PANORAMA OF THE PRIVATE SECTOR'S PARTICIPATION IN SANITATION 2021
A NEW SOCIAL AND ECONOMIC FRONTIER FOR BRAZIL
Cachoeiro de Itapemirim
(ES)
Full Concession
This is one of the first municipalities in the
country to assign the management of water
and sewage services to the private sector,
in 1998. Since the beginning of the conces-
sion, over BRL 429 million have been invest-
ed in works, expansion, improvements and
modernization of services. Today, the city is
below the national average of losses, with
22.51%. Before the concession, the cover-
age of the treated water network in the urban
area was 87%, while losses exceeded 56%.
Only 5% of the houses in the urban area had
sanitary sewage systems. The sewage treat-
ment system was non-existent, while some
21 million liters of sewage were poured into
the Itapemirim River every day.
Today, some 193,000 inhabitants in the ur-
ban area of the municipality have sewage
collection service. Of the total sewage col-
lected, 98.15% is treated. The treated water
supply reaches 100% of urban homes.
Through a new amendment to the conces-
sion contract, valid from May 2019, BRK
Ambiental began to serve communities out-
side the urban perimeter. Until then, these
communities did not have water supply
services, water being supplied exclusive-
ly by water tankers. In total, 24 kilometers
of water and sewage networks were built
to connect these communities with public
sewage lines.
In 2012, the concessionaire made itself
self-sustaining in energy after the con-
struction of the Small Hydro Power Plant
-
PCH Ilha da Luz at WTP João Goulart,
ensuring the system's energy and opera-
tional efficiency.
The concessionaire maintains a new in-
vestment programme, which began in
2018 and will run until 2022, providing for
the modernization and expansion of the
water supply and sanitary sewer systems
in all neighborhoods and districts of the
municipality, the total investment coming
to BRL 30 million. This March, it was re-
certified based on the standards and re-
quirements of: ISO 14001:2015 (Environ-
mental Management Systems) and ISO
9001:2015 (Quality Management System)
for a new three-year cycle, in addition to
being certified to ISO 45001:2018 (Inter-
national Standard for Occupational Health
and Safety Management System) which
focuses on improving performance in
terms of Occupational Health and Safety.
Ribeirão Preto (SP)
Sewage Concession
In 1995, sewage concessionaire GS Inima
Ambient became the manager of sewage
treatment in the city that, at the time, had
450,000 inhabitants (and just 2% of domes-
tic sewage treatment, through a treatment
pond in the district of Bonfim Paulista).
With a current population of about 700 thou-
sand and with a sewage network covering
98% of the municipality, Ribeirão Preto is in
two different rankings of best cities for san-
itation in Brazil: that of the ABES and that
of the 'Trata Brasil' Institute. With the uni-
versalization of sewage treatment, the con-
cessionaire also ensured the clean-up of the
Pardo River watershed. The company is re-
sponsible for the revitalization of waterways
in the region, which, until 2002, received dis-
charge volumes equivalent to a daily load of
27 tonnes of raw organic matter.
In 2011, the concessionaire also became the
first company in the country to implement
a biogas power generation system using
sludge from the sewage treatment process.
The project is doubly ecological because
it also extracts biogas to be burnt as fuel.
This prevents direct emission into the at-
mosphere, thereby minimizing the emis-
sion of greenhouse gases. It is a renewable,
clean and responsible source of energy,
which accounts for some 60% of the ener-
gy needed for the operation of the sewage
treatment plant. The daily volume of biogas
comes to about 7,000 m3, which allows
the production of 15,000 kWh/day, thereby
making sure of the energy efficiency of STP
Ribeirão Preto.
