This study will assist the City in determining system transmission and wastewater treatment capacity needed through buildout. The City has an existing contractual capacity limit of 7.04 MGD measured as the three continuous maximum monthly average for wastewater treatment with Broward County. The average monthly wastewater flow from the City over the last two years has increased from 6.6 MGD in 1996. There have been several months recently in which the monthly average flows have been over the contractual limits and penalty surcharges have been assessed. With the projected development within the City, there is no question that additional wastewater treatment capacity will need to be secured. The City staff has met with officials of the Broward County Wastewater Management Division to discuss wastewater treatment and conveyance capacity issues. They explained the current plans of the County to expand the plant capacity issues. The County is planning plant expansion. The expansion will most likely be a combination of process modification and effluent disposal through injection wells. This may increase the treatment plant's rated capacity from 80 to 86 MGD. The second phase of the expansion may be an additional process train that may increase the rated capacity of the plant to 100 MGD. Presently, there are no firm schedules for the expansion plans. It is anticipated that the project will be completed in mid -calendar year 1998. The implementation of process modification and the effluent wells could take about 18 months to complete, and the design and construction of an additional process train could take between 3 and 4 years. Therefore, the City is at least 18 months, and probably closer to 4 or S years, before having additional capacity available from the treatment plant. This project involves the preparation of a capacity analysis for the City's wastewater transmission system. A major component of such an analysis will be a projection of the future wastewater flows for Tamarac. Based on the purpose of this Wastewater Transmission Capacity Analysis for the City of Tamarac, the study is described below. r--I TASK 1 - DATA COLLECTION Data will be collected from, but not be limited to, the offices of the South Florida Water Management District (SFWMD), Florida Department of Environmental Protection (FDEP), City of Tamarac Community Development Department, Broward County Planning Department, the Soil Conservation Service, the United States Geological Service, Department of Community Affairs, and others. The data collected will include, but not be limited to, Agreement with Broward County, FDEP Monthly Operating Reports, drawings and engineering reports (if available), soil data, land use maps, building permit data, planning department reviews and other relevant information. Such data will be utilized in assessing the City's inflow and infiltration problems. TASK 2 -INTERIM CAPACITY MEASURES Interim treatment capacity must be addressed in order to serve existing projects and those that are projected for the next few years. The most viable alternatives that Hartman & Associates, Inc. will address include: A. Purchase capacity from another large wastewater user. It appears that Pompano Beach has additional capacity. They currently have 3 MGD surplus based on the average of their last 12 months. Even with considerations of future growth, they may be able to release up to 2 MGD. In order to secure all or a portion of this capacity, the County believes that Tamarac would need to compensate Pompano Beach for its costs. The City will take the lead in contracting municipalities to ascertain availability of options. Once the City determines which municipality to work with, HAI may assess the associated costs. B. "Borrow" some capacity from other large users. There are a few large users, including Coconut Creek, that, although they will eventually need their assigned capacity, the timing of their wastewater needs may be such that they could "lease" some capacity to Tamarac until the Broward treatment plant expansion is completed. C. Increase I&I reduction efforts. Although a reduction in infiltration and inflow (I&I) does not directly secure additional capacity, it reduces the average of the flows from the existing system to free up capacity for new growth. An evaluation of the cost/benefit will be reviewed. D. Allow for months of exceeded flows reimbursing the County as required until such time as the plant is expanded and additional capacity is available to large users. HAI will discuss a rate to recover the interim surcharge costs and future capacity costs for the City. Under separate assignment, a detailed cost allocation could be performed. E. Divert more wastewater flow to the City of Ft. Lauderdale. HAI will investigate the feasibility of this future option. Potentially, the City of Ft. Lauderdale could serve the incremental needs of the City and this cost will be compared to the County cost. GCH/chs/96-108.08/corresp/ Rabbat.att -2- 042998 • F. Water conservation analyses and programs to reduce wastewater generated. HAI will assess the effectiveness and make recommendations regarding this component. G. Rate and charge pricing analyses such that increased costs are incurred with increased uses. TASK 3 - EXISTING WASTEWATER SYSTEM A. Wastewater Transmission 012timization HAI will evaluate the existing wastewater pumping stations to delineate the hydraulic range of performance and design conditions to allow for the bypassing of the existing repumping station and possible retirement of the same. All piping, equipment, rerouting and other improvements will be described with an associated detailed cost