Water treatment plants, water supply schemes, reservoirs and pump houses under one SCADA, delivered inside EPC packages for government water supply schemes.
Raw water is pumped from the source, aerated, dosed with coagulant and flash mixed, settled in a clariflocculator, filtered, chlorinated and stored in a clear water reservoir before distribution. Each stage depends on the one before it. Our SCADA ties them together and gives the operating authority the quality and energy records it needs.
The Naidupet 10 MLD plant as an example: follow the numbers from the summer storage tank to the three supply headers. The control room at the top sees every stage, and the cards say what the PLC and SCADA do at each one.
Intake pumps SST-P-01 and SST-P-02 lift raw water from the summer storage tank over a cascade aerator into a measuring channel with a weir.
We automate:Duty and standby selection, run hours per pump, dry-run protection, and raw water flow, pH and TDS (RW-FIT-101, RW-pH-101, RW-TDS-101) with high and low alarms.
Alum solution from tank T-01-A or T-01-B, each with its own agitator, flows by gravity into flash mixer AG-01, which spreads it through the raw water.
We automate:Dosing paced to inlet flow and trimmed to turbidity and pH, tank level interlocks from the AL-LS switches, and agitators blocked when a tank is low or inlet flow is lost.
Paddles FL-01 to FL-04 stir the dosed water gently so floc forms in the centre zone, the floc settles in the outer zone, and the bridge DR-01 scrapes sludge to a sump.
We automate:Paddle and bridge drive supervision with run feedback and trip alarms, desludging timers, and sludge pumps SP-01 and SP-02 sent to the nala.
Four rapid gravity filters, RF-01 to RF-04, pass the settled water down through sand and gravel. A dirty bed is washed with air and then water from the roof tank.
We automate:A wash requested on head loss or run time, the 5-step backwash sequence with air scour, one bed at a time, roof tank filling by WT-P-01A/B, and travel alarms on all 22 MOVs.
Filtered water is chlorinated and held in a baffled contact tank long enough for the chlorine to act before it goes to storage.
We automate:Residual chlorine trim from CW-RCL-101, filtered flow, pH and TDS (FW-FIT-102, FW-pH-102, FW-TDS-102), with IS 10500 limits set as the alarm limits.
Treated water collects in the pure water tank, and three pump pairs deliver it into the SEZ, Naidupeta and Athivaram headers, each with its own flow meter.
We automate:Duty rotation per header, daily and monthly header totals from PH-FIT-01 to 03, and dry-run protection for every pump from the FW-LS-101 tank level.
PLC-01 and an iFIX SCADA station run the whole plant from one room, with remote overhead tanks and pump houses linked by RTU over 4G.
We automate:Alarms with acknowledgement, trends kept in the historian, the daily report of volume, quality and energy, and status from the remote sites.
The screens we designed for the Naidupet plant: one overview, one screen per area, alarms, trends and the daily report.

Intake to clear water reservoir under one SCADA: dosing against live analyzers, automatic filter backwash, quality and energy reporting.
PLC panels, marshalling and SCADA workstations built to our drawings, wired, tested and documented before dispatch.
Annual maintenance for running iFIX and GE PLC systems, and migration of legacy control systems without a long shutdown.
Automation and SCADA for the treatment plant in SRR Projects' government water supply EPC package.
PLC and SCADA across the treatment train: intake pumps, chemical dosing trimmed against online analyzers, clarifier and filter sequencing with automatic backwash, chlorination and clear water reservoir control, with daily quality and energy reports.
Yes. We supply the complete instrumentation, PLC and SCADA package to EPC contractors on municipal and rural water supply projects, from tender stage sizing to commissioning and handover. The Naidupet WTP for SRR Projects is a current example.
Yes. Remote sites report through RTUs or industrial 4G routers so tank levels and pump status appear on the same SCADA as the treatment plant.
