IRWD contractors will be making improvements to several of the district’s sewer siphons.
Sewer siphons divert sewage flow under, over, or around an obstacle such as a creek. Improvements at each site will vary.
Construction is expected to take place from April 2025 to April 2026, with each location taking about two months to complete.
