Floor Pits The volume within the wastewater pits is controlled by level controls. A vent for the effluent piping is located in the clean floor pit but the water stays well below the piping. Some possible release scenarios include: • Floor pit overflow Wastewater Treatment Room Wastewater coagulant is purchased in totes and transferred to a tank inside the WWT room. Flocculant, Bentonite Clay and Sodium Percarbonate are purchased as dry powder and kept in bags. Make-up tanks equipped with mixers are used to prepare dilute solutions of bentonite clay, flocculant and sodium percarbonate. The BC1031 and IM3000 drums are stored on secondary containment inside the WWT room. Possible release scenarios include: • A hose coupling failure or leak from the hose after the tank filling operation is complete • Bulk storage tank overflow inside the WWT room. • Make-up tank overflow during the tank filling operation • Container damage during offloading, internal transport or caused by forklift impact • Sludge tank overflow • EQ tank overflow of untreated wastewater • Piping or pump failure resulting in a release of untreated or partially treated wastewater A Cintas Partner must be present during the entire duration of the make-up tank filling process. At no point should the operation be unattended. Boiler Room Water softener regeneration waste and boiler blowdown are the two main periodic waste streams in the boiler room. Boiler water conditioning chemicals are stored in this room and are periodically used in small amounts. The chemicals are stored in 55 Gallon drums on top of spill containment. A relatively small spill or leak involving those chemicals is possible. All discharges from the boiler room area drain into floor drains connected to the main floor pits and are therefore mixed with other wastewater and treated prior to discharge into the city sewer.
