How to prepare a self cleansing well fabricated sewer system
Drainage pipes are often used in systems which carry the waste products from utilities to the septic tank. They are also used in the sewer system in our homes where they are used in between the inspection chambers. The system must be able to clean itself without blockage. The appropriate gradients are used to attain this. It is UPVC tubing that is primarily employed. It is essential to test the drainage system properly before allowing its use. Particular attention should be paid to the pipes between the inspection chambers.
It is necessary to install drainage pipes in trenches. Depth averages between thirty and fifty centimeters. Drainage lines running under a walkway, driveway or parking area are installed with a concrete casing. Removing the earth to the appropriate levels is important before the inception of the work. These should be graded towards the the tanks or sewers. Maintain a slope of one in four for the excavated channels. It should be ensured that the foot of each trench is packed close and rammed. Use pegs to set the levels in the trench bottoms.
Maintaining straight lines is essential while laying down the drainage pipes. 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. The female and male sockets should be joined firmly using a strong adhesive. Ensure the manufacturers instructions are followed with the adhesive. At the joint of the pipe and inspection chamber, the pipe must be fixed properly upto the full wall thickness of the chamber. Remove the accumulated debris from the pipes whenever possible.
The drainage pipes are carefully examined when laying. This is to make sure that the pipes are free of punctures. Be sure to check the foundation contains the socket recesses to accommodate the external shape of the drains. Keep them short where possible. The points at which pipes enter and leave an inspection chamber should be on a level with each other and properly graded. After all joining work is complete, backfill the trenches to required level. Septic tanks or sewers can now be connected. And the final step is to link the system to the utilities to finish the drainage system and commence the final test.
