SDP Sabarimala ENVTL -M and M festival 1202- Operation and overhauling of Sewage Treatment Plant for monthly pooja and temple opening days from September 2026 to October 2027 including M and M festival of 1202 ME

OD61068/2026-2027:Supply, installation, and calibration of level sensors in the equalization tank, ensuring accurate and reliable measurement of liquid levels under varying operating conditions. The task also involves integrating these sensors with the existing SCADA (Supervisory Control and Data Acquisition) system so that real-time readings are available for monitoring, alarms, and process control. Proper installation will cover mechanical mounting, electrical connections, and signal cabling, followed by calibration to verify precision and consistency of measurements. Once integrated, the SCADA system should display and record sensor data, Additionally, the supplied sensors will be backed by a minimum 12 month manufacturers warranty, covering defects in materials and workmanship to guarantee performance and reliability.

OD61069/2026-2027:Supply and installation of starter for 35 hp three-phase submersible pump fully automatic star delta (FASD) unit designed for 415v, 50hz ac operation. The starter must be equipped with an adjustable thermal or electronic overload relay, typically within the 30a to 50a range, and must include a triple pole mcb or mccb rated at 100a for robust short-circuit protection. Essential safety features should include a built-in single phasing preventer (spp), phase reversal protection, and under-voltage/over-voltage cutouts to safeguard the motor during power fluctuations. The unit must be housed in a durable, powder-coated, dust-proof enclosure with an ip54 or higher rating, featuring integrated monitoring instruments such as an ammeter and voltmeter. All components must comply with IS/IEC 60947 standards and be backed by a minimum 12-month manufacturer warranty

OD393155/2025-2026:Labour charges for checking and carrying out necessary repairs of the SCADA system at STP Sabarimala include comprehensive inspection and servicing to ensure perfect and trouble free operation of all switches, pumps, motors, valves, and visual monitors connected to the treatment plant. The scope covers preventive maintenance such as calibration of sensors, troubleshooting of alarms, rectification of communication faults, and updating of SCADA software as required. It also includes immediate attention to breakdowns of equipment controlled via SCADA, correction of logic errors, and verification of interlocks and safety circuits. The rate further covers all software related repairs and continuous support throughout the festival period, ensuring uninterrupted and reliable functioning of the STP under the direction of the Engineer in Charge.

OD393157/2025-2026:Blower Overhauling charges as per the direction of Engineer in charge, including dismantling, inspection, cleaning, replacement of worn parts, changing of lubricating oil, changing of belts, reassembly, and testing to ensure proper performance

OD393158/2025-2026:Blower Starter Service (Blower 2 & 3) 75 kW / 100 HP, including isolation, inspection, cleaning, servicing/replacement of contactors, relays, overload protection, wiring checks, lubrication, testing, commissioning, and submission of service report as per the direction of Engineer-in-Charge.

OD393159/2025-2026:Decanter movement mechanism and gear system overhauling & servicing charges, including dismantling, inspection, cleaning, replacement of worn parts, lubrication with grease , reassembly, testing, and commissioning as per the direction of Engineer-in-Charge

OD393163/2025-2026:Submersible Pump Set (35 HP) Overhauling & Servicing Charges including dismantling, inspection, replacement of worn parts, electrical testing, reassembly, installation, and commissioning

OD62788/2026-2027:Overhauling of safety level sensors which involves inspection of the magnetic sensor and control relay for wear, damage, or malfunction; cleaning of the sensor and relay components to remove dust, debris, or contaminants; testing of the 24 VDC PNP NO magnetic sensor and the 14-pin control relay with relay base to verify proper functionality; and replacement of faulty parts, including the relay or sensor, with compatible components as required.
