in garden beds draw water from a reservoir as needed, saving up to 90 per cent of water normally used.

Under the lawn is a drip system that monitors the soil moisture and releases small amounts of water when required.

Mr Gedddes said all the devices were readily available from hardware and plumbing stores and most of them could be retrofitted to existing houses at a low cost.

"Others are a great option to consider when building a house as they can be easily installed during construction and will lead to long-term savings," he said.

Mr Geddes said the water-saving devices on display in the Blue House had been donated by companies which had embraced the project.

He said they had been fitted and installed by council staff.

The Blue House is at 20 William Farrer Drive, a property owned by the council.

It opens on Tuesdays between 12pm and 2pm, and on the first Saturday of the month between 9am and 12pm.
