If any person who is the owner or occupier of any premises to which a supply of water is provided by a water undertaker or water supply licensee intentionally or negligently causes or suffers any water fitting for which he is responsible to be or remain so out of order, so in need of repair or so constructed or adapted, or to be so used—
that person shall be guilty of an offence and liable, on summary conviction, to a fine not exceeding level 3 on the standard scale.
In any proceedings under subsection (1) above it shall be a defence to prove–
Any person who uses any water supplied to any premises by a water undertaker for a purpose other than one for which it is supplied to those premises shall, unless the other purpose is the extinguishment of a fire, be guilty of an offence and liable, on summary conviction, to a fine not exceeding level 3 on the standard scale.
Where a person has committed an offence under subsection (2) above, the water undertaker in question shall be entitled to recover from that person such amount as may be reasonable in respect of any water wasted, misused or improperly consumed in consequence of the commission of the offence.
For the purposes of this section the owner or occupier of any premises shall be regarded as responsible for every water fitting on the premises which is not a water fitting which a person other than the owner or, as the case may be, occupier is liable to maintain.