estimate. The improvements costs and operational costs will be compared to the repumping costs and refurbishment costs to ascertain the most cost-effective, reliable and efficient system to implement. Existing studies of the wastewater system will be provided by the City's staff. An engineering opinion overview will be performed on the wastewater transmission system. It will be necessary to obtain from the City of Tamarac information on all pump stations and transmission mains. This information will include: 1. pump make and model or head curves; 2. wet well diameter; 3. wet well depth; 4. invert depth; 5. float switch or bubbler level settings; 6. overall wastewater transmission system map; 7. transmission main lengths and diameter; 8. Cybernet data files and key maps. The overview will be directed at determining system deficiencies and recommending improvements to the wastewater transmission system including pump station maintenance, repair and replacement. The affect of inflow and infiltration on the sizing of such transmission facilities will also be discussed. Discussion text and detailed transmission system maps will be provided to summarize the review. TASK 4 - REGULATORY REVIEW Deleted. GCH/chs/96-108.08/corresp/ Rabbat.att -3- 042998 TASK 5 - POPULATION CUSTOMER AND FLOW PROJECTIONS Based on a review of the historical population and growth projections as developed in the City's and County's Comprehensive Land Use Plans, building permits, traffic zone data and other relevant information, an accurate forecast of population and ERC's through a 15-year forecast horizon will be developed. Projections will be coordinated with the City Planning Department. Flows will be categorized as prior committed flows, near term development flows, fill-in flows, long term development flows and future projected flows. Such projections will predict future system deficiencies and illustrate seasonal operational trends. These characterizations will aid the development of the conceptual ERC and CIAO fee evaluation, and the implementation of I/I programs. Historical peak flow information will be reviewed to determine the appropriate peaking factor. TASK 6 - WASTEWATER TRANSMISSION SYSTEM EVALUATION A. Wastewater Transmission System Analysis Based on the information obtained from the City of Tamarac relative to the wastewater transmission facilities, HAI will utilize the existing a pipe and node map of the wastewater force main system, as well as the City Cyber-Net data file based upon the node map for input into the computer run. The program will be utilized to model selected areas of the wastewater force main system under various forcemain pressures. Based upon the data from the previous sections of the report, HAI will develop a per ERC wastewater generation for projection of future wastewater needs. HAI will coordinate with the City's Community Development Department and focus on 5 lift stations that will be impacted by new development (ERCs). One of these areas will be land section 7. An estimate of the future wastewater generation per pump station service area, based upon total build -out development units and per ERC, will be developed. HAI will develop four scenarios to include: 1. Existing System. 2. Future System Improvements (5 years). 3. Future System Improvements (10 years). 4. Future System Improvements (15 years). TASK 7 - INFLOW/INFILTRATION EVALUATION A preliminary study will consist of collecting and reviewing all available engineering data pertaining to the wastewater collection and transmission system. The review of the system will include collecting and summarizing the following information. 1. Raw wastewater quality; 2. Water demand by wastewater catchment area and wastewater flow data (pump run times); 3. Daily rainfall data (from gauge at WTP); GCH/chs/96-108.08/corresp/ Rabbat.att -4- 042998 4. Wastewater collection system drawings and reports; 5. Customer data; and 6. Interviews with key staff. Following the collection of preliminary data, HAI will perform a cursory analysis to quantify the overall contributions to the Broward County WWTP. HAI will also identify I/I contributions by sub -area and prioritize each sub -area based on estimated I/I contributions. This study will also recommend and prioritize a course of action to reduce the I/I in the system. TASK 8- WASTEWATER SYSTEM PLANNING (CIP) Deleted. TASK 9 - ECONOMIC ANALYSIS Based on the existing and near term capital improvements for the City's wastewater system, and the improvements recommended to reduce I/I in the City's collection system, cost of capacity purchases, and the cost of surcharges on present flow generation, an economic analysis will be conducted on all viable alternatives developed. Utilizing the customer projections, capital costs, staffing and operational requirements, is and other relevant data determined in the previous tasks, a range will be developed that will identify the average costs per customer. • TASK 10 - DRAFT AND FINAL REPORT Ten (10) copies of all preliminary draft report will be provided to the City staff for their review. A review meeting will be conducted to review the draft report and discuss any comments the City may have. As a result of the review meeting, the City's comments will be incorporated into the final report and twenty (20) copies of the final report will be submitted for approval. In addition, HAI will present the final report to the City Commission. TASK 11 - WASTEWATER SYSTEM ATLAS MAPS Deleted. TASK 12 - WORKSHOP PRESENTATION If requested, HAI will present our findings to the City Commission in a workshop format to provide ample time for questions and discussions of the projects.
