Stormwater Management
At Birkenhead, we have a comprehensive management programme in place to recycle stormwater on site, reducing our use of mains water. This includes having six main catchment areas strategically placed around the site to maximise the volume of stormwater we recycle.
Water recycling
As well as stormwater, we capture water run-off from our truck
washes that is also recycled on site.
Water that contains traces of silt is typically treated through
sedimentation, catchment and filtration systems, including surface
and underground sumps, settling ponds and reeds that improve the
water quality.
Treated
and captured water is then used to irrigate gardens around the site
or recycled into our wetlands/stormwater catchment areas, including
Schroder
Park and our southern wetland areas.
The wetlands provide an excellent habitat for a wide range of
native flora and fauna. Schroder Park is also a popular place for
the community and local schools to come and visit.
The continuous supply of quality recycled water to our wetlands
and gardens ensures the healthy ecosystem is maintained all year
round, allowing plants and wildlife to flourish.
Future Plans
A comprehensive study is currently underway to help us identify
and further enhance our stormwater management and water recycling
at Birkenhead.
There are also plans to relocate our southern stockpiles, which
would reduce the suspended soils loads in the area and result in
improved quality of stormwater runoffs.
We are committed to continually finding ways to conserve water at
Birkenhead and have a Water Efficiency Team dedicated
to identifying improvements.
