Big Data is on the minds and lips of many water system managers, but how many utilities are actually utilizing it? Jason Carter, the Water Utility Innovation Leader at Arcadis, lamentedly states that the water industry is behind, but he also sees a clear path forward — one where Big Data plays a central role in operations and, consequently, newfound efficiencies. In this Water Talk interview, Carter provides examples of how utilities can leverage data for improved operations, pinpoints the cost savings associated with Big Data, and forecasts the future in terms of adoption and implementation.
Jeff Garner, Senior Vice President with MWH Constructors, covers a lot of area in this Water Talk interview, which focuses on alternative project delivery models (particularly the construction manager at-risk (CMAR) approach), the water-energy-food nexus, and the thermal hydrolysis process (THP) for on-site energy generation. Garner summarizes the essential questions for both utilities and industry: "How can I get the quality job, delivered on time, safely ... and at the budget I can afford?" Click on the player below to hear Garner's thoughts on available solutions.

Listen to this Water Talk interview with Christina Brown, Director of Program Management at Brown and Caldwell, to learn about the EchoWater project, which will allow the Sacramento Regional County Sanitation District — the largest inland discharger west of the Mississippi — to reuse half of their discharge while also reducing nitrogen loading into the Sacramento River.
James Schlaman, Director of Water Resources at Black & Veatch, explains what community-based public-private partnerships (CBP3s) are (and what they aren't), how they work, and what makes them attractive — particularly for stormwater management improvements.
There’s a lot to be said for the old adage, “Use the right tool for the job.” When it comes to flow meters for municipal or industrial water treatment plant (WTP) and wastewater treatment plant (WWTP) operations, however, the sheer number of choices can be overwhelming. That is where using a process of elimination to winnow out styles that don’t fit the performance criteria of an application can make it easier to compare the few remaining options. Here is a checklist of considerations to accelerate that process.
Silicon carbide, or SiC, membranes are made from one of the earth's hardest natural materials, making them extremely strong and resilient. They are also hydrophilic, lending to a high flux rate (4 to 6 times that of other membranes) and making them particularly suitable for stormwater/CSO applications.
A joint effort between the city of Hollister, the San Benito County Water District and the Sunny slope County Water District, the group proposed the West Hills Water Treatment Plant (WHWTP) project to improve drinking water quality, water supply reliability, and to balance regional water resources in the Hollister Urban Area (HUA). Historically, HUA relied primarily on local groundwater basins for meeting their drinking water demands. While groundwater met all drinking water regulations, it is high in minerals and hardness that often resulted in scaling and the need for further conditioning. Along with other initiatives, the WHWTP project enables the District to meet these goals through increased surface water capacity from the San Luis and San Justo Reservoirs.
Japan plans to release radioactive water tainted by the crippled Fukushima Dai-Ichi nuclear plant into the Pacific Ocean.
Reliable and effective disinfection is a cornerstone of water and wastewater treatment, needed to protect public health. Most drinking water utilities are required to maintain a minimum disinfectant residual in the distribution system. This ensures adequate chemical was applied and remains in the system to kill pathogens. The most commonly used disinfectants — chlorine gas and bulk sodium hypochlorite — require operators to regularly handle these hazardous chemicals. Operators must be extensively trained in specialized procedures to ensure their safety and that of the community.

As water and wastewater treatment plant (WTP/WWTP) processes and control systems become more sophisticated, maximizing operator effectiveness becomes more complex as well. A well-planned alarm and control strategy can make a significant difference between valuable decision-making information and confusing, disjointed, data points. This article highlights key strategies for foreseeing problems in advance, fixing them faster, and having a higher success rate by maximizing operator effectiveness.
Water and wastewater treatment applications encompass a wide range of processes, technologies, and physical/chemical methods. Among them, filtration and separation technologies are the core of treatment processes, and in many cases, they can be critical process bottlenecks. Engineering firms, engineering procurement and construction contractors, and end users have high expectations regarding a plant's operation, process design, efficiency, and performance.
There are a variety of costs that are easy to overlook in water treatment. But as Herman Coello, Products Manager for SIEMENS Process Instrumentation, explains in this Water Online video, accurately measuring your flow and treatment parameters can reduce them all. Much-overlooked expenses such as pumping inefficiencies and chemical overdosing can all be reduced to save operating expense.
In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District).

The fate of a water utility in Indiana lies in the hands of a court.
In water plant operations, there’s no such thing as simply maintaining the status quo. Any utility that is not moving forward is falling behind. Whether a water treatment or wastewater treatment plant (WTP/WWTP) chooses to rely on in-house resources or outside specialists, here are some lifecycle management approaches they can use to upgrade control capabilities without compromising performance or return on investment.
Boiler feedwater is comprised of two very important, and increasingly expensive resources: steam condensate return and city (or well) makeup water. The condensate is valuable due to low electrical conductance, purity, and high temperature. The makeup water is valuable because it is being overused and under conserved in many parts of the country, making the cost of water rise in almost all parts of the U.S.

While the laws of physics and chemistry have not changed, the ways that water and wastewater treatment plants (WTPs/WWTPs) are being forced to deal with them certainly have — e.g., disinfection byproducts (DBPs), tighter turbidity standards, harmful algal blooms, and PFAS challenges. Even when plant throughput stays the same, the demands on plant personnel continue to increase. Here’s how evolving toward better workforce management processes can help.
The City of Paramount conducted a pilot study for arsenic, manganese and iron treatment system at their Well 15 site. The onsite pilot test was designed to demonstrate the performance of the Loprest Water Treatment Company treatment process proposed for the new treatment plant.
When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life. Whether new water sources are surface water or groundwater, fresh, brackish, seawater, or water recovered from aquifer storage, they can ultimately impact water treatment plant (WTP) operations and finished water quality — including compliance with the U.S. EPA Lead and Copper Rule.
Prioritizing and funding pressing infrastructure needs can be challenging for water treatment and wastewater treatment plants (WTPs/WWTPs) of any size. The problems are particularly stressful for smaller utilities where a thin layer of upper management staff wears an inordinate number of hats. The good news is that funding assistance does exist — if you know where to look for it and take the right steps to apply for it.
