IID Water Department facilitates the transfer of raw Colorado River water for agricultural, as well as industrial, rural-residential and municipal non-potable use in the Imperial Valley. An extensive drainage system is also maintained by IID Water Department that allows for agricultural runoff.

IID Water Department is comprised of five sections: Administration, Resources Planning and Management, Engineering Services, Water Operations, and Construction and Maintenance. These five sections allow IID to meet the water needs of our customers today, while implementing practices and procedures that will conserve and protect Colorado River water for generations to come.
