Make sure the drain system is well planned







Make sure the drain system is well planned

Effluents are transported from the utilities to the sewer or septic tank with the help of drainage pipes. In sewer systems from houses, pipes are laid in between inspection chambers. The system must be able to clean itself without blockage. The use of correct gradients is a must here. The system uses mostly UPVC tubing. Once laying has been carried out, it is vital to test the system fully before putting it into commission. The testing has to be conducted on the drain lines running between the chambers.

The laying down of drainpipes should be done in indents in the ground. The average depth for the pipes can range from 300 to 500 millimeters. Such sewer systems are enclosed in concrete when they pass below driveways, walkways or under a parking. To begin laying the lines, first excavate the trenches to the necessary depths. These should be graded towards the the tanks or sewers. The drop or slope is generally in the ratio of 1:4 to facilitate water flow in a controlled way. Proper packing, integrating and cramming of the trench base is usually done to provide a firm foundation. Pegs can be used to set accurate levels in the trench bottoms.

It is necessary to lay the drainage pipes in a straight line without curves or kinks. Sockets enable connecting of the pipes and directing them towards the building. A firm and uniform bed for the pipes has to be ensured. Male and female sockets should be connected using good quality adhesive. Make sure that you follow all the instructions for the adhesive, as specified by the manufacturer. The pipes must go into the full depth of the wall, while linking to the inspection chambers. The drainpipes should be kept free of foreign matter.

Check all the drain pipes before installing them. This is important to make sure that there is no leakage. Ensure the socket recesses are formed in the foundation. In addition, their length should be kept to a minimum. 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. Connect to the sewer or septic tank. Connect the utilities to the drain lines to complete the drainage system.
