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.

Correct defect identification and damage assessment in general and of corrosion defects in particular as basis for efficient sewer rehabilitation planning
ABSTRACTAs waste water systems get older, their performance tends to decline. Breaks, cracks, corrosion and other types of failures causing leakage, hydraulic bottlenecks etc. up to collapsing sewers and mains. Condition assessment – either cyclic or demand orientated – is the basis for rehabilitation planning. The quality of inspection and assessment forms the base for cost efficient and sustainable section and network rehabilitation. Especially corrosion defects are difficult to identify and separate from other defects such as abrasion or incrustation. The correct identification of each of the defects is one major issue for later rehabilitation planning. Another one is the correct assessment of such defects. Sophisticated damage models, based on stability analysis, allow the possibility of detailed section assessment needed for priority ranking and the indication of the rehabilitation type (repair, renovation or replacement). The theoretical background of the different steps is outlined and all issues are dealt with in detail on examples.

Modern methods of installing dependable hydrants
In cases of fire outbreaks, a constant and reliable supply of water must be readily available to enable the fire fighters to complete their allotted task. At the same time the water supply utilities are obliged to take the necessary measures to ensure that a piping network can be effectively filled, vented, flushed and drained as well as to be able to provide temporary or emergency supplies through the use of hydrants. Each and every pipeline component installed up to the hydrant outlet must function in a reliable manner. Other factors such as traffic flow, space requirements and hydrant type must be taken into consideration during the installation of such water hydrants. This paper is intended to give an overview of the products and methods in use today as well as future developments in this direction.
