In early August 2011 Denver police reported the investigation in a series of thefts of brass and copper piping from the Denver Parks and Recreation Department. About 40 backflow assemblies, expensive sections of outdoor sprinkler systems, have been stolen from city parks and parkways that summer. The thefts have cost the city thousands of dollars. The piping units are sold to recycling facilities for cash, police said. Some units are also sold to contractors to be used on private jobs.
Denver Water needed a quick reasonably priced solution to keep the water flowing while trying to fund new sprinkler systems. Because one man alone couldn’t do the job. The answer: crowdsourcing.
