Do not create drainage problems with a badly designed drainage system
You may be aware that your drainage pipe system is designed to move effluents into the septic tank. They are also used in the sewer system in our homes where they are used in between the inspection chambers. The system should be self cleaning and prevent blockage. The use of correct gradients is a must here. UPVC tubing is often adopted in modern systems. Once the system has been laid down, testing should be carried out prior to inaugurating the system. Particular attention should be paid to the pipes between the inspection chambers.
Drainage pipes need to be laid down in channels dug in the earth. Trench depth has to be between 300 to 500 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 should lead to or directed towards the tanks or sewers, away from the home. A one to four ratio is appropriate for the incline. The bottom of the trenches should be rammed and compacted properly. To fix the levels in these bottoms, one can use pegs.
The pipeline has to be aligned straight. Sockets that lead uphill or in the direction of the building must be used for joining the separate pipes. An even and solid ground is required for laying the system throughout its length. When connecting male and female sockets with joints, a good adhesive should be used. Follow the manufacturer’s instructions while using the adhesive. The pipe should be thickest in the area where it is being connected to the inspection chambers. Remove the accumulated debris from the pipes whenever possible.
Inspect and scrutinise the drainage pipes while laying them. This is to ensure they are not punctured. Confirm the correct formation of the socket recesses in the foundation. However they should not be too long. The entry and exit points in an inspection chamber should be level and well graded. Once all joints are done, wrap the system and cover with soil. Complete the connection to the sewer or septic tank. The drainage is finally completed by connecting the utilities to the tank.
