The design for a well constructed sewer system
The purpose of drainage pipes is to expel the discharge coming out from the home and direct it into the septic or sewer tanks. Household sewer systems have pipe lines running from inspection chamber to chamber. The system should be self cleaning and prevent blockage. Correct gradients are used for this purpose. It is UPVC tubing that is primarily employed. However testing is very important before the system can start functioning. Particular attention should be paid to the pipes between the inspection chambers.
Drainage pipes are positioned in trenches which have been pre-dug. The average depth is three hundred to five hundred millimeters. Such sewer systems are enclosed in concrete when they pass below driveways, walkways or under a parking. Excavation of the channel to the desired level must be done at the time of work commencement. Carry out grading towards the tanks or sewers to ensure water flow. 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. Employ marking lines to position the trench bottoms to their correct levels.
Maintaining straight lines is essential while laying down the drainage pipes. This should be joined with sockets leading uphill or towards the building. The ground containing the system should be compacted and consistent. A good adhesive for the joints should be used for joining the male and female sockets. Follow the manufacturer’s instructions while using the adhesive. When connecting to the inspection chambers, the pipe should go into the full wall thickness. Clean any debris from the pipes.
When laying the drainpipes, they should be thoroughly inspected. Make sure that they are not punctured at any point. Ensure the socket recesses are formed in the foundation. They should be limited to the minimum length. The two ends of inspection chambers- for entry and exit- must be evenly finished to the proper slope. After completing all joints cover the system with soil. Septic tanks or sewers can now be connected. And the final step is to link the system to the utilities to finish the drainage system and commence the final test.
