We were hired to detect leaks, model, and district-meter the potable water network in the cities of Las Piedras and La Paz. Our goal was to provide CIEMSA with the necessary information to achieve the non-revenue water (NRW) reduction targets set by OSE.

Key Project Tasks

To accomplish this, we carried out the following activities:

• District Metering: We defined the intervention areas and established the actions required to hydraulically isolate them.
• Leak Detection: We used high-precision equipment such as pre-locators, correlators, and geophones to identify invisible leaks both in household connections and in the main pipelines.
• Hydraulic Modeling: We developed a hydraulic model in EPANET 2.0 and calibrated it for each district, which allowed us to better understand the network’s behavior.
• Support and Analysis: We accompanied CIEMSA during the implementation phase. We conducted inspections to detect irregular consumption and prepared intervention reports. We also determined the water balances in each district to measure the impact of the actions taken.

Project Outcome

Our work consisted of providing CIEMSA with detailed information on invisible leaks, based both on the current system model and on subsequent field detection. This enabled us to identify the works required to reduce non-revenue water in each district, meeting the leakage indicators established by OSE.

This project allowed us to contribute to a more efficient water resource management, reducing water losses and improving service in Las Piedras and La Paz.
