CollectionGwin, Dobson & Foreman has designed hundreds of collectionsystems in rural and urban communities.

We use the latest in GIS/GPS mappingtechnologies and design software tooptimize system layout and cost.

For existing collection systems, we can accurately assess hydraulic conditions through flow monitoringand modeling to determine the mostcost-effective rehabilitation solutions.

GD&F is fully qualified in the design of trenchless technologies for sewersystem rehabilitation including slip-lining, pipe bursting, directionalborings and cured-in-place pipe.

ConveyanceGwin, Dobson & Foreman’s design experience will ensure long-termperformance and reliability of allconveyance systems components.

This includes pumping facilities, interceptor and outfall sewers, andcombined sewer overflow control.

Our expertise goes far beyond desk-topoffice analysis. GD&F has years ofpractical knowledge in pumping systems application that is essential to effective design.

GD&F uses the latest in control systemtechnology to optimize performanceand efficiency. We tailor control systemsto your operational needs and budgetrequirements.

GD&F is a leader in the control ofstormwater and combined sewer systems, from Best Management Practices techniques to CSO analysisand control facilities. GD&F has designed sophisticated CSO storageand pumping systems and combinedsewer separation projects.
