Do not create drain problems with a badly designed drainage system
Drain pipes carry waste effluent from your fixtures down to the sewage system. In the case of the home sewer system, pipes are placed in between the inspection chambers. This drainage setup must be self-cleaning, with running wastewater doing the flushing. Correct gradients are used for this purpose. It is UPVC tubing that is primarily employed. Once the system has been laid down, testing should be carried out prior to inaugurating the system. The testing has to be conducted on the drain lines running between the chambers.
It is necessary to install drainage pipes in trenches. They can be three to five hundred millimeters in depth. When the sewer system passes under a walkway, car park area or driveway, the pipe must be enveloped in concrete to protect it. Removing the earth to the appropriate levels is important before the inception of the work. These must be inclined towards the sewers or effluent storage tanks. The drop or slope is generally in the ratio of 1:4 to facilitate water flow in a controlled way. Proper packing, integrating and cramming of the trench base is usually done to provide a firm foundation. Fix pegs at the base of each trench to set the required levels.
Set drain pipes straight and directly in line with one another. Sockets enable connecting of the pipes and directing them towards the building. The ground containing the system should be compacted and consistent. Male and female sockets should be connected using good quality adhesive. The adhesive pack comes with instructions, make sure they are strictly followed. At the joint of the pipe and inspection chamber, the pipe must be fixed properly upto the full wall thickness of the chamber. The pipes should remain clean.
The drainage pipes are carefully examined when laying. Make sure that they are not punctured at any point. All socket recesses have to be adequately formed in the foundation. These recesses should be kept short and compact. The inspection chamber’s entry and exit points need to be graded well, in addition to being leveled. The system is then covered with soil after all joints are complete. Next, it should be connected with the sewer or septic tank. To complete the procedure, create a connection between the drainage system and the utilities’ supply.
