Stormwater
-
Attenuation

The addition of impermeable surfaces will lead to an increase in the quantity of surface water runoff, which can overload the drainage system / downstream watercourse and lead to potential flooding.
-
Flow Control

Before society added so many roads, parking lots and buildings, roughly 80 percent of the rain that fell in a natural catchment would typically soak into the ground where it would be filtered and cleansed before gradually recharging our aquifers.
-
Infiltration

Infiltration is a priority process for Sustainable Drainage Systems (SuDS) to ensure control of water as close as possible to the point of falling and mimic natural processes.
-
Rainwater Harvesting

With increasing population combined with climate change bringing less rainfall per year, the stress on potable water will continue to increase.
-
Stormwater Treatment

Stormwater runoff can convey pollution from a wide variety of sources. This pollution can be mobilised during storm conditions, adversely affecting water quality and wildlife habitat in receiving waters.
