Drainage system blackspots you must fend off
Drainage system blackspots you must fend off
You may be aware that your drainage pipe system is designed to move effluents into the septic tank. Pipelines connecting houses to septic tanks include some inspection chambers so that you can check the status of the pipe or tackle a blockage without digging up the pipe. The entire sewer system must be constructed in such a way that it has the ability to self cleanse without developing blockages. A proper slope is required to ensure this smooth flow. Normally UPVC pipework is employed in the sewer system. 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 must be placed in trenches. They can be three to five hundred millimeters in depth. A system is surrounded in concrete when it is passed below sidewalks, driveways or parking areas. Removing the earth to the appropriate levels is important before the inception of the work. Carry out grading towards the tanks or sewers to ensure water flow. The drop or slope is generally in the ratio of 1:4 to facilitate water flow in a controlled way. The bottom of the trenches must be well compressed and jammed to give a secure base. Use pegs to set the levels in the trench bottoms.
The pipeline has to be aligned straight. This should be joined with sockets leading uphill or 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. Check the words of the supplier of the gluing material. At the joint of the pipe and inspection chamber, the pipe must be fixed properly upto the full wall thickness of the chamber. Remove the accumulated debris from the pipes whenever possible.
Inspect and scrutinise the drainage pipes while laying them. This is to ensure they are not punctured. Ensure the socket recesses are formed in the foundation. Keep them short where 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. Next, it should be connected with the sewer or septic tank. Complete the drainage system by connecting the utilities and test the full system.
