Pilot project for the athens water supply network upgrading and leakage control

EYDAP implemented a leakage level assessment and detection project for the water distribution network of Athens (with population of over 3,800,000 inhabitants). The overall project consisted of 12 parallel pilot projects in selected parts of the water supply distribution network of Athens. This pilot project for leakage control on the water supply system of Athens covered the areas of Glyfada, Argyroypoli, Elliniko, Voyla and Vari covering about 225 km of pipes. Total project was separated in two phases: INITIAL PHASE: The pilot project area initial field survey covered for map updating and appurtenance operational condition assessment and repair. Also: i. Water quality upgrade works, ii. Hydraulic model development, iii. Consumption data evaluation iv. Zone and sub-zone boundary proposal with BoQ or needed works including new pipes and valves, permanent and portable flow and pressure equipment installation works. SECOND PHASE (LEAKAGE DETECTION AND WATER QUALITY): i. Night pressure test to verify the water tightness of the delineated zone boundaries, ii. Sub-zone minimum night flow measurement and leakage flow rate estimation, iii. Active leakage control activities in the sub-zones with the higher leakage rate (using sounding and acoustic correlation components), iv. Water quality field survey to verify the effectiveness of the relative proposed works.
