• Harnessing The Power Of GIS To Improve Customer Service

  The COVID-19 pandemic has rewritten the way businesses and organizations operate and serve their customers, and utility districts are no exception. White House Utility District (WHUD), Tennessee's largest water and wastewater provider in terms of geographic area served, is a case in point.

• Troubleshooting Nitrification And Denitrification In Wastewater

  The proper tools are essential to fixing any problem. Over the years, Ohio EPA’s Compliance Assistance Unit (CAU) has helped dozens of water resource recovery facilities (WRRF) get back into and maintain compliance with NPDES discharge permits. Their field toolkit has included an assortment of batch sampling kits and handheld instruments. Each tool had its place but each also had limitations and, as a result, the compliance puzzle often was missing important pieces. Increasingly, as nutrient limits were incorporated into discharge permits, the missing piece was characterizing the dynamics of nitrification and denitrification. By Patrick Higgins

• Transforming Cities And Infrastructure For A Sustainable Future

  This paper discusses how the right combination of digital tools is helping cities move from a reactive response to delivering a more sustainable future while saving costs and connecting the workforce to trusted data.

• Top 10 Technologies From WEFTEC

  They did it again. Seemingly every year WEFTEC breaks records for size and attendance, and 2014 in New Orleans was no exception. There was a lot to choose from, but I picked my favorite innovations to highlight in what has become another annual tradition — Water Online’s “Top 10” from WEFTEC.

• Building An Enterprise GIS To Support Efficiency Across The Organization

  Padre Dam Municipal Water District provides water, wastewater, recycled water, and park and recreation services to over 102,000 residents in East San Diego County in California. Padre Dam's infrastructure is worth over $700 million, and it has an annual budget of $76.3 million. Padre Dam imports 100 percent of its drinking water supply and treats two million gallons per day (MGD) of wastewater at the Ray Stoyer Water Recycling Facility.

• City Of Henderson, NV Tackles Predicted Water Demand Increase Through Master Plan Optimization Saving $120M Over Traditional Design

  The City of Henderson engaged Stantec and Optimatics to develop a new master plan for their water distribution system, in preparation for the expected population growth and demand increase in the coming years. This optimization effort aimed to determine the lowest cost master plan strategy that satisfied the City’s hydraulic design standards, based on forecast 2050 demands Prior to optimization, the City and Stantec had identified a range of possible project sites, so the optimization was largely focused on determining which of these projects to complete, as well as how to size them.
