Drainlaying is any work involving the installation, alteration or repairs to a drain.
Effective and correctly installed drainage systems play an important role in protecting public health and maintaining a pollution-free environment. If foul water is not correctly disposed of it can pose a significant risk both to the community at large and to our environment.
Drains are underground pipes which carry foul or surface water (stormwater) and enter either an onsite waste water disposal system (septic tank) or a sewer which is likely to be controlled by a territorial authority (district council).
The most common problem that occurs with a drain is blockage. Blockages occur for a number of reasons; foreign matter dropped down the drain, tree root intrusion, overloading, collapse, misalignment. A blockage in a drain will usually require the services of a tradesperson who can clear the blockage. Clearing a blocked drain is not regarded as drainlaying, however, anytime a drain is opened up, altered, reconstructed, extended or repaired then that work can only be legally undertaken by a licensed drainlayer.
