Keystone Avenue Sanitary Sewer Trunk Replacement
The City of Reno Sanitary Division investigated and identified the Keystone trunk sewer as a deteriorated line in need of immediate replacement. CFA was contracted to provide surveying, final civil design, bid assistance, and construction management services for this project.
CFA was responsible for all research, surveying, planning, and design for 6,000 lineal feet of new sewer main. Since Keystone Avenue is a heavily-traveled roadway, many design challenges existed including traffic control, business access, and space constraints due to the many existing underground utilities. CFA surveyed and mapped all existing utilities and improvements, prepared a sewer capacity analysis based on existing and proposed development, and produced plan and profile construction drawings for the project. In addition to the gravity sewer design, CFA was responsible for the relocation design of approximately 2,000 lineal feet of conflicting water main owned by TMWA.
The City of Reno and Truckee Meadows Water Authority (TMWA) entered into an interlocal agreement to construct the sewer and water mains under one contract. CFA administered the contractor bidding process and provided construction observation and administration services for the estimated $7.3 million construction project. Construction started in February 2007 and was completed in June 2007. |

Lakeside Drive Sanitary Sewer Trunk Replacement
A City of Reno investigation has identified several issues associated with the existing Lakeside Drive trunk sewer including limited capacity and backwater deficiencies. CFA is under contract with the City of Reno to provide topographic surveying, civil design, contractor bidding coordination, construction staking, and construction management services.
Design tasks for this project include preparation of a sewer contribution and capacity analysis for the existing and future developed drainage areas. CFA’s engineering staff will create a sewer distribution model using AutoCAD-based software and compare the results to actual flow data compiled by our field surveyors. The data compiled for the sewer capacity analysis will be utilized for final design of the new sanitary sewer trunk line.
Along with the preparation of final construction drawings and specifications, CFA will also coordinate the bidding process and oversee all construction activities. Construction is anticipated to commence in February 2009. |

Master Sanitary Sewer Studies
CFA has performed numerous master sanitary sewer studies in conjunction with a wide range of development projects. In general, a master sanitary sewer study includes the following elements: analysis of the existing system, calculations of peak flows from the development, analysis of future flows potentially reaching the site from upstream, layout of the required infrastructure for the development, and recommendations for capacity improvements downstream, if needed.
With the continual expansion of development boundaries, and the tendency for in-fill projects to increase density over what was originally planned, it is often necessary for the consultant to determine whether the existing sewer system has adequate capacity for the proposed project. In other cases, the sewer system is installed in anticipation of development and the consultant must design the sewer to economically meet present and future needs. A sampling of CFA projects with significant sanitary sewer components includes the following:
- ArrowCreek (1,090 homes)
- Spanish Springs Business Park (411 acres)
- Summit Sierra Phase 1 (72 acres)
- Bear Creek Subdivision (28 homes)
- City Center Apartments (258 units)
- Montebello Apartments (864 units)
- Sterling Ranch Subdivision (198 homes)
- Heron’s Landing Subdivision (162 homes)
- FireCreek Crossing (70 acres)
- Curti Ranch (567 units)
- University of Nevada, Redfield Campus

Sanitary Sewer Lift Stations
The need for a lift station is usually dictated by topography. When the sanitary sewer system reaches a depth that is too low to drain into the receiving sewer or when the required sewer route is too long, too deep, or too costly to construct, a lift station is designed to pump the effluent to a higher elevation. The effluent is pumped through a force main that is designed for pressurized flows similar to a water main. The force main may have a length of only 10 feet or as much as 10,000 feet or more. For sanitary sewer lift stations serving subdivisions, the local entities frequently require an economic analysis of life-cycle costs over a 50-year period to show that the cost to construct and maintain the lift station will be less than the cost of a deeper or longer gravity sewer system. CFA has prepared designs of sanitary sewer lift stations for the following projects:
- Spanish Springs Business Center/Pebble Creek Subdivision
- Sage Ridge School, Southwest Truckee Meadows
- Kings View Estates, Reno, Nevada
- East Meadows Subdivision, Kirkwood, California

Galena Water System
CFA staff completed the Phase 2 final design for this water system, which includes approximately 1.5 miles of transmission piping, well house site development, jack-and-bore under the Mt. Rose Highway, and U.S. Army Corps of Engineers permitting for a crossing of Whites Creek. The water from this system serves the domestic supply, fire storage, and supplemental irrigation needs of properties in the Mt. Rose Highway area. CFA obtained the entitlements for the well houses, provided the landscaping plans, and created photo simulations of the proposed structures for use during the public hearing process. The westerly well house was screened with berming to reduce the visual impact to adjacent residences. This system was constructed with private funds and was dedicated to Washoe County. Phase 3 consisted of the design and construction of an additional 6,000 lineal feet of 8-inch distribution waterline. This phase connects two separate water systems (Washoe County and the South Truckee Meadows General Improvement District). CFA obtained all entitlements and coordinated the construction, which occurred in 2001-02.
The engineer’s estimate for Phase 2 was $1,600,00. The award amount was $1,438,915 and the construction cost was $1,468,713. For Phase 3, the engineer’s estimate was $425,000, the award amount was $389,163, and the construction cost was the same as the award amount. |

Skylawn Water System
In conjunction with the design and construction of the new Skylawn Funeral Home in San Mateo, California, CFA designed a completely new potable water system to provide domestic water to the new funeral home and several existing buildings throughout the cemetery, a separate non-potable fire water system to provide water for the sprinkler system for the new funeral home, and hydrants for additional protection of the funeral home and the existing cemetery administration building. The design includes an approximately one mile long transmission main from the well to a below-grade storage tank, a gravity distribution system to all buildings within the cemetery, and booster pump stations where required. The fire water system includes construction of a new discharge line from an existing reservoir and distribution lines to the funeral home and hydrants. The water system will be constructed concurrently with the funeral home project. |

Northwest Tank and Transmission
Line
 Award-Winning
Project
CFA was responsible for all phases of planning and design for this water system in the Spanish Springs Valley. The project included 6,000 lineal feet of 14-inch diameter transmission line crossing both private land and Bureau of Land Management property and two water storage tanks. The tanks, one at 1.5 million gallons and one at 1.0 million gallons, are located on BLM property in areas that contain slopes exceeding 20 percent. The civil infrastructure design included an access road that was designed to withstand the 100-year flood and several pressure reducing stations on the water main servicing new developments. Construction costs for this project exceeded $1 million. In 1999, this project was given an Award of Distinction for Excellence in Environmental Design by the Washoe County Design Review Committee.
In addition to the water system, CFA was responsible for the preparation of a water master plan report for approximately 2,990 homes, 500 acres of industrial park, and 50 acres of commercial property in the Specific Plan area. Existing systems were analyzed and a plan was developed to serve the future needs of the area. Cost estimates were prepared to establish the feasibility of several development alternatives. |
