	Tanque Verde Interceptor, Tucson County Club to Craycroft Road and Hidden Hills Wash to Arbor Circle Pima County Wastewater Management RSE designed the 9,284-LF segment of the Tanque Verde Interceptor between Craycroft Road and Tucson Country Club and the 4,200-LF 27-inch sewer interceptor with manholes and appurtenances, including approximately 1,200 LF of micro-tunneling/boring from Hidden Hills Wash to Arbor Circle. The construction required the cooperation of private utility companies and local, county, and federal governmental agencies. The U.S. Army Corps of Engineers and county agencies were involved in the design and approval of the erosion control measures to provide protection for the pipeline and to stabilize the bank. Construction cost: $8,400,000.
	Palisades Wastewater Lagoon Replacement, Coronado National Forest, Topographical and Design Surveying, Civil Engineering, and Construction Management USDA Forest Service RSE furnished all material, equipment, transportation, labor and supervision to design the removal and replacement of the existing lagoon treatment system. Other associated design work included fence repairs, repair to the gravity sewer collection system, modifications to the reuse sprinkler system and provisions for temporary sewage treatment during the replacement of the lagoon.
	Speedway to Ajo 36-inch Reclaimed Water Route Study and Detailed Design Tucson Water RSE provided a detailed route study and pipeline design for this major reclaimed water transmission/distribution system in southwest Tucson. The route study involved a detailed evaluation and study of a 45-square mile study area for service to 80 potential reclaimed water users. The study included evaluation of a minimum of three alternate routes involving more than 15 miles of transmission mains and more than 20 miles of lateral distribution mains. User coordination included 80 school sites, parks, and industrial/commercial users. The Detail Design involved final design for 13,000 LF of 36-inch and 1,500 LF of 24-inch transmission mains and 13,000 LF of 12-inch lateral mains. Subsequent phases of detailed design will complete the recommended improvements outlined in the Route Study. Route Study, plans, specifications and cost estimates were produced. Design elements also included the design of a special crossing over the Tucson Diversion Channel. Construction cost: $21,226,000.
	Aviation/Third Avenue 48-inch A-Zone Transmission Main Design Tucson Water RSE provided construction plans with detail sheets and specifications and a cost estimate for approximately 13,728 LF of 48-inch and 1,056 LF of 24-inch transmission main together with the replacement of 12,144 LF of 12-inch, 8-inch, 6-inch and 4-inch potable water mains. Construction cost: $4,500,000.
	Sweetwater Wetlands Secondary Effluent, 36-inch and 42-inch Reclaimed Main Design Tucson Water As a subcontractor to CH2M Hill, RSE provided engineering for the pipeline design, effluent pump station design, subconsultant coordination, and construction management. RSE provided the final design for 2,500 linear feet of 42-inch and 2,300 linear feet of 36-inch effluent pressure pipeline and 650 linear feet of 12-inch backwash water pressure pipeline which included one major river crossing with casing under existing bank protection. RSE also provided the final design for a 40-mgd ultimate secondary effluent pump station. Phase I was for 20 mgd for Wetlands and recharge supply as well as a filter plant supply. The pump station design included four 200-HP units, one 40-HP pump, and three 150-HP filter plant supply pumps. Additionally, there were two 20-HP pumps for a golf course irrigation system. RSE was responsible for all pipeline and pump station civil, structural/mechanical design with coordination on electrical and instrumentation. Construction cost: $2,500,000.
	Rancho Vistoso 16-inch Alignment Study and Water Main Design Oro Valley Water Utility This project consisted of constructing a new water transmission main, with an alignment approximately 4,000 feet in length. RSE provided civil engineering services and surveying services that included surveys for design, preparation of construction/bid documents, geotechnical investigations, pre-bid and construction administration, and agency coordination and certification.
	Plant No. 1 30-inch and 36-inch Water Route Study and Detailed Design Tucson Water This $2.7 million project included a route study and detailed pipeline design for 10,000 linear feet of 36-inch transmission mains and 16,000 linear feet of 30-inch transmission mains in urban and developed areas of Tucson. The project also required boring under the I-10/I-19 interchange.
	CAP Northwest 42-inch Transmission Main Design Tucson Water RSE provided the design of 13,000 linear feet of 42-inch diameter water transmission main, including an alignment study and archeological investigation, landscape re-vegetation, cross drainage, agency and utility coordination, and Santa Cruz River lateral migration/scour analysis.
	North La Cañada 'E' Zone 16-inch Water Main Extension Oro Valley Water Utility RSE provided services for this two-phase project which included three major drainageway crossings, and a new 16-inch waterline connecting an existing 16-inch E-Zone main along Tangerine Road to a future reservoir. Phase I of this project was constructed in conjunction with Oro Valley’s public works roadway improvement project, “La Cañada Drive, Tangerine Road to Moore Road”. Phase II of this project will be coordinated with the construction of Moore Road, from King Air Drive to La Cañada Drive, as well as the construction of the E-Zone reservoir.
	Thornydale 24-inch Reclaimed Transmission Main Design Tucson Water RSE provided the design of 2,000 linear feet of 24-inch transmission main. This project included utility company coordination, cross-drainage issues, agency coordination to connect existing utilities, and construction cost estimates.
	Tangerine Road 16-inch Waterline Alterations/Replacement, La Cañada Drive to First Avenue Oro Valley Water Utility This $1.5 million water improvement project involved the design of a permanent 16-inch transmission main; and temporary and permanent modification to the existing distribution system. RSE also provided for a future 24-inch main adjacent and parallel to the 16-inch main and designed pipe crossings for the future 24-inch main. A design report outlining the proposed design and sequencing of the new water line design, including alterations to the existing system within Tangerine Road, was also prepared for this project.
	Orange Grove Park/Tangerine Acres Mainline Replacement - 4-inch, 6-inch, and 8-inch Potable Water Main Replacements Metropolitan Domestic Water Improvements District This two-phase project included the installation of more than 21,000 linear feet of 4-inch, 6-inch, and 8-inch potable water mains to service the existing northwest subdivisions. These new mains replaced the old, deteriorating, undersized water lines, which were failing to provide adequate water pressure to serve more than 260 residents. 21 fire hydrants were also installed as part of this project, providing fire protection coverage where none existed before.
