Utility Master Planning

In order for any utility to provide safe and reliable utilities to its customers today and in the future, a utility master plan is vital. Johnson Engineering assists public and private utilities by determining and documenting current site and building conditions, usage, and capabilities. The goal is to determine the future use of the project and formulate an on-site layout of a system. We also provide systematic and useable plans for phased implementations or decommissioning of systems.

Water Distribution Facilities

When turning on your home faucet, you want to be sure that the water you are drinking is safe. Our utilities group understands the concerns regarding the safety and reliability of utilities. Johnson Engineering can provide the planning, preliminary design, hydraulic analysis, survey, design, permitting, bidding services, and construction phase services for any size potable water system. We have designed 36-inch diameter mains and systems over 17 miles in length. Our team also evaluates alternate materials and construction methods, such as directional drilling and pipe bursting, in order to increase constructability and to reduce cost.

Wastewater Collection

Wastewater collection systems provide safe collection and transmission of wastewater in a manner that protects the public and the environment. Johnson Engineering provides the planning, preliminary design, hydraulic analysis, survey, design, permitting, bidding services, and construction phase services for wastewater collection systems. We specialize in large capital improvement projects that involve gravity expansion and replacement for both municipalities and private utility companies. We have designed utility improvements project consisting of up to 90,000 linear feet of gravity sewer main and five lift stations.

Hydraulic Modeling

Hydraulic modeling is an essential tool in understanding a utility systems behavior. This ensures that water and wastewater systems we design are the most viable and reliable system for today and future growth. It can also be used as a tool to assess performance, development of rehabilitation programs, and support of permit applications. Johnson Engineering can provide the necessary hydraulic modeling analysis that includes field calibration, utilizing pressure data loggers, and ultrasonic flow meters, to ensure model-predicted performance reasonably agrees with measured field performance. Our model results are overlaid on aerial imagery, presenting results in a visual perspective.

Pumping Facilities

Johnson Engineering has the expertise to design pumping facilities to meet the needs of large and small developments. We have designed master pump stations to serve approximately 8,000 single and multi-family home, which are capable of conveying a peak flow of up to 4,000 gallons per minute. We are equipped to provide the planning, design, permitting, bidding services and construction phase services for most any size pumping facility.

Subsurface Utility Exploration (SUE)

SUE is a process that allows us to identify existing utilities during design. This helps avoid costly conflicts of utilities that may not have been found until construction. We currently provide two levels of service related to subsurface locating; Ground Penetrating Radar (GPR) and StarVAC vacuum excavation. The GPR is a highly versatile, noninvasive subsurface imaging unit. This instrument is typically used first to reveal underground utility lines and provide various images for future use. The StarVAC is then typically used. This machine uses a high-pressure water jet along with a vacuum system to quickly uncover utilities. Uncovering these utilities allows us to record the exact size, composition and condition. This information can then be implemented into our Geographical Information System (GIS). Digital photos can be taken of all of the exposed utilities to assist in the construction of the proposed project.
