According to the EPA, the nation’s drinking water utilities need $384.2 billion in infrastructure investments over the next 20 years. Much has been written about the problems associated with aging water infrastructure and less so about solutions. Fortunately, efforts to address these critical issues are underway.
When it comes to the history of aged water and wastewater infrastructure, every building has a story to tell. Such is the case with Louisville Water Company's retired 150-year-old Original Pumping Station No. 1 and water tower in northern Kentucky. In January 2013, the organization launched a year-long project to restore the interior of the station and build a museum commemorating the value of water and history of the premises.
Wastewater treatment lagoons produce high levels of sludge, and many lagoon owners are seeking innovative, sustainable and cost-effective approaches as solutions to eliminating mechanical dredging. On method is biodredging, a biological process that digests sludge in situ and reduces its accumulation at the onset.
Cofferdam and dewatering projects pose a number of complex challenges during construction. As such, Portadam and Rain for Rent have partnered to provide technologically-advanced dewatering solutions for use in construction, remediation, rehabilitation, flood protection, and inspection projects in various waterways and other retaining areas.
Dewatering is essential to the success of many jobsites and is particularly necessary when removing groundwater in order to safely perform certain tasks. Further, every location has its unique dewatering challenges, and it’s crucial to consider all of the factors when designing an effective plan.
One of the more unique measurement landscapes is open channels, where the flow of liquids along a free surface is occasionally "open" to the atmosphere. These can be tough to measure, but careful attention to flow height and flume position can help boost accuracy and verifiability.
Recent technological developments in a number of blue infrastructure technologies have facilitated the maximum use of existing urban infrastructure, bridging the gap between traditional gray infrastructure and evolving green infrastructure.
In September 2013, 14 inches of rain drenched Colorado’s Front Range and put the state’s history of proactive flood control to the test. Nearly six months have passed, allowing for a better perspective on the effects and lessons learned from this extraordinary event.
Here in the United States, when we turn on our taps, we can rest easy knowing that what comes out is safe to drink. This is due in large part to the competence and skill of the men and women certified to treat our water and ensure its quality. But since the first mandatory operator certification program was established in New Jersey in 1918, some 80 more followed - each one different from the next.
As Congress returned to work in January, the fate of Water Infrastructure Finance and Innovation Authority (WIFIA) legislation was still in question. Also, several industry groups have joined forces to reduce the volumes of non-flushable disposable products that collect in wastewater systems.
In order to insure that a pump’s performance matches the system requirements, both the pump and system head/pressure and flow rate performances must meet expectations. With that, factory pump performance is available in several forms, each with varying degrees of accuracy.
As wastewater treatment plants are built, expanded and upgraded, optical fiber is becoming an essential part of the communications infrastructure. These plants rely on the coordination of many moving parts to maintain successful operation, and cable choice is particularly important because of the uniquely harsh environment.
The water and wastewater industry seeks to finds its focus for the New Year with everything from improved water conservation and nutrient removal to enriched infrastructure development and funding and regulation strategies.
The city of Tempe, Ariz., recently completed a water quality upgrade to its 50-million-gallon-per-day water treatment facility that included an overhaul of its dosing systems for sodium hypochlorite (NaOCl) used to disinfect the water.
