With so much demand on operating budgets, water and wastewater utility dollars must be spent — or conserved — wisely. Energy expenditure is a prime savings opportunity, but how do you pull it off successfully? Here are some factors, illuminated with a case study, to consider.
In just eight years at DC Water, which provides drinking water, sewage collection, and sewage treatment in Washington, D.C., serving more than 600,000 residents, George Hawkins transformed the utility from insular and guarded to open and innovative.
Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.
Aging infrastructure, including water networks, is an ongoing problem. The American Society of Civil Engineers (ASCE) provides a four-year report card on the state of our infrastructure, and the water sector received a grade of “D” on the 2017 Infrastructure Report Card. Clearly, much work is needed to bring our water systems up to par. But with finances consistently tight, knowing how and where to spend is crucial.
When emergency strikes, water and wastewater utilities can rely on one another through an innovative program.
When federal and state environmental agency mandates required the City of Havre, Montana to upgrade its wastewater treatment facility, utility leaders decided to implement a more efficient record keeping process at the same time. Havre is located in the north central portion of the state and is home to about 10,000 residents. The newly upgraded wastewater treatment facility officially started up in September 2016 with the capacity to treat 1.8 million gallons of sewage per day. Since the upgrade, the facility is now able to address ammonia reduction and comply with total nitrogen/phosphorus limits. Since day one, all of the Havre Wastewater Treatment Facility’s operational data has been tracked in OpWorks, a web-based application.
Any water utility that has to impose restrictions due to water scarcity appreciates the value of conservation. On the other hand, there are utilities that — knowingly or unknowingly — permit as much as 20 to 40 percent of their treated water to trickle away without collecting a cent for it. If you have experienced either extreme, but are not already using advanced metering infrastructure (AMI), what’s holding you back? Before dismissing AMI as being too costly, too technical, or too difficult to implement, consider the following cost-benefit opportunities.
According to the EPA, the volume of treated water lost annually through distribution systems is 1.7 trillion gallons at a national cost of $2.6 billion. Advanced metering infrastructure (AMI) is one way to uncover the “hidden” details behind that assault on water distribution efficiency. In addition, innovative use of AMI smart water solutions also creates cost-efficient ways to optimize performance beyond recouping losses due to leaks, theft, or incomplete billing.
Water conservation has long been a hot topic between water utilities and their end users for a variety of reasons — seasonal water scarcity, overextended treatment facilities, periodic maintenance disruptions, etc. But when it comes to managing data that can help control water losses and recover billings for non-revenue water (NRW), why is it so hard to practice what we preach? This article dispels some of the common myths related to advanced metering infrastructure (AMI) technology that can help cut treated water losses and generate previously overlooked revenue.
Despite their best intentions, wastewater operations all over the country have suffered from accidently under- or over-administering treatment chemicals when trying to get effluent into shape. With the proper tools, however, these mistakes can become a thing of the past.
Irish Water, in partnership with Leitrim County Council, today (Friday) turned the sod to mark the start of upgrade works on the Manorhamilton and Mohill Wastewater Treatment Plants, as part of a €3.5M investment by national utility.
The American Water Works Association recently urged the U.S. Environmental Protection Agency to revise its regulation on lead in water to advance the removal of lead service lines while assuring that water systems adjust water chemistry to control corrosion and inform customers about lead risks.
Utah State University's (USU) Buried Structures Laboratory has published a second comprehensive study on break rates of the most commonly used water pipe materials titled, "Water Main Break Rates In the USA and Canada: A Comprehensive Study."
Jerusalem water corporation Hagihon has extended its agreement with TaKaDu, a global leader in Integrated Event Management solutions, for another three years.
The U.S. Department of the Interior recently released a report highlighting the progress made in the fight against invasive zebra and quagga mussels, which can impair the delivery of water and power, diminish boating and fishing, and devastate ecosystem health.
ACCIONA Agua, in consortium with BTD, has been chosen by the Loja municipality, with funding from the Andean Development Corporation (CAF), to build a wastewater treatment plant in Loja (Ecuador) under a turnkey contract worth 16.6 million dollars (about 13.4 million euro).
Wastewater systems are integral to infrastructure in every community. In an ideal world, they operate smoothly and are long-lasting. But biogenic transformation processes in sewage and water treatment systems are a “natural enemy” of conventional plants, frequently causing damage to concrete and metal elements that is expensive to repair.
Working in partnership with Irish Water, Veolia, the global resource management company has commenced work on an €80M and 400,000 population equivalent upgrade to the Ringsend Wastewater Treatment Plant.
“If Trenton has failed to meet critical deadlines in the past, why does the state think that will change in the future? In a head-scratching move, the New Jersey Department of Environmental Protection (DEP) entered into a contract with the city, allowing for an extension for Trenton to fix its constant and growing issues at Trenton Water Works (TWW),” The Trentonian reported, calling the utility “dysfunctional.”
Archer Western Construction, LLC and joint venture partner Brown and Caldwell were awarded the Progressive Design-Build project at Fulton County’s Big Creek Water Reclamation Facility in Roswell, Ga.
