How to prepare a self cleansing well constructed drainage system
Drainage pipes are used in the system of removing effluent from utilities to the sewer or septic tank. They are also used in the sewer system in our homes where they are used in between the inspection chambers. The system is supposed to keep itself clean and prevent the occurrence of any blockage. The use of correct gradients is a must here. Normally UPVC pipework is employed in the sewer system. Its important after laying to sufficiently test before commissioning the system. 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. 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. The trenches have to be sloped towards the sewer or septic tank. One to four is the acceptable ratio of the slope to be created. 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. The pipes should then be connected with sockets so that it can finally reach up to the building. The sewer system should be placed on a solid, smooth and flat ground. 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. The pipes must go into the full depth of the wall, while linking to the inspection chambers. Remove the accumulated debris from the pipes whenever possible.
Check all the drain pipes before installing them. This is done to avoid using punctured pipes which will leak over time. Confirm the correct formation of the socket recesses in the foundation. They should be limited to the minimum length. The points at which pipes enter and leave an inspection chamber should be on a level with each other and properly graded. The system is then buried beneath soil when all the joints have been finished and checked. Connection is then made between the system and the septic tank or sewer. Connect the utilities to the drain lines to complete the drainage system.
