LAND DRAINAGE Land drainage is principally used to alleviate water logging in fields and gardens, but it can also desiccate certain ground types in prolonged dry spells Land drainage works by providing an open conduit for groundwater to follow to a disposal point, or, in the case of dispersal drains, to a dispersal area or leach field. There are a few variations on this theme, involving the type of backfill material, and the type of pre-formed conduit that is used, but all rely on two simple principles; that the land drain provides a 'path of least resistance' for groundwater to follow, and that, left to its own devices, water flows down even the gentlest of slopes. |  |
