By Christopher Little
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
Intuitive means many things to many people, but most agree that intuitive designs should work for you and not the other way around. It simply doesn't feel intuitive if you must source third-party products to make the solution work - like historical databases, OPC drivers, alarm notification, application version control.
Glenn Wadden, President of Trihedral, explains how today’s SCADA systems are intuitive to learn for remote plant operators and capable of providing feedback that can reduce cost and increase efficiency.

Internet-hosted SCADA systems are a modern answer to modern municipal water and wastewater concerns. By Thelma Akwei and Ben Manlongat
When creating SCADA specifications, engineering firms must focus on meeting the immediate start-up and operational requirements of the SCADA system. This often means specifying products with which they are familiar. The engineer wants to ensure that the new system meets all start-up requirements at a reasonable price. It is often difficult to look past the immediate project and consider long range plans, cost of system maintenance, and keeping your SCADA application current with evolving technology.
Developers at the City of Sacramento and Trihedral Engineering recently completed the first phase of the utility’s Supervisory Control & Data Acquisition (SCADA) Software Replacement Project.
Houghton Lake Sewer Authority staff were concerned that the aging computer running their SCADA software application was in danger of failing. However, their budget constraint was cost-driven and required that any new, fully featured system be up and running in under a week.

Ocean Isle Beach is a small island community on the southeast coast of North Carolina. Only about five-hundred people live there year round, but during the summer months its beautiful beaches draw almost ten times that number. This poses unique challenges for the town's wastewater utility who must handle this extreme seasonal spike in usage.
The residents and industries of Providenciales Island are completely dependent on fresh water produced by a single desalination plant. In 2007, ITT Flowtronex was hired to replace the plant’s overworked pumping system and add a booster pumping station to the distribution system. One of the challenges they faced in designing controls for the system was how to maintain the public water supply while the island’s undersized ground water storage tanks were removed and replaced with a large single tank in the same location, a three to four month process. By Richard Embry and Christopher Little
Trihedral is proud to announce a fresh approach to helping utilities reduce the cost of expanding their supervisory control and data acquisition (SCADA) systems. This includes an innovative 'Site Import Utility' soon to be integrated into the latest version of their VTScada HMI software. The utility allows municipal workers to plug in new monitoring and control devices and then watch as VTScada does the rest of the work.
VTScada HMI software from Trihedral Engineering has long supported automatic failover of both application servers and internet servers.

Each plant had its own separate monitoring and control system that allowed it to function autonomously
The Gainesville Regional Utilities is the fifth largest municipal utility in Florida and serves just over one hundred thousand people. The utility operates two wastewater treatment plants as well as 165 lift stations. Together, these facilities process approximately 20 million gallons of wastewater a day. In 1999, the Gainesville Regional Utility began utilizing VTScada to control and monitor its lift station network. When staff compared this to what they were using in their treatment plants, they saw an opportunity to unify their system and open up their proprietary SCADA central

When the Georgetown Municipal Water & Sewer Service evaluated the cost of upgrading their existing SCADA software in 2006, they decided it was time to consider replacements. After much research, it became clear that not only was it possible to get all the features they were missing; they could do most of the configuration in-house
