CSA 18 Sewer Service Moratorium
| The 2025 Capacity Study served as a basis of existing and future capacity of the system’s wastewater treatment plant based on flow, permitted capacity, BOD, and nitrogen. The study was used to provide recommendations for improvements to the wastewater treatment system and determined that no additional connections should be allowed as the Small General Permit limits have already been exceeded in some cases. The Capacity Study and Ordinance are linked here. |
