Santiago Aqueduct Commission

The Santiago Aqueduct Commission is a joint powers agency formed to finance, construct and maintain the V.P.

Members of the Commission include the Irvine Ranch Water District, El Toro Water District, Santa Margarita Water District, Trabuco Canyon Water District, the Municipal Water District of Orange County and Moulton Niguel Water District. 

Meetings take place at the Irvine Ranch Board Room located at 15600 Sand Canyon Avenue, Irvine, California 92618-3102.  Meetings are scheduled on a quarterly basis.
