Who We Are

Home / Who We Are

Your partner in protecting public health and the environment

We are a passionate and experienced resource recovery team that aims to protect public health and the environment by providing safe, reliable and efficient wastewater treatment to our communities. We’re known for our innovative engineering, conservation leadership, recovery expertise and we’re cost-conscious ratepayers, just like you. It’s who we are.

At the District, our vision is to enrich life through clean water and resource recovery. Every time our essential workers clean and return wastewater back to nature or apply Metrogro to help farmers grow more food, we’re taking steps to create a cleaner and better world. We do this by not only providing critical infrastructure and public services to the communities we serve, but by providing education and doing public outreach so others can take steps to conserve our resources.

WATER IS FINITE.
We can’t create more of it.

We have the power to enhance the quality of life on our planet together. By making small changes and respecting every drop of water we have today, we can set the tone for a resource-conscious and sustainable community tomorrow.
