Common-wall design saved 30% to 40% in construction costs

摘要

The Claiborne County Utility District in Tazewell, Tennessee, USA, saved up to US$ 2.7 million when building its new wastewater treatment facility. Long-term savings in future expansion costs, necessary process piping and energy costs will further increase possible savings. One year ago in February 2004, the Utility District went online with its new Hexa-Ditch treatment plant. The patented plants use a common-wall design, which allows for a less expensive expansion when needed. The average daily flow in the district is four million gallons per day (mgd), but the plant had a capacity of 1.3 mgd. In addition, the treatment plant saved the Utility District 30% to 40% on initial construction of the structure, 75% to 90% on process piping, and will help save the district up to 70% on energy costs.
