Environmental engineering construction of sewers involves the following steps: Setting out - Alignment and gradient - Excavation of trenches, timbering, and dewatering - Laying and jointing - Testing - Backfilling  Sewer appurtenances are accessories that are necessary for the efficient operation of the sewerage system. They are structures and devices that are constructed at suitable intervals along a sewer line. Some examples of sewer appurtenances include:  Manholes, Lamp holes, Street inlets, Catch basins, Inverted siphons, Terminal cleanouts, Flush tanks, Service connections,... Show more
