How to prepare a self cleansing well built drainage system
Drainage pipes are often used in systems which carry the waste products from utilities to the septic tank. Household sewer systems have pipe lines running from inspection chamber to chamber. The entire sewer system must be constructed in such a way that it has the ability to self cleanse without developing blockages. Appropriate gradients are used to accomplish this. The system uses mostly UPVC tubing. Once laying has been carried out, it is vital to test the system fully before putting it into commission. The testing should be performed in between the inspection chambers.
Trenches should be dug and the drainage pipes should be laid in them. They can be three to five hundred millimeters in depth. Drainage lines running under a walkway, driveway or parking area are installed with a concrete casing. Excavation of the channel to the desired level must be done at the time of work commencement. The trenches should lead to or directed towards the tanks or sewers, away from the home. Maintain a one to four ratio for the slope you create. 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.
Drainage pipes should be laid in a straight line. The pipes are then linked to sockets inclining upward or to a building. The system should lie on a solid and even ground. In order to connect the female and male sockets, it is necessary to employ a first-rate adhesive which will last. The adhesive pack comes with instructions, make sure they are strictly followed. Ensure that the pipe goes into the full wall thickness during connection to the various inspection chambers. The drainpipes should be kept free of foreign matter.
When laying the drainpipes, they should be thoroughly inspected. This is to ensure they are not punctured. Make certain that the hooks of the sockets are firmly fixed in the foundation. Keep them short where possible. The two ends of inspection chambers- for entry and exit- must be evenly finished to the proper slope. The system is then covered with soil after all joints are complete. Septic tanks or sewers can now be connected. After this connect to the utilities to complete the drainage.
