Background The United States Environmental Protection Agency (EPA) cited the City of Hollywood for failing to meet the wastewater treatment plant NPDES permit conditions and issued Administrative Order No. 90-083 requiring that a regional infiltration/inflow (Ul) flow reduction program be implemented within a stipulated time frame. The City of Hollywood as the lead agency for the Broward County Southern Wastewater Region advertised for professional services to undertake an VI study for the entire regional collection system. The VI study consisted of two phases or work: an VI Analysis followed by a Sewer System Evaluation Survey (SSES) program. The City of Hollywood and representatives from each Large User selected and retained Hazen and Sawyer, P.C. to perform j these professional services in June 1991. In July 1991 the City of Hollywood submitted to EPA ( a report entitled, 'Preliminary Infihration/Inflow, Analysis of the Regional Collection System' prepared by Hazen and Sawyer. In August 1991, Hazen and Sawyer was authorized to commence the Infiltratlon/ Inflow Analysis for the Broward County Southern Region Wastewater Collection System. Field and office services were provided from August through January 1992. The final VI Analysis report was forwarded to EPA in January 1992. The report Identified a potential 4,320,000 gallons per day of dry and wet weather Vi flow reduction which could be Implemented at a total cost of $10,700,000. The SSES phase of work Is now required to determine the location of site specific sewer defects. Funding sources to implement the project are as follows. Phase of Work Total Cost Funding Sources 1/1 Analysis $ 500,000 1991 Hollywood Water and Sewer Revenue Bond Issue SSES Program 1,500,000 1991 Hollywood Water and Sewer Revenue Bond Issue Rehabiiitaflon Program 8,700,000 Future Sewer Bond Issue or financed separately by Large Users $10.700,000 c In December 1991 the City of Hollywood,as the lead agency entered Into a settlement agreement with Broward County ONRP to rescind an areawlde sewer moratorium. As part of the settlement agreement the City committed to reduce the VI flows by 1,000,000 gallons/day over an initial 12 month period and provide an additional 1,500,000 gallons/day reduction over the next 12 months. The Broward County Southern Wastewater Region Is obliged to implement a regional VI flow reduction program to meet the following commitments. • EPA Administrative Order • Broward County ONRP settlement agreement I - I Hwd:3542P A•2 - . .. i 04.09.92 i j I . l I In January .--__-,eoruar/ 1992 meetirgs Nere meld separately and ,achy N14.,�,;c'Large :aer;. The program scope of lvom. implementation schedule and estimated cost were reviewed vvdh each Large User. Hollywood, as the lead agency will be responsible to manage and implement the regional lil how reduction program. Those Large Users which elect to undertake the VI flow reduction program within their individual service areas will be responsible to meet EPA F requirements / documentation as well as the regional project schedule. The next two steps required to implement the Inflow/Infiltration program are as follows: r f SSES Program Undertake a Sewer System Evaluation Survey(SSES)to physically Identify specific defects 1111 in each drainage area with excessive VI flow and outline a cost-effective rehabilitation l program to correct the sewer system defects. Rehabilitation Program j j' Direct specialty contractors to undertake the specified sewer repairs to eliminate system defects and reduce VI flow contribution. In order to meet the terms of the EPA Administrative Order and the Broward County ONRP time schedule as outlined In the settlement agreement, both the SSES and Rehabilitation programs must commence concurrently. It is anticipated that the full VI Reduction program should be complete within 2 1/2 years. The City of Hollywood has committed to this schedule. Hazen and Sawyer will be the program administrator directing and coordinating both the SSES and Rehabilitation Programs. For those Large Users who decide to undertake all or part of the SSES%Rehab work with their own forces, Hazen and Sawyer will be responsible to review and document their progress and results in reports to EPA and Broward County ONRP. Hazen and Sawyer PII t p monthly with the City of Hollywood and the representatives of the Large Users to review prof progress and Identify potential problems. Hazen and Sawyer, as program administrators for the SSES and Rehabilitation Programs,will act as agents of the City of Hollywood,the lead agency of the Broward County Southern Wastewater Region.

