The city has outlined several tasks associated with this project. They are as follows:
Task 1. Design, estimate, and project outline for
treatment system:
- Determine design specifications based on site conditions and groundwater chemistry
- Determine necessary equipment
- Project timeline
- Project/construction cost estimate
- Produce monthly reports and final report (final report required within one month of
completion of this task)
The City and contractor will then evaluate results of Task 1. If Task 1 is
successful, work will continue on to Task 2.
Task 2. Construct a pilot-scale treatment system:
- Determine necessary components and size them to treat the flows from well 14.
- Purchase and construct the pilot-scale treatment system.
- Produce monthly reports and final report (final report required within one month of
completion of this task)
Task 3. Determine if treatment system will meet City's
objective for VOC treatment:
- Develop a report detailing costs, operating requirements, and all engineering for sizing
the system and determine if the system meets the City's objectives of safety, cost
effectiveness, and treatment successfulness. This report is required within one month of
completion of this task.
- Revised project/construction cost estimate
The City will then evaluate results of Task 3. If Task 3 is successful, work will
continue on to Task 4.
Task 4. Determine full-scale sizing:
- Develop a report outlining all the sizing requirements and specifications necessary to
scale up the treatment system to a full-size system within one month of completion of this
task. A full-size system is a system that will treat up to 2,000 gallons per minute for
removal of ninety-five percent (95%) all volatile organic chemicals (VOC’s).
- Estimate capital costs, operation and maintenance costs and equipment necessary to build
and maintain a mobile full-scale system that could be used on any of the city’s
wells.
