recirculating textile filter system(Figure 7) with four pods,40 square-foot each, provides advanced treatment. The treated effluent is discharged into 960 linear feet of disposal field. The quality of the effluent prior to subsurface disposal is expected to equal or exceed what was previously discharged, directly into the river, by the package plant. This system is expected to discharge BODS and TSS of less than 10 mg/l. Average results are shown below. The control panel is outfitted with a remote telemetry unit that monitors and records flow and pumping data, as well as alerting maintenance personnel of any alarm conditions.

Its facilities include cabins, bathhouses, and lodges. Prior to the installation of the textile filter, wastewater was collected in holding tanks, the contents of which had to be pumped and hauled throughout the summer. The original gravity septic tank systems had failed several years earlier and were shut down by the Arizona Department of Environmental Quality due to inadequate treatment in the shallow, dense clay soils and to contamination of a nearby stream. Phase I,completed in May of 1999, consists of an effluent collection system and textile treatment system similar to the Steamboat Ranger Station's, although on a larger scale. The design-engineering firm, Agra Infrastructure, originally selected a recirculating sand filter for treatment, but had difficulty locating a local source of good quality media. The treatment system is designed to handle I2,000 gallons per day. Results for the summer of 1999 are as follows: NTP-FLT-TRB-ESB-HLB-1 ZW Page 9
