existing control system with an ultrasonic or submersible level transducer, addition of a low <br /> water level float, incorporation of low water level float and high water floats into back -up <br /> control, intrinsic safety barrier and vented conduit for floats, new alarm light, and all new <br /> wiring. <br /> C. Site Improvements (see photos) <br /> The existing site is extremely dangerous and is not conducive to maintenance work. The <br /> site was previously raised approximately five foot. A "moat" or barrier wall was built <br /> around the existing station when the grade was raised. The existing wetwell top slab needs <br /> to be replaced. A new six foot diameter manhole section should be added to raise the new <br /> top slab with hatches to grade. The existing "moat" should be filled with sand and the road <br /> extended to the new top slab. New control panels would be installed at grade. <br /> The existing fence could be salvaged and reinstalled, or removed completely from the site. <br /> New contours blending with the adjacent lot should be considered, as well as some <br /> landscaping. Generally, some interaction with the adjacent home owner is well worth the <br /> effort from a public relations stand point. We recommend meeting with the adjacent home <br /> owners to discuss proposed contours and landscaping. <br /> Cost Estimate <br /> A cost estimate has been prepared as a preliminary guide for the City's budgeting purposes. As the <br /> project is designed and City input is received, the scope of the project and associated costs would be <br /> modified to reflect the changes. See cost estimate at the end of this report. <br /> Conclusion <br /> The condition of the existing equipment is such that replacement will be required. The existing wet <br /> well can be reused but should be raised to a new grade. The existing forcemain would be reused <br /> and would not be replaced. <br /> At this time, it would be appropriate for the Council to order preparation of plans and specifications <br /> for replacing the existing lift station equipment. A possible schedule for the project is shown <br /> below. <br /> Prepare Report September 28, 1999 <br /> Order Plans and Specifications October 13, 1999 <br /> Approve Plans and Specifications November 10, 1999 <br /> Open Bids December 3, 1999 <br /> Award Contract December 8, 1999 <br /> Begin Construction April 2000 <br /> Complete Construction June 2000 <br />
