This inspection primarily focused on current known deficiencies effects on the WWTP relating to hydraulic loading and current plans moving forward. The city has demonstrated excess flow at the WWTP is not due to growth but I&I throughout the collection system. The Town is currently utilizing an AIA grant to digitally map the system and determine the extent and state of the collection system. Much of the system is terracotta and it is suspected the lines are heavily influenced by stormwater into the system through cracks and leaks in the pipes. The City is requesting new sewer extension projects have shapefiles so the upcoming GIS Map can be immediately updated. The City is attempting to replace as much aging infrastructure in-house as possible under deemed permitted action and eliminating sections of line that are no longer in use or needed. Flow swings are increasingly common at the WWTP with less rainfall amounts due to system wide issues. The preliminary engineering report prepared for the City by High Country Engineering has identified several upgrades to utilize the awarded $160,000 from ARPA funding. The City plans to replace approximately 600 LF of clay line with 8” PVC from Poplar to Gaffney and a brick manhole along Pace St. and US 176 is also slated to be replaced with a new precast manhole. Almost the entire system is cleaned in-house annually and observed at that time. The City has purchased a vac truck since the TA inspection in 2019. Laurel Dr. LS has been replaced and previous issues have been resolved. This LS was the site of recurring overflows during storm events. Two spare pumps are also now available for this lift station. Forest Creek LS: The City is currently resolving a property issue at this lift station. Pearson Manhole: Previous overflow issues at this low-lying manhole were due to debris. This appears to have been resolved according to facility staff. No reported SSOs at this location since 2019. It was recommended the City apply for the upcoming APRA funding round through DWI as extensive collection system work is likely required to reduce the hydraulic surges during wet weather. The ADF for 2021 was 0.047 MGD. I&I from the collection system is inhibiting the proper operation of the WWTP during rain events. The ORC reports rain events as low as 1.5" are now causing issues at the facility. During rain events, the City often reports the blowers have to be shut off to allow the plant to settle and prevent further visual solids loss.
