History of Tarbela Dam

Tarbela Dam is one of the world’s largest earth and rock filled Dam.

Greatest water resources

The Dam is built on one of the World’s largest rivers – the Indus known as the “Abbasin” or the father of rivers

History of Tarbela Dam

General consultant of WAPDA is HAZARA ENGINEERING COMPANY

The World Bank accepted Tarbela Dam Project in 1965

Built between 1968 and 1976

Project Constrain

• Cost The total cost of project including power

units (1-14) amount to US $ 2.63 billion.

• Time– 8.3 year’s

The Project Main Feature Project Consists of a 9,000 (2,743 meters) long.

spillway capacity 6.5millan cuescs

The dam is 469 feet (143 m) high.

The Dam is 8,997 feet (2,743 m) wide at its crest.

The total spillway capacity is 1,500,000Reservoir Aria 80km

Tunnels

• Total number of Tunnels 4

• Length half mile

• Tunnel 1, 2, 3 for power generation and tunnel 4 for irrigation

Spillway

• Two Spillway (Service spillway auxiliary spillway)

• Spillway is flood routing structure• Spillways capacity is 1500,000 cusecs

Spillway

• Service spillway has 44% of total capacity• Discharge capacity of service spillway is

650,000 cusecs.• Discharge capacity of auxiliary spillway is

850,000 cusecs.

Power Generation

Four power units of 175 MW installed on each of the tunnels 1, 2, and 3.

The project has thus been enhanced from 2100 MW, as originally planned to 3478 MW.
