Solutions
One telemetry stack, from the farm valve to the city reservoir
Each solution runs on the same field hardware and the same cloud platform, so a single control room can operate an irrigation scheme, a water supply zone and a pumping station side by side.

Outlet Management System · OMS
Automated chak outlets for pressurised irrigation networks
Large piped irrigation projects serve thousands of farmers from one pumping system. The Nebulotix OMS divides the command area into zones and chaks, places a controlled outlet cabinet at each chak, and delivers water in planned rotational shifts with every cubic metre measured.
Field · outlet
Outlet cabinet
4 to 12 hydraulically or electrically actuated valves, a water meter and pressure transmitters on a common manifold, housed in a lockable enclosure with strainer and air valve.
Field · control
OMS RTU
Solar-powered controller that opens and closes outlets by volume or time, logs flow and pressure, detects pipe bursts and tampering, and keeps running its schedule if the link drops.
Network
Gateway
Aggregates RTUs over long-range LoRa radio and backhauls to the cloud over 4G or fibre. Cellular RTUs can connect directly where coverage allows.
Cloud
Nebulotix Control Centre
GIS map of every outlet, schedule planner, alarms, volumetric reports per farmer and per chak, and integration with pump station SCADA.
People
Farmer & WUA app
Water user associations see their shift, delivered volume and complaints status. Farmers receive SMS before and after each irrigation turn.
Why projects automate the outlet
In a gravity canal, tail-end farmers get water last and least. A pressurised network fixes the hydraulics, but only if every outlet opens on time and closes once its share is delivered. Manual operation across hundreds of chaks cannot hold that discipline. The OMS does, and it produces the delivery records that funders, departments and auditors ask for.
Our engineers design the hydraulic side too: outlet pressure heads, manifold sizing, valve selection and surge protection are checked against the network model so the automation is not fighting the pipework.

Illustrative schedule. Real quotas come from crop water requirement, CCA of each outlet and pump availability.
Volumetric quotas
Each outlet closes when its allotted volume is delivered, so allocation follows design discharge rather than who opens the valve first.
Rotational scheduling (warabandi)
Plan shifts by zone, chak and outlet. The schedule is pushed to RTUs and runs locally even during communication loss.
Pressure and burst protection
Low and high pressure limits trigger valve closure and alarms, protecting laterals and identifying pipe failures by location.
Tamper and theft alerts
Door switches, unauthorised flow detection and valve position feedback flag interference at the cabinet.
Pump-network coordination
Open outlet count and demand feed back to the pump station so pumps stage up and down with the schedule.
Audit-ready reporting
Delivered volume per farmer, per chak and per season, irrigation efficiency, downtime and grievance logs, exportable for departments and lenders.

FAQ
Common questions
What is an Outlet Management System in irrigation?
An OMS is an automated control point at each chak or outlet of a pressurised irrigation network. It combines control valves, a flow meter, pressure sensors and an RTU so water is released to each farm group on schedule and in the planned volume, with every delivery recorded.
Does the OMS keep working if the network connection is lost?
Yes. Schedules are stored on the RTU and run locally. Logged data uploads when the link returns.
Can Nebulotix integrate with an existing pump station SCADA?
Yes, over Modbus, MQTT or REST. The OMS can share open-outlet and demand data with the pump station so pumps follow the irrigation schedule.
Which communication options do you support?
LoRa radio between field RTUs and gateways, and 4G LTE, fibre or VSAT backhaul. The choice follows a radio coverage survey of the command area.
Do you work with EPC contractors on government tenders?
Yes. We supply and commission the automation package, prepare technical documentation for tender compliance, and support O&M through the defect liability period.
