Provided the planned structures included an electrical building, an odor control building, and a wet well for the proposed pump station  The wet well shaft was approximately 200 feet deep with circular concrete walls to house pumps and store wastewater.The excavation for the shaft consisted of open cut to top of rock followed by rock excavation by blasting or by shoring the excavation using soldier piles and lagging system. We performed geotechnical explorations, rock coring and laboratory testing to arrive with the most cost-effective foundation system to support the construction.
