Site work and new construction of a water / sewer project in Hartford, South Dakota. Conceptual plans call for the construction of a water / sewer project; and for site work for a water / sewer project.

As of January 21, 2022, a design firm has not been selected as of yet. Bidding and construction is estimated to take place in 2023. *The closed solicitation has been included below for reference: The City of Hartford, South Dakota is seeking qualification statements from interested engineering firms for design, bid and construction administration of a Wastewater Treatment Facility. The work is anticipated to begin as soon as possible. Hartford's current wastewater treatment facility was built in 2000. It is in the southeast corner of the community on the north side of Interstate 90 and east of Western Avenue. The wastewater treatment facility consists of two aeration cells and three tertiary lagoons. All the wastewater in Hartford is pumped, by the assistance of 2 minor lift stations, to the city's Main Lift Station and then to the wastewater treatment facility. Prior to entering this main lift station, the sewage is pretreated via a mechanical bar screen. After being pumped to the wastewater treatment facility the sewage enters the aeration cells and then passes into the tertiary cells. The system operates under Surface Water Discharge (SWD) Permit #SD0021750 and is permitted to discharge to an unnamed tributary of Skunk Creek. The facility was designed for a mx population of 4,550 and has a max storage volume of 78 million gallons. The aeration cells A and B both have a water surface area of 1.85 acres. Tertiary cell one has a water surface area of 14.9 acres, tertiary cell two has a water surface area of 14.4 acres and tertiary cell three has a water surface area of 12.6 acres. The aeration cells are 20 feet deep. The tertiary cells all have an effective storage depth of six feet. Typically, the dikes on the tertiary cells are eleven feet deep. The top three feet are for freeboard and the bottom two feet are for residual storage resulting in an effective storage depth of six feet. Freeboard is used as a safety factor and the water level should never be into the freeboard. The freeboard also keeps wave action from overtopping and breaching of the berm. A Master Plan for Wastewater Collection and Treatment was completed in 2017 and will be available for reference. This study indicated the need for an upgraded wastewater treatment facility. The city's current treatment facility is reaching its life expectancy and issues such as high flows, stricter discharge limits, and algae buildup will make this facility obsolete at some point. The City of Hartford has determined that a new wastewater treatment facility would be in the best interest of the city. Land for a future Wastewater Treatment Facility has been secured and annexed into the city. This land consists of 2 parcels on the west side of Exit 390 along Interstate 90. Fifteen acres to the north of the interstate and twenty acres to the south of the interstate. Due to the large scope of the project and amount of tax dollars involved, the city is seeking requests for proposals from interested engineering firms for design, bid and construction administration of a new Wastewater Treatment Facility. All inquiries regarding this RFQ should be submitted via email to City Administrator Teresa Sidel - cityhall@hartfordsd.us no later than 3:00 p.m. Friday, August 28, 2020. The City of Hartford will review the proposals and rank the firm based on the following criteria: 1. Overall Quality of Proposal (10%), 2. Relevant experience of the firm, assigned personnel and its subcontractors (25%) 3. Understanding of the Project and Technical Approach (25%), 4. Local resource during and after the project completion (20%), 5. Cost Effective (10%), 6. Funding and Grant experience (10%), As part of the preparation of the Statement of Qualifications, firms may schedule to review hard copies of plans and documents at Hartford City Hall during the business hours of 8:00 a.m. to 5:00 p.m. by calling the City Administrator at 605-528-6187.
