Leak Noise Logger Programs in Vancouver, BC

Because that is when legitimate water use bottoms out and ambient noise dies. A leak runs at 3 a.m. exactly as it runs at noon — customer demand doesn't. Persistent noise in the minimum-demand window, repeated across several nights, is the cleanest leak signature a distribution system produces. Daytime crew surveys fight traffic and demand noise; loggers simply wait it out.

Lift-and-shift suits most BC systems: a modest logger fleet leapfrogs zone by zone, each zone getting one to two weeks of nights, until the network is covered — then repeats on a cycle. Permanent deployment suits chronic-loss zones, critical mains, and utilities that want standing surveillance feeding their operations. Many systems run both: permanent coverage on the worst zones, lift-and-shift everywhere else. We design and run either, and pair naturally with our real-time water loss monitoring service.

No — they aim it. A logger says 'there is persistent leak-like noise near this chamber'; it does not put a paint mark on the road. Correlation and ground microphone work still localise the dig. The economics improve because crews spend their hours confirming ranked POIs instead of walking quiet pipe — on large networks that typically cuts crew time dramatically.

Vancouver ground is predominantly glacial till uplands with deltaic sands toward False Creek and Fraser flats. Till and sand image well — 400 MHz reaches 2–3 m across most of the city; signal shortens in fill zones around False Creek and the port lands. For leak work that cuts two ways: it shapes whether escaping water surfaces or vanishes, and it influences how leak noise carries to our sensors — both factored into how we run leak noise logger programs here, and into when we recommend pairing the aerial thermal screen with the ground crews.

Pre-1965 oil-tank-era homes on the west side, post-tensioned towers downtown, and some of BC's oldest buried services in Strathcona and Mount Pleasant. The water mains underneath broadly track that growth story — each construction era left its pipe materials behind, from early metallic stock through the postwar asbestos-cement years to modern PVC — and each material gets matched methods in our survey design.

Where the data quality requires it, yes — minimum-demand hours give the cleanest acoustic and flow readings, and noise loggers do their listening at 2–4 a.m. by design. Scheduling is coordinated with your operations staff, Mon–Sat, and active breaks get priority response. 604-239-9934.
