•  It’s Good to Be Blue
  Jerry Yudelson, PE
  The water industry recently has seen considerable innovations in freshwater supply, water conservation, and water reuse technologies due to the concern for saving potable, or “blue,” water. Large companies are looking at their global water footprints to see how they can reduce water consumption; thus, water technology has become a major new investment opportunity. How can plumbing engineers get involved? This article discusses some of these new technologies to urban water conservation and efficiency, including desalination, membrane technology, storm water management and treatment, water-quality monitoring, on-site wastewater reclamation, disinfection of water, irrigation automation, and cooling tower water-use efficiency.
• Residential Fire Sprinklers: Why? What? Who? How? and How Much?
  Richard J. Prospal, FASSE, IPP, LMP
  While numerous industry articles about residential fire sprinklers have provided information on how to install these systems, this article takes a different approach and talks about the history of residential fire sprinklers and answers some of those difficult questions: Why install residential fire sprinkler systems? What types of systems are available? Who can install them? How are they designed? How much do they cost? It also debunks some of the myths that are being spread around about residential fire sprinkler systems.
• Domestic Water 101
  Raymond F. Parham, PE
  One of the fundamental design elements that every plumbing engineer faces is the design of domestic water systems, so this article outlines a methodology plumbing engineers can use to design an efficient domestic water system. To do so, it walks through the design process for a relatively large, multistory building, which will allow readers to look at all elements of the design of a domestic water system, including gathering preliminary information, determining whether a water booster pump is needed, locating water heaters, and sizing and laying out the piping distribution network.
