How Housing Societies Can Reduce Water Bills and Depend Less on Tankers Every Summer

This year summers are harsher than earlier years or feel so? The struggle begins in residential societies across India for water, as Water pressure drops. Borewells water level lowers. Tankers become expensive. Residents complain about the shortage, which results in RWAs rushing to manage additional tankers and reduce wastage.

By peak summer, many mid-sized housing societies spend lakhs every month just to maintain daily water supply. The real issue is not only the water scarcity but also the poor water management.

Large amounts of water are wasted daily by households via:

. Leakages

. Inefficient plumbing line in the society

. Overwatering of plants / Spillage

. Poor STP operations

. Manual irrigation

. Lack of on ground monitoring

And most societies discover the problem only after they realise that costs have spiralled out of control.

Areas Where Housing Societies/ Homes Lose Water

1. Hidden Plumbing Leaks

One of the biggest sources of water loss is the invisible leakage inside the plumbing/distribution system within the organisation.

Leaks from:

. Underground pipes develop rust/start dripping due to wear & tear

. Tank overflows on the roof, with no automation

. Faulty float valve

. Pressure imbalance

. Old joints

…can lead to waste thousands of litres every day without being noticed.

In older societies, internal water loss can become surprisingly high before anyone investigates the root cause.

2. Non-Functional STPs

Many large residential complexes already have Sewage Treatment Plants (STPs), and a significant number operate inefficiently or remain partially unused. Many times the STP water is used in flushing tanks and also seen

. STP water gets discharged on the road or left in adjoining land

. As a result, Fresh water is used in absence of treated water 

. Tanker dependency increases multifold

A properly functioning STP allows treated water reuse for:

. Gardening

. Flushing

. Parking cleaning

. Common area washing

This alone can reduce freshwater consumption significantly.

3. Inefficient Garden Watering

In almost all societies, we see efforts put in by residents and RWA, Horticulture teams giving their best to maintain greenery & landscaping, while the watering still depends on manual hose.

This leads to:

. Uneven irrigation around, in some cases overwatering. Evaporation loss and water wastage during daytime heat

During Indian summers, a large percentage of water evaporates before plants can even absorb it.

Smart irrigation systems/Drip irrigation systems improve efficiency considerably.

4. High Resident Consumption

Daily water usage inside apartments also plays a major role in the water consumption pattern.

Common habits increase unnecessary consumption such as, Washing cars with hoses (Fresh Water), Running taps continuously while washing utensils, shower, shaving, and more….

. Running washing machines on half-load 

. Excessive flushing by kids

. Poor fixture maintenance

Awareness and metering often reduce waste more effectively than strict enforcement.

How Professional FM Companies Help Reduce Water Waste

1. Conducting Water Audits

The first step is understanding where water is actually being used — and lost.

A professional water audit studies:

. Inlet supply

. Tank storage

. Distribution systems

. Consumption patterns

. Leakage points

The gap between supplied water and actual usage often reveals hidden wastage.

Without data, most societies only guess where the problem exists.

2. Monitoring Water Systems Digitally

Modern FM operations increasingly use Smart flow meters, Water Consumption dashboards, Sensor-based monitoring and leak/dampening alert and more….

3. Optimising STP Operations

A properly managed STP is one of the biggest long-term savings opportunities for the residential societies.

When maintained correctly, treated water can be used for:

. Flushing/Gardening/Cleaning/Car washing

This reduces dependency on fresh water sources and expensive tanker supply.

Professional FM teams also manage:

. Chemical dosing/Sludge handling/Compliance reporting/Daily parameter checks

Without regular technical oversight, STP performance usually drops over time.

4. Introducing Smart Irrigation

There are many Modern irrigation systems which can be used by RWA/FM agencies:

. Timers/Drip lines/Moisture sensors

The Watering is scheduled during cooler hours when evaporation is lower. This improves landscape health while reducing unnecessary water usage.

5. Rainwater Harvesting Maintenance

Many buildings install rainwater harvesting systems but fail to maintain them properly. Filters clog. Storage systems become unusable. Recharge effectiveness reduces.

An FM team helps ensure: Pre-monsoon cleaning is undertaken across all lines and pits. Filter maintenance and Storage inspection

When maintained well, rainwater harvesting supports groundwater recharge and reduces long-term dependency on external supply.

6. Individual Water Metering

When residents can see their actual water consumption, behaviour changes naturally.

Flat-level water metering creates: Accountability/Usage awareness/Fair billing, faster leak identification

Why Preventive Plumbing Maintenance Matters

Most plumbing failures do not happen suddenly. There are warning signs appear gradually: Pressure fluctuations between hours/floors lead to Regular tank overflow and damp walls. Weakening of pipes happen due to frequent motor cycling and unusual consumption spikes.

Quarterly inspections help identify these issues early before water loss becomes expensive.
