Use of technology to reduce losses in Limeira (SP)

According to the 2018 Sanitation Ranking by the Trata Brasil Institute, which analyzes indicators related to the level of coverage, improvement of coverage and level of efficiency, in the provision of water and sewage services, Limeira ranked 6th, confirming its condition of reference of the latest rankings published by the Trata Brasil Institute.

BRK already has a series of technologies that innovate in use, treatment and loss reduction systems. Given that the topic of water is something that forms part of our core business, such solutions are multiplied above all in the search for operational efficiency.

Limeira was the first city to grant sanitation services to the private sector, in 1995. At the city's Water Treatment Station, approximately 21 million m³ of treated water are produced per year, with an average flow of 750 liters per second. From this point, the water is taken to the 100,000 connections, distributed over 1,200 km of water networks, to serve the approximately 300,000 inhabitants of the Municipality.

Among the best

According to the 2018 Sanitation Ranking by the Trata Brasil Institute, which analyzes indicators related to the level of coverage, improvement of coverage and level of efficiency, in the provision of water and sewage services, Limeira ranked 6th, confirming its condition of reference of the latest rankings published by the Trata Brasil Institute.

In addition to universalization and excellence in the provision of services, Limeira is also highlighted in the Trata Brasil Ranking for its efficiency in the distribution loss index, which considers the difference between the volume of water produced and the volume officially delivered. While, on average, Brazilian cities lose 43.18% of produced water, in Limeira this number is only 15.57%, the best mark in the country (SNIS – 2016).

This level of efficiency is possible with investments in people, equipment and management processes, to reduce real and commercial losses in the Municipality's water distribution system. Thus, Limeira has a sectorization of 70 macro-measurement zones where flows and supply pressures are controlled and measured, in addition to the maintenance of a park of water meters that are less than 5 years old. The Concessionaire has teams dedicated exclusively to detecting non-visible leaks, through the use of acoustic equipment, such as listening rods and electronic geophones.

Furthermore, the repair teams are equipped with remote programming tools that allow quick and qualified response to maintenance incidents in water pipes, making the average time elapsed between the discovery of a leak and the completion of the repair procedure shorter. less than 6 hours, avoiding wastage of water and ensuring regular supply to the population.

It is important to highlight the relevance of advances in actions to combat water losses in the distribution system, achieved over the more than 20 years of the Concession Contract. In addition to the universalization of water distribution and sewage collection and treatment systems, it appears that, currently, Limeira captures and treats around 15% less water than it did in 1995, even with almost double the number of interconnected water connections to the system. This is only possible due to the reduction in distribution water loss rates, which fell from 45% to 16%, avoiding the waste of around 5 billion liters per year, contributing to the quality of life in the municipality of Limeira and to the preservation of the sources of the Piracicaba River Basin.

These actions also allowed Limeira to go practically unscathed in relation to the water crisis in the State of SP, in the years 2014 and 2015. While most municipalities in the region had their homes' supply impacted by rationing regimes, Limeira did not experience any impact on water supply, maintaining the regularity and quality of water distributed to the population.

Replacement of networks in 2018

Since January, the concessionaire has already installed 4,529 meters of new water networks in the municipality. In total, nine new sections of networks were installed, benefiting around 48 thousand residents in 21 neighborhoods. This is a Plan to Combat Losses that has been carried out year after year by the concessionaire and which involves mapping the areas with the highest volume lost, streets with the highest occurrences of leaks and identifying the actions necessary to reduce these losses.
