The command area of this project is distributed over Kollam, Pathanamthitta and Alappuzha district and coveres Pathanapuram, Kottarakkara, Kollam, Kunnathur, Karunagappally, Adoor, Mavelikkara and Karthikappally Taluks. The project was planned to irrigate net cultivable command area of 61630 Ha. During the course of execution few canals including Kayamkulam Branch canal were dropped and now this project is benefited for a net cultivable command area of 53514 Ha in 92 villages. Head works is completed during 1986. Left and right bank main canals are fully completed. Right bank main canal partially commissioned during 1986 and left bank main canal during 1992.

Main components of the project:

1. Dam at Parappar:- Reservoir is formed by constructing a gravity type masonry dam across Kallada river at Parappar near Thenmala and a saddle earthen dam at Pallamvetty. Gross storage capacity of the reservoir is 504.92 Mm3.

2. Pick up weir at Ottackal : A pick up weir just 5 Km down stream of dam is provided at Ottakkal. This has got a capacity of 17 Mm 3. The main canals (RBC and LBC) off take from the weir. The tail race water from the power house provided just at the downstream of the dam is collected at weir and used for Irrigation. When there is no power generation, the irrigation valves are opened and water collected at Ottackal.
