Targeted energy audit of the industrial water mains and distribution networks

Summary

In 2016 «Ostec-SMT» Company carried out a targeted energy audit of the drinking water supply networks at a wood processing plant in Siberia. The audit covered the water mains and distribution pipelines supplying water to the plant. The heart of the problem is the excess water losses (35% of the total water amount supplied by the public water supply system). The annual difference between the water amount purchased from the water services company and that supplied to the customers is 400 thousand m3. In order to locate the leaks it was decided to carry out consecutive measurements of drinking water flow from the interface of inventory responsibility, at the nodal points and at the service connections. The discovered water imbalance between the adjacent points, and leaks were determined with the use of a correlation leak detector. After the work completion the balance of the drinking water supply of the plant was compiled, the sections with losses were pointed out, and their quantitative estimate was given. The integrated study carried out by the experts of «Ostec-SMT» LLC provided for the exhaustive information on the state of the entire water supply system of the plant. The plant where the targeted energy audit of the water mains and distribution networks was carried out had implemented over the last years a number of large-scale investment projects, commissioned new and upgraded operating capacities.
