W sytuacji ciągłego zmniejszania się poborów wody, utrzymanie odpowiedniej jakości wody w sieci staje się coraz trudniejsze. Najbardziej rozpowszechnioną metodą usuwania zdeponowanych zanieczyszczeń w rurociągach jest płukanie upustowe wykorzystujące hydranty pożarowe. Planowanie efektywnej sekwencji następujących po sobie płukań możliwe jest przy wykorzystaniu modeli komputerowych sieci wodociągowych. W pracy zbudowano model sieci wodociągowej miasta Poddębice w programie EPANET 2. Opracowany model skalibrowano w oparciu o zapisy produkcji i zużycia wody oraz pomiary ciśnień w kilkunastu punktach sieci. Ciśnienia zmierzono w trakcie upustów wody przez hydranty. Przeprowadzono symulację płukania wybranego odcinka sieci. W wyniku symulacji wyznaczono chwilowe wartości prędkości przepływu wody i według przyjętego kryterium wyznaczono zasięgi płukań. Kryterium wyznaczono w oparciuo zależność opisującą ruch cząstek zanieczyszczeń uwzględniający mechanizmy turboforezy i turbulentnej dyfuzji. Ponadto przeanalizowano różne warianty realizowania następujących po sobie płukań oraz wybrano wariant optymalny.

In the case of the continuous decrease in consumption of water, maintaining water quality in the network becomes increasingly difficult. The most common method of removing deposited particles in pipelines is flushing hydrants using relief. Planning an efficient sequence of successive rinses is possible with the use of computer models of water supply network. For this purpose, the model of water supply network of the city Poddębice was created in Epanet 2. The model was calibrated based on the records of production and consumption of water and pressure measurements at several points in the network. Pressure was measured during water hydrants discounts. Then the simulation of flushing the network section was performed. As a result of the simulation was set instantaneous velocity of water flow, and according to accepted criteria set ranges rinses. The criterion determined based on the dependence that describes the motion of the particles pollutants taking into account the mechanisms of turbophoresis and turbulent diffusion. Also analyzed different variants of consecutive rinses and selected the optimal variant.
