WATER DISTRIBUTION SYSTEM MODELING FOR A TOWN WITH 10 000 INHABITANTS
Abstract
This study presents the evolution of residual chlorine concentration in the water distribution network for a town with 10 000 inhabitants. The distribution system consists of a tank, pump station, 41 loops, 175 junctions and 166 pipes. The paper presents also a methodology for computing the residual chlorine concentration decay in water distribution system, over a 7 days period of time. Chlorine is injected at the tank, with a constant concentration of 0.5 mg/l. A variable water demand over a 168 hours period is implemented with a one hour flow pattern time step. The hydraulic time step is set to 1 minute, while the water quality time step is set to 0.02 minute, to ensure predicting accurate instantaneous chlorine concentrations. Modeling and data processing was performed for two scenarios. In the first scenario the distribution system network modeling it was done having Q = 45 l / s. In the second scenario the distribution system network modeling it was done having Q = 37 l/s. In both scenarios the length of distribution system is 62 km. Hydraulic and Water Quality analysis is performed with EPANET program.
