Recover water and utility costs accurately
Dividing the water bill equally means small households subsidise large ones, and a leaking tank is invisible until the quarter closes. Metering fixes both, and the leak detection is usually where it pays for itself.
Metering utilities per flat and billing actual consumption ends the cross-subsidy of equal division and surfaces leaks through abnormal-usage alerts. Consumption reductions of 15% to 30% after introducing metering are a well-documented general effect, not specific to any one platform.
Why this problem persists
Manual reading does not scale, so equal division becomes the default by attrition.
Flat-rate billing punishes light users
A two-person household and an eight-person household pay the same. The households paying more than they use know it, and they raise it at every AGM — usually without being able to prove it, which makes the argument circular.
It is not a small effect. Water consumption between comparable flats in the same building commonly varies by a factor of three or more depending on occupancy and habits.
Readings taken manually, if at all
Reading four hundred meters by hand is several days of work, so it either does not happen or happens inconsistently. Readings taken over several days are treated as if simultaneous, and transcription errors produce bills that are obviously wrong.
A meter that has stopped is discovered months later, if ever, because a flat consuming nothing looks unremarkable when the bill is a flat share anyway.
Leaks show up only in the bill
A leaking overhead tank or a running toilet can waste more water in a month than behaviour change saves in a year. Under monthly manual reading — or under equal division, where individual consumption is never examined — it is invisible until the aggregate bill jumps.
By then the water is gone and the cost has already been spread across every flat.

Four steps, of which the third is usually where the money is.
What changes in 90 days
Three effects, and they are worth separating because they have different levels of evidence behind them.
Utility recovery reaches full cost
This one is mechanical rather than behavioural. Where utilities are billed as consumption on the maintenance invoice, the society recovers what it spent because the charge is derived from the supply cost and apportioned by actual use, and it is collected as part of a bill members already pay.
The failure it removes is utilities being a separate, skippable charge or being under-recovered because the flat rate was set years ago and never revisited.
Consumption typically falls 15 to 30 per cent
This is a well-documented general effect of moving from unmetered to metered utility billing, observed across many contexts and not specific to any one platform. Paying for what you use changes behaviour quickly, and the effect appears within the first few billing cycles.
Be sceptical of the top of that range for your own property. How much you see depends on how wasteful the unmetered baseline was — a property that was already careful has less to recover.
Leak losses caught in days
This is usually where metering pays for itself, and it is the effect most often left out of the business case. A single leaking overhead tank can waste more in a month than behaviour change saves in a year, and the only way to catch it early is to watch the pattern rather than the monthly total.
For plotted layouts with long buried distribution runs, unaccounted-for water between supply and the sum of flat consumption is frequently substantial and entirely invisible before metering.
Features that power this
The same platform, but these are the parts this kind of operation leans on hardest.
Smart utility metering
Automatic reading, consumption billing, and the overnight-flow alerts that catch leaks while they are still cheap.
Maintenance billing
Consumption posts as a line on the regular invoice with readings shown, so it is one payment and one arithmetic a member can verify.
Reporting dashboards
Consumption per flat over time, and total supply against the sum of flat consumption — which is where unaccounted-for water becomes visible.
