WAPCOS has put out a ₹332.43 crore tender for earthwork repair and new distribution channels on the North Koel Right Main Canal in Bihar’s Aurangabad and Gaya belt, and bids are due by 6 October 2026.
Getting North Koel water to the fields
The North Koel Reservoir Project, shared by Jharkhand and Bihar, has a Right Main Canal whose distribution network has to reach farms across south Bihar. This package covers earthwork repair and construction of that distribution network, with its structures, in the Nabinagar, Amba, Aurangabad, Madanpur and Gaya divisions. WAPCOS Limited is running the tender for the Chief Engineer, North Koel Project, and the work location is given as Aurangabad, Bihar.
The rate is quoted as a percentage, and the portal lists a work period of 240 days. The pre-bid meeting took place on 24 September at WAPCOS in Gurugram, so check the portal for any clarifications it produced.
Plenty here for machine owners
Canal distribution work is spread out: many kilometres of minors and sub-minors, each with small structures like falls, outlets and crossings. The main bidder will need a large fleet in the field at once, and 240 days is a short window for ₹332 crore of earthwork, so hiring in local machines is almost certain. Owners around Aurangabad, Gaya and Daudnagar should get in touch with likely bidders early. If you work the state’s roads too, the Muzaffarpur Sitamarhi Sonbarsa NH-22 tender is live in north Bihar, and the Nandurbar canal pipe network tenders show what a similar distribution job looked like in Maharashtra.
Equipment the canal work calls for
Most of the effort is digging and shaping channels. Long-reach and standard excavators clean and re-section the canals, backhoe loaders handle smaller minors and structure pits, tippers move spoil, and rollers and plate compactors firm up banks and service tracks. Lining and structures bring in concrete mixers, and a motor grader helps keep the inspection roads usable.
