Approved for March 31, 2026 calendar
EXECUTIVE SUMMARY
The Public Works Department (PWD) is undertaking a trenchless pipeline rehabilitation program for sewer and storm drain infrastructure to maintain reliable service and protect public health. To accomplish this, staff are seeking to procure a qualified contractor through a competitive bidding process and execute a three-year on-call contract to perform various types of lining on sanitary sewer and storm drain pipelines, with an option to extend the contract for up to two additional years.
The intent of this item is for the City Council to adopt the project plans and specification, and authorize the City Clerk to advertise for bids.
RECOMMENDATION
Approve the resolution to adopt the plans and specifications for the 2026 Sewer Lining Project and On-Call Sewer and Storm Drain Lining Services, and direct the City Clerk to advertise for bids.
ANALYSIS
The City of Glendale owns and maintains approximately 350 miles of sanitary sewer mains and 26 miles of storm drain lines. Much of the city’s sanitary sewer system was constructed in the early 1900s, when the city was first incorporated, and many mains are now over 100 years old. Due to their age and material composition, these pipelines are subject to corrosion, cracking, and structural deterioration, requiring ongoing rehabilitation to maintain system reliability and protect public health and safety. 5e2

While ownership and maintenance responsibility for many reinforced concrete storm drain lines has been transferred to the Los Angeles County Department of Public Works, the city continues to maintain certain reinforced concrete pipe segments, as well as corrugated metal pipe (CMP) storm drain lines constructed in the early to mid-20th century. CMP lines are not transferable to the county and remain the city’s responsibility, requiring continued maintenance and rehabilitation as they age.
PWD crews routinely perform cleaning and closed-circuit television (CCTV) inspections of the city’s sewer and storm drain infrastructure and have documented deficiencies requiring repair and rehabilitation. Based on inspection findings, staff evaluated pipe conditions and developed plans and a specification to address both ongoing system rehabilitation needs and localized deficiencies requiring timely repair.
Following completion of CCTV inspections and condition assessments, staff identified segments of the sanitary sewer system where trenchless rehabilitation is appropriate.
As part of the city’s ongoing rehabilitation strategy, sewer lining is an effective method to address many of the documented deficiencies by creating a new structural liner within the existing pipe, restoring structural performance, and improving system reliability with minimal surface disruption to the streets and nearby properties.
The proposed sewer lining work will include sectional (partial length) and full-length lining and associated appurtenant work within the public right-of-way and easements.
These improvements will address the sewer pipeline defects, reduce infiltration and the risk of failures, and extend the service life of the sewer network while minimizing impacts to traffic, residents, and businesses.
Project plans and a specification have been prepared to support trenchless rehabilitation methods, including Cured-In-Place Pipe (CIPP) lining for this project. The proposed project will allow the city to competitively procure a qualified contractor to provide services for the following two phases of the work:
Phase I, 2026 Sewer Lining Project: Planned trenchless rehabilitation of identified sewer segments at various citywide locations per Plan Nos. 3-1590 and 3-1595.
Phase II, On-Call Sewer and Storm Drain Lining Services: Unit-price-based, as- needed trenchless pipeline rehabilitation and repair services identified through CCTV inspections or operational needs during the contract term. This portion of the work will be authorized by the city on an as-needed basis through the contract term, and the contractor may be directed to perform either planned rehabilitation or unanticipated repairs on as-needed basis.
Upon City Council approval of the contract award at a future meeting, the agreement will be for an initial three-year term from the date of certification by the City Manager, with an option to extend for up to two additional years, subject to satisfactory performance.

A copy of the project plans and specification are available for public review in the City Engineer’s office and on the city’s website.
Competitive Bidding Process
To ensure competitive bids, the city will advertise the project on multiple plan holders’ websites, which publish project bidding documents and distribute the information to their extensive network of contractors and construction industry contacts.
The project will also be advertised in a local newspaper, the Glendale Independent, prior to bid opening, as well as on Bidnet Direct, which is a web-enabled data service to the public sector for the dissemination of the building and construction project proposals to their large number of member contractors and consultants. Finally, the project bidding documents will also be posted on the city’s website.
STAKEHOLDERS/OUTREACH
Outreach for the 2026 Sewer Lining Project and On-Call Sewer and Storm Drain Lining Services will be tailored to meet the needs of each specific task and impacted community. Outreach efforts will be implemented on an as-needed basis. Depending on the project needs and resources availability, variety of tools and methods can be utilized to keep the public informed and engaged.
A dedicated project website will be maintained through the City of Glendale domain to provide project updates, maps of affected areas, an introduction to the project team, FAQs, and staff contact information. The website will serve as a central resource for residents seeking detailed information or wishing to provide feedback.
In addition, personalized outreach may be conducted through one-on-one meetings with directly impacted residents and businesses. This allows staff to address specific concerns, explain the scope of work, and discuss mitigation measures for potential inconveniences such as road closures, water service interruptions, or noise disturbances.
To reach a broader audience, the project may also utilize social media platforms such as Facebook and Instagram, including location-based posts or ads, to provide updates, traffic advisories, reminders about key dates, and links to more detailed resources on the project website.
FISCAL IMPACT
There is no fiscal impact associated with this report. The current engineer’s estimate for the construction of this project is $5,500,000, which was not included as part of the FY 2025-26 budget. Therefore, staff will request appropriation from the Sewer Fund (5250) at the time of the contract award based on the lowest responsive bid received from a responsible contractor.

ALTERNATIVES TO STAFF RECOMMENDATION
Do not approve the resolution adopting the plans and specifications for the 2026 Sewer Lining Project and On-Call Sewer and Storm Drain Lining Services. Doing so, however, will impair the city’s capacity to make timely sewers and storm drain repairs which protect public health and safety.
