The second reuse of municipal wastewater for recreational purposes is becoming a reality in Lubbock, Texas where a series of small lakes will be fed with percolated wastewater which was reused previously for irrigation. In conjunction with the city's project, Texas Tech University has constructed a model of the Canyon Lakes Project consisting of nine ponds 16 x 8 x 6 ft deep fed with percolated wastewater of comparable quality and stocked with channel catfish. Several chemical parameters of water quality (COD, NO3, PO4, CO2, and DO) are monitored on a frequent bases along with the daily logging of physical events in an attempt to provide the city with valuable information concerning possible problems and solutions surrounding the project. Only preliminary work has been done on the pilot scale study. Additional studies are in progress.
