Snap. Send. Save. Water Monitoring
Water is one of the most significant operational expenses facing schools today. Yet, despite rising municipal tariffs, many School Governing Bodies (SGBs) and facility managers are forced to rely solely on monthly municipal invoices to understand their consumption. By the time an inflated utility bill arrives, thousands of litres—and thousands of Rands—may have already been lost.

Water is one of the most significant operational expenses facing schools today. Yet, despite rising municipal tariffs, many School Governing Bodies (SGBs) and facility managers are forced to rely solely on monthly municipal invoices to understand their consumption. By the time an inflated utility bill arrives, thousands of litres—and thousands of Rands—may have already been lost.
The conventional solution would be to install real-time electronic water meters. However, hardware logging involves digging, primarily trenching, plumbing, power connections, and high capital outlay, which is often a major deterrent for most schools.
Quem não tem cão, caça com Gato
There's an an old Portuguese proverb: Quem não tem cão, caça com Gato, meaning: If you don’t have a dog, hunt with a cat...
Working in collaboration with partner schools across Johannesburg, we developed a pragmatic, low-cost alternative: recording manual meter readings at the start and end of each school day, which were transferred to a spreadsheet and graph and report. This later developed into a photo being sent by What’sApp to Suntricity Admin, which were transferred to a spreadsheet and graph and report. This simple though time consuming process isolates daytime operational consumption from overnight loss, giving clues to where we must focus.
Technology Upgrade
Having introduced Optical Character Reading (OCR) to the redesigned Suntricity Platform, and with What’sApp offering enhanced services to their platform, the simple process became simpler by the introduction of AI agents. The water meter image is still sent by What’sApp but to a Business Account, where it is picked up by OCR where the relevant data is extracted, then Saved to the Suntricity’s platform database.
Sending the image via What’sApp automatically brings all the metadata of the school, which is transferred, organised and presented for verification by Suntricity Admin, who then approves for publication to the school’s dashboard.
The 3-Step Routine:
The entire monitoring system therefore revolves around a simple, twice-daily routine:
- SNAP: A staff of the ground member goes to the water meter, opens What’sApp and takes a photo; twice a day-at the start (AM), and at the end (PM) of the day.
- SEND: The photo is then sent directly to Suntricity Monitoring via WhatsApp.
- SAVE: The image is instantly processed and logged on the central database:
- PM Reading minus AM Reading = DURING SCHOOL HOURS consumption.
- AM Reading minus previous PM Reading = OUTSIDE SCHOOL HOURS consumption.
Verify OCR Results (Human-in-the-Loop): Pure OCR automation often misread data on the water meter, which the system automatically flags. Administrators verify and correct extracted figures before entering to permanent record, preventing data from corrupting your analytics.
Estate managers, bursars, and SGB members have access to their dashboard to continuously track water performance and investigate anomalies.
Why Suntricity Works for School Environments
Without this twice-daily snapshot, waste quietly persist for weeks, accumulating unnecessary municipal charges. By isolating outside school hours usage, schools identify infrastructure failures before they become financial burden.
- Low Friction: Operating inside What'sApp means zero learning curve for facility staff and no technical friction.
- High Trust: Human-in-the-loop verification eliminates false readings and ensures reports are 100% audit-ready for SGB presentations.
- Priority Action: Outside school hours consumption is immediately considered waste, which makes plumbing maintenance priorities clear.
- Effective & Affordable: Requires zero hardware investment. SGBs gain continuous visibility without taking on capital expense or risk.
Start Saving Water Today
Establishing twice-daily water monitoring should be considered a fundamental baseline for sound school utility governance. Beyond daily leak detection, timestamped photo evidence provides your finance committee with audit-ready proof in the event of disputing inaccurate municipal billing.
