If trends continue, the country will face a single-year O&M shortfall of $18 billion in 2039. Classes of unregulated compounds known as contaminants of emerging concern (CECs) are a concern for water treatment engineers, particularly pharmaceuticals and personal care products. Pumping systems, typically consuming 10-15% of energy at wastewater treatment plants, can lead to inefficient energy consumption when pumps, flow control, and motors are mismatched to treatment plant needs. 1. doi: 10.17226/10135. b. U.S. Environmental Protection Agency (EPA) (2022) How's My Waterway? Though utilities are seeking to address affordability challenges in vulnerable communities, decreasing usage due to water conservation appliances, persistent leaks from aging infrastructure, and increasing inflation have all contributed to the 24% increase in rates reported from 2008 to 2016. No. Asset management must include continuous assessment of the condition of assets and prioritize investment decisions based upon a comprehensive suite of data. Since 2008, user rates have trended upward to reflect the true cost of service and also due to dwindling revenues for many wastewater utilities. Sewage sludge includes scum or solids removed in primary, secondary, or advanced wastewater treatment processes and any material derived from sewage sludge (e.g., a blended sewage sludge/fertilizer product) but does not include grit and screenings or ash generated by the firing of sewage sludge in an incinerator. The nations more than 16,000 wastewater treatment plants are functioning, on average, at 81% of their design capacities, while 15% have reached or exceeded it. When these areas experience heavy rainfall or rapid snowmelt, the capacity of the combined system is overtaxed and results in combined sewer overflows where large volumes of partially treated or untreated wastewater bypass the treatment process and enter local waterbodies. At municipal wastewater treatment plants in the United States, raw municipal wastewater undergoes preliminary, primary, secondary, and in some cases, additional treatment to yield treated effluent and a concentrated stream of solids in liquid, called sludge. However, this method can have higher maintenance, energy and capital costs. 222 0 obj <> endobj Below are other science topics associated with wastewater treatment water use.

Over the last two decades, more than 200 of the nations largest combined sewer systems (those serving > 50,000 people) have been identified and had actions taken to reduce overflow discharges that degrade water quality. This underscores a chronic trend of underinvestment in critical water-related infrastructure drinking water and wastewater systems. Most states do not collect condition data for these smaller systems, so an accurate assessment of the remaining lifespan or current condition is nearly impossible to determine.

The remainder of the population approximately 20% of Americans rely on onsite wastewater systems such as septic tanks. Reclaimed wastewater frees up fresh water that can be used somewhere else, such as for drinking water. Additionally, utilities grapple with treating and disposing of byproducts containing contaminants of emerging concern such as per- and polyfluoroalkyl substances (PFAS, forever chemicals) or novel biological components (antibiotic-resistant genes). Sewers collect sewage and wastewater from homes, businesses, and industries and deliver it to wastewater treatment facilities before it is discharged to water bodies or land, or reused.
