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.

Construction Methods

Open Trench

Higher costs and complexity/greater traffic and neighborhood impacts

Pipe Bursting

(underground construction)

Lower costs and complexity/fewer neighborhood impacts

Jack and Bore

Required for Browning Avenue segment passing under the I-5 freeway

Pipe Example

  • Replacement sewer pipes will be upsized for continued reliability and future growth capacity

  • Sizes range from 8 inches to 21 inches in diameter
