What is the difference between water treatment and wastewater treatment?
Water treatment is done to water before it is sent to a community, while wastewater treatment is done to water that has been used by the community. Water treatment has higher standards for pollution control because it is assumed that any drop of distributed water could be consumed by a person.
What happens to poop at the water treatment plant?

The Milwaukee Metropolitan Sewerage District (MMSD) cleans billions of gallons of wastewater every year, safeguarding natural resources and protecting public health for 28 communities in southeastern Wisconsin.
MMSD Renewable Energy
Sustainability is a rich part of MMSD's history, integral to present-day operations, and critical to our future. However, cleaning water is very energy-intensive. Therefore, MMSD utilizes renewable energy to reduce energy costs, price volatility, greenhouse gases and provides energy security.
What is public involvement in sewer planning?
Public involvement is an important aspect of any planning effort for a new or significantly modified sewerage system. Municipalities must conduct at least one public hearing as required by s. NR 110.09 (4), Wis. Adm. Code. A copy of the facility plan report should be available for public review before the hearing and at the hearing. Exceptions to the public hearing requirement may be provided if the proposal is for a minor upgrade or if it is a revision to a previously approved project subject to a previous public hearing. Prior to issuing a facility plan approval letter, the Department will issue a news release and typically allow a two-week time period for public comments.

What is NR 110 in Wisconsin?
Chapter NR 110 is applicable to all sewerage systems except systems treating industrial wastewater or "private sewage systems" regulated by the Department of Commerce. This guidance is not applicable to limit questions arising from routine Wisconsin Pollutant Discharge Elimination System (WPDES) permit reissuance or to requests for alternative phosphorus limits.
What happens after a facility plan is approved?
After a facility plan report receives Department approval, there are typically minor design refinements or project changes that occur as the final construction plans and specifications are developed. Minor changes from approved facility plan recommendations should be identified and justified as part of the construction plan and specification review. If the changes are significant, it may be necessary for the sewerage system owner to prepare and submit a facility plan amendment report to the Department for review under the s. NR 110.09 facility planning rules. The review of an amendment may include a requirement for an additional public hearing. Changes that are normally considered "significant" would involve proposed use of a new site, significant changes to project cost estimates, significant changes to effluent limits or other design parameters or the discovery of potential environmental impacts not previously identified.

Monitoring wastewater is used for early detection of COVID-19 within a community. For people with COVID-19, the virus can be detected in their feces shortly after they are infected with the virus, even before they experience symptoms or if they are infected but asymptomatic.
How does wastewater monitoring work?
Wastewater samples are analyzed by the Wisconsin State Lab of Hygiene and University of Wisconsin-Milwaukee to determine the amount of SARS-CoV-2 virus (the virus that causes COVID-19) present. The amount of virus, measured as viral gene copies, can indicate if COVID-19 is increasing or decreasing in a community.

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 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.
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 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.
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.
What is the rule similar to the Water Infrastructure Act of 2020?
