The constructors bible for developing a sewer system
Drainage pipes are often used in systems which carry the waste products from utilities to the septic tank. They are also used in the sewer system in our homes where they are used in between the inspection chambers. There should not be any clogging if the system cleans itself. This goal can be attained only if you adopt the right construction gradients to allow water to flow through the system. UPVC tubing is often adopted in modern systems. However testing is very important before the system can start functioning. The testing has to be conducted on the drain lines running between the chambers.
Drainage pipes should be laid in trenches. Trench depth has to be between 300 to 500 millimeters. When the system passes below a parking, walkways or driveways, it is encased in concrete. Excavation of the channel to the desired level must be done at the time of work commencement. The grading must be done near the sewers or the tank. Maintain a one to four ratio for the slope you create. It should be ensured that the foot of each trench is packed close and rammed. Use pegs to set the levels in the trench bottoms.
It is necessary to lay the drainage pipes in a straight line without curves or kinks. Sockets that lead uphill or in the direction of the building must be used for joining the separate pipes. A firm and uniform bed for the pipes has to be ensured. In order to connect the female and male sockets, it is necessary to employ a first-rate adhesive which will last. 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.
When the drainage pipes are laid, they must be explored and checked out carefully. This is to make sure that the pipes are free of punctures. The recesses of the socket should be made at the deepest point. They should also be kept as short as possible. The two ends of inspection chambers- for entry and exit- must be evenly finished to the proper slope. The system is then buried beneath soil when all the joints have been finished and checked. Link the system to the septic tank. Complete the drainage system by connecting the utilities and test the full system.
