Direct potable reuse: a future imperative
As a result of population growth, urbanization, and climate change, public water supplies are becoming stressed, and the chances of tapping new water supplies for metropolitan areas are getting more difficult, if not impossible. As a consequence, existing water supplies must go further. One way to achieve this objective is by increased water reuse, particularly in supplementing municipal water ...

An Overview of Solids Handling
The purpose of wastewater treatment plants is to remove impurities and produce water that can safely return to the water supply. In manufacturing plants, this process involves treating water to remove harmful chemicals. The wastewater plant must remove any solid matter flushed into the system for a municipal water supply. Solids handling is the process that takes these materials and generates a ...

Municipal water pricing and tariff design: a reform agenda for South Asia
The water tariffs currently in use in most cities in South Asia are not accomplishing their principal objectives. They are not generating sufficient revenues to ensure that utilities can recover their financial costs. They are not sending the correct economic signals to households, i.e., that water is scarce and must be treated as a valuable commodity. They are not helping the majority of the ...

Water reclamation and intersectoral water transfer between agriculture and cities – a FAO economic wastewater study
Cost–benefit studies on replacing conventional agricultural water resources with reclaimed water in favour of cities are still rare. Some results of a study under auspices of the Food and Agriculture Organisation (FAO) are presented. By means of an illustrative example at Lobregat River basin in Spain, it could be proved that reclaimed water reuse and intersectoral water transfer can result in ...

Membranes: TOC reduction using membrane technology
Honeywell’s Solid State Electronics Centre (SSEC) in Plymouth, Minn., had been trying to reduce the level of total organic carbon (100) in its high-purity deionized water system for many years. They had always experienced periods of relatively low 100 (less than 10 parts-perbillion [ppb]) but always had periods of high 100 (greater than 50 ppb). These high periods had usually been short periods ...

Efficiency evaluation of urban water supply services in an Indian state
Water supply services in urban India are essential functions of urban local bodies or municipalities. These services are mostly perceived as unsatisfactory across urban centres and the sector is widely perceived to be misgoverned with large number of municipalities making financial losses. However, this common perception of inefficient services has not much scientific basis as the efficiencies ...

The story of Chicago`s water tanks after the raging fire of 1871
Now they are rare, but once the water tanks on the roof were the sentry on top of every large building in the city, protecting them from the threat of fire. The purpose of these tanks was to provide a reliable and easily accessible water supply for putting out fires. The water in the tanks is fed by gravity firefighters, so it is almost a safe reserve for emergencies. After the great fire of ...

Developing a Culture of “Revulsion”: Singapore Tackles Water Wastage
Singapore is an interesting place. As a city-state it occupies a very small amount of land area, about 700 square kilometers. Packed into this space are 5.6 million people working in one of the world’s strongest economies. A big part of the economy is based on manufacturing and oil refining. Both of these sectors are intensive water users. Because of this, water availability is a big issue. ...
