Municipal Water and Waste Water
The municipal bus service for a large Southwestern city covers some 1,200 square miles of territory, operating a fleet of 450 buses and 100 vans that carry an average of 255,000 passengers a day. Every night between 11 p.m. and 5 a.m., the vehicles head to a “bus barn,” or maintenance depot, where they are washed, cleaned, refueled and, if necessary, repaired for the next day’s routes. It takes about two minutes to wash each bus, inside and out.The Challenge
For more than year beginning in October 2010, the Southwest endured one of the most severe droughts in recorded United States history. Through the first ten months of 2011, Texas, for example, received 15 inches less rainfall than average, lowering streams and reservoirs to some 50 percent of their capacities and causing devastating losses to farmers and ranchers.
Goforth Williamson Inc. provides pumps, pump repair, and field services to a variety of industrial companies and municipalities across the Southern United States. Goforth Williamson Inc., who has positive working relationships with several water and wastewater treatment plants, was contacted in 2014 by a major city’s water treatment plant; one that provides drinking water to over 4 million people in a metropolitan area. When one of the clarifier sump pumps at the water treatment plant wore out, Goforth Williamson was asked to recommend a replacement pump.The Challenge
The water treatment plant extracts fresh water from a nearby river, pumping a significant amount of sand and silt in with the fresh water. The water treatment plant must separate the water from the sand and silt in a clarifier.
A wastewater treatment plant in Alabama contacted one of their consultants to help them find a solution to a pressing maintenance issue. Municipal Consultants Inc., a Birmingham-based engineering group, has worked with several of the utility’s water and wastewater pumping stations for many years. When Trent Turner, one of the Consulting Engineers, learned about the excessive clogging issues that had been occurring at one of the wastewater treatment plant’s pump stations, his search for a solution led him to work with Morrow Water Technologies, Inc., a company that provides fluid handling equipment and support services to the municipal water and wastewater markets.The Challenge
The small pump station inside the wastewater treatment plant contained two grinder pumps in a duplex arrangement. Having two pumps in a duplex arrangement is common for most wastewater pumping stations.
