Wastewater Facilities Improvements – Phase 1

While Maupin’s wastewater collection and discharge systems have enough capacity to meet our population estimates through 2024, the facilities are aging in need of major improvements and, in some cases, replacement in order continue to meet DEQ’s requirements for redundancy and reliability.

Background

In 2023, the City completed the Wastewater Facilities Plan, a document that will guide the City in improving and expanding our wastewater collection and treatment facilities for the next twenty years. These projects are outlined in the plan or will be included as amendments, based on the recommendation of City staff and Council.
