Facilities Committee Meeting Minutes Page 4 March 9, 2010 Committee Recommendations: The Committee recommends that the City Council schedule approval of the Marina Boulevard Interchange Impact Fee to help fund improvements to the interchange. 3. Discussion Regarding Treatment Plant Condition Report Mike Bakaldin provided an overview of the Treatment Plant Rehabilitation project and provided the Committee with more information from a study that was presented in 2009 to both the Committee and at a Work Session. Public Works' presentation aimed at providing a brief description of each section of the project and reasons why we need to move forward now and why it is in the best interest of the City. Uche provided a historical overview of the sewer system. Prior to 1995, only $ l OOK was spent to maintain the plant. A study was done on the collection system to quantify the problem. Results showed that the system was not in good condition. A total of $20M was used to fix/maintain the system so far. A comprehensive analysis of the system was performed to determine what needs to be done quickly to avoid catastrophic failure, which will be presented next by Dean Wilson. Dean gave a presentation on the different aspects of repair to the treatment plant. He indicated that the treatment plant was the second in the Bay Area, and the first in the state to meet "fully treated" requirements. The plant operates 24x7, 365 days a year. The plant is self-sufficient and does not use General Funds to operate. Since it was built in the 1930s, the structures, units and equipment are old and have reached the end of their useful lives. He showed the existing conditions and the proposed rehabilitation. In 2002, Council agreed to own and operate the plant. At the time, $38M was identified for collection system improvements. So far, $20M has been spent to make repairs/improvements. Collection system staff doubled due to additional attention to preventative maintenance and sanitary sewer management and storm water programs, both of which are now mandated. There are 12 major project elements of the WPCP Rehabilitation Project; with the first six critical and must be done right away. Wet weather storage is mandated by 2011. With improvements, we will have the required capacity. Concrete in many areas need to be replaced. Secondary treatment has also reached its end of life. Seismically, it will not hold up. The existing electrical system has been around since 1958, and is old. The current transformer is a safety hazard and is susceptible to power surges. The primary clarifiers are old; built in 1938 and 1947. The Digesters need concrete repair and coating and the steel roof needs insulating. Basically, the structures, units and equipment are old and require replacement in order to avoid high risks. The City needs to avoid doing things on an emergency basis; there is a need to move forward now because the most critical facility is the most likely to fail. We need to go forward with replacing wet weather storage. We want to position ourselves to be on the list for SRF funding, which requires approval from Council.
