Phase 3 Construction at the Wastewater Treatment Plant Upgrade is Underway

Construction of the Wastewater Treatment Plant upgrades continue to make great progress. The contractor has completed the installation of the storm drain improvements. Phase 1 and Phase 2 construction is complete.

Phase 3 construction is underway, and activities include construction of the new treatment facilities, the administration building, and the new warehouse. The framing of the exterior of the administration building is completed and installation of interior utilities and walls is nearing completion. The building is anticipated to be completed by April 2023. The framing of the warehouse has begun. The contractor has poured approximately 90 percent of the 32,000 cubic yards of concrete for this project. Electrical switchgear, transformers, and four generators for the new electrical building are being installed. The contractor has installed two new generators in the existing main structure as well as completed modifications to the refueling system. Installation of pipes and pumps is ongoing in and odor control equipment is being installed.

Ongoing construction activities include formwork and rebar, concrete pours, installation of pipe, and electrical work for the various treatment structures. Miscellaneous site work, including installation of the membrane permeate pipe and secondary effluent pipes, and electrical duct bank are ongoing.

The City is committed to minimizing the effects of construction on the neighboring community and will be using several noise reduction and control measures during this work.

Dale Avenue Pump Station Project- Emergency Standby Generator Installation

The City has been constructing sewer infrastructure improvements at the Dale Avenue pump station, and will now need to install an emergency standby generator. The pump station is vital for the operation of the City’s sewer system and must remain operational 24/7. The purpose of the new emergency standby generator is to provide a power supply to the pump station in the event of a power outage. The existing generator requires replacement to be compliant with air quality requirements. It will be installed east of the pump station building, as shown in the image below.

The upcoming emergency standby generator installation will consist of site preparation, excavation, foundation piles, concrete pours, generator placement, wiring, and piping installation. Construction of the generator is anticipated to start in Spring 2023 and last a few months. The proposed site plan and equipment elevations can be seen here.

The City hosted a virtual neighborhood meeting on September 20, 2022, and provided the community with the details of upcoming work associated with the emergency standby generator for the Dale Avenue Pump Station project. The virtual meeting provided details of the work related to the emergency standby generator and included construction schedules and what the community can expect. You can view a recording of the meeting here, or view the presentation by clicking here.

During the installation of the generator, residents can expect to experience some short-term inconveniences, such as noise and vibration due to trucks and equipment operating around the sites. Mitigation measures will remain in place to minimize the effects of the project on residents.

A Basin (North Basin) Sewer Rehabilitation Project Construction is Progressing

Map of A BasinThe purpose of the A Basin Sewer Rehabilitation Project is to repair and rehabilitate existing sanitary sewer pipelines and manholes. This project is part of the City of San Mateo’s rehabilitation of the overall wastewater collection system.

Construction to repair sewer pipes and manholes began in August 2022 and will continue until summer 2023. Most of the work will occur in City streets, including some high-traffic areas. Several different methods of construction, such as open-cut trenching or different trenchless technologies, will be used based on the current conditions of each site and to reduce potential impacts on the public.

Mitigation measures will be in place to minimize the effects of the project on residents, businesses, commuters, and others. Notifications will continue to be sent ahead of construction to alert businesses, property owners, and occupants.

For more information, please call 1-650-727-6870, or email info@CleanWaterProgramSanMateo.org or contact CWP Project Manager Laura Webb at 1-650-522-7322 or lwebb@cityofsanmateo.org.

B Basin (West Basin) Sewer Rehabilitation Project is in Design

As part of the City of San Mateo Clean Water Program, crews performed Closed-Circuit Television (CCTV) inspections for the B Basin project. Crews utilized a remote-controlled camera to help the City check the condition of pipes and obtain information that enables the City to identify problem areas in the collection system. The results of the CCTV will help the City and its engineers with the design of the project.

Notifications will continue to be sent to residents and businesses prior to the start of work, and the contractor will provide additional notices two to three days prior to work starting in your area.

For more information, please call 1-650-727-6870, or email info@CleanWaterProgramSanMateo.org or contact CWP Project Manager Laura Webb at 1-650-522-7322 or lwebb@cityofsanmateo.org.

C Basin Sewer Video Investigations are Complete

Progress Continues on UFES Project

The UFES project continues to make great progress! As of November 22, 2022, approximately 8,500 cubic yards of concrete have been poured at the San Mateo County Event Center site. The walls of the underground concrete structure are nearing completion. The team will soon begin preparation work necessary ahead of a series of pours that will build the roof of the structure.

Construction continues on the nearby electrical building at the Event Center site and the diversion structure on South Delaware Street near the intersection with Saratoga Drive.

The ongoing pipeline work along South Delaware Street will begin to ramp down later this season and into the winter; several of the pits along Delaware Street will be backfilled and restored in segments during the coming months.

More restrictive lane closures were implemented along Saratoga Drive in the vicinity of the San Mateo County Event Center.

Please watch for traffic signs, which are placed in specific areas to provide direction and ensure the safety of drivers.

Approved work hours are as follows:
San Mateo County Event Center Site: 7 a.m. – 7 p.m.; Saratoga Drive: 7 a.m. – 5 p.m.; South Delaware Street: 7 a.m. – 5 p.m.

*Construction schedules and traffic patterns are subject to change.
