Peel may have to wait an extra year before it gets a sewage treatment plant.
Manx Utilities will present its annual report to Tynwald for approval when the court sits next week.
The document outlines the organisation's future plans, and says it now aims to have Peel's sewage works operational by December 2025.
The original target date was December 2024, and Manx Utilities says it will try to complete the project earlier if possible.
