The blueprint for a well constructed 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. The use of correct gradients is a must here. Drain lines mostly comprise of UPVC tubing. After laying the system, the next important step is to test it before completing work and closing the system. The testing has to be conducted on the drain lines running between the chambers.
The laying down of drainpipes should be done in indents in the ground. The standard trench depth that is used is between three hundred and five hundred millimeters. When the system passes below a parking, walkways or driveways, it is encased in concrete. Removing the earth to the appropriate levels is important before the inception of the work. The grading must be done near the sewers or the tank. One to four is the acceptable ratio of the slope to be created. The bottoms of the trenches are usually highly compressed. Use pegs to set the levels in the trench bottoms.
Drainage pipes should be laid in a straight line. When the pipes have to be fixed on a slope or towards the building, join the sections with sockets. A firm and uniform bed for the pipes has to be ensured. Male and female sockets can be interlaced by using a good binding material at the joints. When using the adhesive, the manufacturer’s instructions should be followed. At the joint of the pipe and inspection chamber, the pipe must be fixed properly upto the full wall thickness of the chamber. Keep debris off the pipes.
Before laying down the drainage pipes, they should be examined minutely for any defects. This is to make sure that the pipes are free of punctures. All socket recesses have to be adequately formed in the foundation. However they should not be too long. The two ends of inspection chambers- for entry and exit- must be evenly finished to the proper slope. After fixing all the joints properly, the system then needs to be wrapped up with soil. Link the system to the septic tank. After this connect to the utilities to complete the drainage.
