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 not only a conservation exercise—it is a practical engineering tool to control operating costs, reduce losses, and improve compliance. For most facilities, water usage is spread across multiple systems (process, utilities, domestic, cooling, landscaping and treatment). Without a verified water balance, hidden losses such as leakages, overflow, excessive backwash, incorrect metering and unaccounted reuse can remain unnoticed and continue for years.
A structured audit helps establish a baseline, identifies high-impact opportunities for reduction and reuse, and provides actionable recommendations that can be tracked through KPIs. It also supports statutory and stakeholder requirements where groundwater abstraction, discharge, or sustainability reporting is applicable. Elion’s approach focuses on measurable findings, clear prioritization, and implementation-ready recommendations—so the audit translates into real operational improvement.
A water audit is a systematic assessment of water inflow, distribution, usage, losses, reuse, and discharge within a facility or system. The objective of a water audit is to establish a detailed water balance, evaluate water use efficiency across processes, and identify opportunities for conservation, recycling, and optimization.
In industrial and commercial facilities, a water audit goes beyond documentation and includes physical inspection, flow measurement, process mapping, and evaluation of utility systems such as cooling towers, boilers, and effluent treatment plants.
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.
• Identification of 8–18% avoidable water losses, primarily due to leaks, unmetered usage, and process inefficiencies
• 5–15% optimisation potential in process and utility water consumption through operational improvements
• Preparation of a site-specific water balance highlighting reduction, reuse, and recycling opportunities
• Prioritised recommendations with practical implementation roadmap and monitoring approach
• Compliance-ready water audit report aligned with IS 10430, CGWA, and applicable SPCB requirements

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:
Clients receive:
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.
A structured report suitable for management, ESG and statutory review (as applicable to your facility requirements).
Water audits are recommended for:
The cost of a water audit depends on:
