A Family-Owned Company on a Mission to Ensure Access to Water and Sanitation for All

TSA – Tecnologia em Saneamento Ambiental (which translates to Technology in Environmental Sanitation in English) has a passion for the betterment of the communities they serve. TSA’s headquarters are in Porto Alegre, in the state of Rio Grande do Sul in Brazil, but they also work on projects that support cities across the southernmost part of the state. This family-owned business focuses on designing resilient and efficient water and wastewater networks. Engineers JosĆ© Vilmar Viegas and Matheus Viegas —a father-son team—and a handful of other employees work hard to bring a better quality of life to underserved communities. Their goal is to design water infrastructure that will grant access to water and sanitation services and improve water networks. These projects are key to social and economic development and that is what drives JosĆ© Vilmar and Mathues to do this work. Connected Data Brings Real-World Impact In Brazil, the most vulnerable communities lack access to water and sanitation systems.

One Hydrant vs. Two Hydrant Flow Test

Pretty much everyone who has worked in water distribution has been involved with hydrant flow testing at one time or another. It’s not very difficult. Place a pressure gauge on a residual hydrant and flow a nearby hydrant while recording the hydrant flow and the pressure at the residual hydrant with no flow and with flow. The procedure is documented in many places (AWWA, 2016).
