Services First Limited's designs and layouts fully detail the drainage & sewer networks on & offsite complete with gradients, pipe sizes & invert levels. Cover levels and pipe materials can also be displayed if required. A comprehensive legend would allow the recipient to distinguish between different types & sizes of manholes & inspection chambers, gullies, type of drainage run (foul, SW, combined, land drainage, etc) and other ancillary facilities such as pump stations, head walls, flow restrictions, etc. Special drainage protection measures would be addressed as required through your-selves or your nominated Ground investigator / Structural Engineers.

All designs would conform to the requirements of BS EN 752,

The Building Regulations Part H, and Sewers for Adoption 6th Edition and BRE 365 (soakaways).

Drainage calculations and/or analysis would accompany any submission as would all relevant adoptable / private standard drainage construction details.
