WB Irrigation Schedule of Rates
About West Bengal Irrigation & Waterways Department
West Bengal's distinct geography — Hooghly delta, Sundarbans, North Bengal hills, plus extensive irrigation networks (Damodar Valley, Mahananda, Teesta) — drives a substantial Irrigation & Waterways Dept civil portfolio. The dept handles canal lining, embankment construction (critical for flood-prone delta), dredging operations on Hooghly and Mahananda, river-training works, and dam-allied civil works. Its SOR is separate from WB PWD's general civil SOR and WB PHED's water-supply SOR — covering items unique to irrigation/water-resources civil scope. Engineers in Kolkata, Howrah, Burdwan, Murshidabad, Cooch Behar, Jalpaiguri reference this SOR for irrigation-funded projects.
Frequently Asked Questions
How is WB Irrigation SOR different from WB PWD?
WB PWD covers general civil works (buildings, roads). WB PHED covers water-supply schemes. WB Irrigation & Waterways covers irrigation-specific civil — canal lining, embankments, dredging, river training, dam-allied works. All three are distinct departments with separate SORs.
What's covered in dredging rates?
Hooghly and Mahananda navigation dredging; Sundarbans creek dredging; reservoir desilting; canal-bed restoration. WB has one of India's most extensive dredging programmes due to delta sedimentation.
Are embankment rates seasonal?
Yes. Construction window is October-May; June-September monsoon makes earthwork unviable. SOR builds in seasonal productivity factors. Emergency embankment repairs during/after cyclones are tendered with crisis-priced premiums.
Does Damodar Valley Corp use this SOR?
DVC is a separate central body. WB Irrigation handles the WB share of DVC-related canals + embankments using this SOR. DVC's own civil works follow CPWD DSR.
