Solutions for Aging Water Infrastructure

The pipelines that municipalities use to deliver drinking water to their residents take a beating. Large cities pump tens of millions of gallons of water to their customers every day. And many of the pipes that municipalities rely on to transport drinking water and treat wastewater are coated with decadesworth of grime and pollutants.

It’s little surprise then, that a growing number of municipalities face a problem: Their aging pipes are so filled with sludge and biofilm that it is reducing the speed at which they can pump water. This means that pumps have to work harder in these systems, increasing the energy costs and the expenses that these cities face when providing drinking water to residents and commercial buildings.

Air Quality Management – Wiley

I remember when I had done a natural sciences course, how dire the outlook, in terms of, water resources and the environmental sustainability looked. I am sure that if many of my classmates hadn’t thought about the environment and its relation to their survival and that of the next generation, it definitely would have been thought of then and afterwards.

At the Wiley Online Library I came across a text entitled “Air Quality Management” (March, 2014), which is one of four texts to assist readers in developing Environmental Impact Assessments (EIAs).

This document offers one an introduction to the atmosphere around us and the units of concentration. It also discusses the importance of meteorology and the part it plays in air quality, before detailing the main types of air pollutants, their sources, and their effects on humans and their environments. Further chapters discuss measurement technologies and systems, as well as a selection of control and elimination methods. The book also details methods of modelling atmospheric dispersion.
