Vice President Enclosure: Fee Proposal CC; Mark Blanchard - M&E Jay Ameno - M&E Jim Penkosky - M&E TASK ORDER ~01-03 March 27, 2001 FEE PROPOSAL AND SCOPE OF SERVICES CITY OF BOYNTON BEACtl INFILTRATION/INFI.~W Rk~BUCTION - PHASE IA PRELIMINARY SANITARY SEWER COLLF~CTION SYSTEM SURVEY Background It is the intent of this scope of services to provide engineering support services associated with implementation of an inf'fltration/inflow (I/I) reduction program for a portion of Boynton Beach's sanitary collection system. The portion of the system under program consideration is defined by the following areas: a) north of C16 Canal, b) east of 1-95, c) south of Hypoluxo Boulevard, and d) west of the Intercoastal waterway. This area's wastewater collection basins are eventually transferred to master lift station 309. This lift station's storm induced excessive runtime hat identified the program area as one in which Ill should be reduced. The area consists of 20 primp stations, approximately 27 miles of pipe, and 550 manholes. The City desires to reduce Ill as part of an overall mission to properly maintain the utility infrastructure and pursue a proactive and cost-effective expenditure of resources. The following was provided by the City to M&E to facilitate this proposal: a map showing the general layout of the study area, and recent pump station runtimes and capacities. Metcalf & Eddy recommends that the City follow other successful ldI reduction program approaches. These programs use a three-phase approach to identify sanitary sewer system deficiencies. The ultimate goal of the three-phase approach is the physical rehabilitation of the sewer system to reduce ldI. We propose a four-phase approach (modifying the f'n'st phase). These phases are summarized briefly below. Phase IA - Preliminary Evaluation Report. The objective of ~his phase is to prioritize the collection basins on the .basis of Ill severity, so that ~e subsequent engineering and construction activities can be properly focused. Sub-tasks consist of delineation of the system based on sewer service areas and sewer subsystems, inventory of pump station and collection system infrastructure characteristics, and an engineering analysis of FI for the sewer system. Usually up to one year of data is considered. Limited inflow data c-in be collected during this phase. Phase IB - Preliminary Sewer System Survey. The objective of this phase is to conduct comprehensive field data measurements such as flow monitoring (necessary for accurate inflow measurements), salinity monitoring, and dye and/or smoke testing. A further engineering analysis of FI for th~ sewer system is conducted based on the data collected. Phase Il _ Sewer System Analysis. The objective of this phase is to formulate a rehabili*ation plan for implementation in the construction phase. Sub-tasks consist of inspection and quantification of ..Sl~C.. ifie FI sources, modified cost-effectiveness analysis for repairs and rehabilitation techniques, specification of sewer rehabilitation methods, and Creation of an hnplementation plan and timetable. Phase I11 - Rehabilitation. The objective of this phase is to implement the rehabilitation plan specified in the previous phase. Sub-tasks consist of construction oversight for compliance with the rehabilitati verification through post-repair flow measurement [..hat enginee~ been met. Ideally, the program can be arranged so that the significant defects is completed promptly after identification o: thereby achieving immediate benefits in FI reduction. That is, th phase should be considered as an ongoing effort, and run coJ previously described evaluation and inspection phases. ~n plan~ arid g criteria have ~habilitation of such defects, rehabilitation :urrent to the This proposal is intended to provide engineering services to support Phase IA of the overall ldI reduction program. SCOPE OF SERVICES 1.0 2.0 Project Management I. 1 Management Project Management activities comprise contract administration, coordination of project staff, monitoring of progress and project costs. 1.2 Owner Liaison M&E will attend up to three meetings with representatives of the City durkng the project as follows: a. Preliminary review meeting, b. Progress review meetings, and a c. Final review meeting. Preliminary Sewer System Survey 2.1 Data Collection and Field Investigation M&E will perform the following activities for the study referenced herein: 1. Perform a comparative analysis of metered wastewater flows in relation to the following sources of data over a one-year period (where available): a. Metered water usage for 1_3309 service area vs. wastewater flows discharged from LS309 from meter reading routes b. Rainfall vs. pump station runtime (for inflow estimates) c. Groundwater table elevation d. Tidal elevation (for coastal areas only) 2. Develop basin and sub-basin schematics based on the Boynton Beach sewer atlas 3. Compile the following data for each basin in the program area: a. Pump station - number, capacity, and average operating time b. Collection system - pipe diameter, lineal footage, pipe material, and number of manh61es c. Surcharge condition (if associated with rain) 4~ 4 d. History of overflow and/or odor complaints (if associated with rain) e. Key manhole identification f. Night flow estimations (I:00 AM to 5:00 AM) for all pump stations (for fzll rate and pumping drawdown) Analyze and prioritize collection basins for I/I severity to focus subsequent design and construction activities Identify and eliminate non-problem areas from the study area Document findings for use in Phase 13 and II engineering analysis Provide Rough-Order-Magnitude cost savings estimate for possible flow reductions M&E will work cIosely with City personnel throughout data collection and analysis. It is anticipated that City personnel will be available on a limited basis to assist M&E with our efforts. 2.2 Preliminary Evaluation Report M&E will prepare a preliminary evaluation report ('PER) which will consist of the following elements: a. Dam Collection Summary b. Immediate Term Sewer Repair Evaluation Schedule (from observed leaks found during system evaluation in 2.1.3) c. Outline of Work for Phase 13 Upon incorporation of comments from the PER review meeting, a final evaluation report will be issued. This report will be used as the basis for subsequent work. The Phase I report will be further developed in Phase IR and II analyses. M&E will adhere to the following process for the Phase IB report: at an early phase of task execution, meet with City to agree on an outline format for the report; upon substantial completion of the task, submit to the City for review up to three copies of a draft; and, after City review of the draft and consensus regard:ling revisions, submit to City up to five copies of the f'mal document. 4 3.0 1.

Metered water usage for the study period will be obtained from the City water use and/or billing records. 3. aster lift Station 309. at the City's ml~ainfall for the study period will be obtained using data collected 4. Groundwater table elevation for a one-year period will be obtained from existing United States Geological Survey groundwater monitoring wells. 5. Tidal elevation (for coastal areas only) for a one-year period will be obtained from available National Oceanic and Atmospheric Administration records. 6. Basin and sub-basin boundaries, and sewer system layout andI infrastructure description (pipe diameter, linear footage, pipe material, arid number of manholes), will obtained from the existing City sewer atlas. 7. Pump station number,, capacity, and average operating time will be obtained from City records. 8. Collection system surcharge condition, and history of overflow and/or odor complaints, wilt be obtained from City records.
