9. Analyze dewatering performance including solids capture, polymer consumption,
and cake solids. Summarize annual average, peak monthly, and peak daily sludge
quantities.
10. For WWFTF flows, summarize available data on BOD and TSS removal rates and
effluent quality in terms of concentration and loading.
E. Conduct Plant Infrastructure Assessment
1. Develop a comprehensive plant infrastructure asset inventory:
6.
Prepare technical memorandum summarizing projected growth in residential,
commercial, industrial, and institutional flows. Meet with City staff to review and
finalize memorandum.
D. Analyze WWTF Effluent Quality and Sludge Quantities
12/10/19
1,
Analyze primary treatment removal rates for BOD and TSS and typical effluent
quality both in terms of concentration and mass loading. Summarize available data
on primary sludge quantities and compare to predicted values based on removal
rates.
B. Project Administration and Meetings
1. Each month we will submit a report that details the work performed by the team
on each major task with the monthly project invoice.
2. The following meetings will occur throughout the duration of the project:
a. Eight (8) progress and brainstorming meetings with the project team and
City staff.
b. One project presentation meeting to present final report to City staff.
C. Define Current and Projected Future Influent Wastewater Flows and Loads
12/10/19
include reports for the WWFTF. It is assumed the other CSO facilities
are not part of this facility planning effort.
The current and draft NPDES permits, the status of discharge
requirements at the facility, and the pending application for a new permit.
The latest budget and Capital Improvements Plan (CIP). It is assumed the
City will provide:
