Wylie WTP I Washwater Supply Tank Improvements

The Project includes construction of the following: 1. A new 0.5 MG Washwater Elevated Storage Tank (EST). 2. Demolition of the existing washwater storage tank. 3. Approximately 350-LF of 24-inch fill piping from the washwater supply pumps to the EST and approximately 350-LF of 30-inch drain piping from the EST and terminating at an existing 30-inch backwash influent pipe near the existing washwater storage tank. Both the fill and drain piping includes approximately 90-LF of pipe to be installed By Other Than Open Cut (BOTOC). 4. A new 3400-4100 GPM washwater supply pump to be installed at HSPS 1-1 with discharge piping connected to two existing washwater supply pumps. 5. Yard piping improvements to tie-in the 30-inch drain line to the existing backwash influent pipe and modifications to existing washwater supply pump discharge piping. 6. A new calcium thiosulfate chemical feed system that includes a bulk storage and containment facility, transfer pumps, transfer piping and chemical trenches, day tank and containment, chemical feed pumps and mixing/carrier water pumps. 7. Electrical and instrumentation related to new equipment and other improvements in this project. 8. New paved access road to connect the chemical bulk storage facility to existing plant road, miscellaneous existing paving improvements and general site civil and drainage.
