AquaLedger
💧 For apartment societies, RWAs and facility managers

Stop paying tanker prices for someone else’s leak.

AquaLedger tracks every litre from municipal supply, borewells and tankers, catches leaks automatically, bills each flat by actual usage and forecasts shortages before the sump runs dry.

  • Set up in a minute
  • Works with manual readings
  • Pays for itself with one leak

Seconds

from an open tap to a live alert, then an email to the committee

Three sources of water. One bill split equally. Nobody sees the leak.

🚰

Municipal supply is rationed and borewells run low every summer, so societies buy tankers at 5-10× the price.

🧾

The bill is split equally so the flat with a leaking cistern pays the same as a retired couple. That's the argument at every AGM.

🌙

Leaks run for weeks because nobody is watching the meters at 3 a.m. Every litre lost is bought back at tanker prices.

Tanker

Cost per kilolitre by source in the sample society. A leak is paid for at the tanker price.

How it works

From meter reading to fair bill, without spreadsheets.

1

Meter every litre

Type readings in, upload the CSV your meter reader sends, or connect smart meters for live data.

2

Catch leaks overnight

Every night each flat is checked for usage spikes and steady 2-4 a.m. flow. Live meters alert in seconds.

3

Bill by actual use

Each flat pays its share of metered litres plus a small common charge. One click, printable bills.

4

Plan tankers early

Next month's demand, tanker count and budget from your history and the season.

Leak detection

Find the running cistern before it costs a month of tanker water

AquaLedger compares every flat with its own normal and watches for water flowing while everyone sleeps. The committee gets an email with the flat, the pattern and the litres being wasted.

  • Usage spikes over 2.5σ above a flat's normal
  • Steady flow between 2 and 4 a.m. on 3+ nights
  • Live alerts within seconds from smart meters

Fair billing

End the equal-split argument at the AGM

The society's real water cost (municipal supply, borewell power and every tanker) is shared by metered litres. Small households stop paying for the garden-hose flat.

  • Shows what every flat paid under the old equal split

Forecast & insights

Know how many tankers you'll need before summer hits

A seasonal forecast tells you next month's demand and tanker budget. Ask questions in plain English: why did the bill go up, which flats use the most, how much did leak detection save.

  • 3-month moving average × seasonal factor
  • Monthly summary written for the committee
  • Plain-English answers from your own data
Forecast and chat with plain-English answers
Live meters

Watch a burst pipe show up in real time

Smart meters stream readings every few seconds. Abnormal flow raises an alert and emails the committee straight away.

What would it save your society?

Move the sliders. Leak savings alone, before fairer bills and better tanker planning.

About 1 in 10 homes has a significant leak (US EPA WaterSense estimate), so a 300-flat society can expect ~30 a year. Each is assumed to waste ~480 L/day, like the running cistern in our sample society, until AquaLedger flags it the next morning. AquaLedger priced at ₹12 per flat per month.

Simple per-flat pricing

A 300-flat society pays about ₹3,600 a month: less than two summer tankers.

Questions committees ask

Do we need smart meters?+

No. Most societies start with the readings they already take: type them in or upload a CSV. Smart meters add live leak alerts, and you can add them flat by flat.

What can residents see?+

Only their own flat: their usage against the building average, and their bills once the committee issues them. Never another flat's data.

How long does setup take?+

About a minute: create the society, add blocks and flats, and log your water sources. You can load six months of sample data first to see everything working.

Where is our data stored?+

On AWS in the Mumbai region, in a fully serverless setup. Each society's data is isolated by its own access group.

What if a reading is wrong?+

Bills stay drafts until the committee issues them, and re-running the bill run never touches bills you've already issued or marked paid.
