We have extensive experience of all aspects of land drainage and flood prevention works, working regularly for sports clubs and Local Authorities in parks, schools, and playing fields.
Land drainage systems fail for a variety of reasons. Land Drainage is rarely maintained. Over the years it will silt up until it is no longer effective, resulting in waterlogged ground or significant runoff onto paved areas where it can be a problem (especially in freezing weather).
Traditionally, land drains were constructed without access points for maintenance, with often no indication of where land drains are or even whether they exist. Where land drainage systems silt up over a long period (and their capacity to drain an area gradually decreases), we would expect you to notice a gradual worsening of the problem. In other cases, tree roots or a localised collapse can block a land drain. When tree roots have found a way into a land drain, and therefore a rich source of moisture, they can grow very quickly. In cases where a problem appears over a relatively short period, tree roots are often the culprit.
Occasionally, a land drainage problem appears due to upstream property development, or possibly maintenance of a land drainage system further upstream. As a result of this, more water enters your silted or root infested land drain. Similarly, if you resolve your problem, it is likely that neighbours downstream may subsequently experience problems. Please feel free to pass on our details.
EDS can locate land drains, jetting, root-cutting or replacing as necessary to return your asset to its original condition. By equipping an excavation unit with drain CCTV and sonar tracing equipment, we can often bring a systems back to effective working order by investigating and repairing during the same visit. In cases where the issues are localised, this approach can often save time and expense for the client.
Where no land drainage exists, we can provide an investigation, design, and installation service. In cases where no outfall for land drainage exists, and if your ground conditions are suitable, we may recommend a discharge of the surface water or land drainage to a soakaway. Beware! We are contacted regularly by clients who have incurred significant expense paying for a soakaway to be installed in areas where the ground conditions are totally unsuitable (for example in clay). The Building Regulations and CIRIA provide guidance on percolation tests and in order to avoid expenditure on ineffective solutions, we would almost always recommend that a percolation test be undertaken prior to design and installation of a new land drainage system, to establish suitability and required size.
During construction we will save turf wherever possible. We will use boards for storing excavated material and we will attempt to replace any displaced plants. We will always endeavour to return your asset to as close as possible to its original condition.
In addition, EDS can assist with all aspects of watercourse maintenance and also provide guidance on legal aspects of culverting watercourses together with a complete design and install service.
