Septic to Sewer Program

Many septic systems in St. Johns County were installed decades ago and can be difficult to maintain, especially in areas with high groundwater or frequent flooding.

Over time, even well-maintained systems can release nutrients and bacteria into groundwater. In coastal areas, this groundwater can flow into nearby creeks, rivers, and the Intracoastal Waterway.

Septic to sewer is being explored as a long-term approach to:

• Protect water quality
• Support public health
• Preserve natural environments

Septic-to-sewer projects are evaluated based on community input, infrastructure feasibility, and long-term planning considerations.

St. Johns County Utilities works with communities to:

• Gather input and understand interest
• Evaluate infrastructure needs and costs
• Identify potential project areas
• Share updates as planning progresses

Community participation helps inform planning and supports efficient infrastructure solutions.

Total cost of $8,155.05

This includes:

• Sewer infrastructure charge
• Sewer unit connection fee

*Other fees may apply

*Cost reflects fiscal year 2026 approved rates

*Consumer price indexing occurs every October 1^st

This updated structure provides a more consistent and predictable cost compared to previous policies.

In addition to the public cost, homeowners are responsible for on-site private plumbing work. Costs vary depending on property conditions.

Converting from septic to sewer helps protect the natural recourses that define St. Johns County.

Key benefits include:

• Reducing the risk of pollution entering waterways
• Improving protection of rivers and coastal ecosystems
• Supporting long-term environmental health
• Increasing resilience in flood-prone areas
