Liverpool Council has said it will be cracking down on poor sediment control through a tougher, month-long campaign at building sites.
The council explained it monitors sites continuously but has notified all construction sites in the Liverpool precinct that on May 16 there will be checks by the council officers.
Much of the focus is expected to take place in new housing estates.
Liverpool Mayor Wendy Waller said the compliance and education campaign, Get the Site Right, aims to improve the quality of waterways to make them more attractive to wildlife and to swimmers.
“Our council fully supports the joint effort of the NSW Environment Protection Agency and about 20 other councils to cut sediment-laden run-off from building sites,” she said.
“Up to four tonnes of soil can be washed from a building site during extreme rain.
“When run-off washes into stormwater drains and hits our waterways, it cuts water quality, smothers aquatic vegetation, clogs fish gills and can block watercourses during storms and floods.
“To date in 2017 to 2018, 60 fines were issued, costing builders $191,000.
“While Get the Site Right is a targeted blitz – and fines will be issued – prevention is the cure. Developers and builders should have it as a basic part of their site management plans that no sediment will leave their sites because they have effective erosion controls.”
