Innovation is paying dividends for the growing list of municipalities that leverage the latest technology to optimize planning and operations decision making.
The utility sector mirrors what happens with the general industry and construction sectors throughout America.
“Wastewater Dan” instructs operators on how to perform calculations for combining concentrations.
Substances regulated or substances unregulated may ultimately impact the environment, health, and water supply of others. The following safety considerations are advised for those who store, handle, or transport potentially dangerous substances.
Looking around the room at the Southwest Membrane Operators Association (SWMOA) board meeting, it was brought to my attention that this was the first time SWMOA has had two women on the board of directors — myself and Christiana Daisy, Operations Manager at West Basin Municipal Water District. Pretty impressive, considering that female representation in SWMOA has only been ~10 percent since its inception in 2006.
There are a variety of reasons for wanting accurate flow metering — e.g., billing purposes, precise proportioning of chemical injections, and other process flow decisions. That is why highly accurate mag meters are so popular in many applications. Now, new lightweight, corrosion-resistant mag meters provide the same advantages as plastic piping for harsh environments and flows that cover all the bases…and acids.
For many water-distribution workers and managers up to their elbows in muddy trenches and SCADA data, the drumbeat for ‘Big Data’ probably fades to background noise when dealing with immediate leaks and losses on the front lines. Don’t throw the baby out with the bathwater, however. Many answers we truly want are probably accessible through current water distribution data. We just need an easier way to wring them out.
With a continuous flow of air required to maintain dissolved oxygen (DO) levels, the last thing a wastewater treatment plant (WWTP) operator wants is to come up short of the volume needed to sustain good microbial growth. With today’s ready availability of high-efficiency rental blowers, losing blowers to unplanned downtime or being unable to test new aeration systems before commissioning are no longer the threats they once were.
For most water utilities, maintaining existing infrastructure — whether planned or in response to emergencies — is a large part of physical plant costs. Being prepared to respond is half the battle. Here are several guidelines and options to consider for maintaining the most cost-efficient solutions to everyday pipeline problems. As with most good plans, they start with proper organization.
Today’s water/wastewater piping options offer numerous advantages in terms of cost, performance, and anticipated service life. Unfortunately, utilities must still deal with what’s already in the ground — steel, cast iron, ductile iron, asbestos cement, plastic, concrete, and even wood. Here are guidelines on making transitions between old and new pipes of varying sizes and materials as smooth as possible.
When one considers all the bell joints in a water distribution or wastewater collection system — caulk-joint or rubber-joint — and all the stresses to which they are subjected, it is a wonder there are not more leaks. Fortunately, bell-joint-leak clamps provide a reliable and relatively easy-to-install solution — if they are properly specified and installed. Here are some key points to consider when trying to remedy bell-joint leaks.
Every city facing infrastructure or operational challenges or concerns about maintaining quality of life in the face of population growth or a changing environment has benefits to gain from a unified smart-city approach. Here are some concepts for promoting understanding and acceptance among utility and government decision-makers, plus several examples of benefits already being garnered by smart cities large and small.
Reasons for changing water or wastewater asset management practices include unacceptable process downtime, statutory requirements for documenting infrastructure integrity, or the desire to refine process cost-effectiveness and maintenance-budget ROI. Here are examples of strategic approaches that can better match desirable asset management outcomes to the real needs of water utility operations.
Illinois American Water Peoria District Sr. Project Engineer Josh Harken has been named the Young Civil Engineer of the Year by the Central Illinois Section of American Society of Civil Engineers (ASCE).

OPSWAT, a leader in critical infrastructure protection, recently announced a new critical infrastructure protection (CIP) cybersecurity training and certification program, OPSWAT Academy.
Teams from Colorado and Texas bested the rest during the 32nd annual Operations Challenge competition. The Rocky Mountain Water Environment Federation’s Elevated Ops from Denver won Division 1 and the Water Environment Association of Texas’ South Mesquite Rangers from Mesquite placed first in Division 2. The exciting, high-energy event happened at WEFTEC 2019—the Water Environment Federation’s 92nd annual technical exhibition and conference—in Chicago.
Recently, the U.S. Environmental Protection Agency (EPA) announced the Water Workforce Initiative to help cities and communities across the country that are facing critical staffing shortages for the operation and maintenance of essential drinking water and wastewater infrastructure.
