Prefabricated slurry tank – a complete solution for farms

The manure tank is a key component of the infrastructure of any modern livestock farm, providing safe storage of manure for a minimum period of 6 months, as required by law. Prefabricated reinforced concrete structures manufactured under controlled factory conditions guarantee the highest quality of workmanship and full tightness eliminating the risk of environmental contamination. The modular system allows the capacity to be adapted to any size of farm.

The production of slurry tanks is based on the use of concrete of minimum class C35/45 with a compressive strength of 45 MPa and watertightness of W8. Increased cement content and sealing additives ensure the structural integrity of the concrete. A-IIIN steel reinforcement at 80-120 kg/m³ protects against scratching from hydrostatic loads.

Construction of prefabricated slurry tanks

The slurry tank is made as a monolithic cylindrical or rectangular structure from prefabricated elements joined on site. The system of concrete circles with a diameter of 3-8 m and a height of 1-2 m allows for quick installation. The bottom of the tank is a 20-30 cm thick reinforced concrete slab with a profiled slope to the collection sump.

An alternative is slurry tanks made of large-scale wall segments mounted on a prepared foundation slab. The height of the walls of 3-5 m allows the construction of tanks with a capacity of 500-3000 m³. A system of expansion joints sealed with bentonite tapes ensures tightness of connections.

Legal requirements for slurry tank regulations

According to the current standards, the slurry tank regulations define the minimum capacity as the product of 6 months of production and the number of LU on the farm. For cattle it is assumed 20 m³/DJP/year, for pigs 8 m³/DJP/year, for poultry 3.5 m³/DJP/year. The reservoir must have a capacity reserve of 20% for rainwater and process water.

The slurry tank system must meet the requirements of the Nitrate Directive limiting nitrogen application to 170 kg N/ha/year. Watertight construction with no possibility of infiltration into the ground. Mandatory manure slab for manure leachate. Design documentation in accordance with the Construction Law.

Types and capacities of tanks

Standard 20m3 slurry tanks are a solution for small farms up to 10 LU. Popular capacities are: 100 m³ (up to 30 LU of cattle), 200 m³ (60 LU), 500 m³ (150 LU), 1000 m³ (300 LU), 2000 m³ (600 LU). Modular tanks allow expansion when livestock numbers increase.

Special concrete slurry tanks with cover eliminate ammonia and odor emissions. Floating membrane system or reinforced concrete floors. Agitator systems prevent sedimentation and drossing. Two-chamber tanks allow methane fermentation.

Advantages of a prefabricated slurry tank

Application of manure tank on farms

The manure tank is used in all types of livestock farms as a mandatory component of the manure management system. Prefabricated structures adapt to the specifics of different types of farming – dairy cattle, pigs, poultry or mixed production. The modular system allows optimal adaptation to the size of the herd and the system of keeping animals.

Dairy farms

On dairy cattle farms, manure tanks with a capacity of 500-2000 m³ store manure from free-stall barns. A system of slotted grates and slurry channels transports manure directly to the tank. With a stocking rate of 100 cows, a minimum capacity of 400 m³ is required, plus a reserve for rainwater.

The manure tank on organic farms must allow separation of manure from different groups of animals. Multi-chamber tanks allow separate storage of manure from the grazing and barn periods. The system meets the requirements for organic certification.

Pig farms

Industrial piggeries require slurry tanks with increased resistance to high ammonia concentrations. Capacity of 1000-5000 m³ for farms over 1000 head. Covered tanks reduce nuisance odor emissions. A biofilter system in the ventilation reduces the spread of odors.
