The project will increase the public health, safety, and local amenity of school-goers and local residents.
The new facility will replace four aging wastewater systems (the Webster Elementary OWTS, Our Lady of Malibu OWTS, Malibu Colony Shopping Center treatment plant, and County-operated plant at Vista Pacifica St) that serve the two schools and the multifamily residences across from the site. Faculty, students, and residents have complained of odors and daylighting of sewage from failing systems for years. The RWQCB notified the schools that they must meet new water quality standards because of either failing or inadequate treatment in the aging onsite systems.
The new facility will have state of the art wastewater treatment equipment that will be fully covered, or enclosed within buildings. All treatment facilities will include full odor control. None of the four existing treatment systems in the vicinity have these features. The treatment facility will have an increased factor of safety because standby equipment and standby power will be built into the treatment systems to allow uninterrupted treatment in the event of equipment or power failure. This degree of safety is not provided by the existing treatment facilities in the area.
The treatment facility will be further away from the school and local residences than the County treatment plant, which is not odor scrubbed, is not fully enclosed or covered, and provides little visual screening of its process tanks.
The closest example of a treatment plant being sited in this type of location is the County treatment plant, which treats flow from the nearby condominiums. As stated previously, this plant is closer to the condominiums than the proposed new treatment plant. Los Angeles’ Hyperion wastewater treatment plant, which treats 800 times the projected flow of the Malibu plant, is within 400 feet of residential structures.
