Dear Sir:
Contract documents and specifications have been prepared for Contract 15-122-3P Aeration Tanks Air Valves Automation in Batteries A, B, C and D, Stickney Water Reclamation Plant (WRP).
The purpose of this project is to replace existing manually operated angle globe valves with new automated valves. The first half of Pass 1 of each aeration tank in Batteries A, B, C and D has been converted to an anaerobic zone, as part of the process modification for enhanced biological phosphorus removal that is being implemented at Stickney WRP. This valve replacement work will facilitate an easier and safer means of operating these valves. The associated process air piping will also be modified.
The project consists of the following:
1. Remove and dispose of one hundred and twelve (112) existing 4” angle globe valves and drop air pipes in Aeration Battery A and Battery B each.
