Sustainable Drainage
The Environment Agency in the UK advocates Sustainable Drainage
schemes, because they do not contribute to flooding, they
encourage wildlife and provide visually attractive, and educational,
amenities in the form of wetland habitat which is increasingly under
threat in the UK. Sustainable Drainage is a new environmentally
friendly way of dealing with surface water runoff which avoids the
problems associated with conventional drainage practice.
Conventional drainage exacerbates flooding, causes pollution and
is generally more expensive to install and to maintain than
Sustainable Drainage schemes.
The Problem on our hands:
With ever increasing numbers of vehicles and machines being used
by society, we see more pollutants being released into the
environment. With impermeable surfaces,these pollutants are
typically carried by run-off water into our sewers and natural
watercourses, where they can cause significant and costly damage
to treatment plants,or devastate the fauna and flora of
our ditches, streams and rivers.
The Cotterill Civils Solution:
One solution to this environmental issue is Permeable Paving.
Infiltration - surface water is directed via voids within areas of solid paving.
Porous - water is drained directly through the surface

Another Cotterill Civils solution to excess run-off is Wetlands.
We can construct and install wetland designs to meet the needs
and wants of The Environment Agency.
Wetlands are necessary to control environmental factors such as:
Erosion control. Wetland vegetation reduces erosion along lakes
and stream banks by reducing forces associated with wave action.
Flood control. Wetlands can slow runoff water, minimizing the
frequency streams and rivers reach catastrophic flood levels.
Balancing ponds
A balancing pond is a simple but innovative solution to excess run
off, when a large surface area is concealed from natural drainage.
At Cotterill Civils we can provide a solution necessary for the area
concerned.
