PPP Sewage
This municipality, with a population of about
408 thousand people, has stood out nation-
ally for its improvements in operation and
its results concerning sustainability. Re-
sponsible for sewage collection and treat-
ment services, the concessionaire Águas
do Mirante, of the Aegea Group, began to
reuse the sludge remaining from the sew-
age treatment as fertilizer. The significant
investment in the operation includes the
time dedicated to research and innovation
to make it possible to use the materials in
agriculture. The project has the participa-
tion of the campus of the Luiz de Queiroz
School of Agriculture (Esalg), part of the
University of São Paulo (USP).
About 900 tonnes of sludge, collected in
the city's STPs, are taken to a kind of green-
house for drying. In less than a month, the
residue decreases by three times its initial
volume, thus presenting a soil aspect. This
is when it is ready to be used as fertilizer for
agriculture as it has large concentrations of
nutrients. The project is considered as be-
process, the effluents are released into riv-
ers with up to 85% purity in relation to the
initial organic load.
Currently, the concessionaire manages ten
biodigesters, which guarantees reuse of a
total of 280,000 plastic bottles and almost
three thousand tyres.
ing highly beneficial to the environment. Be-
fore the operation, all the sludge from the
stations would be taken to the landfill.
Another important change to assure the
rates of sewage service and improvement
to the population's quality of life has been
the implementation of collection networks
in communities located in regions that are
not part of the concession. This action has
been carried out since 2017. Since then,
more than 10 kilometers of networks have
been installed. Thirteen communities, with
2,000 families, have benefited.
Resende (RJ)
Full Concession
Developed by the Águas do Brasil Group,
the Olhar Ambiental programme enables
the planning and management of environ-
mental education actions carried out by
the holding and its concessionaires. The
project has benefited about 170,000 people
since its implementation, in 2014.
In 2020, the programme reached out
to 1,853 people by adapting some of the
proposed activities, to ensure the safety of
participants and the teams involved, faced
with the Covid-19 pandemic.
In Resende, the Águas das Agulhas Negras,
which belongs to the Group, is one of the
concessionaires that has contributed most
to the programme, by serving people during
activities within technical activities to water
and sewage treatment plants, workshops
and socio-environmental events.
With the current pandemic scenario, the
concessionaire has made a virtual tour of
WTP Alegria available, through the Olhar
Ambiental 360° project. The project allows
a fully immersive experience in virtual real-
ity, leading the visitor to know all the pro-
cesses used in treatment of water.
