The Paducah McCracken Joint Sewer Agency asked us to provide engineering assistance to eliminate a problem with hydrogen sulfide gas in their dewatering building. The issue was caused by in-adequate ventilation resulting in noxious fumes and extreme corrosion within the building. Matrix replaced their existing ventilation system and provided hoods specifically designed for each piece of equipment in the building. The hoods were designed to adequately ventilate yet allow room for cleaning and maintaining of the dewatering equipment. The Director of the JSA informed us that our design helped the interior smell like “pristine mountain air” compared to the old system.
