Jubitz Corporation operates a major travel center in Portland, Oregon that is known nationwide for its wide range of services to truckers and tourists. Jubitz has long been a leader in environmental sustainability in the Pacific Northwest offering ultra-low sulfur biodiesel, recycling facilities, no-idle truck parking that reduces air emissions and now a state-of-the-art stormwater filtration system. With 15 acres of paved parking, Jubitz Travel Center produces large quantities of stormwater during rainy periods. Road grit, residual phosphate detergent film, metals, oil and other potential pollutants from parked commercial vehicles can be carried by stormwater to local community waters. E.coli bacteria contamination from wildlife and customers’ domestic pets may also be present.
"Managing stormwater runoff from our fully-paved truck stop facility presented unique issues, and we are very pleased that StormwateRx's system provided an adaptable and effective format for our industry's challenges,” said Vic Stibolt, vice president administration of Jubitz Corporation. "Stormwater samples before and after the installation of the Aquip and Purus systems reflect a dramatic improvement in successfully preventing potential pollutants from entering our local waterways and in meeting benchmarks for water quality in stormwater runoff."
To prevent the discharge of these pollutants to the adjacent Columbia Slough Watershed in Portland, Oregon, Jubitz Travel Center retrofit the site with a stormwater treatment train provided by StormwateRx LLC including an Aquip® Enhanced Stormwater Filtration System and a Purus™ Bacteria Polishing System.
Jubitz Travel Center drainage area is split into two main sub-basins. Each main sub-basin drains to a dedicated stormwater treatment system consisting of an Aquip 210SBE and a Purus 210V. Aquip is an enhanced media filter specifically designed for the reduction of stormwater pollutants such as petroleum hydrocarbons, suspended solids, particulate and dissolved metals, particulate and dissolved phosphorus, and other pollutants. This Purus model is a modular upgrade to the Aquip that uses ultraviolet disinfection for bacteria and fecal coliform removal downstream of Aquip. The system has no moving parts and is designed for simple and reliable stormwater service.
Untreated (inlet) and treated (outlet) water quality samples were collected during four storm events for permit compliance and to assess the level of treatment provided by the treatment systems.
The outlet water from the combined Aquip and Purus systems were measured to be below benchmark levels for all of the four storm events sampled at the facility. Inlet concentrations of phosphorus and E. coli were regularly found to exceed the permissible water quality benchmarks. Zinc, copper, and total suspended solids required treatment to meet the benchmarks on occasion. Aquip and Purus systems consistently provided the necessary treatment for each of these pollutants commonly found at truck service centers. During these four sampling events, all ten water quality constituents regulated by the Oregon Department of Environmental Quality 1200-COLS Industrial Stormwater General Permit were measured. However, only the constituents with inlet values above benchmark levels are reported.
