The Monsoon Is Ending. Now What? India’s Post-Monsoon Water Action Checklist for Facility Managers

The rain may still be falling in parts of India, but for facility managers, September is the time to start thinking beyond the monsoon. Because the biggest water-management mistake a building can make is assuming that a wet monsoon automatically means a secure water supply for the months ahead. It doesn't. September is the transition point between rainwater management and dry-season water management. The systems that collected, drained, treated and reused water during the monsoon now need to be inspected, measured and prepared for a very different operating environment. And 2026 deserves particular attention.

The India Meteorological Department's initial 2026 Southwest Monsoon forecast anticipated below-normal rainfall at 92% of the Long Period Average, later revised to 90%, with the development of El Niño conditions expected during the season. By early August, cumulative seasonal rainfall was already around 12% below the long-period average. Now, as September begins, IMD expects rainfall to be below normal nationally, following a weak August. The regional picture is also uneven. IMD's seasonal forecast had specifically indicated below-normal rainfall over much of Punjab and Haryana, while recent reporting has highlighted significant rainfall deficits in Punjab and parts of Rajasthan. Meanwhile, groundwater remains under pressure. According to the Central Ground Water Board, 736 of India's 6,553 groundwater assessment units were classified as over-exploited in the latest assessment cited by CGWB, with another 199 classified as critical. That makes September more than just another month on the maintenance calendar. It is your building's water-planning checkpoint.

Here are 10 things every facility manager, building owner and RWA should check before the dry months arrive.

1. Inspect and Clean Your Rainwater Harvesting System

During the monsoon, your rainwater harvesting system may have handled more leaves, silt, plastic, dust and other debris than it normally sees in an entire year. That material doesn't simply disappear when the rain stops. It can settle inside:

• Roof drains

• Gutters

• Downpipes

• Filter chambers

• Recharge pits

• Collection tanks

• Silt traps

• First-flush systems

A system that looks functional from the outside can still be partially blocked.

September action:

Conduct a complete post-monsoon inspection.

Checklist:

☐ Clean roof drains and gutters ☐ Remove accumulated silt☐ Inspect filter media☐ Clean first-flush arrangements☐ Check recharge pits☐ Inspect collection tanks☐ Look for cracks or structural damage☐ Confirm overflow routes are clear☐ Record the condition with photographs

Don't wait until the next monsoon to discover that your rainwater harvesting system wasn't working properly. Make every drop captured during the next rainfall count.

2. Check Your STP After the Monsoon

The monsoon changes the wastewater equation inside a building. Rainwater can enter sewage lines through damaged pipes, open manholes, cross-connections or poorly sealed infrastructure. This can increase hydraulic loading on the Sewage Treatment Plant (STP), potentially affecting treatment performance. Facility teams should therefore treat September as an STP health check.

Review:☐ Inlet flow☐ pH☐ TSS☐ BOD/COD trends☐ Aeration performance☐ Sludge levels☐ Blower/pump condition☐ Odour complaints☐ Treated-water quality☐ Reuse volumes

Also ask an important question:How much treated water are we actually reusing? A building can have a perfectly functional STP and still waste water if treated water is simply discharged instead of being reused for flushing, gardening, cooling or other suitable non-potable applications. Post-monsoon is the right time to identify that gap.

3. Look at the Last Four Months of Water Bills

Water bills can tell a facility manager a story that a walk-through inspection cannot. Don't just look at the amount paid. Look at the trend. Compare your building's water consumption for:

June → July → August → September

Then ask:

• Did consumption rise during the monsoon?

• Did tanker dependence increase?

• Did municipal supply change?

• Did occupancy change?

• Did water consumption per occupant increase?

• Is there a sudden unexplained spike?

• Are treated-water reuse volumes reducing fresh-water demand?

If your building doesn't have monthly water data, that's a warning sign in itself. Start tracking: Freshwater input + recycled water + rainwater captured + wastewater generated + water reused + tanker water You cannot manage what you don't measure. And a water bill is only one part of the picture.

4. Audit Water Waste in Restrooms

Restrooms are among the easiest places to find hidden water waste. A leaking flush valve may look insignificant. A continuously running tap may look insignificant. A urinal flushing unnecessarily may look insignificant. Multiply that by dozens or hundreds of fixtures, thousands of users and 365 days. Suddenly, the “small” leak becomes a significant annual water loss.

Facility restroom checklist:

☐ Check taps for dripping☐ Inspect flush valves☐ Check flush volumes☐ Inspect sensor taps☐ Check dual-flush mechanisms☐ Look for continuously running fixtures☐ Check urinals☐ Review cleaning practices☐ Measure restroom water consumption where possible

And don't overlook urinals. Traditional flushing urinals can consume substantial amounts of potable water every day. A waterless urinal retrofit can remove that recurring flushing demand altogether. This is where a simple fixture-level audit can uncover a surprisingly large opportunity.

5. Check Plumbing for Monsoon Damage

The monsoon is hard on building infrastructure. Water ingress, ground movement, clogged drainage, corrosion and damaged joints can expose plumbing problems that weren't visible during the dry months. Walk the building. Don't only inspect mechanical rooms.

