Summary<br />
Green space enhancement and<br />
re-purpos<strong>in</strong>g for surface water<br />
<strong>in</strong>terception and <strong>in</strong>filtration.<br />
Project description<br />
Next to Priory Road is a l<strong>in</strong>ear green space<br />
with mature plane trees planted along<br />
the roadside. The verge is about 75m long<br />
and was highlighted as a site to deal with<br />
surface runoff from the road, via a sewer<br />
connection directly to the River Moselle.<br />
This project is part of a suite of <strong>SuDS</strong><br />
schemes locally that will cumulatively<br />
improve water quality.<br />
Objectives<br />
• Intercept road runoff pollutants<br />
at source and use the exist<strong>in</strong>g<br />
landscape to allow ‘<strong>in</strong>terception<br />
loss’ (ie, prevent water from reach<strong>in</strong>g<br />
the ground) for everyday ra<strong>in</strong>fall<br />
• Clean and cool runoff dur<strong>in</strong>g<br />
summer when the watercourse is<br />
most susceptible to the effects of<br />
pollution and water temperature<br />
<strong>in</strong>creases (which <strong>in</strong>hibit the ability of<br />
water to carry dissolved oxygen)<br />
