K-3 - Professional Services Agreement with MSA - Water Treatment Plant

ATTACHMENT A: SCOPE OF SERVICES Project Background The City of Tiffin has extremely hard water, with raw water hardness at 500-600 mg/L. Currently, the City of Tiffin is using an ion exchange process to remove radium and some hardness, reducing hardness to approximately 250 mg/L. As hardness of 250 mg/L is still considered very hard water, there have been complaints from customers about finished water quality. The Iowa DNR has also imposed a chloride limit at the wastewater treatment facility. There is currently no wastewater treatment technology that can economically remove chlorides. As such, reduction of chlorides in the City’s wastewater discharge must be accomplished by eliminating drinking water-softening processes that contribute chlorides to the water. Chlorides are being added to the water by the City’s ion exchange process and by residential/commercial water softeners. The City of Tiffin commissioned MSA Professional Services to prepare a Preliminary Engineering Report (PER) in support of an IDNR Drinking Water State Revolving Fund Loan. A reverse osmosis treatment technology pilot test, as required by the IDNR, was conducted by Harn in conjunction with this PER effort. The PER will be finalized upon receipt of Harn’s pilot testing report. The recommendations of the PER are for the City to proceed with the design and construction of a reverse osmosis treatment facility. Project Description The proposed project consists of the design of a Reverse Osmosis Water Treatment Facility to address the presence of hardness of the raw water in the City of Tiffin, Iowa. The project would include a new building and clear well located immediately adjacent to the existing water treatment plant, on the same City-owned parcel of land, to house the water treatment facilities. Modifications to the existing water treatment plant include addition of a breeze way, chlorine room, breakroom and existing equipment to be reused or removed. Conceptual drawings attached show a general layout of the proposed improvements, subject to change as design progresses. In order to assist the City with this project, MSA will complete the following scope of work: SCOPE OF SERVICES 1. Project Management and Administration a. Project Management i. Manage and coordinate project team, budget, and schedules. ii. Prepare and submit invoices. Invoices shall be submitted monthly and are payable within 30 days of receipt. b. Correspondence i. Maintain communication with Owner and stakeholders on project. ii. Provide regular design progress updates upon Owner request. iii. Coordination with the Iowa Department of Natural Resources (IDNR) for design and permitting. iv. Coordination with the State Revolving Fund on Intended Use Plan Application and SRF Environmental Checklist. v. Coordination with Electric Utility on available power source. vi. Coordination with City representatives to collect information and request input on design decisions. c. Quality Assurance/Quality Control i. Employ documented quality-assurance/quality-control procedures throughout project.
