Water Audit Services

Water is rapidly becoming one of India’s most constrained industrial inputs. Rising municipal tariffs, declining groundwater tables, tightening discharge regulations, and growing ESG reporting requirements are forcing organisations to treat water not just as a utility — but as a strategic resource to be measured, managed, and conserved. Bigeta Energy Solutions delivers comprehensive water audit services across India, helping manufacturing plants, commercial buildings, hospitals, and institutions identify hidden inefficiencies, fix leaks, optimise water- intensive processes, and build a sustainable water management strategy.

What Is a Water Audit?

A water audit is a systematic, measurement-based assessment of how water enters, flows through, and leaves an organisation’s premises. It covers every point of water use — from mains supply metering and internal distribution to process consumption, cooling systems, sanitation, and wastewater discharge. The audit quantifies water losses, identifies opportunities for recycling and reuse, and benchmarks performance against industry norms and regulatory requirements. For Indian industries — where water costs are rising 10–15% annually in major industrial belts and groundwater licences are becoming harder to obtain — a water audit is no longer a sustainability exercise. It is a business imperative. A properly conducted water audit typically identifies savings of 20–40% of current water consumption, with many conservation measures having a payback period of less than 12 months.

What Our Water Audit Covers — Six Key Assessment Areas

Key Benefits of a Water Audit

Direct Water Cost Reduction

Identify leaks, over-use, and inefficient practices. Typical savings of 20–35% of current water procurement costs, including reduced tanker deliveries and borewell pumping costs.

Regulatory Compliance

Meet CGWB, PCB, and state groundwater board requirements. Support ZLD compliance for industries in water-stressed zones. Align with CPCB effluent discharge standards.

ESG & Sustainability Goals

Water consumption and intensity metrics are key ESG KPIs. Audit findings feed directly into GRI, CDP, and BRSR sustainability reporting and support net-zero water ambitions.

Reduced Wastewater Costs

Identify recycling and reuse opportunities that reduce effluent volumes, lower treatment costs, and reduce third-party disposal expenses for industries with high-TDS wastewater.

Extended Equipment Life

Proper water treatment in cooling systems and boilers — identified through the audit — reduces scale, corrosion, and biological fouling that shorten equipment service life.

Water Security & Resilience

Rainwater harvesting and wastewater reuse identified in the audit reduce dependence on municipal supply and groundwater — improving operational resilience during water shortages.

Frequently Asked Questions — Water Audit Services

What is a water audit and why does my facility need one?

A water audit is a systematic measurement of how water is used, lost, and discharged across your facility. Most Indian industrial facilities lose 20–40% of their water to leaks, inefficient cooling systems, poor reuse practices, and unmetered end uses — without realising it. An audit quantifies exactly where water is going, identifies the highest-value conservation opportunities, and gives you a data-backed action plan to reduce costs and meet regulatory requirements.

How much water saving can we expect from a water audit?

Typical facilities achieve 20–35% reduction in water consumption after implementing audit recommendations. Manufacturing plants with cooling towers, process water, and older distribution networks tend to see the highest savings — often reducing consumption by millions of litres per year. Quick wins such as fixing leaks and optimising cooling tower cycles often pay back within 3–6 months.

Is a water audit mandatory for industries in India?

Water audits are mandatory for certain categories of large water users under state groundwater board conditions and for industries in water-stressed zones regulated by the CGWB. Industries with ZLD (Zero Liquid Discharge) obligations under PCB norms are also required to demonstrate water balance. Even where not mandatory, a water audit is increasingly required for ESG reporting under BRSR, GRI, and CDP frameworks.

How is a water audit different from an energy audit?

An energy audit focuses on electrical and thermal energy consumption. A water audit specifically tracks water flows — supply, process use, losses, and discharge. The two are increasingly conducted together because water and energy are deeply linked: pumping, treatment, heating, and cooling all consume both. Bigeta can integrate water and energy audits into a single site assessment to give you a complete resource efficiency picture.

How long does a water audit take at our facility?

A preliminary audit takes 1–2 days on-site. A comprehensive audit covering all systems typically takes 3–5 days on-site followed by 3–4 weeks for analysis, water balance modelling, and report preparation. Bigeta provides preliminary findings verbally before leaving the site so critical repairs can begin immediately.
