An offence under subsection (1) or (3) above shall constitute a breach of a duty owed to the water undertaker in question; and any such breach of duty which causes the undertaker to sustain loss or damage shall be actionable at the suit of the undertaker.

The amount recoverable by virtue of subsection (6) above from a person who has committed an offence under subsection (3) above shall include such amount as may be reasonable in respect of any water wasted, misused or improperly consumed in consequence of the commission of the offence.

A water undertaker may—

do all such work as is necessary for repairing any injury done in contravention of subsection (5) above; and
recover the expenses reasonably incurred by the undertaker in doing so from the offender summarily as a civil debt.
