Part 5: Water Section 80: Storm overflows New section 141E Interpretation of Chapter 4
New section 141E sets out the definition of a storm overflow and discharges from storm overflows.
	Subsection (1) defines a storm overflow in relation to structures and the apparatus of a sewerage undertaker’s sewerage system.
	Subsection (2) defines sewerage discharges which are not defined as storm overflows and are therefore exempt from the requirements of new chapter 4 (storm overflows) of Part 4 of the Water Industry Act 1991. These include discharges which occur because of an asset failure.
	Subsection (3) explains that a ‘sewerage system’ as specific in subsection (1) is defined by way of section 17BA(7) of the Water Industry Act 1991 which states the following: "References in this Chapter to the sewerage system of a sewerage undertaker are references to the system comprising (a) the system of public sewers, the facilities for emptying public sewers and the sewage disposal works and other facilities for dealing effectually with the contents of public sewers that the undertaker is required to provide by section 94, and (b) the lateral drains that the undertaker is required to maintain by section 94.".
