Project Overview
The East Orange County Water District plans to upgrade and enhance the reliability of sewer systems serving Tustin residents and in other areas being served. Originally installed in 1962, aging sewer lines are in need of repairs/replacements to ensure toilets, shower and sink drains remain operational. Sewer lines are also expected to be upsized, allowing for continued reliability with future population growth.
Following an extensive study, East Orange County Water District identified the following areas of the sewer system needing maintenance or replacement: Browning Avenue, Fallen Leaf Sewer, 6th Street, Clarissa Lane and Crawford Canyon.
