SCADA & AUTOMATION CASE STUDIES AND WHITE PAPERS
A municipal water quality manager reports replacement of sodium hypochlorite (hypo) vacuum feeder units with a more advanced type at one water treatment plant (WTP) has helped allow for continued reliability for chlorination.
Three Steps For Reducing Total Cost Of Ownership (TCO) In Pumping Systems
Energy costs have become an increasing contributor to pumping systems Total Cost of Ownership (TCO). In fact, energy cost represents 40% of the TCO of a typical pump. It is possible to reduce the electrical consumption by at least 30% utilizing Variable Speed Drives while decreasing maintenance costs associated with the mechanical driven system. This paper explains how to reduce TCO with a limited investment focused on three key areas: energy efficiency management, asset management, and energy cost management.
Reliable M2M Communication And Networking Technology Connects Wastewater Facilities
As the world becomes increasingly connected, the integration of smart devices and tools, such as sensors, process control devices, security cameras, for example, have increased the need for well-established, secure machine-to-machine (M2M) communication and networking solutions. Many companies depend on effective communication technologies to reduce overhead costs and improve their bottom lines.

Identifying And Estimating The Value Of SCADA And Smart Metering Systems In Water Distribution Networks
Considering the invaluable service provided to the society by the water companies, it is imperative to ensure their sustainability. To achieve this objective, these organizations must be allowed to fulfill their mission with effectiveness and efficiency. Information and communication technologies are especially important tools in this pursuit of enhanced performance.
Make Your SCADA Feel Young Again
When the Village of Romeoville underwent a major upgrade to their SCADA system, they also decided to move to the latest version of the monitoring & control software that they had used successfully for many years. This version included features designed specifically for the water/wastewater industry. In this article, a former Head of the Water Department (*) explains why the utility continues to push for the latest HMI version and how this helps them overcome many of the issues related to maintaining a long-running SCADA system.

SCADA Alternatives For Remote Monitoring
In addition to managing operational efficiency and customer usage, utilities are driven by demanding regulations for improved quality, safety, and security. For remote monitoring applications, data acquisition systems (DAS) can provide an enhanced understanding of network operations through detailed documentation. This white paper presents the advantages of remote DAS over SCADA, including the ability to measure data even when communication channels fail or computers crash. By Barry Ceci
Cooling Electrical Panels In Waste Water Treatment Applications
Over the past few decades, the use of sophisticated electronics for automation and process controls as well as transformers, VFDs and PLCs have become commonplace in NEMA enclosures. The thermal management and related costs of these electronic enclosures has become very important considerations in managing these valuable assets.
AZ Utility Breaks New Ground In Water Reuse With Help From VTScada Software
The Fountain Hills Sanitary District (FHSD) provides wastewater treatment for over 13,000 homes and businesses. In addition to supplying the town’s namesake fountain, its treated water irrigates local golf courses and parks. In 2000, the utility developed an innovative way to make up the short-fall during the dryer less populated summer. By Christopher Little
Wireless Lift Station Monitoring Application Note
Lift stations are remote pumping facilities that move wastewater from lower to higher elevation. Monitoring lift stations is important to collection system operators.
Water Distribution System Wireless Monitoring Application Note
Providing water distribution monitoring solutions since 1987, Telog continues to offer the industry’s leading remote data acquisition system including the most comprehensive family of battery powered, environmentally rugged wireless monitors available from any single supplier.
Wireless PRV Monitoring Application Note
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
Hydrant Pressure Monitoring Application Note
One of the most popular uses for the Telog Hydrant Pressure Recorders (HPRs) is to monitor and analyze customer pressure complaints. The HPR is ideally suited for this application because it is rugged, highly portable, and can give a complete, time stamped picture of the pressure differential between the customer’s water pressure and the water pressure being delivered by the utility.
DCS Versus PLC: A User's Guide To Selecting The Most Effective Control Platform For Your Application
Distributed control systems (DCSs) and programmable logic controllers (PLCs) are not mutually exclusive technologies. When the end-use application serves as the basis for making a sound decision, the selection process becomes more efficient, and a more effective outcome results. This white paper provides general guidelines and highlights key considerations when choosing a control system platform. While the details of each application are critical to the selection process, use the following as a guide when designing, specifying, and implementing controller technology. By Jim Hazelwood and Bill Butler, Revere Control Systems
In the early 1990s, the Borough of Ridgway purchased several separate systems to control their water treatment and five bay filtration processes. Through the years, technology obsolescence led to difficulties in obtaining support and spare parts for all the systems. At one point, the existing systems completely failed, leaving Ridgway employees to manually operate the plant for several months. A new, more efficient system was desperately needed.
