About this file
This document is Attachment H from the Orange County Utilities Department, providing detailed maintenance recommendations for Private Pump Stations (PPS) and Private Collection Systems (PCS). The attachment includes a comprehensive maintenance recommendations checklist that outlines specific monthly, quarterly, semi-annual, and annual maintenance tasks for utility infrastructure. Key maintenance activities include securing the pump station during visits, maintaining audible and visual alarm systems, inspecting pumps and electrical components, verifying pump operations, recording motor run times, and performing thorough cleaning of wet wells and sewer lines.
The maintenance checklist provides granular guidance for utility maintenance personnel, with tasks ranging from securing facility keys and locks to inspecting electrical connections, checking float devices, and ensuring proper pump cycling. The document notes that maintenance frequency may vary depending on the specific operating conditions of each pump station, with more frequent inspections recommended for facilities receiving higher quantities of waste or experiencing more challenging operating environments. The recommendations are designed to reduce system failures and associated repair costs by establishing a structured, proactive maintenance approach for critical utility infrastructure.
