Description

Re-Build (including draining and silt removal) of Grove Lake Duck Pond - Specifically, the repair of the walkways (root damage), the walls of the lake where brickwork is failing, the removal of silt from the lake (approx cubic 290m), delivery of SILT trap for two x inlets.
Detailed work as follows:
Work Schedule: - Silt Removal:
Silt in Pond - approx. 290 cube
• Cofferdams to be set up splitting the pond into 3 or 4 areas
• Inlets and outlet to be diverted where required
• Silt allowed to drain and then removed from Pond
• Silt to be stored and dried next to pond then taken away from site
• Disposal of silt as recommended by local authority (The Council may have a location to remove the silt too, via a local farmer and the Council's allotments, but this is not guaranteed).
Work Schedule - Walkway:
• The concrete walkway above the brick walls is no longer even, and provides a trip hazard for walkers. It has been repaired with Tarmac in order to get the differing levels to "meet", but now requires re-setting to ensure an even walkway around the entire pond.
Work Schedule - Wall Damage:
• As the damage to the walls is only visual above the water line a further inspection would be required when each section is drained
• All existing brickwork to be jet washed for closer inspection
• Any failing brickwork to be replaced
• Any lose mortar to be replaced between brickwork
• The movement in the walls will make future guarantees limited on any works undertaken
Note: The pond is not leaking, and the base of the pond is estimated to be a proportion of cement, and a proportion of clay (the surrounding area is made up of London Clay)
Work Schedule - Island:
• An inspection is required below water line of the brickwork
• Some copings to be re-laid or replaced as necessary
Work Schedule - Introduction of Aquatic Planting:
• It would be possible to introduce some planting zones, but these would be required to be separated from the fish
• Shallow marginals or floating planters could be introduced
• Plants provide a balanced aquatic eco-system and would help keep the phosphate levels lower
Work Schedule: Inlets and outlets
• The outlet could be modified to allow for greater collection of silt and floating debris, this could help alleviate any future flooding of the road
• The inlet from the feeder SuDS pond requires a silt trap, as currently it appears as an open pipe
