5 Common Wastewater Challenges And How To Mitigate Them

By Jesus Rodriguez

Wastewater utilities face a complex mix of challenges—from aging infrastructure and rising demand to limited budgets and staff shortages. Yet the most persistent problems often stem from familiar culprits: rags, grit, variable flows, odor, and financial constraints. Each can cause serious operational issues, from pump clogs and aeration failures to odor complaints and unplanned downtime. Fortunately, targeted solutions exist. Grinders prevent rag buildup in unmanned pump stations, while grit removal systems and high-capture-rate (CRE) screens protect downstream equipment. Washer compactors not only control odor by removing biological residue from screenings but also reduce waste volume by up to 90%. Balancing performance and cost is essential—technologies like channel rotary screens offer high CRE with lower head loss, improving reliability and efficiency. Just as importantly, regular maintenance of headworks and collection systems ensures long-term ROI. With the right equipment and proactive care, utilities can effectively mitigate their toughest wastewater challenges and sustain reliable treatment performance for years to come.
