Non-Revenue Water (NRW) Program in Penticton, BC

Everything produced that doesn't end up billed: real losses (leakage from mains, services, appurtenances, reservoir overflow), apparent losses (meters under-registering, billing data gaps, unauthorised use), and unbilled authorised use (flushing, firefighting). The split matters enormously — real losses are fixed with detection and repair; apparent losses are fixed with meter and billing work; the fixes share no budget. The water balance exists to make that split before money gets spent on the wrong half.

Industry reporting consistently puts typical systems in that band, with well-managed networks below it and older, hillier, or long-neglected systems above. BC's mix — postwar AC pipe, mountain pressure zones that stress mains, and small systems with thin staffing — spans the whole range. Your own production and billing records, run through a proper balance, answer the question for your system in weeks; guessing is free and worth it.

Three stacked values: the marginal production cost of every cubic metre no longer leaked (treatment, pumping energy, chemicals); deferred capital where supply or treatment capacity is tight — recovered leakage is new capacity at a fraction of expansion cost; and resilience under drought restrictions, where every leaked litre is a litre your residents were told not to use. Programs are designed so located-leak recovery outruns program cost — that's the point of payback-ordered sequencing.

Penticton ground is predominantly deep dry sands between two lakes — arguably BC's best natural GPR ground. The sand benches between Okanagan and Skaha lakes return 4 m+ penetration on a good day; almost nothing hides here from a properly run survey. 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 non-revenue water (nrw) program here, and into when we recommend pairing the aerial thermal screen with the ground crews.

Beach-strip motels and condos, vineyard benches, and postwar grid neighbourhoods. 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.
