of Santa Ana Section 5: Design and Performance Provisions Section 5: Design and Performance Provisions Section 5 of this SSMP addresses the requirements included in Attachment D-5 of the Order. The requirements state: Design and Performance Provisions: The Plan must include the following items as appropriate and applicable to the Enrollee's system: (a) Updated design criteria, and construction standards and specifications for the construction, installation, repair, and rehabilitation of existing and proposed system infrastructure components, including but not limited to pipelines, pump stations, and other system appurtenances. If existing design criteria and construction standards are deficient to address the necessary component -specific hydraulic capacity as defined in Section 8 (System Evaluation, Capacity Assurance and Capital Improvements) of the Order, the procedures must include component - specific evaluation of the design criteria. (b) Procedures and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances. The City has established Sewer System Standard Plans, Standard Specifications and Design Guidelines requiring that all newly constructed, newly installed, repaired, and rehabilitated sanitary sewer pipelines, pump stations, and other equipment and appurtenances, be designed and constructed in accordance with the City's established standards. 5.1 Updated Design Criteria and Construction Standards and Specifications The City's established standards contain design and construction standards and specifications for the installation of new sanitary sewer systems, and other appurtenances, and for the rehabilitation and repair of existing sanitary sewer infrastructure. The City's Specifications by reference incorporate the American Public Works Association Standard Plans and Specifications for Public Works Construction ("Green book"), which helps ensure proper design and construction of sewer facilities. Additionally, the City has standardized its use of equipment in the pumping stations for ease of maintenance and replacement. This includes the pumps, liquid level indicators, electrical components, valves, piping and radios. The City also uses cured -in -place pipe lining technology where these methods are cost effective and practical to supplement traditional replacement and rehabilitation methods. The City has adopted the American Public Works Association Standard Specifications for Public Works Construction ("Greenbook") as its standard specification for sewer projects. The Greenbook specifications for pipeline rehabilitation are used as the standard for City projects. 2025 5-2
