2019 Small Capacity Constraints I

Replacement of approximately 13,500 LF of small diameter sanitary sewer by Open Cut and boring Construction methods, installation of new manholes, rehabilitation of existing manholes, and two siphon structures at 8 project sites. Site-1: Babcock Rd: The existing 8-inch Vitrified Clay sanitary sewer pipe has depths of 0-5 vertical feet will be replaced with a 12-inch sanitary sewer line of varying slopes, a total of approximately 556 LF using open cut excavation method. Site-2: Jackson-Keller: This site includes 20 LF of 15-inch and 14 LF of 10-inch interconnections at two locations by open cut construction method at a depth of 7-18 vertical feet. The construction also includes abandonment sanitary sewer manholes, sewer mains and siphon piping and siphon manholes. Site-3: Midcrown Drive: Approximately 1,216 LF of existing 10-inch sewer line need to be replaced with 12-inch and 15-inch sewer lines. The construction also includes 115 LF of 30-inch steel casing by boring at the creek crossing. Site-4: N. Flores & Huisache: Approximately 534 LF of existing 8-inch line will be replaced with 12-inch line at a depth of 8-14 vertical feet. Work in alley with nearby power poles requires coordination with CPS. Site-5: Beryl St: The existing 10-inch line needs to be upgraded to 15-inch line. The piping upsize will be by open cut construction at a depth of 6-11 vertical feet. The proposed 15-inch line that will cross beneath the concrete drainage channel at Eland Drive will connect to an existing 15-inch line thru opencut installation and replacement of drainage segment. The improvements at this site include 2,865 LF of 15- inch line and 289 LF of 30-inch steel casing for water line crossings. Site-6: Wilson and Manor Drive: Approximately 1,100 LF of 8-inch line will be replaced with 15-inch line by open cut construction at a depth of 7-12 vertical feet. Construction work includes work in alleys and require coordination with CPS for pole bracing. Site-7: Piedmont Site: A new siphon is proposed to cross beneath the existing box culverts at Lennon and Merrimac Ct nearby the existing siphon. The site improvements include approximately 3,394 LF of 12-inch sewer line and 1,365 LF of 8-inch sewer line by opencut construction. The sewer line installation shall be accomplished at varying depth of cut from 8 feet to 23 feet (23 feet depth of cut of approx. 300 LF). Sewer line installation within a 15-inch steel casing for drainage crossings. Site-8: Yolanda Site: The proposed improvements include abandoning the existing siphon on Yolanda and Bernice St. and installation of approximately 1,302 LF of 15-inch and 1,230 LF of 8-inch sewer line and one new siphon on Aurora and Yolanda. The depth of cut ranges from 7 feet to 18 feet. 60 LF of sewer line installation within a 18-inch steel casing due to proximity to CPS towers.
