At Wipro, we view water from the three inter-related lens of Conservation, Responsibility and Security; our articulated goals are therefore predicated on these three dimensions.
- Water efficiency - Continuously improve water efficiency (fresh water use per employee) of our operations.
- Responsible Sourcing - To ensure responsible sourcing and water management in proximate communities, especially in locations that are prone to water scarcity.
- Water security - Recognizing water availability as a business risk, to proactively assess and plan for the water security of the organization in a manner that is congruent with the first two objectives.
- Improve water efficiency (fresh water use per employee) by 5% year on year
- Reduce absolute water consumption in existing campuses by 20% between FY16 and FY21
- Responsible stewardship: To ensure responsible water management in proximate communities, especially in locations that are prone to water scarcity
The following sections describe our implementation approach and the initiatives in this context.
We launched a program in 2013 with the aim of minimizing absolute freshwater consumption by 20% by FY2018-19 through an integrated approach as articulated below:
- Implementing standard metering infrastructure and procedures across campuses.
- Demand side optimization (improving efficiency through flow restrictors across campuses and arresting leakages).
- Improving recycling levels through ultra-filtration with eventual use for non-contact applications other than landscaping and sanitation.
- Integrating rain water harvesting into the consumption side of the campus water cycle.
- Improving water governance by building user awareness and involvement of water plumbers.
We are working towards making our facilities more and more water –sustainable. This has been achieved with the use of water efficient fixtures, waste water treatment technologies, rain water harvesting and smart metering for monitoring.
Aerators: we have installed Aerators in all our wash basins across the campuses during the last fiscal year 2015-16. Aerators provide a constant flow rate of 0.5 GPM through variable pressure optimizing water use to great extent.
Water less urinals: We have retrofitted existing urinal system with water less urinal system by installing key valves in some of the locations. This system doesn’t require water for flushing. This in turn has reduced water consumption and energy related to pumping of the system.
Smart water metering: We have installed smart water meters in our campuses to ensure continuous monitoring of water consumption data in real time. These smart meters have enabled us to identify wasteage areas so that immediate action can be taken.
Waste water reuse: Entire waste water generated in the campus is treated at our sewage treatment plants. Recycled water is used for landscaping and flushing. We have installed Ultrafiltration and Reverse osmosis in three of our major locations and reusing the treated water for cooling systems, this has reduced our fresh water consumption by 40%. The water quality is monitored on a regular basis ensuring standards and safety of the employees.
Nanofiltration: Conventional water softeners is being replaced by membrane softeners (Nanofiltration) which gives good quality softened water. Nanofiltration removes nearly all viruses, most of the natural organic matter and a range of salts. Nanofiltration removes divalent ions, which make water hard, so it is used to soften hard water.
Rain water Harvesting: Rainwater harvesting and integration into freshwater use is a significant improvement area for water sustainability across our campuses. We plan to integrate rain water use into primary freshwater use cycle across identified large campuses over the next two year period. Presently rain water constitutes 2% of the total fresh water.
Employee Participation: We are encouraging employee to participate and share their view on the sensitive issues like water and waste. We celebrate world water day along with the employees.
Ground water, municipal water supplies and private purchase contribute to nearly 99% of the total fresh water consumption. The water supplied by the municipal bodies and the industrial association are sourced by them in turn from river or lake systems. Water that is purchased from private sources can be traced to have been extracted from local aquifers.
We take care not to withdraw water from water bodies that are recognized to be particularly sensitive due to their relative size, function, or status as a support source for endangered species. None of our operations are significantly impacted by our withdrawal or are covered under any nationally or internationally designated water conservation areas. At three of our locations (Bengaluru, Chennai and NCR) we are predominantly dependent on private sourcing of water supply through tankers, which in turn draw from local aquifers. During summer periods, our sourcing could be impacted due to shortages or community concerns. We also have quality issues (high TDS), which results in treatment costs. http://kswn.in
34 of our 59 locations in India are leased and located in prime city areas. For these locations, waste water is discharged to CSTP’s (Common Sewage Treatment plants) and to the municipal sewerage systems. We take care not to discharge waste water into any subsurface waters, surface waters or sewers that lead directly to rivers, oceans, lakes, wetlands, and ground water. The treated water from our sewage treatment plants are tested and are in conformance with the parameters specified by the respective local pollution control boards.
