A monthly water budget report should tell a housing society committee how much water was verifiably received, what is known about storage and use, which services are at risk, what the society spent, and which numbers remain estimates. The report should use the same definitions and boundaries as the society's water budgeting method. It should support decisions without presenting tank-level movement as a direct measurement of all incoming water or consumption.
Copy-and-fill committee report
Society: [name] | Reporting period: [start and end] | Prepared by: [facility manager] | Reviewed by: [committee representative] | Record cut-off: [date/time] | Data quality: [complete / partial / provisional].
Executive summary
Supply received: [verified volume and units, or “not independently measured”]. Current storage: [measured level / estimated volume, tank and timestamp]. Reliability: [verified interruptions and affected services]. Cost: [actual invoiced amount, accrual or estimate, clearly labeled]. Main risk: [evidence-supported statement]. Decision requested: [specific action, owner, cost and deadline]. Material unknowns: [missing meters, stale readings, supplier confirmation, etc.].
1. Source ledger
Use one line per independently evidenced delivery or source-period. Fields: source (municipal, borewell, tanker or other); water category; source record ID; receipt date/time; volume; unit; measurement method; confidence; supporting document; verified by. Separate a booked tanker from an arrived tanker. Where an incoming meter is absent, enter “unmeasured,” not a number inferred solely from a tank-level increase. If a transfer moves water from an underground tank to an overhead tank, record it as an internal transfer, not a second external supply receipt. Do not mix drinking, domestic and treated/recycled water as if interchangeable.
2. Storage snapshot
For each tank record: tank ID; water category; timestamp; sensor reading and freshness; usable capacity if validated; estimated stored volume where tank geometry is configured; operating reserve; current restriction or maintenance; source of verification. A tank reading is a point-in-time snapshot. Summing volumes across connected tanks requires avoiding duplicate reporting of transferred water as new supply. Flag readings from different timestamps and inaccessible tanks.
3. Demand and reconciliation
If independently metered demand exists, record the meter, coverage and period. Otherwise describe the net storage change and known supply/transfer records without claiming to know total consumption. The physical accounting relationship for a defined system boundary is: closing storage minus opening storage = external inflow minus external outflow, adjusted for known internal boundary transfers and measurement error. A level fall while supply continues does not reveal consumption alone. Distinguish a confirmed no-inflow observation from an assumed pump-off period. A short controlled observation is not automatically representative of the month.
Illustrative reconciliation only, not Park Astra or another customer result: a hypothetical tank starts with 100 kilolitres, receives 40 kilolitres of independently metered inflow and ends with 90 kilolitres. With no other transfers, measured losses or errors, the implied outflow is 50 kilolitres (100 + 40 - 90). If the 40-kilolitre inflow is not independently known, the same 10-kilolitre net storage decline does not establish 50 kilolitres of outflow. Record uncertainty instead of filling a balancing difference with a guessed leak volume.
4. Service and operational reliability
Record the number of verified interruption incidents, affected towers and water categories, opening and restoration times, physical checks, notices issued, and unresolved causes. Distinguish a pump-trip finding, a supply restriction and unusually high resident demand. A graph can direct investigation, but physical checks establish equipment or pipe defects. Do not assign a cause to residents based on tenancy or an unadjusted depletion trend.
5. Financial report
Separate water purchases by source; transport; energy where attributable; maintenance; sensor/monitoring subscription; emergency costs; and one-off capital works. Show actual paid, invoiced but unpaid, and estimated costs separately. Cost per kilolitre = comparable total cost divided by verified volume for the same boundary and period; if volume is unavailable, mark this KPI “not available.” Avoid counting the same invoice in both purchase and emergency totals. Report changes from the prior period only when the periods, service mix and measurement methods are comparable.
6. Risk register and actions
For each issue state: evidence; affected service; likelihood or severity as assessed by the committee; immediate mitigation; owner; due date; approval needed; next review. Examples of risk categories are unreliable incoming supply, inadequate refill, stale telemetry, an unverified tanker receipt and missing flow measurement. Do not state that every abnormal trend indicates a leak.
7. Resident-facing summary
A short committee-approved version may state: “During [period], we recorded [verified service facts]. Current tank readings show [tank-specific snapshot and timestamp]. [Supply volumes or consumption] remain [measured / estimated / unavailable]. The facilities team is [verified action]. Our next update is [time/channel].” Exclude private resident information, speculative causes and unverified restoration promises.
Committee dashboard: six useful indicators
Verified external water received: measured receipts only, with source and units.
Storage status: level or estimated volume by tank, with timestamp and freshness.
Supply reliability: verified interruption count and duration by service.
Source cost: actual comparable cost, with exclusions and accounting period.
Data completeness: proportion of required records actually available, where a documented denominator exists.
Open decisions: owner, due date, approval and evidence needed.
Do not publish a numerical KPI merely because a dashboard can display a calculated value. A blank or “not independently measured” entry is more informative than false precision.
Reporting cadence and sign-off
Facilities should close the operational log after the reporting period, reconcile supplier and invoice evidence, flag gaps and send a provisional report for committee review. The committee approves any public summary and records its decisions. A correction should preserve the earlier version and identify the revised figure, reason and approver. There is no universal monthly statutory reporting format asserted here; adapt this example to applicable local rules and society policy.
TownEve capability boundary
Current TownEve production provides contactless ultrasonic overhead and underground tank monitoring, live and historical levels, configured email alerts, role-based visibility and tank-specific stored-volume calculations derived from measured depth and configured geometry. Tank-specific 0% and 100% reference levels define the usable range, and telemetry freshness can be monitored. Direct pump-state monitoring, pump control, automatic leak detection and automated valve operation are not released capabilities. TownEve has tested its sensor-assisted manual branch-isolation investigation and continues to refine it; it is not an automatic consumption report.
FAQ
Can the committee calculate daily per-person consumption from tank levels alone? Not reliably when inflow and outflow overlap and source records are missing. Use independently measured flow or a carefully qualified estimation method with known operating conditions.
Should we total all tank-level increases as supply? No. Internal transfers can cause double-counting and level changes are net of simultaneous outflow.
How do we report an uncertain number? State the observation, source, assumption, coverage and confidence; use “not measured” where necessary.
Is a lower storage level always a shortage? No. Interpret it against refill schedules, usable reserve, service category and verified demand.
Can a monthly report diagnose a pipe restriction? It may highlight unequal refill trends, but a physical investigation is needed to identify the actual restriction.
