Pakistan’s Water and Power Development Authority (WAPDA) invites expressions of interest from consultants for a sediment management study of the reservoir of the 3,478-MW Tarbela hydroelectric project on the Indus River. Responses are due February 16.
WAPDA already is taking expressions of interest by January 26 from consultants for detailed engineering design and tender documents for the 960-MW Tarbela 4th Extension project which would add another powerhouse to Tarbela. (HNN 12/31/08)
The current solicitation seeks a consultant to explore feasibility of safe and economical evacuation of sediment from Tarbela Reservoir, including its transport through the entire downstream river system.
WAPDA said the reservoir has gross capacity of 11.62 million acre-feet. However, 93 percent of river sediment is trapped in the reservoir. About 31 percent of the gross storage has been lost to sediment since operation began in 1974.
Pre-qualification documents may be obtained from the address below for 1,000 rupees in Pakistan or US$50 for foreign bidders, including delivery charges.
Expressions of interest are due by 2:30 p.m. February 16. WAPDA plans to prepare a short list of firms to be invited to submit proposals.
