Respecting every drop
When water goes down the drain, it doesn’t just go away. Instead, it travels through the sewer system to the District’s Nine Springs Wastewater Treatment Plant, where it is cleaned before being returned to the environment as safe, fishable and swimmable water. While we do remove many pollutants at the plant, some are costly and challenging to take out. Fortunately, pollution prevention can help.
Through education, outreach and innovative program design, our Pollution Prevention team works diligently to keep pollutants such as chloride, mercury, pharmaceuticals and others from reaching the plant in the first place. By keeping these items out of our wastewater, we can help protect clean water while keeping sewer bills low.
