Make sure your drainage system is well planned
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. Correct gradients are used for this purpose. The system uses mostly UPVC tubing. It is important to adequately test the laid system before its commissioning. This must be carried out between the inspection chambers.
Drainage pipes need to be laid down in channels dug in the earth. Three hundred to five hundred millimeters is the typical depth adopted. Drainage lines running under a walkway, driveway or parking area are installed with a concrete casing. Before the construction of the drains, it is better to dig the earth to the recommended levels and check the gradients. The trenches should lead to or directed towards the tanks or sewers, away from the home. The drop or slope is generally in the ratio of 1:4 to facilitate water flow in a controlled way. The bottoms of the trenches are usually highly compressed. To fix the levels in these bottoms, one can use pegs.
It is necessary to lay the drainage pipes in a straight line without curves or kinks. The pipes are then linked to sockets inclining upward or to a building. A firm and uniform bed for the pipes has to be ensured. A good adhesive for the joints should be used for joining the male and female sockets. Read the instructions that come with the adhesive carefully and make sure that all of them are followed well. 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. 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. Septic tanks or sewers can now be connected. Connect the utilities to the drain lines to complete the drainage system.
