Make sure the sewer system is well designed
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. This drainage setup must be self-cleaning, with running wastewater doing the flushing. The appropriate gradients are used to attain this. Normally UPVC pipework is employed in the sewer system. Its important after laying to sufficiently test before commissioning the system. This must be carried out between the inspection chambers.
It is necessary to install drainage pipes in trenches. The standard trench depth that is used is between three hundred and five hundred millimeters. Concrete casing is required for the system when it is laid below a parking area, walkway or driveway. Removing the earth to the appropriate levels is important before the inception of the work. The trenches have to be sloped towards the sewer or septic tank. 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.
Drainage pipes should be laid in a straight line. The pipes are then linked to sockets inclining upward or to a building. The sewer system should be placed on a solid, smooth and flat ground. Male and female sockets should be used to join the pipes using a good adhesive. Follow the manufacturer’s instructions while using the adhesive. Pipes must fit exactly into the thickness of the wall, during connection to the inspection chambers. The pipes should remain clean.
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. Ensure the socket recesses are formed in the foundation. Keep them short where possible. The inlet and outlet points must be evened out and marked appropriately. Once all joints are done, wrap the system and cover with soil. Connect to the sewer or septic tank. The drainage is finally completed by connecting the utilities to the tank.
