SMITH AND ASSOCIATES, INC, hereinafter referred to as "Engineer" pursuant to the mutual promises, covenant and conditions contained in the Master Agreement (Category 2E) between the above mentioned parties dated October 22, 2013. The Project Name for this Task Order 10425.a is as follows: CITY OF MERIDIAN FALL 2014 - INFILTRATION AND INFLOW MONITORING AND ENGINEERING SERVICES PROJECT UNDERSTANDING Between 2009 and 2011, MSA supported the City in collecting multiple phases of collection system flow monitoring data. These phases of testing were focused on identifying sources of infiltration and inflow (1/1) throughout the City. At the conclusion of the 2011 phase of monitoring, MSA recommended a long-term monitoring program. In 2012 and 2013, MSA supported the City in the first and second year of the long-term monitoring program. The 2012 and 2013 effort also included review of the SCADA analysis of Black Cat South and Ashford Greens lift stations to quantify 1/1 responses in Black Cat sub basin. The 2013 study included three flow meters near the Wastewater Treatment Plant (WWTP) to meter the influent lines. The City has eight (8) meters available for flow monitoring. This scope of work (SOW) will collect and analyze data from these meters in support of the long-term monitoring program. The 2014 monitoring is the third and last year of the first phase of the recommended long-term monitoring locations. The long-term monitoring program is also transitioning to the Strategic 1/1 Monitoring Plan. The following tasks are included in this scope of work: 1. Install and Maintain Flow Meters a. Strategic Monitoring Plan: Long -Term Locations b. WWTP Influent Lines 2. Analyze Lift Station SCADA Data 3. Analyze Flow Meter Data and Generate Strategic 1/1 Monitoring Program Report Task Order 10425.a FALL 2014 - Infiltration And Inflow Monitoring And Engineering Services Page 1 of 4 MURRAY, SMITH AND ASSOCIATES, INC SCOPE OF WORK Task 1 — Install and Maintain Long -Term Location Flow Meters Under a previous task, MSA supported the City staff in the installation of the flow meters, in late August of 2014. MSA identified the following three (3) locations in the system as part of the long-term monitoring effort. • L8-21 • L10-27 • M12-179 MSA identified the following five (5) locations for placing flow monitors in the collection system to focus the metering on basins of concern based on the conclusions of the previous study. • Downtown o M12-265 o N1 2-07 • Black Cat South o N8-87 o N8-249 o P10-04 MSA will monitor all locations on a bi-weekly basis, downloading the data and changing batteries when needed through December. Any issues requiring confined space entry into the manholes will be coordinated and conducted by City staff. MSA will also coordinate the acquisition of rainfall data with City staff during the monitoring period. Deliverables: No specific deliverables will be provided as part of this task. Data analysis will be summarized in Task 3. Task 2 — Analyze Lift Station SCADA Data MSA will analyze lift station SCADA data for the Black Cat South and Ashford Greens lift stations focusing on the specific identification of 1/1 in the system. This analysis will continue to help the City understand 1/1 in this part of the system. Deliverables: No specific deliverables will be provided as part of this task. Data analysis will be summarized in Task 3. Task 3 — Analyze Flow Meter Data and Generate Strategic 1/1 Monitoring Program Report MSA will develop a Strategic 1/1 Monitoring Program Report based around the EPA Guide for Capacity, Management, Operation & Maintenance (CMOM) Programs, and Sanitary Sewer Collection Systems. The report will be formatted as a document that can be used and updated annually as conclusions and recommendations for the monitoring change with additional information. The document will include the following: Task Order 10425.a FALL 2014 - Infiltration And Inflow Monitoring And Engineering Services Page 2 of 4 MURRAY, SMITH AND ASSOCIATES, INC Summary of the City historical 1/1 monitoring and reporting (e.g. past report conclusions, monitoring methods and practices). • Documentation of monitoring methods in detail. This may include manhole location [GPS/photos/water features nearby], flow meter specifications/model information, name of personnel collecting meter data, time/date data was collected, and weather on collection days. Documentation of the strategic monitoring plan. Likely spread over 5 or more years and focused on areas of highest 1/1. Summary of the findings for the discrete areas monitored and comparison of the results to monitoring results from previous phases. Executable recommendations (e.g. install permanent flow meter at location "X", smoke testing at future date, increase maintenance spending, potentially focus available funds on WWTP capacity because of the challenges in controlling 1/1 within the collection system, purchase a new weather station and install at location "X"). Other aspects of future phases of the Strategic Monitoring Plan could include: ► Monitoring during wet and dry seasons • Creating of 1/1 calibration data for the sewer capacity model • Monitoring after significant repairs to the collection system are completed A meeting to discuss the results and recommendations from the monitoring with the City is included in this task. Deliverables: A draft and final report will be generated as part of this task and delivered to the City. ASSUMPTIONS Task 1 Assumptions: ► Five (5) hours of time has been assumed for every two (2) weeks of a three (3) month duration for the maintenance and downloading of the data. Meter Maintenance Fee of $35/trip will be charged for field data collection and maintenance efforts for installation, biweekly field check and removal of flow meters. a City will provide rainfall, lift station, and wastewater treatment plant data as requested. Task 2 Assumptions: ► City will provide SCADA data for the Black Cat South and Ashford Greens lift stations flows (and/or wetwell level) in 15 -minute time steps for the period between beginning of September and end of December. Task 3 Assumptions: • City will provide comments on the draft report for incorporation in the final. • One (1) meeting will be conducted with the City to review results and discuss next steps.
