1.0 NAME OF WORK
Geo-technical Investigation including Deep Drilling for Rock Coring using Diamond Bit
Double Tube Core Barrel along proposed link canal and CD structures in Ambica –
Narmada reach of Par – Tapi - Narmada Link
2.0 GENERAL INFORMATION
2.1 THE PROJECT
The Par – Tapi – Narmada link comprises the following components:

Construction of Jheri dam across river Par in Peint taluka of Nasik district of
Maharashtra.

Construction of Mohankavchali dam across river Par near village
Mohankavchali in Dharampur taluka of Valsad district in Gujarat State.

Construction of Paikhed dam, across river Nar, the main tributary of river par near village Paikhed in Dharampur taluka of Valsad district.

Construction of Chasmandva dam across river Tan a tributary of river
Auranga in Dharampur taluka of Valsad District.

Construction of Chikkar dam across river Ambica near village Chikkar in
Ahwa taluka of Dang district in Gujarat State.

Construction of Dabdar dam across river Kapri, a tributary of river Ambica near village Dabdar in Ahwa taluka of Dang district in Gujarat State.

Construction of Kelwan dam across river Purna near villages Kelwan and
Kakarda in Ahwa taluka of Dang district in Gujarat State.

Construction of Three diversion weirs one each in the downstream of
Paikhed, Chasmandva and Chikkar dams as the hilly terrain does not permit the link canal to take off from the dam sites.
4


Out of six power houses, four power houses are located at the toe of Jheri,
Paikhed, Chasmandva and Chikkar dam. Remaining two power houses located at the falls of the feeder canals connecting Dabdar and Kelwan reservoirs to the main canal of Par-Tapi reach.

A 400 km long canal (including two tunnels of 5.0 km & 0.5 km long)
The objective of the Par-Tapi - Narmada link is to divert the surplus water from west flowing rivers between Par & Tapi to water deficit areas in North Gujarat
(Saurashtra & Kutch) by substitution. The project proposes to provide enroute irrigation to 0.52 lakh ha and takes over 1.17 lakh ha of Sardar Sarovar Project command and the water thus saved in Narmada main canal can be used to extend irrigation in Saurashtra and Kutch.
The National Water Development Agency had prepared the Feasibility Report of
Par
– Tapi – Narmada link and the web friendly version of this Feasibility Report is available on NWDA’s website http://www.nwda.gov.in