Infiltration will then be measured at micro-system key manholes by taking 'instantaneous'flow measurements during the early morning hours. These measurements will be correlated with continuous flow monitoring results. -Instantaneous' flow measurements will be obtained using hand weirs as follows: Flow isolation will consist of isolating a designated reach of sewer during the early morning hours (midnight to 6:00 a.m.) by measuring in the sewer as necessary to determine infiltration rates. Where practical, weirs will be used to measure the flows. Where the usage of weirs is not practical, the flow will be measured by dipstick and velocity measurements. • For each location where flow isolation is performed, a now isolation report will be completed. Then, a determination of whether further flow Isolation or TV inspection work Is required to locate Inflltratlon sources will be made. If required, Instantaneous How isolation may be accomplished on a segmental basis (manhole to manhole).

The ENGINEER will meet monthly with the City and Large Users to review the program status and discuss potential problem areas. Under this task the ENGINEER will be responsible to compile all cost associated with the SSES and rehab programs and allocate these cost equitably between the City and Large Users in proportion to the actual services provided. These cost and the back-up data will be compiled and made available for outside audit. Task D.7 Documentation of Work Performed by Others Some Large Users may elect to perform some of the recommended repairs with utility sources or their own contractors. The ENGINEER will review the documentation provided by these Large Users to be used In a report to EPA and BCONRP. The ENGINEER will review the program requirements with each nonparticipating Large User, obtain the field data, compile it in a format consistent with the program, review and evaluate the findings and detail the field work for final report Where additional data Is needed, such as flow measurements. the ENGINEER will notify the nonparticipating Large User of the minimum data needed. The nonparticipating Large Users must provide engineering certification that the repair work was performed in an acceptable manner. Task D.8 Final Report A final report documenting the SSES and rehabilitation work results will be prepared by the ENGINEER. The report will list the SSES findings by drainage area.the rehabilitaton work performed and the before and after flow measurements to document the actual I/I reduction attained. The report will then combine the results from each drainage area and determine overall regional VI flow reductions. The report will be Issued to EPA and the BCONRP to complete the requirements of the Administrative Order and the Settlement Agreement. i E. Additional Services The City and individual Large Users may request additional services during the SSES and Rehabilitation Programs with respect to the sewer systems The Engineers will be in the field gathering as-built data and conducting flow measurements. It may be cost effective i for the respective Large Users to update their sewer maps and obtain field data for O&M software programs. The respective Large Users will be charged for these services and these additional costs will be allocated to each Large Users account. A typical service available to Large Users is electronically digitizing sewer maps on the L Auto CADD or other GIS system. The data base can be constructed from the following systems: • Construction and as-built documents of sewer systems (furnished by Large Users) Hwd:9542P A-22 04.09.92 tea. t4xy..� , , % sti j, . . - . . •. 3''�,�s'2' a I• '- 1 i ?rc&ard Ccur,rj :'etropcistan Area Atlas 'Redi' maps Geographic Information System (GIS) map of Southern Broward County • Existing CADD street maps The Engineers can locate manholes and sewer lines into the base maps by digitizing this information from existing sewer maps. During the detailed manhole inspection phase of the SSES and. in those areas where CADD mapping is requested by the large Users, locations of manholes and sewer lines will be confirmed and updated. Field crews will measure the collection line length between manholes using a rollatape and, will locate the manholes within easements, streets and intersections by measuring the distances to curb and/or property lines. On those sewer lines that will be televised during the SSES, location of the service lateral connections to the main will be verified. Field investigation information will be Incorporated into the CADD map files. The Engineers will provide mapping overlay on the pre-prepared base sheets at any desired scale (usually 1' - 600' or 1' . 200 scale). The completed mylar sectional maps will be delivered to the Large User along with the electronically stored CADD files at the end of this activity for their use. Other services the engineers can provide during the program are as follows: i • Additional flow measurements Field surveys i update sewer O&M software files with as-built Information • Design sewer rehabilitation projects (beyond VI repairs) l • Conduct studies or designers on private sewer lines or laterals • Update sewer ordinances The Large User will outline a Scope of Work for a specific work order. The Engineer will prepare a proposal with a not•to-exceed cost If both parties agree with the Scope of Work and engineers cost to perform these services, then the Large User can authorize the Engineer to proceed if adequate unallocated funding is avallabie under this agreement and the City of Hollywood approves the use of these funds. If adequate unallocated funds are Is not available, then an amendment to this agreement must be Issued and approved by i the Hollywood City Commission prior to authorizing work to proceed. j -� HNd:3542P A-23 .. 04-09-92 i "e i F.

