Specifications include, but are not limited to: The existing 15-inch diameter sewer line in Glendale Avenue between 91st and 99th Avenues is approaching its design capacity and there are several development areas upstream of this sewer line that will increase flows once developed. To meet future demands, a preliminary study has indicated that the existing collection system must be improved. The most viable alternatives included: upsizing the line in Glendale Ave from 91st to 99th Avenues; re-routing flow from Glendale Avenue to Bethany Home Road via 91st Avenue; or building a new lift station to divert flow from Glendale Avenue to 91st Avenue by routing additional flow to the existing Desert Diamond lift station.
