What is the difference between a combined sewer system and a sanitary sewer system?
Sanitary sewer systems carry only domestic and industrial wastewater, while combined sewer systems also carry stormwater runoff.
How is wastewater treated?
Wastewater is typically treated through a series of five major steps followed by processes to reuse or to dispose of the remaining products. This treatment requires an intricate balance of physical, biological, and chemical processes. They include:
What is the function of a wastewater treatment plant?
The function of a wastewater treatment plant is to speed up the process by which water is cleaned naturally. Treatment plants are operated by a treatment team that is committed to protecting public health and the environment.
What is secondary treatment?
Secondary Treatment is designed to grow naturally occurring microorganisms to digest organic material, sometimes remove nutrients, and then to settle to the bottom of a secondary sedimentation basin.
What are some alternatives to disinfection?
Alternatives for disinfection include chlorination followed by dechlorination, exposure to ultraviolet light, and the infusion of ozone. Solids Handling involves the treatment of the solids removed from the water treatment processes to be made acceptable for landfills.
How many wastewater treatment plants are there in the US?
There are more than 16,000 publicly owned wastewater treatment systems of various sizes serving the majority of wastewater needs in the United States. The remainder of the population — approximately 20% of Americans — rely on onsite wastewater systems such as septic tanks. Although the nation’s population growth projections are modest, a 2018 Pew Research Center study expects 86% of this growth to occur in urban and suburban areas. Growing urban environments signal a trend that centralized wastewater treatment plants (WWTP) will increasingly accommodate a larger portion of the nation’s wastewater demand. Currently, 62.5 billion gallons of wastewater per day is being treated by centralized WWTPs. Across all sizes of WWTPs, systems are operating at an average of 81% of their design capacity, while 15% of systems are at or have exceeded that threshold.
How long do WWTPs last?
The majority of the nation’s WWTPs are designed with an average lifespan of 40 to 50 years, so the systems that were constructed in the 1970s, around the passing of the Clean Water Act in 1972, are reaching the end of their service lives.
How long do septic tanks last?
However, smaller onsite systems, such as septic tanks, have a shorter average lifespan of 20 to 30 years. 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.
How long does a wastewater system last?
The typical lifespan expected for wastewater pipes is 50 to 100 years. As collection systems age and decline in condition, groundwater and stormwater enter the networks through cracks, joints, or illicit connections as inflow and infiltration.
Why should infrastructure owners engage in asset management practices across infrastructure sectors?
Infrastructure owners should engage in asset management practices across infrastructure sectors to extend the lifespan of assets and prioritize limited funding. Asset management must include continuous assessment of the condition of assets and prioritize investment decisions based upon a comprehensive suite of data.
What is wastewater infrastructure?
Wastewater infrastructure includes a network of sewer pipes that collect and carry household, business, and industrial effluents to wastewater treatment systems — onsite or centralized facilities. Within these treatment systems, wastewater undergoes processes to remove harmful constituents and reduce pollution to the Environmental Protection Agency (EPA) and/or state-regulated levels prior to being discharged into nearby waterbodies or, in some cases, recovered for water, energy, and nutrient reuse.
How many public wastewater systems are there in the US?
There are more than 16,000 publicly owned wastewater treatment systems of various sizes serving the majority of wastewater needs in the United States. The remainder of the population — approximately 20% of Americans — rely on onsite wastewater systems such as septic tanks.
How to become a certified water operator?

What is the DEP Act?
The Water and Wastewater Systems Operators Certification Act (Act) grants DEP with the ability to petition the State Board for Certification of Water and Wastewater Systems Operators (Board) to revoke, suspend, or modify the certification of water and wastewater system operators based on operator misconduct. Operator misconduct includes, but is not limited to, falsification of certification application, certificates, sample results, monitoring records, or other records relating to the operation of a water and wastewater system. The Act grants the Board with the authority to revoke, suspend, or modify an operator's certificate based on the operator's misconduct.
How often do you need to do an external certification review?
The U.S. Environmental Protection Agency requires all states to complete an external review of their Operator Certification Program at least once every five years. External program reviews provide the state with a report describing the results of the review and listing recommendations for improving the program.
What is a second degree misdemeanor in Pennsylvania?

What is considered a significant discharger?
