Highland Tank, Elevator Sump Pump Interceptors (ESP-INT) are designed to trap sediment and retain free floating oil and grease (petroleum hydrocarbons and other volatile liquids) in wastewater discharged from elevator pit sumps. ESP-INTs prevent the discharge of sediment, oil, grease and other substances harmful or hazardous to the building's drainage system, the public sewer, sewage treatment plant or other treatment processes. Elevator Sump Pump Interceptors are constructed of mild carbon steel and coated with heavy duty polyurethane for superior corrosion resistance.See details on Highland Tank's Elevator Sump Discharge Filtration System below.

Highland Tank Elevator Sump Discharge Filtration Systems recover harmful oil spills or discharges from hydraulic elevator sumps whenever the sumps are drained by a self activating pump. These systems are used in applications where strict water quality discharge regulations are mandated. They work in compliance with the EPA's sewer pretreatment or storm water programs by helping prevent petroleum products from being discharged to sanitary or storm sewers.
