We design, supply and install a range of lagoons using specialised materials depending upon your requirement.


Stormwater Attenuation Lagoons

Stormwater attenuation lagoons are seen as a best-practice method of controlling the flow of stormwater runoff. They are designed to prevent flooding by controlling the amount of stormwater that is released into the environment at any given time. When a storm event occurs, the lagoons fill up and store large volumes of rainwater temporarily, which is then gradually released.


Water Storage Lagoons

A water storage lagoon is also known as a farm pond or water storage pond. It provides farmers with a cost-effective way to store large volumes of water for purposes such as the irrigation of crops or to feed their cattle. The ponds can also be used for a variety of other purposes, including irrigation of crops, water to feed animals, aquaculture, recreation purposes etc.


Slurry Storage Lagoons

Lagoon liners provide a cost-effective and compliant means to contain agricultural waste on farms. Slurry is a fantastic resource for farmers. Made from a mixture of manure and water, it’s a natural and nutritious fertiliser that helps grass and other crops to thrive. Its storage is governed by various legislation, such as the SSAFO regulations and OSR Wales.