Only one facility in DC is considered a significant discharger: Blue Plains, the largest wastewater treatment plant in the Chesapeake Bay region and one of the largest and most advanced plants in the U.S. The plant treats wastewater from DC, MD, and VA and is allowed to trade nutrient credits in Virginia’s trading program. According to its discharge monitoring data, Blue Plains did not discharge more nitrogen or phosphorus than its permit allowed in 2016, and it is already meeting its bay cleanup goals for 2025.
How many sewage plants in Virginia have violated their permit limits?
Across the Chesapeake Bay watershed, 21 sewage treatment plants violated their permit limits last year by releasing excessive amounts of nitrogen or phosphorus pollution that fuel algal blooms and low-oxygen “dead zones” in waterways, according to an Environmental Integrity Project examination of federal and state records.1 The plants in violation included 12 municipal sewage facilities in Maryland that treat more than half of the state’s wastewater, with the most pollution coming from the state’s largest two facilities: Baltimore’s Back River and Patapsco wastewater treatment plants. In West Virginia, six wastewater plants violated their permit limits in 2016; in Pennsylvania, two did; and in New York, one. In both Virginia and Pennsylvania, pollution credit trading systems allowed many plants that were over their limits to buy their way out of violations. The credit swaps in these Wall-Street style schemes reduce transparency and accountability and contribute to local pollution “hot spots” – for example, in Virginia’s Shenandoah Valley, where the waters are overloaded with phosphorus and algal blooms.2
Where is the Salisbury wastewater treatment plant?
The Salisbury Wastewater Treatment Plant, in Wicomico County on the Eastern Shore, has the capacity to treat about seven million gallons of wastewater a day (including about a million gallons daily from a local Perdue Farms poultry processing plant).
Is Maryland upgrading its sewage system?
Modernizing sewage treatment plants has proven over the last half century to be the most successful method of improving local water quality and the Chesapeake Bay. But the regional states have not invested equally in upgrading wastewater plants. Maryland has done more than many states – especially Pennsylvania, New York and Delaware – to upgrade its sewage
Does Pennsylvania allow pollution trading?
Like Virginia, Pennsylvania allows pollution trading, with regulations in place since 2010. Plants that exceed their individual permit limits can do so legally by buying pollution credits. The annual pollution discharge amounts (pollution “loads”) shown in the charts below are net loads, which represent pollution totals that have been mathematically reduced to account for nutrient trades and offsets. The actual pollution releases (gross loads) are higher when trading occurs. For the wastewater facilities that do not trade or rely on offsets, the net and gross loads would be the same. However, the data reported in the EPA online enforcement database show that facilities sometimes fail to account for trading in their discharge monitoring reports, with the result that reported gross and net annual discharges are the same. This makes it difficult to determine if facilties are in compliance with their discharge permits and reduces transparency.
Does New York have a nitrogen pollution trading program?
Only one wastewater facility in New York’s share of the bay watershed exceeded its annual permit limit for phosphorus last year, and none exceeded its permit limits for nitrogen. New York does not have a pollution trading program, per se. But the state does allow wastewater facilities to “offset” their own excess nitrogen discharges for if they discharge less phosphorus pollution. One facility, Bath Wastewater Treatment Plant in Bath, NY, discharged 64,038 pounds of nitrogen to the Cohocton River with a permitted annual limit of 61,000 pounds. However, the facility was able to mathematically offset its nitrogen discharge to 57,133 pounds by discharging less phosphorus, bringing it into compliance with its permit limit. But, this facility still has to reduce its nitrogen discharges significantly if it is to meet its 29,941-pound 2025 bay cleanup goal.
Does West Virginia have a pollution trading system?
West Virginia, like Maryland, does not use pollution trading for the regulation of its wastewater treatment plants. Three wastewater plants in Virginia’s portion of the Chesapeake Bay watershed exceeded their permit limits for nitrogen in 2016, and six facilities exceeded their limits for phosphorus pollution, according to EPA data (six total, as some exceeded limits for both pollutants.) The facilities listed in tables 10 and 11 below have all entered into legal agreements with West Virginia Department of Environmental Protection (WVDEP) concerning violations of their nitrogen and phosphorus permit limits. For example, the Petersburg Wastewater Treatment Plant entered into a consent order with WVDEP on June 15, 2016, that required the city to undergo a $7.2 million upgrade its sewage plant,41 but it did not waive compliance deadlines with the facility’s annual permit limits for total nitrogen or total phosphorus.42 The upgrades are expected to be complete by early 2018.
