OUR VALUE CREATION | Natural capital
Water consumption is indispensable
for providing our services. Therefore, in
2021, we started the Water Efficiency
Project, which currently encompasses
6 units: Hospital Oeste D'Or, Hospital
São Rafael, Hospital Aliança, Hospital
Cárdio Pulmonar, Hospital Barra
D'Or and Hospital Rios D'Or. The
project's purpose is to reduce not
only water supply costs but also water
consumption, optimizing the units'
operation. The project Initiatives include
detecting leaks, installing more efficient
equipment (flow restrictors on faucets,
aerators, etc.), using water from wells
(when available), monitoring real-time
consumption and awareness-raising
campaigns for employees.
Hospital Norte D'Or, for example,
reduces water consumption every
month by setting up a system to
reuse the water from filters backflush
to irrigate the gardens. On the other
hand, Rios D'Or and Niterói D'Or use
the rainwater and HVAC condensation
water in their parking lot roofs and
ceilings. Units in the Federal District,
IFOR, Rios D'Or actually use aerators
for flow restriction in bathroom faucets,
while Hospital São Luiz São Caetano
harvest rainwater from roof gutters.
At the new unit Maternidade Star,
under construction in São Paulo (SP),
in addition to harvesting rainwater for
reuse, we chose materials that enable
reducing water consumption by up
to 90% and basins that allow using
up to 60% less water. We have also
reviewed the Maintenance department's
processes, with the purpose of providing
more speed in discovering and solving
possible problems, avoiding expenses
and waste.
Water used at the units comes from
three sources: concessionaires,
authorized artesian wells and water
tankers. All units, including those that
are not part of the Water Efficiency
project, rely on water management
carried out through utilities bills,
measurement equipment and
accounting for the water volume
received from water tankers during
the month. The units participating in
the Water efficiency project have a
more detailed monitoring from our
partner supplier.
In Brazilian regions where water
distribution, treatment and access are
a critical topic, such as the Northeast
region, and represent almost 25% of
total water consumption, Rede D'Or
São Luiz builds a Water Treatment Plant
(ETA in Portuguese), such as the case of
Hospital São Marcos (PE).
In 2021, total water consumption was 2,296.240 m³, down by 28% compared to
2020, due to the water efficiency initiatives implemented by the company. GRI 303-5
