Commentary Part 1.Water Industry Expansion of water supply licensing Section 2: The supply system of a water undertaker
43.This section adds a new subsection (4A) to section 17B of WIA that extends the meaning of a water undertaker’s “supply system” for the purposes of activities under a water supply licence in the areas of water undertakers wholly or mainly in England. The current definition only covers the mains and pipes of a water undertaker downstream of a water treatment works (often called the “potable” supply system) and discrete non-potable supply systems. This is extended to cover treatment works, reservoirs and other water storage facilities. This means that a water supply licensee with a wholesale authorisation will have more options to introduce water for the purpose of supplying premises. The existing definition for the supply systems used by undertakers wholly or mainly in Wales is retained.
