Bengaluru's water

Cauvery on a timetable, borewells running ever deeper

Bengaluru's Cauvery water is lifted around 350 metres from a reservoir about 90 km away, then shared out by schedule. We build the tank, pump and borewell systems that make that schedule liveable: automatic, protected and visible on your phone.

Bengaluru sits around 350 metres above the KRS reservoir, so every litre of Cauvery water is pumped uphill before BWSSB shares it out, on alternate days in many areas, less in outer layouts. Stage V, opened in October 2024, has reached most of the 110 villages on the city's edge, from Mahadevapura to Bommanahalli, while the 2024 summer showed how fast borewells fail. Our level controllers fill sumps and overhead tanks the moment supply arrives, dry-run protection guards deep submersibles, RO handles nitrate-laden borewell water, and LoRa sensors put every tank in Whitefield or Malleshwaram on one screen.

How water reaches you in Bengaluru

  1. Step 1

    TK Halli intake

    Water is drawn from the Cauvery and treated at Thorekadanahalli (TK Halli), far below the city's elevation.

  2. Step 2

    Uphill pumping

    Pumping stations at Harohalli and Tataguni lift it towards the city, where it arrives at Vajarahalli near Banashankari 6th Stage.

  3. Step 3

    BWSSB distribution

    Ground-level reservoirs feed BWSSB's network, which supplies many areas on alternate days rather than round the clock.

  4. Step 4

    Your sump

    The sump catches whatever arrives, Cauvery, borewell or tanker, and a pump lifts it to the overhead tank.

  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.

Bengaluru's water, honestly

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

Supply that arrives on a schedule

BWSSB has long supplied many areas on alternate days, and outer layouts have at times received water once a week. Cauvery supply covers only part of the city's need: around 1,460 MLD drawn against demand estimated at about 2,600 MLD. Apartment sumps have to catch every window.

How we fix it

A multi-tank level controller starts the pump set only when the sump has water and fills each block's overhead tank in turn, stopping cleanly at full, so nobody has to wait up for the supply hour.

Borewells that fail without warning

During the 2024 crisis, 6,997 of the city's estimated 16,781 borewells had dried up. Nearly half of Bengaluru has depended on borewells and tankers, and a submersible running on a falling water column can burn out quickly.

How we fix it

Our motor driver trips the submersible on dry run, overload, under or over voltage and single phasing, before the winding is damaged and the pump has to be pulled out of the bore.

Tanker water bought blind

In early 2024 a 6,000-litre tanker that used to cost Rs 450 to 600 climbed to Rs 2,000 to 3,000, until the government capped rates at Rs 600 within 5 km. At those prices, guessing your sump level gets expensive.

How we fix it

Wired or LoRa wireless sensors report sump and tank levels to the Devyami app, so you can see what each tanker actually added and get an alert well before you run low.

Nitrate in borewell water

A Department of Mines and Geology survey of 2,209 groundwater samples across the city found nitrate above the permissible limit in 29% of them. Around 31% of samples were unfit for drinking on at least one count.

How we fix it

We size RO plants for drinking water with filtration ahead of them, and our RO controller watches pressure and treated-water quality so membranes are not run to failure.

Drinking water off-limits for gardens

In March 2024 BWSSB banned the use of drinking water for washing vehicles, gardening, fountains and construction, with a Rs 5,000 fine for a first offence. Apartment lawns and villa gardens still need water, just not from the drinking supply.

How we fix it

Our irrigation controller runs gardens and fountains on fixed schedules from a treated or recycled water line, keeping the drinking-water sump out of the garden altogether.

Through the year

Bengaluru's water, season by season

Summer

March to May is when borewells sag and tanker prices climb, so storage, automatic filling and dry-run protection matter most.

Dry-run protection and usage alerts →

Monsoon

September to November is usually the wettest stretch of the year, and BWSSB requires rainwater harvesting on 60x40 ft plots and on newer 30x40 ft sites.

Dewatering pumps and UV treatment →

Winter

December to February brings cool mornings rather than real cold, conditions in which a heat pump heats water efficiently all season.

Watch it run

Watch a building in Bengaluru 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 Bengaluru

What people here ask us

How do we automate the pumps in a Bengaluru apartment that uses Cauvery, borewell and tanker water?

Start with the sump. A multi-tank level controller reads the sump and every overhead tank, runs the pump set only when there is water to lift, and fills the tanks in order. Add the Devyami app and the committee sees levels and pump hours without climbing to the terrace.

Our borewell dries up every summer. How do we stop the motor burning out?

Fit a motor driver with dry-run protection on the submersible. It trips the moment the pump loses water and also guards against overload, voltage swings and single phasing. That is far cheaper than pulling a burnt pump out of a deep bore.

Is a heat pump worth it for an apartment in Bengaluru?

For homes that use hot water every day, a heat pump is usually the most economical option, and Bengaluru's mild weather lets it run efficiently all year. Where terrace space and sunshine allow, a solar water heater with heat-pump backup also works well. We size the system to your household or block.

Do you install and service Devyami systems in Bengaluru?

Yes. Tell us about your building, society or factory and our engineers design the system around Bengaluru'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.
