Collier County is planning one of its largest infrastructure investments to date—a long-term utility expansion project that will support continued growth and development primarily in the northeast region of the county.
Often referred to as a “$700+ million sewer project,” this initiative is part of a broader, multi-phase effort to expand both wastewater and drinking water systems. The project includes the construction of new treatment facilities, water storage, and an extensive network of pipelines designed to serve future residential and commercial development. The following table provides a Rough Order of Magnitude (ROM) estimate of the various components of the system expansion.
As Collier County continues to grow, so does demand for essential services such as water and sewer. Infrastructure is built years in advance to support new communities. Future development is limited by infrastructure. Expansion of the utility system into the northeast expands the utility service area. The distance of pipe required for connectivity adds considerable costs above urban area water/sewer infrastructure.
Collier County generally follows a “growth pays for growth” model. This means that much of the cost for new infrastructure is funded by impact fees paid through developers, rather than through general taxation. While development helps fund construction, the ongoing costs of operating the system—such as maintenance, staffing, and upgrades—are typically covered through utility rates paid by ALL customers. Although the expansion is primarily driven by growth, current rate payers will see increases in their utility bills over time. Wastewater (sewer) rates are expected to rise in the coming years as the County invests in maintaining and operating a larger, more complex system.
System operating costs are increasing due to increasing personnel costs, rising chemical costs, and replacement costs of the aging, existing infrastructure. This is best illustrated by reviewing the recent rate increase table below that reflects approved rate increases through 2029. Water rates will have increased 55.73% and wastewater rates will have increased 74.23%. This will add an additional cost burden to a housing market already near the highest in Florida.