Look at:

• Underground pipelines

• Pump rooms

• Tank connections

• Toilets

• Service shafts

• Basement areas

• Garden irrigation lines

• External pipelines

• Valve chambers

• Overhead tanks

Look for wet patches, unexplained moisture, corrosion, pressure changes and areas where pumps are operating more frequently than expected. Is the building consuming more water than its occupancy should require?If yes, investigate before assuming the additional water is simply “normal usage.” A hidden leak can continue for months.

6. Service and Capture HVAC Condensate

Your building may be throwing away water every day without realizing it. Air-conditioning systems generate condensate. In large commercial buildings, hospitals, hotels, malls and office campuses, this can represent a meaningful source of recoverable water. Instead of allowing condensate to disappear into a drain, facility teams can assess whether it can be safely collected and reused for suitable non-potable applications, depending on site conditions and water-quality requirements. September HVAC check:

☐ Inspect condensate drains☐ Check for leaks and blockages☐ Measure condensate generation where practical☐ Identify discharge points☐ Evaluate collection opportunities☐ Explore suitable reuse applications. Before buying more water, understand how much usable water your building is already throwing away.

7. Change Your Irrigation Schedule for the Dry Season

The landscape that survived the monsoon doesn't need the same watering schedule in September and beyond. Yet many buildings continue using fixed irrigation schedules throughout the year. That's an easy way to waste water.

Review:

☐ Watering frequency☐ Irrigation timing☐ Sprinkler coverage☐ Drip irrigation performance☐ Soil moisture☐ Plant selection☐ Runoff☐ Leakage from irrigation lines

Where possible, schedule irrigation during cooler periods to reduce evaporation. Also distinguish between watering plants and watering the pavement. Broken sprinklers, incorrect spray patterns and excessive pressure can send large quantities of water into walkways and drains instead of landscapes. A dry-season irrigation plan should be based on actual plant requirements not last year's timer settings.

8. Schedule a Q4 Water Audit

If your building doesn't have a formal water audit planned, September is a good time to schedule one. Think of a water audit as a health check for the building's entire water system. It should answer:

Where does water enter the building?

Where is it being used?

Where is it being lost?

Where is wastewater generated?

How much is being treated?

How much treated water is reused?

Where can consumption be reduced?

A good facility water audit should look beyond individual fixtures and examine the building as a complete water cycle. At minimum, map:

Source → Storage → Distribution → Consumption → Wastewater → Treatment → Reuse → Discharge

This creates a baseline for Q4 improvement. It also gives facility managers something much more valuable than a generic sustainability target:actual numbers.

9. Evaluate Waterless Urinal Retrofits

If your building has high-traffic male restrooms, September is a good time to evaluate whether waterless urinals make operational and financial sense. A waterless urinal eliminates the regular flushing requirement associated with conventional urinals. Ekam Eco Solutions' Zerodor uses a mechanical one-way valve rather than oil sealants, cartridges, sensors or electricity. The objective is to eliminate flushing water while controlling odour at the source. For facility managers, the decision shouldn't be based only on the product price. Look at the complete operating cost:

Current flushing water + plumbing demand + maintenance + recurring consumables + wastewater load versus Waterless fixture installation + maintenance + lifecycle cost The potential benefit is not limited to water savings. Reducing unnecessary potable water use can also reduce the volume of water entering the sewage system. For high-footfall facilities, that makes fixture-level water conservation worth investigating as part of a wider water strategy.

10. Set Your BRSR Water Baseline Before the Financial Year Ends

Water management is no longer only a maintenance issue. For many businesses, it is increasingly part of sustainability reporting, ESG strategy and corporate accountability. That's why facility teams shouldn't wait until year-end to start looking for water data. Start building your FY-end baseline now. Track:

☐ Total freshwater withdrawal☐ Municipal water consumption☐ Groundwater use☐ Tanker water☐ Recycled water☐ Rainwater captured☐ Wastewater generated☐ Treated wastewater☐ Water reused☐ Water intensity

If you are responsible for multiple buildings, standardise the data collection format across sites.

This makes year-end reporting easier and, more importantly, makes it possible to compare performance between facilities. Good sustainability reporting starts with good facility-level measurement.

The September Water Action Plan

If you are a facility manager and have limited time, don't try to fix everything at once.

Use this simple sequence.

Week 1: Inspect

Check rainwater harvesting systems, tanks, STP, plumbing, restrooms and irrigation.

Week 2: Measure

Collect four months of water bills and establish current freshwater, recycled-water and tanker consumption.

Week 3: Identify

Find the biggest sources of water loss and the biggest opportunities for reuse.

Week 4: Act

Prioritise projects based on:Water saved + operating cost reduced + payback period + ease of implementation. This prevents water conservation from becoming another long sustainability document sitting in a folder. It becomes an operating plan.

