Sewer system design including self cleaning features
Drainage pipes are often used in systems which carry the waste products from utilities to the septic tank. In sewer systems from houses, pipes are laid in between inspection chambers. The entire sewer system must be constructed in such a way that it has the ability to self cleanse without developing blockages. This is achieved by having the correct gradients. The system uses mostly UPVC tubing. Once the system has been laid down, testing should be carried out prior to inaugurating the system. The testing should be performed in between the inspection chambers.
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 grading must be done near the sewers or the tank. The ratio of the slope is to kept in mind, it should be 1 is to 4. The trench bottoms are well compacted and rammed. Use pegs to set the levels in the trench bottoms.
Maintaining straight lines is essential while laying down the drainage pipes. Sockets enable connecting of the pipes and directing them towards the building. The ground on which the systems lies should be even and solid. The female and male sockets should be joined firmly using a strong adhesive. 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. Remove the accumulated debris from the pipes whenever possible.
Thorough inspections are carried out on the drainage pipe before it is laid in the channel. This is to guarantee that the pipes are not damaged at any points and do not have holes or cracks. Make certain that the hooks of the sockets are firmly fixed in the foundation. These recesses should be kept short and compact. The entry and exit points in an inspection chamber should be level and well graded. After all joining work is complete, backfill the trenches to required level. Next, it should be connected with the sewer or septic tank. To complete the procedure, create a connection between the drainage system and the utilities’ supply.
