The town of Darien is home to 21,000 people on the Gold Coast of Connecticut. Residents pride themselves on being good environmental stewards who work to preserve their pristine waterways and natural habitat. Prior to 2012, the Darien collection system was monitored by programmable logic controllers (PLC) and phone lines. Darien collection system personnel were overwhelmed with false alarms, inaccurate data and downtime, so town officials began to look for a more dependable system.
Sewer backups are an ongoing problem for municipalities in the U.S. According to the U.S. Environmental Protection Agency, up to 75,000 annual backups and overflows account for 10 billion gal of untreated wastewater discharge. Underground infrastructure management is difficult for many utilities, but there is equipment that can help them detect problems before they become catastrophic. Solutions are helping utilities nationwide take proactive measures to streamline efficiency, improve infrastructure and avoid problems.
Nestled on the bluffs of California’s Monterey Peninsula, Pebble Beach is considered one of the nation’s premier residential communities and golf resorts. It is home to multi-million-dollar estates and meticulously maintained, internationally renowned golf courses.
Deteriorating infrastructure continues to plague municipalities across the U.S., compromising local budgets and natural resources. Utility officials nationwide are actively searching for innovative strategies to circumvent these problems. When the Caryville-Jacksboro Utility Commission (CJUC), located 36 miles north of Knoxville, Tenn., began restoring its collection system, it successfully avoided $13 million in equipment upgrades and $18,000 in energy costs in just one year of implementation.
Duckett Creek Sanitary District (DCSD), located in O’Fallon, Mo., was experiencing inflow and infiltration problems, causing backups and overflows. When annual bypass reports submitted to the U.S. Environmental Protection Agency (EPA) indicated noncompliance with federal regulations, Keith Arbuckle, DCSD director of engineering, collaborated with EPA officials to improve system operation and maintenance. Both parties agreed to implement a CMOM (capacity, management, operations and maintenance) program to circumvent noncompliance fees and reduce bypasses.
Marlboro Water Co. (MWC) is a small water utility nestled in the Pee Dee area of South Carolina, a region rich with natural resources—including freshwater streams, forests dense with hardwoods and abundant wild game.
Two recent natural disasters have tested cellular networks in different ways. A 5.8-magnitude earthquake followed by Hurricane Irene struck the Eastern U.S. Call surges by cell phone users after the earthquake made voice communications difficult, if not impossible. Power outages caused by Hurricane Irene presented a different set of challenges to cellular providers. Cellular SCADA demonstrated its reliability in both instances.
Every municipality would appreciate having a brand-new wastewater treatment plant (WWTP) complete with the latest technology and energy-efficient equipment, but budgets are tight and the feasibility of a new plant is not always realistic. The quality of water, however, can benefit from improved process control. Energy cost reduction is the mantra preached daily across the country. If only it was possible to attain this benefit without funding and constructing a completely new WWTP.

Capacity, management, operations and maintenance program: Most often, this term is shortened to the familiar acronym CMOM. The ultimate goal of the CMOM process, as it applies to the wastewater treatment industry, is to assure that discharges from treatment facilities are free from pollutants. The framework of the CMOM program allows for periodic reviews of a collection system by the U.S. Environmental Protection Agency (EPA) and state inspectors to assure compliance with the program elements.
Bluegrass State sewer and water departments adopt new telemetry solutionsIn today’s world of increasingly complex technology, two very different utilities with very different issues came to similar solutions regarding their telemetry needs. A quickly deployed and easy-to-use SCADA system is adaptable to a variety of problems commonly faced by modern water and wastewater operators.

Combining conventional and cellular SCADA yields increased performance and big savingsIn the last four years, there have been dramatic changes in the use of cellular services for SCADA telemetry.
Nationwide high-speed data services have been deployed by all major carriers, which now provide coverage virtually anywhere there are population centers. As cellular to Web-based services have gained popularity and acceptance, some utilities have had to choose between traditional SCADA and CCWD SCADA.
