Dig your trenches well for your drainage system
Dig your trenches well for your drainage system
Drain pipes carry waste effluent from your fixtures down to the sewage system. For household sewer systems, the inspection chambers are connected by pipes between them. The system should be self cleaning and prevent blockage. A proper slope is required to ensure this smooth flow. UPVC tubing is mainly used in the system. However testing is very important before the system can start functioning. The testing has to be conducted on the drain lines running between the chambers.
Trenches should be dug and the drainage pipes should be laid in them. Depth averages between thirty and fifty centimeters. Concrete structure is built to shield the system in case there is a walkway, parking zone or driveway above it. When commencing the work, excavate to the required levels. These must be inclined towards the sewers or effluent storage tanks. Maintain a slope of one in four for the excavated channels. The bottoms of the trenches are usually highly compressed. Pegs can be used to set accurate levels in the trench bottoms.
Drainage pipes should be laid in a straight line. The pipes should be connected with sockets leading uphill or in the direction of the building. The ground containing the system should be compacted and consistent. Male and female sockets should be used to join the pipes using a good adhesive. The adhesive pack comes with instructions, make sure they are strictly followed. Ensure that the pipe goes into the full wall thickness during connection to the various inspection chambers. Pipes must be free of litter and internal obstructions.
Check all the drain pipes before installing them. This is to make sure that the pipes are free of punctures. All socket recesses have to be adequately formed in the foundation. They should be limited to the minimum length. The entry and exit points in an inspection chamber should be level and well graded. After completing all joints cover the system with soil. Connect to the sewer or septic tank. The drainage is finally completed by connecting the utilities to the tank.