The Question Every Facility Manager Should Ask This September

The wrong question is:“Did our building get enough rain this year?” The better question is:“How prepared is our building for the months when the rain stops?” Because a building's water resilience isn't determined by what falls from the sky. It is determined by what the building captures, measures, saves, treats, reuses and prevents from being wasted. India's groundwater situation makes this increasingly important. CGWB's latest national groundwater information continues to classify hundreds of assessment units as over-exploited or critical, while the organisation explicitly emphasises the importance of measuring groundwater extraction against available resources. And this year's weather adds another layer of uncertainty. IMD's 2026 forecasts pointed toward below-normal monsoon rainfall and the development of El Niño conditions, while September is now expected to receive below-normal rainfall nationally. That doesn't mean every building will face a water shortage. It means every building should know where its water is coming from and where it is going.

Your Post-Monsoon Water Checklist

Before September ends, make sure your facility team can tick these ten boxes:

☐ Rainwater harvesting system inspected and cleaned

☐ STP performance reviewed after the monsoon

☐ Last four months' water bills analysed

☐ Restroom water consumption audited

☐ Plumbing checked for leaks and monsoon damage

☐ HVAC condensate recovery evaluated

☐ Dry-season irrigation schedule updated

☐ Q4 water audit planned

☐ Waterless urinal retrofit opportunity evaluated

☐ FY-end BRSR water baseline started

If several boxes are still unchecked, your building isn't necessarily failing. But it may be missing opportunities to save water, reduce operating costs and become more resilient before the dry months arrive.

Don't Wait for the Water Shortage to Start Measuring Water

The best time to discover a water leak is before the bill arrives. The best time to discover an inefficient restroom is before water consumption spikes. The best time to discover an underperforming STP is before complaints begin. And the best time to prepare for the dry season is before the dry season arrives.

Frequently Asked Questions

Q1. Why is post-monsoon water management important for buildings in India?

The end of the monsoon marks a transition toward drier months when dependence on municipal water, groundwater and tankers can increase. Post-monsoon is the right time to inspect rainwater harvesting systems, identify leaks, review water consumption and prepare STPs, irrigation systems and other infrastructure for the dry season.

Q2. What should a facility manager check after the monsoon?

A post-monsoon inspection should cover rainwater harvesting systems, storage tanks, STPs, plumbing networks, restrooms, irrigation systems, HVAC condensate lines and water meters. Facility managers should also review recent water bills and identify unusual changes in consumption.

Q3. When should a building conduct a water audit?

A water audit can be conducted at any time, but September is a particularly useful period for a post-monsoon assessment. It allows facility teams to identify water losses and inefficiencies before the drier months and establish a baseline for Q4 planning and sustainability reporting.

Q4. What does a facility water audit include?

A facility water audit typically maps the building's complete water cycle—from incoming freshwater and storage to consumption, wastewater generation, treatment, reuse and discharge. It can also identify leakage, inefficient fixtures, excessive irrigation and opportunities to increase treated-water reuse.

Q5. How can buildings reduce water consumption in restrooms?

Buildings can reduce restroom water consumption by fixing leaks, installing efficient taps and flush systems, optimising sensor settings and evaluating waterless urinals. High-footfall buildings can particularly benefit from examining how much potable water is being used for routine urinal flushing.

Q6. Can waterless urinals help commercial buildings save water?

Yes. Waterless urinals eliminate the regular flushing water required by conventional urinals. For high-occupancy facilities such as offices, malls, airports, hotels and institutional buildings, evaluating waterless urinals can be a practical part of a broader water-efficiency strategy.

Q7. What should I do with my rainwater harvesting system after the monsoon?

Inspect and clean the system thoroughly. Remove leaves and accumulated silt from gutters, drains and filters, inspect recharge pits and collection tanks, and check that overflow pathways remain clear. Documenting the condition now also makes the system easier to maintain before the next monsoon.

Q8. How can an STP help reduce a building's freshwater demand?

An STP treats wastewater so that suitable treated water can potentially be reused for applications such as toilet flushing, landscaping and other non-potable requirements, subject to applicable quality requirements. Increasing appropriate reuse can reduce dependence on fresh water.

Q9. Why should facility managers review water bills from the last four months?

Looking at several months together helps reveal consumption trends rather than isolated numbers. Sudden increases can indicate leaks, changes in occupancy, increased tanker dependence, inefficient fixtures or other operational issues that may otherwise go unnoticed.

Q10. What is the connection between water management and BRSR?

Water consumption, withdrawal, discharge, recycling and reuse can form part of an organisation's sustainability and ESG reporting. Establishing reliable facility-level water data early makes it easier for organisations to build consistent year-end baselines and report their performance accurately.

Q11. Can HVAC condensate be reused?

HVAC systems generate condensate that may be recoverable in some buildings. Facility teams can measure the quantity generated and evaluate whether collection and reuse for appropriate non-potable applications is technically and operationally feasible.

Q12. What is the first step if I don't know how much water my building is wasting?

Start by measuring. Review water bills, meter readings, tanker records, STP data and major consumption points. A professional water audit can then help map the building's water cycle and identify the highest-priority opportunities for savings.

Q13. How can Ekam Eco Solutions help with building water management?

Ekam Eco Solutions works on sustainable sanitation and water-management solutions for facilities, including water-saving interventions, wastewater treatment and waterless sanitation. A water audit consultation can help identify practical opportunities to reduce water consumption, improve reuse and prepare the facility for the dry season.
