The BPF Pipes Group has produced new guidance for designers, installers and engineers: Specifications for Plastic Pipes, Chambers, Manholes and Covers for Drainage and Sewerage Applications.  The BPF Pipes Group has produced new guidance for designers, installers and engineers: Specifications for Plastic Pipes, Chambers, Manholes and Covers for Drainage and Sewerage Applications.

The new guidance document sets out information on product standards for pipes, chambers, manholes and covers; which are current and what to use where for all applications from private drains to public sewers. 

The new guidance has been prepared ahead of the publication of two key documents, the European Standard BS EN 752: 2017 with its UK National Annex and Sewers for Adoption 8th edition for the design and construction of private and public drains and sewers. The revision of Sewers for Adoption, following hot on the heels of the European Standard, represents the first real opportunity for designers and installers to obtain clear and consistent advice covering the full spectrum, from private drains built to Building Regulations, through to publicly adopted sewers.

The document contains key information for those designing and installing sewer pipework, chambers and manholes, divided into five sections: Drains and Sewer Pipes; Inspection Chambers; Manholes; Covers for Inspection Chambers and Manholes; Proving the Integrity of the Wastewater System.  In each of the first four sections, the correct and current product specifications are identified and summarised, terminology is demystified, and key recommendations given. The final section succinctly explains the requirements for whole system integrity testing following construction.
