Drain Laying and Drainage

Drain laying and Drainage is the act of correctly installing and maintaining a pollution free, environmentally safe disposal system for foul water, in accordance to the laid down rules and regulations of the building code. The work is usually carried out by licensed and registered individuals or plumbing companies.

Underground pipes which carry storm and foul water are either connected to an onsite disposal septic tank, or to a larger sewer system that is under the control of the territorial district or jurisdiction authority. Incorrect disposal can pose significant risks to the community and the environment.

Laying out of drains is set within legal demarcated boundaries, with the issuance of a code compliance certificate taking place, after the work has been approved by a building inspector.

Drain layers can alter, reconstruct, repair, extend, and open drains and traps, for purposes of repair or unblocking, which may be caused by the presence of foreign debris, intrusion of tree roots, collapsing, misalignment and overloading. Hiring holders of current licenses who are legally compliant, is advisable.

Sewer and drainage pipes are manufactured from varying materials such as uPVC, vitrified clay, asbestos, ductile, cast iron, glass fiber reinforced plastics, pitch fiber, high density polyethylene, and concrete. Clay ware is considered better than plastic, due to its flexible adapter couplings that allow for connection to plastic or other pipes. Plastic pipes however, have a lighter aspect which has contributed to its increased current level of usage.

The entire Drain laying and Drainage process must observe safety measures such as, the use of barrier and security fencing, prohibitions of opening up trenches during inclement weather, maintaining the minimum regulated trench width, prohibitions of working alone within a trench without a banks man, and opening up of trenches far in advance of the laying process. Selected fill must be free from large stones, clay lumps, timber pieces, frozen material and organic debris.
