Why we acted

 

Maylands Police Complex occupies a site totalling approximately 200,000m2 set next to the Swan River in an area prone to flooding. This complex experiences a diverse site use and is occupied by staff 24 hours a day, adding complexity to understanding regular water usage patterns.

How we did it

A site walk through resulted in no obvious water leaks, which was a difficult task given it was winter and this site is located beside the Swan River.

A plumber was then engaged who was unable to located any obvious leaks throughout the site and associated buildings.

To isolate the possibility of a pool leak the pool auto top-up was turned off and main meter reads continued. The pool was ruled out after careful analysis of the sub-meter readings.

WA Police organised a leak detection specialist who spent two days on site tracing water mains and ring wains through the site with electronic water detectors and had no result.

Original hydraulic drawings from the 1960s were obtained.

A wet patch was noticed during a period of dry weather.

A leak was located in a pipe one meter below the surface close to a demountable building and repaired the same day. This location was extremely close to the river further complicating leak detection given it was during winter and the ground is often wet.
