Step by step: how to place utility crossings and objects (manholes, roads, buildings) on a long-section profile in Altivo, how to edit their parameters and how to delete them.
Gravity sewer gradients in the UK: minimum and maximum slopes — BS EN 752 and Sewerage Sector Guidance
How to choose the slope of a gravity sewer in the UK: self-cleansing velocity, the 1/DN rule of thumb, minimum and maximum gradients, and which framework applies (BS EN 752 and the sewerage undertaker's DCG for public sewers; Building Regulations Part H for building drainage).
How to read a utility long section (longitudinal profile)
A practical guide to the long section of a water, sewer or gas network: ground line, pipe invert, gradients, stationing, the profile table and what a reviewer checks.
