Drainage pipes are used in the system of removing effluent from utilities to the sewer or septic tank. In sewer systems from houses, pipes are laid in between inspection chambers. The system must be able to clean itself without blockage. This is achieved by having the correct gradients. The system uses mostly UPVC tubing. Its important after laying to sufficiently test before commissioning the system. This should be done between the inspection chambers.

Drainage pipes should be laid in trenches. The average depth is three hundred to five hundred millimeters. When the system passes below a parking, walkways or driveways, it is encased in concrete. When commencing the work, excavate to the required levels. These should be graded towards the the tanks or sewers. The slope should be in the ratio of one is to four. The trench bottoms are well compacted and rammed. Use pegs to set the levels in the trench bottoms.

Drainage pipes should be laid in a straight line. This should be joined with sockets leading uphill or towards the building. The system should lie on a solid and even ground. A good adhesive for the joints should be used for joining the male and female sockets. Ensure the manufacturers instructions are followed with the adhesive. When connecting to the inspection chambers, the pipe should go into the full wall thickness. Keep debris off the pipes.

The drainage pipes are carefully examined when laying. This is to ensure they are not punctured. Ensure the socket recesses are formed in the foundation. They should also be kept as short as possible. The entry and exit points in an inspection chamber should be level and well graded. The system is then covered with soil after all joints are complete. Connect to the sewer or septic tank. After this connect to the utilities to complete the drainage.
