Make certain the drain system is well designed
The system for removing pollution from utilities to a septic tank or sewer uses drainage pipes. For household sewer systems, the inspection chambers are connected by pipes between them. There should not be any clogging if the system cleans itself. The appropriate gradients are used to attain this. 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. 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 sewer system passes under a walkway, car park area or driveway, the pipe must be enveloped in concrete to protect it. When commencing the work, excavate to the required levels. 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. It should be ensured that the foot of each trench is packed close and rammed. The level in the foot of a trench bottoms should be determined using pegs.
The drainage pipes should never be laid down haphazardly, they are to be put in a straight line. Sockets enable connecting of the pipes and directing them towards the building. An even and solid ground is required for laying the system throughout its length. The female and male sockets should be joined firmly using a strong 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 drainpipes should be kept free of foreign matter.
When laying the drainpipes, they should be thoroughly inspected. This is important to make sure that there is no leakage. All socket recesses have to be adequately formed in the foundation. In addition, their length should be kept to a minimum. The inlet and outlet points must be evened out and marked appropriately. Once all joints are done, wrap the system and cover with soil. Septic tanks or sewers can now be connected. Complete the drainage system by connecting the utilities and test the full system.
