Cooling towers lose water through evaporation, drift, and blowdown (discharge to maintain water quality). We optimize cycles of concentration, reduce drift with proper equipment, and implement chemical treatment programs that minimize blowdown while preventing scale and corrosion. Savings of 20-40% are typical.

ESG (Environmental, Social, Governance) reporting discloses water consumption, efficiency measures, and water-related risks to investors and stakeholders. Frameworks like CDP Water and GRI require standardized metrics. We help companies track water data accurately and report in formats that meet investor expectations.

LEED, IGBC, and GRIHA have water efficiency credits for fixture efficiency, rainwater harvesting, wastewater treatment, and metering. We assess current performance, identify cost-effective improvements, and document compliance. Water credits are often among the most achievable for certification.

Low-flow toilets, urinals, faucets, and showerheads use advanced designs to maintain performance with less water. Modern low-flow toilets use 4-6 liters versus 13+ liters for old models. Sensor faucets reduce waste from running taps. Fixture upgrades often pay back in 1-3 years through water savings.

Sub-meters track water use by tenant, floor, or system (cooling, irrigation, domestic). This visibility enables accurate billing, identifies high-use areas, and detects leaks quickly. Behavior change from awareness alone typically reduces consumption 5-10% before any physical improvements.

Rainwater harvesting captures roof runoff for non-potable uses like toilet flushing, irrigation, and cooling tower makeup. We design collection, storage, and treatment systems sized to your building and rainfall patterns. Properly designed systems can supply 30-50% of non-potable water demand.

Irrigation optimization includes weather-based controllers that adjust watering to actual conditions, drip systems for shrubs and trees, efficient sprinkler heads, and soil moisture sensors. Native and drought-tolerant plants reduce water needs further. Savings of 30-50% versus timer-based irrigation are common.

Greywater is wastewater from sinks, showers, and laundry (excluding toilets). After treatment, it can be reused for toilet flushing and irrigation. Greywater recycling is increasingly required for large buildings in water-stressed areas. We design systems that meet health regulations and building codes.

We use night-flow analysis of meter data to detect base leaks, acoustic sensors to locate hidden leaks, and thermal imaging for hot water leaks. Common problem areas include toilets (flapper valves), cooling systems, and underground irrigation pipes. Fixing leaks often provides the fastest payback for water investments.

A fixed threshold has to be set high enough not to fire on a busy Monday, which means it misses any leak small enough to hide inside normal daytime consumption. A model trained on each sub-meter's own history knows what that meter does on a Tuesday in April at typical occupancy, so a steady overnight flow of a few hundred litres per hour reads as an anomaly even though it never crosses an absolute limit. The same models fill in the gaps when a meter drops out, which matters more than it sounds for ESG disclosure, where an incomplete year of data is a reporting problem rather than a plumbing one. Forecasting is the other half: cooling tower makeup tracks weather closely enough that a short-term forecast is genuinely useful for planning deliveries and treatment chemistry.
