utilities/Site Projects
NTA Contracting Inc. is an industry leader for underground utilities and site-work of all scopes and sizes. From subdivisions to pump stations to major infrastructure projects, we have earned an outstanding reputation for quality projects from start to finish.
Sump Installation
NTA was one of the first companies to specialize installing sumps, also know as drywells. We have the capability of excavating a 7.5′ +/- diameter 37′ deep excavation, with our one of a kind hydraulic clam machine. NTA is able to accomplish several jobs with one machine, such as: Surgically Precise Demolition, MH Over Existing Pipe, Caisson Manholes 14-20′ Diameter, and Sumps / Sed Installs.
Sump Testing
To ensure the optimum sump and storm sewer pipe performance, determine the in-place capacity of the sump downstream from the sedimentation manhole for each sump system. Testing takes place after a sump has been constructed.
