The construction of a new water feature normally starts with a walk over the site with the Client to discuss the possibilities available. We can then provide a written budget price identifying the main areas of work and order of costs.
Next, the process may include a topographic survey of the site to produce a site plan, development of drawings to show the lake and specific construction details. A hydraulic model may need to be considered to calculate the maximum amount of flow that will enter the lake if it floods; this information is required to size the overflow structures.
The budget price is reviewed to give a firm quotation as plans become finalised and the scope of works agreed.
Permission for lake construction may be required from the local planning authority (change of use of the land), unless it is in a garden, and Flood Defence Consent may also be needed from the Environment Agency (EA). Environmental Impact Assessments and Flood Risk Assessments may have to be carried out, and copies of drawings and construction method statements supplied to planners and the EA.
When approval has been given, lake construction work can start, with stripping the site of top-soil, carrying out the earthworks, building the water control structures, installing bridges, decks, jetties or boat-houses, and then moving on to final trimming, shaping and topsoiling.
The lake is allowed to fill as the area is landscaped, aquatic planting carried out and fish introduced.
Kingcombe Aquacare can carry out all, or any part, of the process outlined above, including applying for consents and permissions, design, construction, planting and stocking with fish.
Lakes may be constructed either “in the ground” or behind a dam or embankment. If a dam retains more than 25,000m³ of water then it is subject to the legislation of the Reservoirs Act, which places duties on the owner of periodic inspection and maintenance. As a result of some the extreme summer rainfall over the past few years, the EA intends to reduce the impoundment volume threshold to 10,000m³.
