Proiect Goals and Design Consideration: When putting together the design and the associated cost estimate the following items were kept in mind as factors that would be critical for developing an Emergency Water Supply that would operate as needed for the JWC: 1. Reliable - Ensure ability for quick MDH approval and project start-up 2. Maintainable - Minimal vulnerability and need for maintenance 3. Operator Friendly - Simple to operate to achieve maximum flow and limit negative impacts Well Location Options: There will be a total of three new wells located in Crystal and Golden Valley. The determination of well locations has not yet been finalized. The fourth well for the system will be the existing New Hope Well No 1. Two options for the location of the three new wells have been evaluated, as noted below and depicted in the referenced Figures. Option A (Two wells in Crystal See the indicated Figures o Figure 1 Crystal Well Locations o Figure 2 Golden Valley Well Location Option B (Two wells in Golden Valley) - See the indicated Figures o Figure 3 Crystal Well Location o Figure 4 Golden Valley Well Locations DESIGNING FOR A BETTER TOMORROW Bolton & Menk is an equal opportunity employer JWC Emergency Water System January 9, 2014 r Page 2 of 4 New Hope Wellhouse Renovation: The existing wellhouse in New Hope will require renovation and upgrading as part of this project. The renovation will include work to the pump base and the addition of a vertical turbine pump, motor, and line shaft as well as valving, piping and controls to make the well operational. New Wells: The contract documents will include two alternative methods for well construction as shown below. Dual Rotary Construction: This type of rig will require only two casings, a 24" and an 18". Cable Tool Construction: This type of rig will require three casings, a 30", a 24" and an 18". If desired, the bid documents for the wells can be prepared separately, ahead of the rest of the project. Potential Water Quality Issues: Potential water quality issues that may occur during use of the emergency water system are outlined below. Aesthetic Issues - Potential Impact Associated with Switching to Unsoftened/Unfiltered Water: ■ Increased Colored Water (Difficulty getting laundry white) ■ Increased Spotting on Dishes (Difficulty getting soap to lather) ■ Increased Oily Sheen on Coffee ■ Increased Taste and Odor Recommended Addition to Desisn Services Scope: In order to address potential water quality issues associated with utilizing ground water as potable water, Bolton and Menk recommends that the design of a chlorine feed system be added to the scope of services for this project. Reasons for this addition are described below. o MDH Permitting ■ Allows for quick project approval and efficient execution during the start-up of the Emergency System o Reliable / Secure / Safe ■ The equipment can be protected between emergencies and will not be in risk of damage during transport ■ The cities will have control of the reservoir and wellhouse sites which can be fenced o Simple ■ JWC can contract with a local chemical supply company to supply chlorine during an emergency.
