Scour valves are strategically positioned ______________?
Show answer Hide answer
Answer: B. at every depression and dead ends to drain out the waste water that may collect there
Explanation
Scour valves are placed at low points and dead ends to empty accumulated wastewater. They allow maintenance crews to flush out settled silt and debris from pipelines. Strategic placement ensures complete drainage of pipe segments during repair works. Sediments tend to settle at pipeline depressions and low-lying topographical points. Scour valves connect pipelines to nearby storm drains or natural watercourses. Opening these valves flushes out trapped deposits under pressure during maintenance.
Water distribution networks require scour valves to maintain high water quality standards. Regular flushing prevents taste and odor problems caused by stagnant pipe deposits. Municipal maintenance teams schedule periodic scouring of dead-end water mains. Street corner placement describes isolation valves used to control general water flow. Summit placement describes air relief valves used to release trapped air pockets. Rising main foot placement describes check valves used to prevent backflow.
