Our self-performance model ensures quality control, <br />operational flexibility, and cost-efficiency with no reliance on subcontractors. <br />We also maintain full compliance with safety and traffic control standards, utilize <br />NASSCO-certified crews, and provide detailed GIS-integrated reporting. Our approach <br />emphasizes proactive coordination, minimal disruption to city infrastructure, and rapid <br />response capabilities, making us a dependable partner for both routine and task- <br />authorized system needs. <br />Approach <br />Presidio Systems, Inc. specializes in comprehensive cleaning and assessment of both <br />sewer lines and storm drain systems. Our operations are supported by a modern fleet of <br />hydro-vacuum (Vactor) trucks and high-pressure jetting equipment. For sanitary sewer <br />systems, we remove grease, roots, sediment, and obstructions using high-velocity <br />jetting nozzles and perform multiple passes to ensure optimal cleanliness before <br />detailed CCTV inspections. Our high-resolution, steerable cameras allow for thorough <br />defect identification and condition grading, aligned with PACP standards. <br />When blockages are encountered, crews reposition from alternate access points and, if <br />needed, deploy hydro-vac units to clear obstructions while maintaining flow continuity. <br />In addition to sewer line work, Presidio provides targeted storm drain maintenance <br />services, including hydro-vac cleaning of catch basins, inlet structures, and drainage <br />pipelines. We remove debris, sediment, floatables, and leaf buildup from inlets and <br />basins to maintain clear flow paths and reduce the risk of flooding or ponding during <br />storm events. For storm line assessment, we perform PACP video inspections and <br />documentation of pipelines to support infrastructure planning and GIS-integrated <br />reporting. <br />Our dual focus on sewer and storm systems ensures that cities receive coordinated, <br />efficient service that enhances system reliability and public safety. <br /> <br /> <br />Utilities Jetting & CCTVRFP #PWD-25.602 <br />Docusign Envelope ID: 6DEA63F0-E323-49F7-80B4-CF3B1B9C8EF1
