Water Audit Methodology
Engineering-Led Water Management & Conservation
At SARK Engineers & Consultants, our water audit methodology is designed to help industrial and institutional facilities optimize water usage, reduce freshwater dependency, improve reuse, and ensure regulatory compliance.
Our approach combines on-site engineering assessment, structured water balance analysis, and AI-assisted decision support—used strictly under expert supervision—to deliver practical, implementable water conservation solutions.
How We Work
Audit Objective & Boundary Definition
The audit begins with a clear definition of objectives, system boundaries, and compliance requirements.
This includes:
-
Understanding process and utility water requirements
-
Identifying freshwater intake, reuse, and discharge points
-
Defining audit scope (process, utilities, domestic, gardening)
-
Alignment with statutory and sustainability goals
Outcome:
A documented audit scope with defined water performance objectives.
Performance Benchmarking & Gap Analysis
Water usage is benchmarked against:
-
Industry best practices
-
Applicable regulatory norms
-
Specific water consumption targets
Benchmarking covers:
-
Freshwater consumption per unit output
-
Reuse and recycle ratios
-
Effluent generation and discharge norms
Outcome:
Quantified gaps and prioritised opportunities for improvement.
Reporting & Documentation
We deliver clear, regulator-ready documentation.
Deliverables include:
-
Detailed water audit report
-
Executive summary for management
-
Water balance diagrams and calculations
-
Compliance support documentation
AI-assisted reporting tools improve clarity and turnaround time, with full engineering review and accountability.
Outcome:
Reports that support approvals and implementation.
On-Site Assessment & Data Collection
Detailed on-site assessments are conducted to capture actual water flows and operating practices.
Activities include:
-
Inspection of intake, storage, distribution, and discharge systems
-
Measurement of flow rates and consumption patterns
-
Review of operating practices and housekeeping
-
Verification of meters, logs, and drawings
Outcome:
Reliable, ground-truth water consumption and discharge data.
Identification of Water Conservation Measures (WCMs)
Based on analysis, Water Conservation Measures (WCMs) are identified.
Typical measures include:
-
Process optimisation and control improvements
-
Leak detection and housekeeping improvements
-
Reuse and recycle enhancement
-
Segregation of streams for targeted treatment
Each measure is evaluated for:
-
Water savings potential
-
CAPEX and OPEX impact
-
Implementation feasibility and risk
Outcome:
A structured, actionable list of water-saving opportunities.
Implementation Support & Post-Audit Review
Where required, we support implementation and performance verification.
Support includes:
-
Technical clarifications during execution
-
Post-implementation water balance review
-
Fine-tuning of operational practices
Outcome:
Sustained water efficiency and compliance.
Water Balance Development & Validation
Collected data is structured into system-wise and plant-level water balances.
This stage includes:
-
Preparation of detailed water balance diagrams
-
Validation of data against production and operating hours
-
Identification of losses, leaks, and inefficiencies
AI-assisted analytical tools may be used to:
-
Detect abnormal consumption patterns
-
Identify data inconsistencies
-
Compare multiple operating scenarios efficiently
Outcome:
Clear visibility into water inflows, usage, reuse, and discharge.
Techno-Economic & Feasibility Analysis
Recommended measures undergo detailed techno-economic evaluation.
This includes:
-
Water and cost savings estimation
-
Payback and lifecycle cost analysis
-
Sensitivity analysis for load and seasonal variation
-
Alignment with regulatory and operational constraints
AI-assisted scenario modelling may be used for faster comparison; final recommendations are engineer-validated.
Outcome:
Decision-ready conservation strategies.
Key Principles of Our Water Audit Approach
-
Engineering judgement drives every recommendation
-
AI supports analysis, not decision ownership
-
Compliance and practicality are non-negotiable
-
Focus on measurable water savings and reuse
Proven at Scale
