OpenFlows WaterGEMS Saves Sabesp BRL 365,000 per Month on Diadema’s Water Treated Volume Costs - 1

CASE STUDY Project Summary Organization Sabesp – Companhia de Saneamento Básico do Estado de São Paulo Solution Water, Wastewater, and Stormwater Networks Location Diadema, São Paulo, Brazil Project Objectives • To enhance customer satisfaction by limiting water supply outages in the city of Diadema, Brazil. • To ensure consistent water supply at high points in the sector and disadvantaged supply points in the water network. Products Used: OpenFlows™ WaterGEMS® Fast Facts • The Regional Management Unit at Sabesp Metropolitana Sul sought to use hydraulic modeling, high precision meters, and process integration on this project. • Hydraulic modeling and simulation were conducted in OpenFlows WaterGEMS, which identified and corrected network inconsistencies. ROI • Sabesp reduced water loss from 41% to 32% by utilizing hydraulic models. • The return on investment will be recovered for the organization within 14 months as a result of the optimized network and consistent supply. • Approximately BRL 365,000 will be recovered per month due to the reduction in water loss and recovery of lost volume.

Supplying water to 28.8 million people and treating and collecting sewage for 23.2 million people, Sabesp – Companhia de Saneamento Básico do Estado de São Paulo provides water and collects and treats sewage for 366 cities in the state of São Paulo, Brazil. The Regional Management Unit at Sabesp Metropolitana Sul (MS) took on a project to highlight the significance of using process integration and new technologies, including hydraulic modeling and high precision meters. The BRL 5.12 billion project involved enhancing the water supply network to limit supply outages and improve customer satisfaction in the region. Updating the network to improve operating pressures within the entire sector would ensure continual water supply to all residents in this thriving metropolitan area of Brazil. Older System Presents Operational Challenges Before this project began, the city of Diadema was dependent on a single pipeline that supplied water to the main reservoir of the water system. From the main reservoir, another pipeline branched out to supply a second reservoir, and a pipeline then branched out from the second reservoir and connected to a third reservoir. This tiered configuration of reservoirs posed a problem for the water network because it caused supply outages. Furthermore, when there was an issue in the pipeline that prompted a water supply outage, recovery time was extremely slow, leading to consumer dissatisfaction. In 2016, Sabesp invested money into setting up new pipeline connections, with each reservoir being fed by its own independent pipeline. Because of this new design setup, the old pipelines that connected the reservoirs became obsolete and were no longer used. At the same time, however, the configuration of the distribution system was still unreliable. Due to high volumes of consumption, the output of water to supply approximately 49,000 connections included the use of a single 500-milimeter loop and pipes that were subjected to critical operating loads at high speeds. Consequently, there were high loss loads in the distribution system that prompted supply outages, mostly at the highest points in the sector, which are portions of the system that are located at disadvantaged supply points or on areas of elevated ground. Developing a New Solution To overcome these challenges, Sabesp engineers analyzed the system layout and sought to resolve the flow limitation issue. The engineers decided to construct another 800-milimeter diameter output loop that was capable of supplying the required volume of water for consumption in the sector; this would resolve supply issues. Yet, there were significant challenges when implementing this solution, including the high expense due to the size of the undertaking, which included labor and materials. Additionally, it was difficult for the engineers to identify the optimal route and location for such a wide pipe. To resolve this problem, the project team decided to extend the 400-milimeter network by 150 meters at the beginning of 2017. Then, a pressure-reducing valve was installed to facilitate the automated remote control of supply. After the work was completed, the water supply was monitored, and checks were performed to ensure that intermittent water supply problems at high elevations were eliminated. Lastly, the original pipeline network was included within the distribution network to fully resolve water outages. All updates implemented during the first phase of construction improved the water supply t
