Abstract

The water supply infrastructure is being under an ample process of reconstruction in Dobrogea. Our study focuses on the drinkable water supply system in a village of about 1000 inhabitants, situated in Southern Dobrogea. The system is fed by groundwater pumped from a single well and stored in a reservoir. The water flows by gravity through the distribution network. Specific for this system is the position of the source, which is placed in the middle of the village where the terrain elevation is the lowest. The network is mainly branched and it has about 15 m of pipe per inhabitant. The terrain elevation varies from 44.14 m to 124.26 m. The design water demand of one consumer on the external network is up to 0.06 l/s. The numerical simulation allows the engineers to get a whole image of either building and operation possibilities of a drinkable water supply system. The numerical simulation developed in EPANET pointed out the optimal configuration of the system, the hydraulic parameters, and the energy consumption. The velocity field obtained by simulation shows links where the velocity is low and the water quality is affected. The paper proposes different alternative for the operation optimization of the network, in compliance with the technical requirements.
