Drainage

In certain ground situations water or gas can become trapped under the liner, for example; if the lagoon is built on clay, the soil contains organic matter that could generate methane gas, or if there is a high / fluctuating water table.

Drainage pipes in situ

Over a period of time, any of these conditions may cause damage to the lagoon liner, but they can be prevented by installing a drainage system of porous pipes laid in a sand bed or other permeable layer.

Drainage Pipe Layout

It is highly recommended that the ground conditions are checked at an early stage and, if appropriate, a drainage pipe system should be included in the lagoon design. Where necessary, you should seek expert advice, or contact us for more information.
