Plan you drain system to last for the long term
The system for removing pollution from utilities to a septic tank or sewer uses drainage pipes. In the case of the home sewer system, pipes are placed in between the inspection chambers. This drainage setup must be self-cleaning, with running wastewater doing the flushing. A proper slope is required to ensure this smooth flow. 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. This should be done between the inspection chambers.
Drainage pipes must be placed in trenches. The average depth for the pipes can range from 300 to 500 millimeters. When the sewer system passes under a walkway, car park area or driveway, the pipe must be enveloped in concrete to protect it. Before the construction of the drains, it is better to dig the earth to the recommended levels and check the gradients. The grading must be done near the sewers or the tank. The slope should be in the ratio of one is to four. The trench bottoms are well compacted and rammed. Fix pegs at the base of each trench to set the required levels.
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. The ground on which the systems lies should be even and solid. A good adhesive for the joints should be used for joining the male and female sockets. When using the adhesive, the manufacturer’s instructions should be followed. The pipes must go into the full depth of the wall, while linking to the inspection chambers. Clean any debris from the pipes.
Before laying down the drainage pipes, they should be examined minutely for any defects. This is to make sure they are not perforated. Confirm the correct formation of the socket recesses in the foundation. In addition, their length should be kept to a minimum. The inspection chamber’s entry and exit points need to be graded well, in addition to being leveled. After completing all joints cover the system with soil. Connect to the sewer or septic tank. And the final step is to link the system to the utilities to finish the drainage system and commence the final test.
