We believe that water is a critical resource which should
be preserved. We contribute to the cause, with our
sustainable water management solutions. To effectively
manage its water footprint, L&T undertook initiatives
like creating zero wastewater discharge campuses,
water conservation, recharging underground aquifers
through rain water harvesting, community watershed
programmes, and water footprint assessment.
State-of-the-art wastewater treatment systems have been
installed at all our campuses and treated wastewater
is re-used within the campuses for gardening, toilet
flushing and cooling tower applications, thereby reducing
fresh water consumption. Water storage structures like
check dams, ponds and anicuts are built by the Company
for the communities around its facilities. The subsequent
increase in water storage and ground water recharge,
helped communities gain improved access to water for
drinking and agriculture.
All 24 L&T Campuses across India achieved Water
Positive Status in 2016.
Keeping tabs on water consumption
We account for the water footprint of the Company
with water credit and debit calculations. Water debit is
calculated as the fresh water consumed by the campuses
and water credits include rain water harvested, water
stored in check dams, water recycled and reused. The
Water Positive status is conferred upon a manufacturing
location, only when the amount of water withdrawn for
industrial usage is less than the amount of water given
back to society and nature.
The water harvesting structures developed by L&T
in Maharashtra, Madhya Pradesh, Tamil Nadu and
Rajasthan, have accumulated more than 2,400 million
litres annually
Check Dam Constructed at Maharashtra
L&T also harvested 408 million litres
of water at its various establishments. This brings the
total water credit (returned to society and nature) to
4,125 million litres, whereas the water utilised or water
debit was at 3,900 million litres. Water positivity of
manufacturing campuses was affirmed on the principles
of completeness, reliability and accuracy by DNV GL
Business Assurance India Pvt. Ltd. – an independent
certification agency.
Water positivity of all L&T campuses is a key initiative
taken in L&T’s Sustainability Roadmap 2021. The water
positive status reaffirms the Company’s commitment and
rigour towards water efficiency as part of its corporate
sustainability programme.
