Elion provides Water Audit services for industrial, commercial and institutional facilities to assess water consumption, losses, reuse and compliance in line with applicable Indian standards.
A Water Audit is a systematic and detailed assessment of water consumption, distribution, losses, and efficiency within a facility, building, or industrial process. It involves measuring and analyzing how water is sourced, used, reused, and discharged to identify inefficiencies, leakages, excessive consumption, and opportunities for conservation, cost reduction, and sustainable water management.
A Water Audit is carried out by systematically analyzing how water is sourced, used, distributed, reused, and discharged within a facility. The process starts with a review of water bills, operational data, and existing layouts to understand overall water consumption patterns. This is followed by a site inspection to identify water intake points, storage systems, major usage areas, and discharge locations.
Water consumption is then measured using installed meters or portable flow measurement instruments, and where metering is unavailable, standard estimation methods are applied. Based on the collected data, a water balance is prepared to compare total water input with actual usage and losses. This helps identify leakages, excessive consumption, inefficiencies, and potential areas for water conservation.
Elion is an engineering and consulting organization providing professional water audit services through qualified engineers with experience in industrial utilities, water systems, and sustainability assessments. Our audits are conducted using physical site verification, flow measurements, and engineering calculations to ensure factual accuracy and real-world applicability. Elion’s water audits are suitable for regulatory compliance, operational improvement, and ESG disclosures.

The following process is followed to ensure the audit results are measurable, practical and suitable for compliance and management review.
Collect water bills, source details (municipal/ borewell/ tanker), STP/ETP logs, drawings, and process/utility consumption data.
Map sources, storage, distribution networks and end-use points to define audit boundaries and critical nodes.
Validate physical conditions, identify leak/overflow risks, verify operating practices, and confirm actual usage patterns.
Verify metering adequacy; perform flow checks/spot measurements where required to validate key consumption streams.
Prepare a source-to-discharge water balance, quantify losses/unaccounted consumption, and establish baseline KPIs.
Identify conservation, reuse/recycling, process optimization and monitoring opportunities with feasibility considerations.
Review applicable CGWA/SPCB/CPCB requirements (where applicable) and suggest controls, documentation and monitoring approach.
Collect water bills, source details (municipal/ borewell/ tanker), STP/ETP logs, drawings, and process/utility consumption data.
A professional water audit includes:
Water audits are increasingly important due to regulatory requirements, water scarcity, rising utility costs, and ESG expectations. A structured water audit enables organizations to understand actual water performance rather than relying solely on billing or estimated data.
Common drivers for conducting a water audit include:
Water audits support compliance and reporting under multiple frameworks, including:
The water audit process typically involves:
Elion’s water audit scope typically covers:
Ultrasonic / Electromagnetic Flow Meters for accurate measurement of water flow in pipelines and processes.
Portable Water Flow Meters to assess water usage where permanent meters are not installed.
Pressure Gauges to analyze distribution pressure, identify leakages, and assess system performance.
Digital Water Meters to monitor consumption, trends, and baseline water usage.
Water Quality Testing Instruments to evaluate water characteristics and reuse or recycling potential.
Water Level Sensors / Level Indicators to monitor storage tanks, sumps, and inflow–outflow balance
Source-to-discharge mapping and a documented water balance identifying major consumers and loss points.
Recommendations to improve measurement points, KPIs and routine tracking for sustained performance improvement.
Prioritized opportunities for reduction, reuse/recycling and operational controls with practical implementation focus.
