Well #32 Rehabilitation Engineering Servires <br />We have broken down our approach into three <br />parts, Well 32/Morrison Park, the conveyance <br />pipeline and the John Garthe Reservoir site. Each <br />element has challenges that the project team will <br />need to evaluate and work through with the City. <br />Summarized below are the key critical elements <br />that the project team has identified for each site: <br />1. Incorporating an aboveground well facility <br />that is functional and easy to maintain while <br />maintaining the use and functionality of Morrison <br />Public Park, <br />2. Incorporating the recently constructed low <br />impact design (LID) in and around the park's <br />parking lot and incorporating the LID design <br />into the new improvements and carrying the <br />landscaping theme throughout the new well site. <br />3. identifying the construction impacts to the park <br />and surrounding residential area and develop <br />criteria that mitigates/minimizes these impacts to <br />the park use and the residents. <br />it ► <br />1. Pipe size based on either using a pressure <br />sustaining valve at John Garthe Reservoir <br />or frictional losses in the pipe to provide <br />backpressure and keep the well on its pumping <br />curve. <br />2. Santiago Creek crossing whether the bridge can <br />be utilized or the pipeline needs to be bored and <br />jacked below the creek crossing. <br />3. Traffic control on Bristol Street and Memory <br />Lane. Bristol Street is a heavily congested utility <br />corridor and a major thoroughfare for traffic. <br />1. Modification of control system to incorporate <br />Well #32 and the dedicated communication fiber <br />optic conduit. <br />2,. Connection of the new. Well #32 pipeline to <br />the existing reservoir fill line and locating the <br />pressure sustaining valve, if required. <br />3. Fiber optic conduit routing through the site and <br />into the existing control room. <br />
