National Urban Renewal Mission
"Today, a third of our population lives in urban areas and keeping in mind the speed at which urbanisation is taking place, the day is not far off when over 50 percent of India's population will be residing in urban areas. We taught the world the basic concepts of urban planning. But today our cities are often unable to meet the basic needs of their residents on many counts."

Demonstration of pipe and pipeline integrity by means of intelligent pigging systems
The service life of all man-made "technical products" is limited. Piping and pipelines are no exception. For technical installations such as pipelines, availability of which is critical for global economy, strength analyses and service life calculations must be prepared to furnish evidence of pipeline integrity and strength. The aim of these analyses and calculations is, despite ongoing operational loads, to prevent impermissible stresses from acting on pressurized parts and possibly resulting in critical conditions. The increasing use of thin-walled pipes made of high-strength steel further adds to the necessity of inspecting pipe walls for direct and indirect defects. Direct defects are those which impact on pipeline safety and integrity and are generally detected by inspection pigs (pipeline inspection gauges).

Detection of coating defects in pipelines using in-line inspection tools
The following article investigates the current possibilities for the in-line inspection of pipeline coating. Due to its different accessibility internal coating should be distinguished from external coating. With the existing methods of in-line inspection some information on the condition of specific types of coating can be obtained. It is discussed which current inspection methods are able to deliver and how minor changes would improve the value of the information. For in-line inspection tools internal coating is easier to detect than external coating. Sample measurements are presented for testing of internal and external coating using intelligent ultrasonic inspection tools.

Cleaning of industrial pipes - Chemical pipe rehabilitation
In pipelines in industries formation of deposits occurs frequently. These deposits prevent the transport of substances and need to be removed on a regular basis to ensure smooth operation. Many a times, aggregates are installed such as heat exchangers, cooling tower or chill rolls, mastication rollers, injection moulding machines, bioreactors etc., and they have to function smoothly, because production depends directly on them. There are different processes for cleaning pipes, which include mechanical processes such as high-pressure cleaning, scrapper cleaning or milling, or alternatively chemical and chemo-mechanical processes respectively.

WEF, APWA talk water and wastewater infrastructure funding with Congress
Humans, who can last a month without food, die after a week without water. And while we rely on water to sustain life, many are not aware of the vast network of reservoirs, plants and pipes required to treat, distribute, collect and clean water. Much of the nation's water infrastructure, built nearly a century ago for a smaller population, is aging and overburdened.

Prototype software helps predict failure in large-diameter water mains
Occurrences of failure in large-diameter water mains are few and far between, but when these buried pipes do fail, they fail in a big way. The consequences can be catastrophic, including prolonged service disruptions, flooding, major traffic and business disruptions, and contaminated water supplies. The cost of repair is also enormous.
