Dairy farms must be capable of storing large quantities of slurry in order to meet the restrictions on spreading slurry on land in winter or wet periods.
A typical example is a farm in the Vale of Belvoir, whose 500 cows and 100 followers created a need to store over 10,000 m3 (2.23 million gallons) of slurry. A lagoon to hold 13,600 m3 (3 million gallons) was designed using the heavy clay soils of the site to ensure the lagoon was "leak proof". A drainage scheme was incorporated to ensure no extraneous rainwater ran into the lagoon from higher ground and a nearby cattle walkway as rainwater would compound the storage problem.
The Landyke advice and design service was a crucial part of gaining planning permission and Environment Agency approval for the project.
