Water and Utility Billing for Housing Societies: A Fair, Reconciled Sheet

Water is one of the most disputed charges in housing societies, especially where tankers supplement the municipal supply. Members who use less object to paying the same as heavy users; members without meters object to estimated charges. A clear, consistent method — approved by the general body and applied every month — removes most of the argument.

Step 1: Collect the month's costs

List every water cost: the water-board bill, each tanker with litres and cost, treatment or sewage-plant running costs if your body charges them through water, and pump electricity if you allocate it here. The costs sheet totals litres and amount.

Step 2: Choose the method

The general body decides — the sheet supports the common choices:

• A fixed part shared equally by every flat (for example, to cover fixed charges and common-area use) — set the percentage.
• A variable part shared by consumption: metered flats by their own reading.
• Unmetered flats either as the average metered flat (“Equal”) or by area using an assumed litres per square foot (“Area”).

Step 3: Enter readings

For each flat, enter the previous and current meter reading. Consumption calculates; unmetered flats get the consumption your method assigns. Each flat's bill is its fixed share plus its variable share of the month's cost.

Step 4: Reconcile

The reconciliation sheet compares total cost with total billed. Any difference should only be rounding. If you see a bigger gap, check for flats missing from the list or readings entered in the wrong unit.

Meter reading discipline

• Read meters on the same date each month, with a photo of each meter if possible.
• Record faulty meters and switch those flats to the unmetered method until repaired.
• Publish the readings with the bill so members can check their own.

Other utilities

The same structure works for common-area electricity, diesel for generator backup and piped gas where the society pays a bulk bill — change the cost heads and the sharing basis. Where the society resells electricity through sub-meters, check your state's electricity rules; some do not allow resale by a society without permission.

Billing it

Add the water bill to the monthly maintenance bill as a separate line in the maintenance ledger, so members see it separately and the GST check applies to the total contribution. SocietyOne bills water and electricity with or without meter readings and apportions common-area charges automatically — see meters in SocietyOne.

Worked example (illustrative)

In April a society pays ₹21,000 for the water-board bill and ₹1,800 for a tanker — ₹22,800. The general body has decided 20% is a fixed charge shared equally and 80% is shared by consumption. Flat A-101's meter shows 8,500 litres; flat A-102 has no meter and, under the “Equal” method, counts as the average metered flat. Each flat's bill is its equal share of ₹4,560 plus its share of ₹18,240 in proportion to consumption. The reconciliation shows ₹22,800 billed against ₹22,800 cost.

Common mistakes

• Meters read on different dates each month.
• Faulty meters left in use.
• Water billed inside maintenance so members cannot see it.
• Tanker purchases without receipts.
• Changing the method mid-year without a general body decision.

Presenting it to members

Publish the month's cost sheet, the readings and the method with the bill. When members can see that the tanker cost rose in May because the municipal supply fell, the higher bill is easier to accept — and anyone who doubts their reading can check it against the photo.
