  • Cost analysis of the implementation of portable handwashing and drinking water stations in rural Kenyan health facilities

    Many health care facilities (HCFs) in developing countries lack adequate infrastructure for handwashing and drinking water, increasing the risk of healthcare-associated infections. Attaining permanent, 24-hour/day piped water access – the long-term goal – is time-consuming and expensive. To address this problem in the short- to medium-term, low-cost portable handwashing water stations (HWSs) ...

  • Questions You Should Be Asking Before Renting A Wastewater Tank

    When businesses are in need of a wastewater tank or frac tank, many often purchase their own. However, a wastewater tank can collect dust if it’s going unused between company projects. As a result, the purchasing of a wastewater tank may very well feel like a waste of money. Often times it is. Instead of purchasing a wastewater tank, or another kind of tank, such as bolted steel tanks or an ...

  • Forming DMAs in a water distribution network considering the operating pressure and the chlorine residual concentration as the design parameters

    Dividing a water distribution network (WDN) in the optimal district metered areas (DMAs) formation is one task that usually troubles water utility managers. The present paper utilizes optimization methods to achieve desired segmentation conditions in terms of (a) operating pressure reduction, thus reducing the system's real water losses and (b) residual chlorine concentration reduction thus ...

  • Optimizing DMAs' formation in a water pipe network: the water aging and the operating pressure factors

    Dividing a water distribution network (WDN) into district metered areas (DMAs) is the first vital step towards pressure management and real losses reduction. However, other factors of water quality such as the water age must be taken into account while forming DMAs. The current study uses genetic algorithm (GA) optimization methods to achieve the desired WDN segmentation conditions in terms ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...

  • Experimental characterization of PVC-O pipes for transient modeling

    The increasing use of plastic materials has modified several aspects of design and management of water distribution systems. With reference to the numerical modeling of transients, the definition of a correct rheological model of the pipe material is receiving an increasing interest. In this paper the behavior of the molecularly oriented polyvinyl chloride (PVC-O) pipes during transients is ...

  • Emission of hydrogen sulfide (H2S) at a waterfall in a sewer: study of main factors affecting H2S emission and modeling approaches

    Hydrogen sulfide (H2S) represents one of the main odorant gases emitted from sewer networks. A mathematical model can be a fast and low-cost tool for estimating its emission. This study investigates two approaches to modeling H2S gas transfer at a waterfall in a discharge manhole. The first approach is based on an adaptation of oxygen models for H2S emission at a waterfall and ...