Palm Utilities Director f CITY OF DANIA j 100 West Dania Beach Boulevard Dania, Florida 33004 Professional Engineering Services During the City of Dania Wastewater Collection System Rehabilitation Dear Mr. Palm: 1' In order to establish the background, context and frame of reference for Hazen and Sawyer's Invoice dated September 30, 1993, (copy attached), the following statements and explanations are given: 1. On September 28, 1990, the City of Dania, (hereinafter referred to as the "CITY'), and the City of Hollywood, Florida ("Hollywood")entered into a Large User Wastewater Agreement y (h6reinafter "Large User Agreement"). According to the Large User Agreement the City is defined as a "Large User". 2. On April 26, 1991, Hollywood, on behalf of the Large Users, advertised for consultants to render professional engineering services to provide an infiltration and inflow study ("UP), a sewer system evaluation survey study ("SSES), and rehabilitation engineering which would encompass the entire wastewater collection service area, which includes the CITY's sanitary sewer system. ' 3. On May 29. 1991, a selection committee comprised of Large User representatives, including CITY, reviewed the consultants qualifications and shortlisted two firms. On June 5, 1991, after presentations were made the selection committee recommended the 1/1, the iSSES, and rehabilitation engineering work be awarded to Hazen and Sawyer, P.C. fi (hereinafter referred to as "ENGINEER)in accordance with the Consultant's Competitive Negotiation Act, Section 287.055 Florida Statutes. 4. On July 17, 1991, Hollywood approved the recommendation of the selection committee and awarded the contract to ENGINEER for the 1/1, the SSES, and the rehabilitation engineering work. In December 1991, the ENGINEER finished the III work. In January and February 1992 the Large Users, including CITY, reviewed the 1/1 report and agreed upon commencing with the SSES program.

J Mr. Robert J Palm October 21. 1993 5. During March and April of 1992. the Large Users, including CITY, conducted negotiations with ENGINEER to define the SSES scope of work, engineering costs and the unit cost were agreed to by all Large Users. 6. On June 12, 1992, a contract was signed for the required Sewer System Evaluation Survey and Rehabilitation Engineering between the ENGINEER and Hollywood (copy attached). 7. In accordance with the above agreement, all 1/1 and SSES work performed in the City of Dania is being paid for through Hollywood's 1991 Bond Issue. Final allocation of costs for each Large User will be made by Hollywood upon completion of the SSES reports. I 8. During the performance of the SSES work, the CITY decided to proceed with the II rehabilitation work as soon as each repair methodology and location was established. Repairs were performed by CITY personnel and outside contractors. As part of rehabilitation engineering, ENGINEER performed periodic field inspections of this work and coordinated with contractors and CITY. The attached invoice covers engineering j costs for the additional work requested by the CITY. 9. It is anticipated that additional expenditures (approximately$8,720)will be incurred by the CITY In 1994, when post-repair flow monitoring is performed and a final project report is completed in accordance with EPA requirements. 10. By performing this fast track repair program and providing contract administration and full- time inspection, CITY has realized substantial savings in the rehabilitation engineering costs.
