NEW - Resilient Wastewater and Pumping Tanks (1.5 hrs)

Resilient Wastewater and Evaluation of Pump Tanks
These sessions were recorded at the 2021 NOWRA Mega-Conference

OverviewPresentation #1: Our nation’s aging infrastructure is a common theme in the news. We hear about deteriorating roads, high-risk dams, and old and undersized treatment plants. Wastewater infrastructure is critical to society’s daily functions, health, and safety, yet it is one of the lowest-rated aspects of our country’s framework. Improving wastewater infrastructure involves billions of dollars of repair, rehabilitation, and new construction work. A key to long-term success is to select quality and resilient construction solutions. During this session we will investigate what resilience is and why resilient construction has become a focal point in both centralized and decentralized wastewater projects across the country. We will discuss what factors contribute to resilience and how resilient construction is changing the way wastewater solutions are developed. We will also investigate how resilient decentralized wastewater solutions can improve safety, reduce construction time, reduce costs, and extend service life.

Presentation #2: Pump tanks are used in most secondary treatment systems to collect the treated water and then distribute reuse water into the landscaping around a facility. The pump tank can provide critical information facilitating communication about system performance. Operation and maintenance professionals can use the information gained through evaluating the data gained from these components to inform the customer about the need to perform maintenance activities. Evaluation of pump tanks provides valuable information on the system performance. The water quality in a pump tank following secondary treatment components can indicate to the customer that solids need to be removed from the system. Hydraulic and organic overloading of the treatment system can result in material accumulation in the pump tank. Operational data collected from cycle event counters and elapsed time meters and associated pump performance data can present information regarding the average daily water usage. Comparing the data from the cycle event counter and the elapsed time meter can communicate the need to perform maintenance on the downstream components. The critical components facilitating the collection of the data and how to interpret the data will be described. Data interpretation to communicate maintenance needs will be discussed using example scenarios.
