UV Disinfection System in Miami, FL

Why Miami Homes Need UV Disinfection System

Miami (approximately 439,000 residents, in Miami-Dade County) is served by Miami-Dade Water and Sewer Department (WASD), primarily served by the Hialeah and John E. Preston Water Treatment Plants and the Alexander Orr Jr. Water Treatment Plant. Drinking water comes from Biscayne Aquifer groundwater, with approximately 330 million gallons per day withdrawn from shallow wells averaging 80 feet deep, supplemented by Floridan Aquifer water treated at the Alexander Orr plant. Hardness at the tap is moderately hard, finished water from the WASD lime-softening plants typically tests in the 7 to 11 grains-per-gallon range.

For most Miami homeowners that means visible scale on faucet aerators and showerheads within a year, water heaters that fail earlier than rated, and detergent and soap that never quite lather. A properly sized UV disinfection fixes the water that arrives at every fixture in the house, not just the kitchen tap. For regional context behind these recommendations, see our Well Water Problems in South Florida article.

How Our UV Disinfection System Works

Whole-house ultraviolet disinfection that inactivates bacteria, viruses, and protozoan cysts without adding chemicals to your water. Essential for private well owners and as a defense layer for municipal customers concerned about distribution-system contamination.

Every install starts with a real water test. We do not size off a utility average. The South Florida distribution loop carries seasonal variation, and the actual water at your kitchen sink may differ from the headline numbers in any utility's annual Consumer Confidence Report. For deeper background, read Well Water Problems in South Florida or our UV Disinfection System service page.

Miami-Specific Considerations

Miami sits in Miami-Dade County. The water you drink, cook with, and shower in is treated by Miami-Dade Water and Sewer Department (WASD), primarily served by the Hialeah and John E. Preston Water Treatment Plants and the Alexander Orr Jr. Water Treatment Plant (see the utility's water-quality page).

Notable local water-quality details:

• free chlorine secondary disinfection with TTHM and HAA5 reported in WASD's annual Consumer Confidence Report; the Biscayne Aquifer is a shallow groundwater system and the WASD CCR is the canonical record for finished-water quality (source)
• Biscayne Aquifer wellfields are surrounded by urbanization and the Florida Department of Environmental Protection and Miami-Dade DERM actively manage source water protection zones to limit industrial, agricultural, and stormwater impacts (source)

For the most current numbers (free chlorine residual, total trihalomethanes, hardness, lead and copper at the tap), pull Miami's most recent Consumer Confidence Report directly from the utility. We bring a fresh on-site test to every consultation.

Preston Water Treatment Plants and the Alexander Orr Jr. Water Treatment Plant 2025 Consumer Confidence Report, covering calendar year 2024, published by the Florida Department of Health (CCR PDF).
