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.
- To improve fresh water use per employee by 5%
- 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 freshwater consumption by 20% over the following two years 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
Responsible Water Framework
The Responsible Water framework, developed in association with one of our water partners provides a set of quantitative and qualitative metrics that provide a wider framework which also evaluate aspects of campus design and people density, harvesting of endowed water (rainwater), embodied energy of different sources of water and aspects of knowledge, transparency and governance in campus management. An integrated framework like this helps consider and evaluate water decisions from economic as well as ecological contexts.
Two of the metrics are presented in the table below for four of our campuses.
- Responsible Siting (RS) is the freshwater demand that can be potentially met by rainwater. This metric is reflective of the rainfall endowment of the campus, campus design (with respect to harvestable surface water from rooftops) and the current/expected demand profile of the campus.
- Water Sustainability (WS) is amount of total demand met by rainfall and treated water.
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 impact any nationally or internationally designated water conservation areas.
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.
