A comprehensive pond restoration and enhancement project was recently undertaken at Woking Park, the scheme has involved re-excavation of a completely overgrown pond and substantial improvements to an existing badly eroded duck pond, in aid of creating a natural environment for the local wildlife and a scenic retreat for the local residents.
Over 300 tonnes of sediments were removed from the ponds and re-modelled on site, 170 metres of a specially engineered clay lined trench was installed to aid water retention and over 1600 grasses, shrubs, ferns and aquatic plants were introduced to improve the amenity interest and biodiversity value of this part of the Park.
The scheme has also included the construction of a water cascade, artificial stream, viewing area, timber decking and a rain water harvesting system which will collect rainwater from the roof of the swimming pool in order to provide top-up water during the drier summer months.
Dyer & Butler Ltd & Upton McGougan Ltd were short listed for Sustainable Designer of the Year by Building Magazine due to this scheme which involved a number of innovative and sustainable solutions.
Scope
[edit]The project involved the restoration of two ponds plus the creation of a third pool and a water cascade, spillway, water-retaining diaphragm wall, water feature, footbridges, bridges, decking, viewing platforms and seating.
Content
[edit]The scheme involved clearing the heavily silted ponds and overgrown vegetation on the banks. Over 300 tonnes of sediment was re-used to re-contour the area and help grow a new lawn.
As part of the restoration 170m of specially engineered, clay lined trench was installed. This helps to retain the water in the ponds and bring the water up to original levels.
The water cascade has 10 cubic metres of water flowing over it per hour which refreshes the air and improves the water quality by increasing the oxygen content. The cascade and the ponds are topped up using rainwater collected from the roof of the adjacent swimming pool which is stored in a high-tech underground tank.
The viewing areas are designed to entice visitors and educational groups who are keen to find out more about local wildlife.
Achievements and benefits
[edit]Awarded runner-up for Sustainable Designer of the Year 2005 by Building Magazine due to this scheme.
Wildlife, including nesting birds and frog spawn, has moved back to the area and over 2500 grasses, shrubs, ferns and aquatic plants were planted.
