Department advises self suppliers to prepare for wet season
Released 23 May 2011
Department of Water dry season response director Greg Davis said self-suppliers would benefit from ensuring water storage infrastructure and water storage catchments were well-prepared to receive the predicted rainfall.
"Self-suppliers in the south west need to make sure they clean the silt out of their dams and tanks while they still have access," he said.
"Silt washed into dams reduces the reliability of water catchments and cuts down storage volume. Silt also reduces dam depth thus increasing the volume of water lost to evaporation."
Mr Davis said self-suppliers should also check gutters and other rainfall harvesting fixtures to ensure they are functional and able to maximise any rainfall, and contemplate putting in extra rainwater tanks or increasing roof catchment space to improve water harvesting.
"By improving water harvesting and catchment on-site for both domestic and livestock use, we can ensure that we make the most of the rainfall that we receive over the winter months," he said.
Mr Davis added changes in rainfall patterns in 2010 resulted in low rainfall run-off into water tanks, catchments and reduced groundwater recharge in the south west of the state.
"Users who rely on streams for stock and domestic water need to be aware that streamflow in many areas has been significantly reduced and make provision for other water sources," he said.
Self-suppliers need to consider:
- Removing silt from traps and inlets to dam
- General maintenance of piped outlets and spillways
- Checking sealing of wall for cracks
- Installing extra rainwater storage
For additional advice on the steps to take, self-suppliers can contact your department of water regional office. * Note: A self-supplier is a person not served by the scheme water system who obtains their water supply from rainwater tanks, bores or dams.
