About this file
This file contains architectural and engineering drawings for the Eleventh Addition to the Nine Springs Wastewater Treatment Plant for the Madison Metropolitan Sewerage District in Madison, Wisconsin. The drawings detail the construction specifications for two acid digesters (numbered 1 and 2) and associated facilities including a recirculation pump room, transfer pump room, and sour gas room. The project drawings, dated October 2011, include detailed elevations, sections, floor plans, mechanical systems, and electrical layouts for the digester facility.
The drawings provide comprehensive technical specifications for the construction, showing the digesters as circular structures with dome covers, access platforms, sidewall hatches, and mixer shafts. The facility includes brick veneer exterior walls, insulation systems, and specialized piping for acid handling. The mechanical drawings detail extensive piping systems for both digesters, including sour gas handling equipment and pump systems. The electrical plans show Class 1, Division 1 hazardous area classifications and associated lighting and power requirements. The project is identified as Project No. 4635 and includes requirements for specialized construction methods for handling acidic materials and hazardous environments.
