Summary
Corporate
Information
Cycle
Accelerate the development agenda through sanitation (water and wastewater)
and society's awareness of the water cycle.
Operational efficiency and
loss management
Operational efficiency is an essential aspect of
achieving national universalization goals and
global objectives for water access and preservation,
with consequent mitigation of climate change.
By reducing losses, it is possible to produce less
water, which reduces energy consumption and the
addition of chemicals, having less impact on the
water sources.
The Água de Valor program seeks to increase
the efficiency of water distribution systems, in
addition to improving measurement and control
to meet the population's water supply needs
and guarantee this right to future generations. In
less than three years, the Água de Valor program
avoided an annual loss of 17.5 million m³, enough
to supply a city of 260 thousand inhabitants,
leaving our utility companies with losses lower
than the country's average.
The results of Água de Valor were materialized
in 2021 with the achievement of the 2020
Distribution Loss Rate (DLR) target. The volume
of water lost at the Group's utility companies
plummeted by more than 6 million cubic meters.
The program was given due prominence in 2021
in the Environmental Sanitation Operational
Efficiency Award, which is part of the National
Sanitation Quality Award (PNQS).

Petrópolis in the spotlight
While Brazil wastes, on average, 39.2% of all
the drinking water distributed, enough to
supply more than 63 million Brazilians in one
year, Petrópolis has a low loss rate, with 24.1%
of water losses in the 2021 distribution. In
relation to the rate per connection, the city
has a loss of 131 liters per day, well below
the standard established by the New Legal
Framework for Basic Sanitation of 216 liters.
The numbers are from an unprecedented
study by the Trata Brasil Institute, based on
public data from the National Sanitation
Information System (SNIS) for 2019. The city
ranks 1st among Rio de Janeiro's municipalities
and 7th nationally in relation to the loss rate.
With the implementation of the Água de Valor
Program in 2018, the utility intensified actions
to combat and reduce losses. In 2019, the
Hydraulic Modeling of the Petrópolis Water
Supply System was updated and served as
a guide for implementing Macrometers - an
instrument capable of measuring large flows.
These macrometers were placed in all Water
Treatment Plants (WTPs) and at strategic
points of the networks, creating the so-
called Districts of Measurement and Control
(DMCs). Thus, it is possible to establish the
management of pressures and flows in areas
of smaller coverage, making control easier.
