Sand filters can be included into most sanitary system designs. They can substantially increase drainfield life by cleaning and treating the effluent before it reaches the drainfield. They also allow sanitary systems to be placed in marginal soils. We install all types & sizes of sand filters, from basic gravity fed filters, to state of the art electronically controlled, pressure injection systems. Consult with your designer for details on whether or not a sand filter is right for your application.

Dike Repair-
We have the equipment and experience to build and repair dikes. We repaired this failed dike using a specialized "walking" excavator capable of working in 8' deep water, a 3 yard 100,000 lb excavator, and a 3 yard loader. Since we always have a limited "window of opportunity" when working in tidally influenced areas, timing and coordination of crews and equipment are critical.

Pump Station Installation -
We also install water & wastewater wet well pump stations, such as this dual pump system we installed in a solid rock excavation.
