Title
Annual Update on Wastewater Systems
Body
The board has requested a system assessment on a different utility each quarter. This quarter,
Clay Moseley, Deputy Utilities Manager for GWS Operations, will present an update on the wastewater systems: wastewater collections and wastewater treatment. Discussion includes both the physical condition and operational challenges of the wastewater sub-systems: Wastewater Collections (WC) and Wastewater Treatment (WT). Also included are recent AMT (Asset Management Team - Engineering and Operations) achievements and challenges and planned near-term future O&M Goals, Action Items and Major Projects.
The physical condition of each sub-system (WC = FAIR, WT=GOOD) has seen some upward improvements from last year’s report. This is the result of AMT goals moving into their project phase, with several of the projects being successfully completed. Project completion from both CIP and in-house Operations contribute to improvements. Large systems require multiple years of CIP and O&M improvement projects before the entire system's condition can be revised to a significantly improved status. The AMT program focuses on prioritizing the most critical issues from most impactful to less impactful.
The new White Rock WRRF is now fully functional after being put into operation two years ago. It truly is a source of pride for the DPU and the WT staff enjoy operating it. It has had a few startup issues, most of which have been mitigated by the project team, but one large issue with the sludge basin mixing pumps is still being worked on. There is an aggressive corrosion problem, the source of which is not fully understood and requires further investigation.
The Los Alamos WWTP has seen several major upgrades and replacements this past year, which has resulted in a significant improvement in its overall condition assessment. The original solids dewatering belt press has been replaced with a more modern, resource efficient ...
