Water and Sewerage
A reticulation network of water mains carries treated water from Goldenfields Water County Council rising mains to the various service reservoirs located at Harden, Demondrille, Jugiong and Galong and then onto consumers within the shire.
This network consists of over 143 km of water main with diameters ranging from 100mm to 300mm. The water mains are made from a variety of materials including concrete, asbestos cement, cast iron, ductile iron, uPVC and polyethylene.
There are regular water samples drawn from various points within the reticulation system to monitor water quality.
A program of flushing dead ends and water mains cleaning and reservoir inspections have been implemented to ensure water quality within the system meets the appropriate guidelines.
Sewage is collected and transferred to the Waste Water Treatment Plant via a gravity reticulation network about Harden Murrumburrah.

The network consists of approximately 35km of sewer main ranging from 150mm to 350mm diameter. Construction of the gravity network began in 1936, with much of the original pipework still in service. Some of the earlier pipes are in reasonable condition, this being known from recent closed circuit TV surveys of the whole network completed. A variety of materials have been used in construction of the network including concrete and uPVC.
During wet weather significantly increased flows are experienced at the Waste Water Treatment Plant. This can be attributed to the poor condition of some existing pipes, which are subject to infiltration from the surrounding ground during prolonged rainfall. Council continues an replacement program using trenchless techniques including relining. This program is ongoing to help maintain and improve the sewer reticulation network service provided.

Saving Water in the Garden
By following a few simple tips and using alternative water sources, you can still maintain your garden during the drought.
When planting, dig plants into the ground leaving a trench of about 50mm around the base of the plant to make sure water funnels down to the roots. You should also consider: Buying plants that are drought tolerant and suited to our local climate so your garden will require less watering. Look out for plants at your local nursery that carry labels such as Water MiserTM.
Condition your soil by adding a soil wetting agent or water saving crystals.
Group plants with similar watering needs to ensure drought tolerant plants are not over-watered.
Keeping your lawn alive
Most lawns will tolerate a period of dying-back (browning) during a drought or dry season and will return to health when normal rain patterns return.
The higher you mow the grass, the deeper and more extensive the roots. This will make your grass more drought tolerant and it will require less watering.
Don't mow if hot weather is expected, or cut the grass shorter than 25mm, as the grass needs enough leaf area to protect itself from the burning effects of the sun.
With many traditional plants or lawn types not suited to the Aussie climate, drought tolerant species make great sense, as they need less watering and quickly adapt to drier conditions.
Saving Water Inside the House
Tips on reducing water usage throughout the house.
In the Bathroom:
Install a water efficient shower head
Install a dual flush toilet or cistern weight in your old single flush toilet they can halve the water use from 12-20 litres a flush to six (6) litres a flush.
Install aerators or flow regulators on your taps often it is the pressure rather than the water volume that you need.
Fix leaking showerheads and taps. A dripping tap can waste more than 35,000 litres of water a year.
Fix leaking toilets: leaking toilets can waste around 20-40 litres of water an hour.
Insulate hot water pipes: this avoids wasting water and power while waiting for hot water to flow through.
Make sure your hot water thermostat is not set too high: adding cold water to cool the temperature of water is wasteful.
Take shorter showers: long hot showers use around 10 to 20 litres a minute, so cutting a 10 minute shower down to four (4) minutes will save around
60 - 120 litres of water.
Don't leave water running when brushing teeth, washing hands or shaving.
Use a bucket to catch grey water in your shower or bathtub to be reused in your garden.
In the Kitchen:
Only run the dishwasher when you have a full load, as they can use up to 60 litres of water for each load.
Don't leave water running when rinsing dishes, washing vegetables or washing hands.
In the Laundry:
Install a water efficient washing machine: front loaders are often more efficient than top loaders.
Make sure the washing machine settings are right for the load before you begin: if there is no load adjustment setting, wait until you have a full load.
