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).

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.
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.
The impact of this tech domestically is substantial, but the real excitement is in the developing world, where wastewater treatment plants tend to be far and few between and electricity is seriously in need.

In some places, current technology for small, compact wastewater treatment plants has improved, offering advantages over larger, centralized systems.
The sustainable living project is considerably less esoteric: a wastewater treatment plant built with the very latest in green technologies and construction techniques.
It aims to establish a platform for exchange of knowledge with respect to methods for characterisation of colloidal and particulate matter in these systems and to cover the technological aspects of particulate matter in different water treatment processes such as drinking water, wastewater and landfill polluted waters.
The firm has made investments in small companies like Aquarius Technologies, a Wisconsin-based wastewater treatment firm.

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.
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.
