The blueprint for a well planned drainage system

By: Al Higginson

Dig Out your trenches well for your sewer system

You may be aware that your drainage pipe system is designed to move effluents into the septic tank. They are also used in the sewer system in our homes where they are used in between the inspection chambers. The system must be able to clean itself without blockage. 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. This must be carried out between the inspection chambers.

The laying down of drainpipes should be done in indents in the ground. The average depth is three hundred to five hundred millimeters. Concrete casing is required for the system when it is laid below a parking area, walkway or driveway. Before the construction of the drains, it is better to dig the earth to the recommended levels and check the gradients. These must be inclined towards the sewers or effluent storage tanks. The slope should be in the ratio of one is to four. It should be ensured that the foot of each trench is packed close and rammed. The level in the foot of a trench bottoms should be determined using pegs.

The pipeline has to be aligned straight. Sockets enable connecting of the pipes and directing them towards the building. Flat and well-compacted ground is best to lay the system upon. The female and male sockets should be joined firmly using a strong adhesive. The adhesive pack comes with instructions, make sure they are strictly followed. Pipes must fit exactly into the thickness of the wall, during connection to the inspection chambers. Pipes must be free of litter and internal obstructions.

When laying the drainpipes, they should be thoroughly inspected. This is to make sure they are not perforated. Make certain that the hooks of the sockets are firmly fixed in the foundation. They should also be kept as short as possible. The inlet and outlet of the inspection chamber must be even and ordered. Once all joints are done, wrap the system and cover with soil. Connection is then made between the system and the septic tank or sewer. Connect the utilities to the drain lines to complete the drainage system.
