In some places, current technology for small, compact wastewater treatment plants has improved, offering advantages over larger, centralized systems.
Many cities in the Northeast and Great Lakes region collect storm water to clean it in wastewater treatment centers.
Well, we generate about 8 million tons of sludge annually (this accounts for 30-80 % total electricity in wastewater treatment).

The sustainable living project is considerably less esoteric: a wastewater treatment plant built with the very latest in green technologies and construction techniques.
He decided to upgrade a proposed wastewater treatment plant for Omega into a grander project that could have an impact far beyond the Rhinebeck campus.
That trend will also increase pressure on wastewater treatment and disposal.
For decades, discharges by wastewater treatment plants and land runoff have led to excessive levels of nutrients such as nitrogen and phosphorus in Long Island Sound.
The EPA wants to monitor municipal wastewater treatment plants that receive certain types of silicones to assess whether they cause any harm to the environment.

"It signals to us that the source (of the caffeine) really isn't the high population centers, possibly because they are on wastewater treatment plants, " Granek told CNN.
For the vast Marcellus shale, the issue is whether the state's wastewater treatment facilities are adequate and can keep up with the pace of expansion in shale drilling.
WSJ: Daniel Yergin on the Shale Gas Revolution: Stepping on the Gas
The city's storm-damaged wastewater treatment plant is still undergoing repairs.
The findings indicate that wastewater treatment plants are effective at removing caffeine from the water, but that high rainfall and combined sewer overflows flush the caffeine out to sea.
The winner in that category: Pasteurization Technology Group, a San Leandro, Calif. startup that treats wastewater using an energy-efficient process that recycles the methane produced by wastewater treatment.
Three main topics will be tackled, namely removal of particulate and colloidal matter within drinking water production and in wastewater treatment, and reduction of colloidal carriers mobilised from waste disposals.
What emerged was a wish list from customers that included cleaner ways to burn coal and more efficient wastewater treatment systems, as well as nuclear power and hydrogen fuel cells.
In fact, based on your own reporting, the industry has increased their recycling threefold over the last 18 months alone, significantly lessening the burden for further wastewater treatment and disposal.

Using so-called anaerobic digestion, ExoGen aims to make wastewater treatment for industry and agriculture much more efficient by creating a significant amount of energy throwing off electrons and methane gas during the treatment process that partially offsets the energy required to treat the wastewater.
FORBES: Will Cambrian Innovation Revolutionize Waste Water Treatment?
After taking samples from 21 spots along the coast, researchers expected to find the most caffeine pollution in areas near wastewater treatment plants, large population centers or rivers and streams emptying into the ocean, said Elise Granek, assistant professor of Environmental Science and Management at Portland State.
"If this technology works on a commercial scale the way we believe it will, the treatment of wastewater could be a huge energy producer, not a huge energy cost, " said Hong Liu, an associate professor in the OSU Department of Biological and Ecological Engineering.
Without these things, we would not have clean, drinkable water, or the ability to convey wastewater away from our homes to treatment facilities, or systems to handle the vast amounts of garbage we produce, or anything to drive on to accommodate our four-wheel lifestyles.
FORBES: 2012 is the Year America Must Get Serious About its Infrastructure
As a result, some wastewater associated with shale gas is transported to treatment plants that are not properly equipped, the agency adds.
Today, Harrisburg is struggling to upgrade other critical infrastructure, including a sewage treatment facility that sometimes dumps untreated wastewater into the Susquehanna river.
While this concern is certainly legitimate, the more immediate concern has been the treatment of millions of gallons of fracking wastewater.
Another method, used mainly in Pennsylvania, is to simply use treatment facilities to clean up the fracking wastewater before it heads into local rivers and streams.
