Drainage channel systems and penetrations in MSS and biogas facilities
Drainage channel systems and penetrations in retaining systems need to be designed in a way to ensure that no substances hazardous to water can escape from storage and filling facilities for manure, slurry and silage effluent (MSS facilities) and biogas storage and filling facilities (biogas SF facilities) into nearby bodies of water.
The penetrations described here are designed to seal pipe and cable penetrations in drainage surfaces for storage and filling areas of MSS and biogas SF facilities.
Please also note the applicable provisions of the federal states following MVV TB, B 4.1 'Technical requirements for stationary systems and system parts used in storage, filling and handling facilities for substances hazardous to water'.
Regulatory framework
Drainage channel systems and penetrations in MSS and biogas SF facilities fall under the Ordinance on the determination of the suitability of construction products and construction techniques under water law by means of verifications in accordance with the Building Codes of the federal states (WasBauPVO) and under the Ordinance on facilities for handling substances hazardous to water (AwSV).
DIBt grants national technical approvals (abZ) and/or general construction technique permits (aBG) for these products and construction techniques, confirming that both the construction and the water law requirements have been met.
The products and construction techniques are thus deemed to be suitable for biogas SF facilities in accordance with Section 63 of the Water Resources Act (WHG). The construction products and construction techniques may also be used or applied in MSS facilities in accordance with Annex 7 of the AwSV.

National procedure
A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.
No formal requirements apply.
