Water Stewardship & BRSR: How to Report & Improve Your Water Footprint

Introduction

Water has emerged as one of the most critical indicators in BRSR reporting India, reflecting both environmental responsibility and operational efficiency. It is a resource that directly impacts business continuity, regulatory compliance, and community relationships. Yet, despite its importance, water remains one of the most mismanaged aspects of corporate sustainability. Many organizations still lack visibility into how much water they consume, where it is sourced from, and how efficiently it is used or reused. This gap not only affects reporting accuracy but also leads to unnecessary wastage and higher operational costs.

As ESG compliance for businesses becomes more data-driven, water stewardship is no longer optional, it is a strategic priority. Regulators and stakeholders expect companies to go beyond basic disclosures and demonstrate active efforts to reduce their water footprint. Effective water management not only strengthens BRSR performance but also enhances resilience against water scarcity, which is becoming an increasing concern across industries. Companies that take a proactive approach to water stewardship are better positioned to meet evolving SEBI sustainability guidelines while building long-term sustainability credibility.

What BRSR Requires for Water Reporting

BRSR mandates a comprehensive and transparent approach to water reporting, requiring businesses to track and disclose detailed metrics that reflect their actual water usage and management practices.

Total Water Consumption : Companies must report the total volume of water consumed across all operations. This includes water used in processes, sanitation, cooling systems, and other operational activities. Accurate measurement is essential, as it forms the baseline for identifying inefficiencies and setting reduction targets. Without a clear understanding of total consumption, it becomes difficult to implement meaningful conservation strategies.

Source-Wise Usage: Organizations are required to break down their water consumption based on sources such as groundwater, municipal supply, surface water, or tanker water. This level of detail helps stakeholders assess the sustainability of water sourcing practices. Over-reliance on groundwater, for instance, may indicate higher environmental risk, while diversified and sustainable sourcing reflects better resource management.

Recycling & Reuse Data: BRSR also emphasizes the importance of circular water management by requiring companies to disclose how much water is treated, recycled, and reused within their operations. This includes data from sewage treatment plants (STPs), greywater systems, and other recycling mechanisms. Higher reuse rates indicate efficient water stewardship and reduced dependency on fresh water sources, which significantly improves ESG performance.

Common Challenges in Water Management

Even with clear BRSR reporting requirements, many organizations struggle to manage water efficiently due to gaps in infrastructure and monitoring. One of the most common issues is the absence of sub-metering. Without sub-meters installed across different areas or processes, companies can only track total water consumption at a building level. This makes it nearly impossible to identify where water is being overused or wasted, limiting the ability to take targeted corrective action.

Inaccurate tracking further complicates the problem. Manual data collection, irregular readings, and lack of standardized measurement systems often result in unreliable data. This not only affects the credibility of BRSR disclosures but also prevents businesses from setting realistic reduction goals. Additionally, significant water wastage occurs through inefficient fixtures such as conventional urinals, leaking pipelines, and outdated plumbing systems. These seemingly small inefficiencies can add up to massive annual losses, increasing both operational costs and environmental impact.

How to Improve Water Performance

1. Audit Your Water Usage

The first and most critical step toward improving water performance is conducting a comprehensive water audit. This involves mapping out how water flows through your facility and identifying key consumption points. Without this clarity, any attempt to reduce usage becomes guesswork rather than a data-driven strategy. A detailed audit provides actionable insights that form the foundation of effective water stewardship.

Start by identifying major consumption areas within your operations. Restroom usage is often one of the highest contributors, especially in commercial spaces with high footfall. Fixtures such as flush systems and urinals can consume large volumes of water daily if not optimized. Cooling systems are another major area, particularly in large buildings or industrial setups where HVAC systems rely heavily on water for heat exchange. Process water, used in manufacturing or operational activities, also needs close monitoring, as inefficiencies here can significantly increase overall consumption.

By breaking down water usage across these categories, businesses can pinpoint inefficiencies and prioritize interventions. This structured approach not only improves operational efficiency but also strengthens BRSR reporting by ensuring that water data is accurate, measurable, and aligned with ESG compliance goals.

2. Eliminate Waste at Source

Once water usage patterns are clearly understood, the next step is to address inefficiencies at their origin. A significant portion of water loss in commercial and industrial facilities comes from outdated infrastructure and unnoticed wastage. Traditional urinals, for instance, consume thousands of litres of water annually per unit, especially in high-traffic areas. Over time, this results in an enormous and often unnecessary burden on both water resources and utility costs.

Leakages are another silent contributor to water loss. Small drips from pipelines, faulty flush systems, or worn-out fittings may seem insignificant on a daily basis, but they accumulate into substantial wastage over months. The challenge is that these leaks often go undetected without proper monitoring systems in place. Eliminating waste at the source requires a proactive approach , upgrading fixtures, conducting regular maintenance checks, and implementing systems that prevent wastage rather than reacting to it after it occurs.

3. Adopt Water-Saving Technologies

Beyond eliminating inefficiencies, businesses must actively invest in technologies that reduce dependence on fresh water. Waterless sanitation solutions are one of the most effective ways to cut down water usage in restrooms, significantly lowering consumption without compromising hygiene. These systems not only conserve water but also reduce maintenance requirements and operational costs over time.

Greywater reuse is another critical strategy, allowing water from sinks, showers, or other non-industrial processes to be treated and reused for applications such as flushing or landscaping. This reduces the demand for fresh water while improving overall water efficiency. Additionally, optimizing Sewage Treatment Plants (STPs) ensures that wastewater is treated effectively and reused wherever possible. A well-functioning STP improves recycling rates, enhances water quality, and supports compliance with BRSR reporting requirements.

By integrating these technologies, organizations can transition from a linear “use-and-dispose” model to a circular water management system. This not only strengthens sustainability performance but also aligns closely with long-term ESG goals.
