                                            Sanitation systems must comply with Building Regulations Approved
                                            Document H1. The general requirements of this document are that a foul
                                            water system must:
                      INDUSTRY TIP          ●  convey the flow of foul water to a foul water outfall; this can be a foul or
                                               combined foul/rainwater sewer, a cesspool or septic tank
                 You can access Building    ●  minimise the risk of blockage and/or leakage
                 Regulations 2010 Approved   ●  prevent foul air from entering the building under working conditions
                 Document H1 at: www.gov.uk/  ●  be ventilated

                                            To successfully achieve this, we must consult several documents.

                                            BS EN 12056–5:2000: Gravity drainage systems inside
                                            buildings. Installation and testing, instructions for
                                            operation, maintenance and use
                                            This applies to waste water drainage systems that operate under gravity. It is
                                            applicable for drainage systems inside dwellings and commercial, institutional
                                            and industrial buildings.
