Nordic City Gains Valuable Condition Data With Proactive Approach To Reducing NRW

Gothenburg is Sweden’s second largest city after Stockholm, located between Oslo and Copenhagen in a low-lying estuary area near the Gota River, the primary source of drinking water for the port city. The City’s Sustainable Waste and Water Department serves a population of over 500,000, and manages 1750 km of potable water pipeline.

As part of a pre-emptive program to address non-revenue water loss and understand the condition of their pipes, Gothenburg wanted to conduct a condition assessment and leak detection survey on a series of large diameter transmission mains. The three pipelines were built in the 1960s and made of cement and steel, ranging in size from 1000 mm to 1200 mm.
