Survey studies water and wastewater’s customer rates in large cities
Water and wastewater bills for residential use across the country have increased at a steady rate since 2001, according to a survey released Tuesday by Overland Park, Kan.-based Black & Veatch. The company’s sixth “50 Largest Cities Water and Wastewater Rate Survey” highlights customer charges for water and sewer service for residential, industrial and commercial customers.
The company’s analysis of the 2010 survey results indicates the average annual increase in typical residential water bills is approximately 5.3 percent from 2001 through 2009, while the increase in typical residential sewer bills is approximately 5.5 percent. “This survey is a tool for managers of water infrastructure to see how their rates compare with national trends,” said John Kersten, associate vice president and water industry lead in Black & Veatch’s management consulting division. “The primary source of income for these utilities to pay for operating, maintaining, expanding and updating their infrastructure is through water and sewer rate collections, which must be continuously adjusted to address rising costs.”
The analysis cites five key issues that influence rates:
• Commodity price increases, primarily in electricity, chemicals and natural gas costs, which are leading contributors to operating and maintenance costs of water and wastewater facilities.
• Lower consumption and high fixed cost. In general, demand or a consumer’s use is declining while many utility costs, such as debt service, are fixed. Because most pricing structures include volume-based charges, revenues are declining while costs are not.
• Benefits. Pension obligations and health care benefits are prompting an increase in labor costs.
• Influence of wastewater legal action. Significant capital programs are being implemented in most major cities to comply with legal action related to wastewater system performance.
• Aging infrastructure. Updating and replacing aging infrastructure are significant costs for most water and sewer utilities.
