FP McCann’s slurry stores are made from high quality prestressed concrete panels, designed in accordance with BS 5502.

The slurry would normally be pushed over a retaining wall using a tractor or automatic scraper. However, if appropriate, a ramp, weir, underground pipe, mechanical loading system or pump may be utilised instead. When emptying the store, it can be pumped or removed by a vacuum tanker. Solids can be removed by a tractor bucket via a ramp. Our ramp panels are ideal for ease of construction and minimal loss of capacity within the store.

A properly designed strainer box would allow dewatering of the store to increase the capacity of solids. The remaining muck can either be handled as a semi-solid or a slurry if sufficient liquid is retained to allow agitation. The management of the store during the winter is of prime importance to ensure that this simple system works efficiently. Strainer box or weeping wall panels with slots are designed to give maximum separation and to minimise jetting, allowing the liquid to transfer via a perimeter gully to a holding/settlement tank. Separation of the liquids and solids can make handling easier and is particularly useful if low volume irrigation through the winter period is permissible.
