The builders bible for designing a sewer system
The system for removing pollution from utilities to a septic tank or sewer uses drainage pipes. They are also used in the sewer system in our homes where they are used in between the inspection chambers. The system is supposed to keep itself clean and prevent the occurrence of any blockage. This is achieved by having the correct gradients. Normally UPVC pipework is employed in the sewer system. After laying the system, the next important step is to test it before completing work and closing the system. The tests must be conducted in between the inspection chambers to allow each part of the system to be thoroughly checked.
Drainage pipes should be laid in trenches. The standard trench depth that is used is between three hundred and five hundred millimeters. Concrete casing is required for the system when it is laid below a parking area, walkway or driveway. Excavate to the necessary levels when beginning the project. Carry out grading towards the tanks or sewers to ensure water flow. Maintain a one to four ratio for the slope you create. The bottom of the trenches should be rammed and compacted properly. The level in the foot of a trench bottoms should be determined using pegs.
Maintaining straight lines is essential while laying down the drainage pipes. The pipes are then linked to sockets inclining upward or to a building. The sewer system should be placed on a solid, smooth and flat ground. Male and female sockets should be used to join the pipes using a good adhesive. Ensure the manufacturers instructions are followed with the adhesive. Ensure that the pipe goes into the full wall thickness during connection to the various inspection chambers. Clean any debris from the pipes.
When the drainage pipes are laid, they must be explored and checked out carefully. This is done to avoid using punctured pipes which will leak over time. Ensure the socket recesses are formed in the foundation. Keep them short where possible. The inlet and outlet points must be evened out and marked appropriately. After fixing all the joints properly, the system then needs to be wrapped up with soil. Link the system to the septic tank. Complete the drainage system by connecting the utilities and test the full system.
