Water supply SCADA and DMA monitoring for 24×7 supply
Flow, pressure and reservoir level across every district metered area, automatic OHT and ESR filling, and night-flow analytics that show where non-revenue water is being lost.
Measure the network before trying to manage it
Most Indian distribution networks are run on intermittent supply hours, with reservoirs filled and valves operated by hand. Without zone-level metering, utilities cannot separate real losses from billing losses, cannot see which zones are under-pressured, and cannot plan a move to continuous supply.
Nebulotix sets up the measurement layer: bulk meters and pressure loggers at DMA inlets and critical points, level and inlet valve control at overhead and ground reservoirs, and a Control Centre that turns this into supply-hour, pressure and water-balance reports.
The DMA boundaries, logger locations and valve settings are planned with the network hydraulic model, so the telemetry answers the questions the utility actually needs to act on.
What is supplied
DMA inlet stations
Electromagnetic or ultrasonic bulk meter with pressure transmitter and battery or mains RTU at each zone inlet.
Reservoir automation
OHT, ESR and GSR level sensing with motorised or hydraulic inlet valve control to prevent overflow and balance filling.
Critical-point pressure loggers
Battery loggers at tail ends and high points to verify service pressure.
PRV monitoring
Upstream and downstream pressure at pressure-reducing valves to confirm settings and detect faults.
Control Centre
GIS view of zones, supply hours, water balance, alarms and NRW reports by DMA.
| Item | Typical configuration | Notes |
|---|---|---|
| Bulk metering | Electromagnetic / ultrasonic | DN 80 – DN 600 typical |
| Pressure | 0 – 10 / 0 – 16 bar | 4–20 mA or digital |
| Reservoir level | Radar / ultrasonic / hydrostatic | With high and low alarms |
| Inlet valves | Motorised butterfly or hydraulic altitude valve | Level-controlled |
| RTU power | Mains, solar or 5–10 year battery | Depending on site |
| Communication | 4G / NB-IoT / LoRa | Selected by site coverage |
Typical values. Final selection follows site survey, hydraulic review and the project specification.
What the utility gets
Zone water balance
Inflow, billed consumption and losses by DMA to prioritise leak detection.
Minimum night flow
Night-flow trends that flag new bursts and background leakage.
Reservoir overflow control
Inlet valves close on high level; overflow events are logged.
Pressure management
Critical-point and PRV data to set and verify pressure zones.
Supply-hour reporting
Actual supply duration and pressure per zone against the target.
Open data
Exports and APIs for utility billing, GIS and state dashboards.
Survey, supply, operate
Survey and design
Hydraulic review, instrument and valve placement, radio coverage study.
Supply and install
Field equipment installed, commissioned and tagged on GIS.
Operate and maintain
Remote monitoring, preventive maintenance and operator training through O&M.
What is a district metered area (DMA)?
A DMA is a hydraulically isolated zone of the distribution network, typically 1,000 to 3,000 connections, fed through one or two metered inlets. Comparing inflow with consumption and night flow shows where water is being lost.
Can telemetry be added to an existing network without shutdowns?
Mostly. Insertion or clamp-on meters and hot-tapped pressure points avoid shutdowns at many sites. Full-bore meters need a planned short shutdown.
Does this help a move to 24×7 supply?
Yes. Zone metering, pressure data and reservoir control are prerequisites for planning and verifying continuous pressurised supply.
