The Pulichintala Project is a multi-purpose water management project for irrigation, hydropower generation, and flood control in the state of Andhra Pradesh, India, named after the prominent civil engineer, Kanuri Lakshmana Rao.{{Cite news |last= |first= |date=2023-07-15 |title=‘Father of Irrigation’ K.L.

History
In 1911, British engineer Col. Ellis proposed an irrigation project upstream of the Prakasam Barrage. At the time, the British government showed little interest in the proposition.{{Cite news|last=Jonathan|first=P. Samuel|date=2013-12-08|title=Pulichantala dedicated to nation|language=en-IN|work=The Hindu|url=https://www.thehindu.com/news/national/andhra-pradesh/pulichantala-dedicated-to-nation/article5434456.ece|access-date=2021-07-14|issn=0971-751X}} Later, the Raja of Muktyala led the push for the Pulichintala Project with the help of Moturi Satyanarayana and K.L Rao.{{Cite book|last=Rao|first=K.

On 7 December 2013, the project was ready for a trial run,{{cite web |title=Pulichintala project on August 15 |url=http://www.deccanchronicle.com/130710/news-politics/article/pulichintala-project-august-15 |url-status=dead |archive-url=https://web.archive.org/web/20130715033948/http://www.deccanchronicle.com/130710/news-politics/article/pulichintala-project-august-15 |archive-date=2013-07-15 |website=Deccan Chronicle}} and it started impounding water in August 2014.{{cite news |title=Engineers complete trial run of Pulichintala Project |url=http://timesofindia.indiatimes.com/city/hyderabad/Engineers-complete-trial-run-of-Pulichintala-Project/articleshow/40313223.cms |access-date=16 August 2014 |website=The Times of India|date=16 August 2014 }} It was fully completed in September 2018.{{Citation|title=AP Govt Plans to Develop Pulichintala Project as Tourist Place {{!}} Pulichintala Project {{!}} AP24x7|url=https://www.youtube.com/watch?v=EdKT0BimzXI|language=en|access-date=2020-01-19}} The total cost of the project exceeded Rs.1850 crores.{{citation needed|date=November 2022}}
Project
The irrigation facility is in the Pulichintala village, located in the Palnadu district near the Krishna River.{{cite web|url= http://www.apgenco.gov.in/viewHTMLpage.asp?lfile=uploadedfiles/Pulichinthala.htm |title= Pulichintala project progress report, APGenCo |access-date=15 May 2013}} It is between the Vykuntapuram barrage (near Amaravati) and the Nagarjuna Sagar dam.{{Cite news|url=https://www.thehindu.com/news/cities/Vijayawada/naidu-lays-foundation-stone-for-barrage-across-krishna/article26265021.ece|title=Naidu lays foundation stone for barrage across Krishna|last=Srinivas|first=Rajulapudi|date=2019-02-14|work=The Hindu|access-date=2019-03-01|language=en-IN|issn=0971-751X}} It has a 30 Tmcft live storage capacity to impound river floodwaters generated from the catchment area located downstream of Nagarjuna Sagar Tail Pond. The project reservoir provides a water supply to the downstream Prakasam Barrage that then can be sent out through the Pattiseema lift/Polavaram irrigation canal during monsoon months.{{cn|date=August 2023}}
The Vellatur lift irrigation scheme (constructed near {{Coord|16|42|44|N|80|00|29|E|name=Pulichintala lift scheme}}), irrigates 13,000 acres in the Nalgonda district. It draws water from the Pulichintala reservoir.{{cite web |title=KCR, Harish Rao lying on Pulichintala issue: Uttam |date=27 June 2016 |url=http://www.siasat.com/news/kcr-harish-rao-lying-pulichintala-issue-uttam-979080/ |access-date=28 September 2016}} The lift can pump water from {{convert|120|ft|m|0}} MSL when the reservoir's gross storage is as low as 4 Tmcft. The proposed Yadadri Thermal Power Plant would also draw water from the reservoir.{{cn|date=August 2023}}
Godavari Penna River Linking
{{Main articles|Vykuntapuram barrage}}{{Confusing|section|reason=there are a lot of confusing jargon and unclear explanations|date=June 2022}}
The Godavari Penna River linking project was constructed to stabilize the existing irrigated area under the Nagarjuna Sagar right canal. The new lift would have greenfield alignment, and its first phase consists of five-step ladder pumping stages that transfer 7,000 cusecs of Godavari River water from Prakasam Barrage to deliver 73 Tmcft of Godavari water into the Nagarjuna Sagar right canal near Nekarikallu.{{Clarify|date=June 2022|reason=Where do the cusecs go? Where did the TMCs come?}}
With FRL 25M the newly created Vykuntapuram Barrage pond will have backwaters beyond Pokkunuru up to the toe of the Pulichinthala Project. It is more economical to construct the first stage pump house to lift water from the Prakasam Barrage backwater into the newly created Vykuntapuram Barrage pond and the second Lift stage from the Vykuntapuram Barrage pond to the existing K.L Rao Sagar Pulichintala Project and later lift Stages from K.L Rao Sagar to Nagarjuna Sagar right canal. It will shorten the length of this lift project canal, Pressure Main and fewer lift stages and also enable to lift of water up to Srisailam Project via the existing Reversible Reverse turbine pump houses in Nagarjuna Sagar Dam and its tail pond project. It is even more economical if the construction of a new gravity canal from Ibrahimpatnam to Vykuntapuram Barrage pond to deliver the Polavaram right main canal/ Budameru diversion canal waters directly into the Vykuntapuram barrage pond since Polavaram right main canal level is 33 m MSL at Ambapuram hill near Vijayawada.{{cn|date=August 2023}}
A low-level, lift canal from the Krishna river located near {{Coord|16|42|50|N|80|08|24|E|type:landmark_region:IN-AP}} at {{convert|20|m|ft|0}} MSL 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 the extension of Nagarjuna Sagar right bank canal connecting Kandaleru feeder canal / Somasila Dam reservoir 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 lowlands along the Krishna river up to Pulichintala dam.{{cite web|url= https://www.deccanchronicle.com/nation/current-affairs/070916/pulichintala-a-capital-saviour.html |title= Pulichintala, a capital saviour|access-date=7 September 2016}}
