TSi served as geotechnical engineer, planning and executing drilling, sampling, testing, and analyses, and producing a final report. The approach uses three tiers of storage basin sizes with green infrastructure concepts and strategic sewer separation to reduce the number of overflow events. Most of the improvements are along the streets but some improvements are on properties. The primary geotechnical concerns are the presence of fat clay and shallow bedrock which limit the infiltration of stormwater. https://images.squarespace-cdn.com/content/v1/599b973659cc682bd65d8d1f/1506109205050-Y8X9T71E0CR4KD31GGN2/Belton+MO+WWTP.jpg Water Resource Services - Wastewater Treatment Plant (WWTP) (Copy) Wastewater Treatment Plant (WWTP) Client: City of Belton Location: Belton, Missouri This project consisted of constructing an influent pumping station (IPS), IPS electrical building, and headworks facility structure at the Belton WWTP, as well as construction of an access road for the IPS facility.

TSi provided recommendations for foundations, settlement estimates, seismic considerations, dewatering, excavation, and fill replacement. https://images.squarespace-cdn.com/content/v1/599b973659cc682bd65d8d1f/1506108949981-S4KJFZMQKPWX5F4CORC3/Middle+Blue+Green+Infrastructure_Mega+Industries+web.jpg Water Services - Middle Blue River Green Infrastructure (Copy) Middle Blue River Green Infrastructure Client: City of Kansas City Location: Kansas City, Missouri The project provided for design of up to 3,000,000 gallons of stormwater storage in an effort to meet both the Percent Capture of Wet Weather Flows and Performance Criteria set forth in the Federal Consent Decree pertaining to the Kansas City Overflow Control Program. TSi served as geotechnical engineer, planning and executing drilling, sampling, testing, and analyses, and producing a final report. The approach uses three tiers of storage basin sizes with green infrastructure concepts and strategic sewer separation to reduce the number of overflow events. Most of the improvements are along the streets but some improvements are on properties. The primary geotechnical concerns are the presence of fat clay and shallow bedrock which limit the infiltration of stormwater. https://images.squarespace-cdn.com/content/v1/599b973659cc682bd65d8d1f/1506109205050-Y8X9T71E0CR4KD31GGN2/Belton+MO+WWTP.jpg Water Services - Wastewater Treatment Plant (WWTP) (Copy) Wastewater Treatment Plant (WWTP) Client: City of Belton Location: Belton, Missouri This project consisted of constructing an influent pumping station (IPS), IPS electrical building, and headworks facility structure at the Belton WWTP, as well as construction of an access road for the IPS facility.
