CCJM prepared a study report to provide a rehabilitation concept for the Liquid Oxygen (LOX) Plants and develop a planning level of the Engineer’s opinion of probable LOX Plants’ rehabilitation construction cost.
Patapsco Wastewater Treatment Plant (WWTP) Secondary Clarifiers and Gravity Sludge Thickeners Rehabilitation
CCJM prepared a study report to provide rehabilitation needs for the eight (8) Secondary Clarifiers and three (3) Gravity Sludge Thickeners (GSTs) at the Patapsco WWTP and developed a planning level of the Engineer’s opinion of probable construction costs.
Task No. 5 WC #1395 – Montebello Water Filtration Plant II Dehumidification System Improvements
Since 2010, the dehumidification system at the Montebello Water Filtration Plant (WFP) II has been disabled. CCJM is currently preparing Contract Documents for renovation of the dehumidification system at the Montebello WFP II to eliminate further damage to the piping and equipment and to correct the unsafe environmental concerns.
Task No.6 SC #986 – Improvements to the Deep Manhole and Primary Settling Tank Drainage System at the Back River Wastewater Treatment Plant
The main function of this DMS is to collect drainages from the PSTs and other processes, and then convey the flows to the Dewatering Stations. The DMS is an essential component for the functioning of the PSTs and the wastewater treatment processes. CCJM is currently preparing a study report to provide the rehabilitation and/or replacement necessary to improve the Deep Manhole and Primary Settling Tank Drainage System.
Project Cost: $1,000,000
