Biogas plants Biogas plants generate electrical energy by means of fermentation substrates of agricultural origin, among other things. In accordance with DWA -A 793 (TRwS 793) and the WHG regulations, all wastewater pipes that discharge substances hazardous to water must be friction-locked, i.e. welded or bonded. Storage tanks must in many cases be double-walled and…

When storing silage in a flat silo, the escaping fermentation juice is the cause of the special requirements placed on the structural system. Defective JGS facilities, such as silo…
Slurry transport lines Pipeline systems for slurry transport are usually designed large dimensions. In order to be able to transport the quite viscous slurry in the free fall, it is necessary to resort to dimensions between DN 400 and 600 mm. Due to the large volume, increased attention must be paid to the tightness of…
Sprinkling and irrigation systems Systems for the sprinkling or trickling of polluted rainwater in the JGS area are used to distribute polluted rainwater over large areas on vegetated otherwise unused areas. The aim is to treat this biologically low-polluted wastewater by infiltration through the living soil zone before it is insured into the groundwater. As…
Stables Stables are designed for different animal husbandry and requirements. What they all have in common, however, is the need for defined drainage in accordance with the Water Resources Act (WHG) § 62. As a result, DWA-A 792 (TRwS 792) must be taken into account with regard to wastewater technology. This regulation requires, among other…
Manure storage / manure plates Manure and dung plates and are usually laid out with a downstream septic tank. Depending on the size of the bearing plate, the requirements of the Ordinance on Installations for Handling Substances Hazardous to Water (AwSV) and the Technical Rules for Substances Hazardous to Water (TRwS Worksheet DWA-A-792) must be…
Filling areas All areas and sites where liquid manure, leachate or other liquids hazardous to water are removed or transferred must be equipped with a removal point in accordance with DWA-A 792 (TRwS 792).
