Pima County Wastewater continues to improve odor control at treatment plants

Sometimes, the perfect solution turns out to be right under your nose. 

In this case, the problem was an outdated odor control method being used at the Tres Ríos facility, the Pima County Regional Wastewater Reclamation Department’s largest treatment plant. 

The solution not only saves the County money, but also removes odors more efficiently — and even reduces the plant's carbon footprint.

Cooler temperatures come with the fall. It’s common to feel less thirsty in cold weather, but we all need to be aware that cold-weather dehydration exists. Dehydration occurs when the body doesn’t have enough fluid to function properly. Regardless of the temperature, staying hydrated is important all year round.

Wastewater Fact of the Month

palo verde tree

How can trees cause sewer backups?

While trees are an essential part of the ecosystem, their roots can pose a threat to plumbing pipes. The roots of a tree will naturally grow toward water and nutrients, which means that they can grow into sewer lines if there are cracks that permit them to enter.

If someone flushes a wipe or something else that isn't suitable for flushing, the tree root can trap it and cause a serious clog. To help protect pipes from tree root clogs, it's best to avoid planting trees, shrubs and other large plants near sewer lines.
