Do not create sewer problems with a badly designed sewer system
Effluents are transported from the utilities to the sewer or septic tank with the help of drainage pipes. Household sewer systems have pipe lines running from inspection chamber to chamber. The system should be self cleaning and prevent blockage. The use of correct gradients is a must here. The most commonly used gradient in these systems is the UPVC tubing. Once laying has been carried out, it is vital to test the system fully before putting it into commission. The tests must be conducted in between the inspection chambers to allow each part of the system to be thoroughly checked.
It is necessary to install drainage pipes in trenches. They can be three to five hundred millimeters in depth. Such sewer systems are enclosed in concrete when they pass below driveways, walkways or under a parking. When commencing the work, excavate to the required levels. These must be inclined towards the sewers or effluent storage tanks. A one to four ratio is appropriate for the incline. Ensure that the bottom of every trench is well rammed to get a uniformly compacted surface. In order to strengthen the bottom of the trench, fasten it and fix it.
It is necessary to lay the drainage pipes in a straight line without curves or kinks. The pipes are then linked to sockets inclining upward or to a building. Flat and well-compacted ground is best to lay the system upon. The female and male sockets should be joined firmly using a strong adhesive. Ensure the manufacturers instructions are followed with the adhesive. Pipes must fit exactly into the thickness of the wall, during connection to the inspection chambers. The pipes should remain clean.
Thorough inspections are carried out on the drainage pipe before it is laid in the channel. This is to ensure they are not punctured. Be sure to check the foundation contains the socket recesses to accommodate the external shape of the drains. Keep them short where possible. The entry and exit points in an inspection chamber should be level and well graded. Once all joints are done, wrap the system and cover with soil. Make the final connections to the sewer or septic tank. To complete the procedure, create a connection between the drainage system and the utilities’ supply.
