Lumos provided base mapping, potholing, geotechnical investigation, hydraulic modeling, improvement plans, specifications, permitting, construction management, construction inspection, materials testing, and construction staking for this $7.1 million sewer interceptor improvement project. Major work items included the construction of a 5 MGD sanitary sewer lift station, the installation of approximately 4,500 lineal feet of 20-inch HDPE force main, installation of approximately 1,900 lineal feet of gravity sewer main ranging from8-inch to 36-inch, 48-inch and 42-inch steel conductor casing jack and bores under UPRR main lines, rehabilitation, replacement and new construction of manhole structures, installation of a custom splitter box structure, abandonment of existing sanitary sewer interceptor pipelines and structures, and traffic control.The project required a maximum bypass pumping flow rate of 9.75 MGD during tie-ins and replacement of existing pipelines.
Farr West was utilized as a sub-consultant to design the associated sanitary sewer lift station site. Work included design of the interconnecting piping, wet well, submersible pumps, emergency storage, backup generator and other pertinent facilities and equipment.Lumos’ design and construction staff worked cohesively as a team to identify and resolve matters beforethey became problematic. Additionally, Lumos provided coordination between numerous entities,consultants and contractors; enabling a seamless project with multiple stages and complexities.
Challenges included working 24-hour shifts on Wells Avenue to accelerate the project schedule and minimize lost revenues to adjacent businesses. Timing of the completion of the gravity lines and force main was critical with the commissioning of the new lift station as flows were rerouted during design and had to be “temporarily” diverted until the lift station was operational.
Tony Angelopoulos, NDOT, “Wanted to thank Lumos and the City of Reno for their coordination efforts and the high quality workmanship on Wells Avenue. The project turned out great and the accelerated schedule and construction practices provided for minimal impact to the businesses and traveling public”
