Slurry storage & Silage clamps

Slurry or effluent storage

We are able to quickly & cheaply submit planning applications for slurry stores / towers and slurry lagoons through out the UK including building warrant if in Scotland.

Fill out the Contact Us form with the store details (type & size) and location for a detailed quote outlining our services and costs. 

If you are going to be or have already submitted a slurry storage grant for the AECS Slurry Storage in 2023 or AECS Slurry Storage in 2024 please get in touch and we can sort out all the paperwork required for Planning, Building warrant and SEPA.

There are a few different ways to construct a slurry store or lagoon.

Cast in-situ concrete slurry tank these can be any shape above or below ground.

Pre-cast concrete slurry tank these are typically rectangular below ground or circular above ground.

Slurry tower a metal tank in a few different material and coatings, these are normally above ground and can't be backfilled.

Slurry lagoon lined with clay or a man made impermeable liner material like EPDM, PVC & HDPE.

If you are planning to build new slurry storage or an effluent tank here are some points to note; Below relate to Scotland.

Full planning is required if the slurry storage or effluent tank is over 1000 sq metres (10763.9sq feet).

If below 1000 sq metres (10763.9sq feet) a prior notifications will normally be required. Unless the slurry storage is within 400 m (437 yards) of a protected building, ie. building occupied by people but not part of a working farm" see planning guidelines.

If in Scotland then building warrant is required for all slurry and effluent storage

All slurry stores require an engineer to certify the design.

The need to make provision for not less than 750 millimetres of freeboard in the case of a tank with walls made of earth and 300 millimetres of freeboard in all other cases.

All new / substantially enlarged / reconstructed slurry stores require to comply with the Water Environment (Controlled Activities) (Scotland) Amendment Regulations 2021 which amalgamated the requirements of the SSAFO which are now revoked into CAR. These are now GBR 32-The storage of slurry. In addition, GBR 34 was introduced to control the storage of liquid digestate where not already covered by regulations.

This requires you to notify SEPA 30 days before intended first use.

The SEPA notification form has to be signed by an engineer stating he is satisfied with the design and construction of the works.

Site the slurry storage at least 10 m from any water course including field drains or ditches into which slurry could enter if it were to escape.

You must construct new or substantially reconstructed or enlarged stores to last for at least 20 years with proper maintenance.

You must not store slurry:

within 10 metres of surface water or wetland

within 50 metres of any spring or borehole.

Agri Design can assist with all of the above requirements. We provide a reliable, independent service from initial discussions through to first use. 

Silage clamps

If you are planning to build a new silage clamp be it for a small farm or a large anaerobic digestion (AD) plant here are some points to note:
