Rajkot's water

Seasonal rivers, Narmada-filled dams and deep hard-rock borewells

The Aji and Nyari run dry outside the monsoon, so Rajkot leans on reservoirs topped up with Narmada water through SAUNI and on borewells drilled deep into hard rock. Storage and pump protection decide how your building copes.

Rajkot sits on the Aji and Nyari rivers, both dry except in the monsoon, so the city's water depends on what its reservoirs catch and what the Narmada adds. Since June 2017, SAUNI pipelines have filled the Aji dam with Narmada water. RMC treats it at the Aji filter plants and the Raiyadhar plant. Borewells go deep into hard rock, up to around 500 m within the city, and CGWB flags fluoride, salinity and hardness. Devyami's level controllers, protected pumps and RO plants suit everything from Kalavad Road bungalows to foundries in Shapar and Metoda.

How water reaches you in Rajkot

  1. Step 1

    Monsoon reservoirs

    Dams on the Aji, including Aji I and Aji II at Rajkot, store monsoon run-off, because the Aji and Nyari rivers run dry for most of the year.

  2. Step 2

    Narmada top-up

    Under the SAUNI scheme, pipelines carry Narmada water across Saurashtra to refill dams such as Aji when local rain falls short.

  3. Step 3

    Filter plants

    RMC's Aji filter plants in the East Zone and the Raiyadhar plant in the West Zone treat and chlorinate the water before it enters ward networks.

  4. Step 4

    Your tank

    Your sump or overhead tank holds each supply, and a borewell, where you have one, covers the gaps.

  5. Where we take over

    Your tank, automated

    Sensors read every tank, an APCON controller runs and protects the pump, and the app shows it all on your phone.

Rajkot's water, honestly

What Rajkot throws at your water system, and the fix for each

Rivers that run dry

The Aji and Nyari carry water only in the monsoon, and Rajkot's rainfall swings widely, from under 160 mm in some recorded years to over 1,300 mm in others. What the reservoirs catch, plus Narmada water brought in through SAUNI, has to last the year.

How we fix it

Every litre that reaches your sump should end up in a tank, not on the terrace. Our multi-tank level controller fills each overhead tank in turn from one pump set, stops at full and protects the pump when the sump runs low.

Fluoride and hardness in borewells

CGWB found fluoride above the 1.5 mg/l limit at 21 monitoring stations in Rajkot district, with total hardness from about 110 to 1,580 mg/l and TDS from about 550 to 3,950 mg/l. It also lists salinity and contamination from poorly built wells among the district's groundwater problems.

How we fix it

RO is the dependable answer for fluoride in drinking water, with a softener for the rest of the house. For societies and factories, our RO controller watches pressure and output quality so the plant does not quietly drift.

Deep wells in hard rock

Borewells in Rajkot city are drilled with down-the-hole hammers, in places to around 500 m. CGWB lists fast-declining water levels as the district's first groundwater problem.

How we fix it

Deep submersibles need protection more than most. Our motor driver cuts out on dry run, overload, voltage faults and single phasing, so a falling water table costs you a pause, not a rewound motor.

Water for foundries and workshops

Rajkot has around 500 foundries, clustered in Aji Vasahat, Gondal Road, Bhavnagar Road, Shapar, Veraval and Metoda, alongside units making bearings, diesel engines and machine tools. RMC itself announced a pilot SCADA-based water monitoring system in its February 2026 budget to curb wastage.

How we fix it

One app can watch every tank, cooling-water sump and pump across a plant, with alerts when a level drops or a motor trips, so a dry tank never stops a shift.

Fierce summers, sharp winter lows

Rajkot airport has recorded 47.9°C in May and has dipped to −0.6°C in winter. Typical winter days run from about 10°C to 22°C.

How we fix it

Rooftop solar water heaters make the most of the long sunny season, and a heat pump covers cold mornings. Our controller makes sure the cheaper heat source runs first.

Through the year

Rajkot's water, season by season

Summer

Mid-March to mid-June is hot and dry, typically between 24°C and 42°C, with both rivers dry and every tank working hard.

Dry-run protection and usage alerts →

Monsoon

Rain arrives from mid-June and fills the Aji and Nyari for only a few months, and the season's total varies sharply from year to year.

Dewatering pumps and UV treatment →

Winter

Winters are clear and cool, around 10–22°C on typical days with occasional cold snaps, and Arabian Sea cyclones can follow the rains.

Watch it run

Watch a building in Rajkot run its own water

This is the same diagram our customers see in the app. The sump and the overhead tank are both sensed, and one APCON controller decides when the pump runs.

  • The pump starts when the overhead tank is low, but only if the sump has water to give
  • It stops at your full level, so the tank never overflows
  • Dry run, overload and voltage faults trip it before the motor is damaged
  • Your phone shows each level, each pump run and each alert as it happens

Questions from Rajkot

What people here ask us

Our Kalavad Road society has three wings and one pump. Can it fill all the tanks?

Yes. Our multi-tank level controller fills each wing's overhead tank in turn from the same pump set, using wired or LoRa wireless sensors on each tank. It stops when all are full and protects the pump if the sump runs dry.

Our borewell water in Rajkot tastes salty and leaves white marks. What treatment do we need?

That usually points to high TDS and hardness, and Rajkot groundwater can also carry fluoride above safe limits. Test first, then use RO for drinking and cooking and a softener for bathrooms and the geyser. We size, install and service both.

Can a factory in Shapar or Metoda monitor its water tanks remotely?

Yes. Our IoT app shows levels in every tank and sump, pump status and alerts on your phone, from a single shed to a multi-building plant. Pair it with motor drivers so a dry tank or a voltage fault stops the pump instead of damaging it.

Do you install and service Devyami systems in Rajkot?

Yes. Tell us about your building, society or factory and our engineers design the system around Rajkot's water. A Devyami dealer or installer then installs, commissions and services it locally, and every connected controller can be checked remotely through our platform. The first site consultation is free.

Will the automation keep working without internet or after a power cut?

Yes. Level switching, pressure control, schedules and every motor protection run inside the controller on your wall, not in the cloud. The internet only carries the live view and alerts to your phone. The controller keeps its own real-time clock and remembers its delays through a power cut.

Can you automate my existing pumps and tanks without new wiring?

Usually, yes. The APCON Motor Driver takes the old starter panel’s place on the wall, on the pump and tanks you already have. Wireless level sensors reach terrace and underground tanks where running a cable would mean breaking walls. A single-pump retrofit is usually done in a few hours.
