Drainage system designing including self cleaning features
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. The system must be able to clean itself without blockage. The use of correct gradients is a must here. It is UPVC tubing that is primarily employed. It is important to adequately test the laid system before its commissioning. The tests must be conducted in between the inspection chambers to allow each part of the system to be thoroughly checked.
The laying down of drainpipes should be done in indents in the ground. Trench depth has to be between 300 to 500 millimeters. Concrete structure is built to shield the system in case there is a walkway, parking zone or driveway above it. To begin laying the lines, first excavate the trenches to the necessary depths. The trenches have to be sloped towards the sewer or septic tank. The ratio of the slope is to kept in mind, it should be 1 is to 4. The bottom of the trenches must be well compressed and jammed to give a secure base. Pegs can be used to set accurate levels in the trench bottoms.
Maintaining straight lines is essential while laying down the drainage pipes. The pipes should then be connected with sockets so that it can finally reach up to the building. Flat and well-compacted ground is best to lay the system upon. Male and female sockets should be connected using good quality adhesive. Read the instructions that come with the adhesive carefully and make sure that all of them are followed well. Pipes must fit exactly into the thickness of the wall, during connection to the inspection chambers. The pipes should remain clean.
Inspect and scrutinise the drainage pipes while laying them. This is to make sure that the pipes are free of punctures. The foundation must have socket recesses for it is incomplete without them. The hooks must be as stunted and small as possible. 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. Connect to the sewer or septic tank. Complete the drainage system by connecting the utilities and test the full system.
