Slurry & Waste Tank Design, Installation, Repair and Maintenance Services
We provide a comprehensive range of slurry and waste handling installations including tanks, pumps, pipework and waste water or slurry conditioning systems to customers throughout Derbyshire, the Midlands and the rest of the UK.
Health & Safety
Due to recent tragic circumstances, everybody is now more aware of the danger from entering a slurry store. Rockall Safety are able to hire gas monitors on a "next day" basis, at reasonable rates.
Supply & Installation
Predominantly supporting the agricultural sector, we also install tanks for waste and anaerobic digestion. We carry out a full site survey, and supply drawings suitable for your planning applications, or even complete the application for you.
We supply Storth Tanks which in our experience are of a quality as good as or better than other tank manufacturers
Tank Modifications, Repairs & Disposal
We also refurbish and repair existing older tanks including Boythorpe, Gascoigne, Alfa Laval Harvestore, AO Smith and Simplex, either in situ, or to re-erect on another site.
We only purchase good quality second-hand tanks for reconditioning and resale if we are sure that they will have a life of 20 years, to comply with EA regulations. Some tanks were originally installed with the intention of extending them at a later date. We can decide whether your tank is such, and supply new or good second-hand sheets to do so, either adding a ring to the top, or inserting a ring at the bottom if you require additional capacity.
In line with the requirements of your Insurance policy and the Environment Agency, we will provide a full inspection of slurry and waste tanks followed by a detailed report.
Conditioning & Treatment
Slurry conditioning is becoming increasingly important to preserve the fertiliser value and control odour. We recommend Ameram equipment to do this most effectively, and install Aeromixers in new and existing circular above ground stores, and slatted cellars. Biocrust is a new development in floating covers to control odour escaping from the slurry and lock in nitrogen to maintain fertiliser value. We now work closely with a supplier of treatment equipment, ranging from a simple rag filter, through settlement tanks, different types of separator, lamella plate clarifiers, and aeration systems to complete sewage treatment plant ready for discharge to a water course.
We often are asked about fitting covers to existing tanks. This older DEFRA document is particularly informative
If your main concern is keeping rain water out of the slurry store to maximise available storage, a floating cover is probably the best solution. Please remember that all other types of cover require a stronger tank and foundation to carry the increased wind loading. Most covers have a life expectancy of around fifteen years, much less than the twenty plus of the tank itself.
Covers are supplied by SteFos who have over 30 years experience supplying covering solutions in agriculture, industry and horticulture inside and outside of Europe.
