Panchayati Raj Department Bihar Potable Water Purification System Tender Katihar 2026 – ISI/ISO Standards & 27°C Recovery ARS/Fluoride Removal

Tender Overview

Panchayati Raj Department, Bihar seeks bids for a potable water purification system based on electro de-ionization ionization technology to serve Katihar, Bihar 854101. The contract contemplates a scalable quantity with a 25% quantity option during and after award, at contracted rates. Deliverables include installation and commissioning within scope, with inlet/outlet piping from raw water sources to the purification unit and to the purified water tank. Key differentiators include ISI/ISO certifications, and a comprehensive warranty option that may supersede catalog warranty. This procurement targets robust water treatment, arsenic/fluoride/chloride removal, and real-time monitoring features. The absence of a published estimated value and BOQ suggests a broad scope aligned to intended potable supply for rural/municipal use. Unique aspects include on-site installation, real-time TDS/pH displays, and integrated pre-filtration to support antiscalant usage where silica is ≤10 ppm and mica ≤100 ppm.
