Sarasota County draws water from three primary sources: the Peace River, the Myakka River, and the Carlton Reserve wellfield. Each source has distinct water quality characteristics, and the blend that reaches your tap shifts seasonally.
The Three Water Sources
The Peace River Manasota Regional Water Supply Authority delivers surface water treated at the regional facility in DeSoto County. Myakka River water is blended in during high-demand periods. The Carlton Reserve wellfield taps the Floridan Aquifer and contributes groundwater with naturally higher mineral content.
Hardness Levels
Sarasota County water typically tests between 10 and 18 grains per gallon, depending on the seasonal blend and your specific location. Homes in the northern part of the county closer to Manatee County blend tend to see higher hardness during dry season when wellfield contribution increases.
Seasonal Changes
During Florida dry season (November through April), reduced river flow means a higher proportion of wellfield water reaches your tap. This increases both hardness and total dissolved solids. Residents often notice more spotting on dishes and fixtures during these months.
What Sarasota Homeowners Should Do
A free in-home water test provides a precise snapshot of your specific tap water quality, which can differ from utility averages based on your neighborhood and plumbing age. Pure Viva tests for hardness, total dissolved solids, chloramine levels, pH, and other key parameters to give you a complete picture before recommending any treatment.
