With the need for clean water, the average water requirement is 93.27 liters/second to 130.41 liters/second

Local Land Use: Decision Expands Federal Government\u27s Role

The United States Environmental Protection Agency (EPA), pursuant to its authority under the Clean Water Act, has promulgated regulations creating the Storm Water Management Program. Contrary to the overall Clean Water Act scheme, which focuses on reducing pollution from point sources, the program has the objective of reducing non-point source water pollution. However, this program is not without controversy as heavy burdens are placed upon local governments, who themselves lack the financial resources, manpower, or technology to implement a complex federal system without federal or state assistance

The Economic Argument for Cleaning Up the Chesapeake Bay and its Rivers

Failure to "Save the Bay" threatens the Bay's value as an economic driver. Conversely, investing in clean-water technology creates jobs, generates economic activity, and saves money in the long run. Hence, the protection and restoration of the Chesapeake is essential for a healthy and vibrant regional economy. This CBF report takes a close look at the relationship between clean water and the Bay region's local economies

PERENCANAAN JARINGAN AIR BERSIH PEDESAAN (Studi Kasus di Desa Bulukerto Kecamatan Bumiaji Kota Batu)

As the number of residents and housing in an area increases, the need for clean water consumption will continue to increase from year to year, therefore the system or facilities needed to provide clean water that currently exist will not be possible in the future. serve the needs of water according to the demand of the community needed. With the increasing need for clean water consumption in Bulukerto Village, it is necessary to evaluate and develop the clean water distribution network so that the community's need for clean water can be met. The method chosen for population projections in 2031 is the arithmetic method, and for planning clean water networks using the Waternet program. Network development by adding 2 pumps and 2 new tanks to meet clean water needs in 2032. Initial investment cost is IDR. 984,675,784. With a selling price of Rp. 500/m3 and it is assumed that an increase of Rp. 750/m3 in the 6th year obtained an NPV value of IDR 316,198,855 ˃ 1 (declared feasible) with a BCR value of 1.03 ˃ 1 (declared feasible), PBP 5.72 Years < 10 Years (declared feasible) and IRR 15.98% ˃ 10% (declared eligible)

Fearless: Mike Altman

After participating in the 2011 Heston Internship in Uganda working in a community on clean water projects, Mike gained a new interest in Global Health. His interest grew and a few months ago he started an internship with charity: water, an organization working to bring access to clean water throughout the world in a way that attempts to break the traditional donation model. At charity: water, Mike is part of a greater group that is working to more closely connect people to specific water projects through financial transparency and innovative fundraising campaigns.

The \u27Ascent of Man\u27: Legal Systems and the Discovery of an Environmental Ethic

A decade ago, firefighters in a warehouse on the Rhine in Switzerland washed chemicals, solvents, and mercury into the river, destroying all life in the river for miles, killing millions of fish, and endangering the water supplies of cities in Germany and the Netherlands. This tragedy galvanized the river valley states into action. They vowed to clean up the river, not just from that incident but from the effects of having used the river as a sewer for two centuries. But how clean is clean? The goal for this calculated plan, which will take decades to achieve, is symbolized by the salmon. When salmon spawn again in the Rhine, then it will have been restored. Will these nations succeed? If the twenty five year history of our Clean Water Act offers a precedent, “restoring and maintaining” the waters of the United States for fish and swimming, the prognosis may be good

The Economic Benefits of Cleaning Up the Chesapeake

Information on the economic benefits of environmental improvement is an important consideration for anyone (firms, organizations, government agencies, and individuals) concerned about the cost-effectiveness of changes in management designed to achieve that improvement. In the case of the Chesapeake Bay TMDL (Total Maximum Daily Load of nitrogen, phosphorus, and sediment), these benefits would accrue due to improvements in the health, and therefore productivity, of land and water in the watershed. These productivity changes occur both due to the outcomes of the TMDL and state implementation plans, also known as a "Chesapeake Clean Water Blueprint" itself (i.e., cleaner water in the Bay) as well as a result of the measures taken to achieve those outcomes that have their own beneficial side effects. All such changes are then translated into dollar values for various ecosystem services, including water supply, food production, recreation, aesthetics, and others. By these measures, the total economic benefit of the Chesapeake Clean Water Blueprint is estimated at $22.5 billion per year (in 2013 dollars), as measured as the improvement over current conditions, or at$28.2 billion per year (in 2013 dollars), as measured as the difference between the Clean Water Blueprint and a business-as-usual scenario. (Due to lag times—it takes some time for changes in land management to result in improvements in water quality, the full measure of these benefits would begin to accrue sometime after full implementation of the Blueprint.) These considerable benefits should be considered alongside the costs and other economic aspects of implementing the Chesapeake Clean Water Blueprint

Portable seawater desalination tank

As a result of the hot and dry weather caused by the El Nino phenomenon or the overheating weather that struck our country, water supply dams and rivers supplying raw water resources for water treatment plants in all state were declined (Termizi, 2017). Among the causes of clean water shortage is the pollution due to the poor waste management without systematic method, causing pollution and contamination to the water sources. In the meantime, many countries have also presented some issues with less favourable facilities, especially the problem cause by the lack of clean water at the coastal area (Hirschman, 1975). Thus, portable seawater desalination was developed using condensation concept and distillation methods to produce clean water sources for coastal visitors as well as the use of local residents as an alternative to the dry season
