20-Final Draft Schedule B-10 JIWRF and SSWRF Basin Cleaning List.xlsx

The document is an Excel spreadsheet (Schedule B-10) detailing cleaning frequencies for wet wells and basins at two water reclamation facilities: the Jones Island Water Reclamation Facility (JIWRF) and the South Shore Water Reclamation Facility (SSWRF) for the Milwaukee Metropolitan Sewerage District. The spreadsheet comprehensively lists over 200 specific infrastructure components, including influent channels, grit basins, primary and secondary clarifiers, aeration basins, wet wells, contact basins, and various other water treatment infrastructure elements. Each facility component is assigned a facility number and a cleaning frequency, which is either annually (AN) or biannually (2Y).

The cleaning schedule is part of a broader Operation and Maintenance contract for water reclamation infrastructure in Wisconsin, solicited through a Request for Proposals (RFP) by the Milwaukee Metropolitan Sewerage District. The document suggests a systematic approach to maintaining critical wastewater treatment infrastructure, with specific attention to regular cleaning of various treatment process components. The cleaning frequencies indicate a proactive maintenance strategy designed to ensure optimal performance and longevity of the water reclamation facilities' critical infrastructure.
