Prepared construction drawings and specifications for a 400 gpm boiler feed water system. System included strainers, steam heat exchanger, three ceramic membrane filter skids, four water softener units, four reverse osmosis skids, compressed air system, chemical treatment pumps and storage tanks, water and brine storage tanks, required piping/mechanical systems, and building with HVAC system.

Hard Hat provided engineering, design, procurement, installation, and construction services to upgrade the existing domestic water filtration plant. A 100,000 gallon potable water storage tank was installed, including subbase foundation, tank overflow pipe and splash pad, safety ladder with cage, chlorine meter, and site gauge. Also installed were a dual set of 25 hp effluent pumps, backwash pump, and influent pressure relief valve. Hard Hat oversaw construction, including building expansion, piping, and electrical and control. Hard Hat was responsible for start-up and test-out, as well as providing an O&M manual for the system.

Hard Hat served as the project engineer for a 100 gpm groundwater pump and treat system. System treatment train included greensand filtration, air stripping, and granular activated carbon. Designed all 51 extraction wells in three separate aquifers, 6 lift stations and metering vaults, piping network, and treatment plant. The plant included two separate treatment streams in order to segregate high-strength wastewater, requiring additional chemical addition and recycle to achieve treatment objectives and discharge criteria. The design included all civil site work, concrete, pre-engineered building erection, piping, valving, pumping, tanks, and control system and logic to operate system continuously, even while backwashing was conducted. The primary treatment system pumps operated on variable frequency drives, and were paced on tank level to maintain continuous flow throughout the plant.

Hard Hat performed an investigation of an anhydrous ammonia release at this Ag Chem facility, and conducted the environmental cleanup. The project included geotechnical and chemical soil sampling, excavation of over 1,000 cubic yards of contaminated soil, backfilling and construction of a reinforced concrete drive and parking surface, and the installation and operation of a soil vapor extraction system to remove ammonia from the soil and groundwater. The project was successful in receiving a review and approval from the Illinois EPA and the issuance of a No Further Remediation Letter by the IEPA.
