“Reliability is our corporate culture, the heart of our business.”

OUC’s state-of-the-art Water Quality Laboratory performs more than 20,000 chemical and bacteriological tests annually to ensure the quality and safety of OUC’s drinking water.

Ensuring Reliable, Safe Drinking Water In 1995, OUC began Water Project 2000 — the most comprehensive water system upgrade in the utility’s history. By treating the water with ozone, a strong but safe disinfectant, OUC dramatically reduced the use of chlorine in the water system and removed hydrogen sulfide, a naturally occurring compound that can create an unpleasant taste and odor in water. The result was tap water that tasted as good as bottled and it bore OUC’s name — H2OUC. H2OUC was named the best drinking water

The Copper-Lightning Connection Central Florida’s reputation as the lightning capital of the United States never became more evident after hundreds of “pinhole”-sized leaks began forming in copper pipes. During the 1980s and early ‘90s, OUC’s water department, led by laboratory superintendent Dick Dunham, determined that four factors led to accelerated pinhole leaks: lightning, water chemistry, copper plumbing grounding practices and low-quality plumbing workmanship. This was in the time period before the widespread use of PVC pipes. OUC was able to determine that better grounding of plumbing pipes could reduce the chance of a leak.
