Presented By: Patrick SullivanPublic Works Director

Item #4City Council Meeting

October 24, 2016

BACKGROUND

• On June 2, 2016, staff observed a sewer manhole overflowing at Corona and Alamo Heights Blvd

• Inspection revealed a section of sewer main in the 100 block of AH Blvd was impeded by root intrusion

• Due to the large amount of root growth the use of acid was declined

• The use of acid is a temporary fix for this type of problem; plus there is a concern for the health of the trees

BACKGROUND Cont.

• The City’s engineering firm, Freese and Nichols Inc. secured contractors’ low bids for the purpose of rehabilitating the main through a process called “Pipe Bursting”. Fees for service were $20,195.

• Once the project is completed the current ten (10”) inch main will be “up sized” to a twelve (12”) inch seamless main. This process will eliminate root intrusion in the future.
