TARAKARAMA LIFT IRRIGATION SCHEME

Preamble

The Tarakarama lift Irrigation scheme in Krishna district is initially proposed to provide irrigation facilities to an extent of 56,000 acres located in 64 villages under 8 upland mandals by utilizing return water from Vijayawada Thermal power station in Budameru diversion channel. Total extent under TRLIS was restricted to 13,820 acres as construction of Indira Sagar Polavaram Right Main Canal is taken up and the balance ayacut can be covered under Indira Sagar Polavaram Right Main Canal. The extent under Left Main Canal was 9000 acres, and the ayacut under Right main canal is 4820 acres.

Left Main Canal

The length of TRLIS left main canal is 6.60 Kms. This canal runs by gravity and covers an ayacut of 3710 acres by direct OT sluices, 790 Acres by Kowluru sub lift at K.M. 2.80, 2000acres by Velagaleru Sub lift and 2500 Acres by Kotturu sub lift at Km. 6.60

Right Main Canal

The length of TRLIS Right main canal is 11.60 Kms. The excavation of canal and construction of 4 pump houses was completed up to Km. 9.40. Beyond Km. 9.40, the canal is taken up by Gaddamanugu and Cheruvumadhavaram pressure main systems. The ayacut covered under these two sub lifts is 1867 acres (1367 acres Gaddamanugu + 500 acres Cheruvu madhavaram). These works are under progress, the Gaddamanugu pressure main work was completed and Cheruvu Madhavaram sub lift work is nearing completion.

So far Rs. 23.79 Crores of expenditure incurred and water was released to an extent of 8,210 acres under left main canal and 2,953 acres under Right main canal. The balance ayacut is 2657 acres.

The balance ayacut was covered as follows.

Left Main Canal

Under Kowluru sub lift 790 acres Work is completed and now Water is being given to Kowluru tank on trial run

Right Main Canal

Under Gaddamanugu pressure main 1367 acres Work is completed
Under Cheruvu Madhavaram sub lift 500 acres Work is in nearing completion. cost of balance work is Rs. 66 Lakhs

Total balance ayacut - 2657 acres

Transplantation: Transplantation for 11,000 acres completed against 11,163 acres for which IP created.
