Electronic Scale Prevention | WWD - Water & Wastes Digest
Electronic Scale Prevention In one of its biggest public works projects ever, the city of Las Vegas spent $37 million to construct the Durango Hills Water Resource Center. This state-of-the-art facility, which started service in 2001, collects municipal sewer wastewater and treats it to standards that make it safe for irrigation of 11 area golf
Water & Wastes Digest serves readers in the water and wastewater industries. These people work for municipalities, in industry, or as engineers. They design, specify, buy, operate and maintain equipment, chemicals, software and wastewater treatment services.

The Nakusp Ledge was published in Nakusp, in the Central Kootenay region of southeastern British Columbia, from October 1893 to December 1894. The paper was subsequently published as the Ledge both in New Denver, from December 1894 to December 1904, and in Fernie, from January to August 1905. The Ledge was published by Robert Thornton Lowery, a prolific newspaper publisher, editor, and printer
