Cleaning day at WLSSD! 🧼

Wastewater and stormwater systems use sediment tanks (sometimes called settling basins, grit chambers, or sedimentation ponds) to allow sand, silt, gravel, organic material, and debris to settle to the bottom before the water moves on.

The sediment has to be cleaned out periodically because:

1. Maintains treatment capacity – As sediment builds up, there is less room for water. The tank can’t hold or treat as much flow during storms.
2. Prevents sediment from being carried downstream – If the tank fills with accumulated material, heavy rain events can stir it up and wash sediment into rivers, lakes, wetlands, or the next stage of treatment.
3. Protects equipment – Grit and sand are abrasive and can damage pumps, pipes, valves, and other equipment if allowed to move through the system.
4. Reduces pollutants – Sediment often contains pollutants such as phosphorus, nitrogen, oils, grease, heavy metals, road salt residue, and bacteria. Removing the sediment removes those contaminants from the water system.
5. Prevents odors and anaerobic conditions – Organic material trapped in the sediment can decompose, producing foul odors and potentially harmful gases if left too long.
6. Regulatory compliance – Many municipalities are required by state and federal permits to maintain stormwater treatment structures and document sediment removal to meet water quality standards.

A special thank you to the Firefighters and Rescue Teams across Minnesota who have been working tirelessly to contain and extinguish the fires throughout the state. Your dedication, quick response, and long hours do not go unnoticed.

We received a call that some of our equipment was at risk due to an approaching fire. Thanks to the proactive efforts of these crews, we were able to safely move our equipment, and they successfully contained the fire before further damage could occur.

We are incredibly grateful for all of your hard work and sacrifice, especially over these past several weeks. Thank you for all that you do to protect our communities.
