Pulichintala Project is a multipurpose project serving irrigation needs, hydro power generation and flood control. It is a crucial irrigation facility for farmers of four coastal districts of West Godavari, Krishna, Guntur and Prakasam where irrigation facility for 13 lakh acres. It has 24 gates in all with balancing reservoir with a capacity of 46 tmcft at 175 feet (53 m) MSL full reservoir level (FRL).[2] The project started impounding the water in August 2014.[3] The cost of the project has exceeded Rs.1850 crores.

History

The project was first conceived in 1911 by British engineer Col Ellis. The foundation stone was laid by the then Chief Minister, N. T. Rama Rao on 13 November 1988 at a projected cost of 188 crores.[4] It was the first project to start under the ambitious Jalayagnam in the year 2004-05. which has been started by Y. S. Rajasekhara Reddy, the then chief minister of Andhra Pradesh. . It was opened on 7 December 2013 by Chief Minister of Andhra Pradesh, Kiran Kumar Reddy.[5] Pulichintala project is located in Nalgonda District, Telangana State.

Location

It is located in Pulichintala village in Guntur district across the Krishna River,[6] between Prakasam Barrage at Vijayawada and the Nagarjuna Sagar dam.

Storage

It has 30 Tmcft live storage capacity to impound the Krishna river flood waters generated from the catchment area located downstream of Nagarjunasagar Dam. This reservoir provides timely water supply needed by Prakasam Barrage minimising Krishna water wastage to the sea. Water to the Prakasam Barrage can be supplied from Pattiseema lift / Polavaram irrigation canal during monsoon months only when there is water shortage in Pulichintala reservoir.

Vellatur lift irrigation scheme (near 16°42′44″N 80°00′29″E / 16.71222°N 80.00806°E / 16.71222; 80.00806 (Pulichintala lift scheme)) with 13,000 acres irrigated area in Nalgonda district drawing water from the Pulichintala reservoir has been constructed.[7] This lift can pump water from 120 feet (37 m) MSL when the reservoir's gross storage is as low as 4 Tmcft. The proposed Yadadri Thermal Power Plant would also draw its water needs from the reservoir.

A low level lift canal from the Krishna river located near 16°42′50″N 80°08′24″E / 16.71389°N 80.14000°E / 16.71389; 80.14000 at 20 metres (66 ft) MSL in the downstream of Pulichintala dam will be executed to feed Godavari water diverted from Polavaram Dam to some of the existing command area (situated below 60 m MSL) under Nagarjuna Sagar right bank canal to facilitate extension of Nagarjuna Sagar right bank canal connecting to Kandaleru feeder canal / Somasila reservoir for serving irrigation needs in Prakasam, Potti Sriramulu Nellore and Chittur districts including Chennai drinking water supply. A branch from this lift canal is also extended up to Pulichinthala dam (FRL 53.34 m MSL) to store Godavari water in Pulichintala reservoir during drought years and to irrigate low lands along Krishna river up to Pulichintala dam.[8]

Power project

A 120 MW hydro electric plant (4X30 MW) owned by TSGENCO and first 3 units commissioned successfully. Erection of 4th unit completed and ready for commercial operation in August 2018. [9]
