Acoustic Water Main Survey in White Rock, BC

The acoustic water main survey is the foundational method for municipal leak detection. Technicians systematically listen at every accessible point on the water network — hydrants, valves, blow-offs, and meter chambers — using advanced ground microphones and correlators to detect the characteristic sound of water escaping from pressurised pipes. Each listening point is logged with GPS coordinates and acoustic readings, building a comprehensive picture of network condition. This method identifies leaks that may have been active for months or years, gradually eroding pipe bedding and wasting thousands of litres daily without surfacing. Acoustic surveying is the most cost-effective first step in any municipal water loss management program.
