Dig your ditches well for your drain system
You may be aware that your drainage pipe system is designed to move effluents into the septic tank. For household sewer systems, the inspection chambers are connected by pipes between them. This system should be capable of self-cleaning without causing a blockage. Correct gradients are used for this purpose. It is UPVC tubing that is primarily employed. However testing is very important before the system can start functioning. The correct location for testing is between the inspection chambers.
Drainage pipes need to be laid down in channels dug in the earth. The standard trench depth that is used is between three hundred and five hundred millimeters. A system is surrounded in concrete when it is passed below sidewalks, driveways or parking areas. Excavate to the necessary levels when beginning the project. These should be graded towards the the tanks or sewers. Maintain a slope of one in four for the excavated channels. The bottom of the trenches should be rammed and compacted properly. Employ marking lines to position the trench bottoms to their correct levels.
Drainage pipes should be laid in a straight line. The pipes should be connected with sockets leading uphill or in the direction of the building. The system should lie on a solid and even ground. A good adhesive for the joints should be used for joining the male and female sockets. 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. Avoid debris inside the pipes as it will impede water flow.
Check all the drain pipes before installing them. This is to ensure they are not punctured. Be sure to check the foundation contains the socket recesses to accommodate the external shape of the drains. In addition, their length should be kept to a minimum. Good leveling and grading must be provided at the entry and exit points in an inspection chamber. Once all the joints are finished, the whole system is then covered over with earth. Connection is then made between the system and the septic tank or sewer. Complete the drainage system by connecting the utilities and test the full system.
