Established in 2017

Operating a public water system can be very costly and labor intensive for small businesses and independant utility owners. Potable drinking water is a significant responsibility and liability. In order to provide drinking water to the public, owners of public water systems must comply with all regulatory requirements. Potable water must be treated, tested, and reported in accordance with state and federal regulations.

We have over 26 years of combined experience in the water and wastewater industry. In 2017, we formed our own company, Rural Environmental Service, LLC (RES), in order to help local businesses and private utility owners manage and operate their public water systems.

We look forward to partnering with you.

Rural Environmental Service has been wonderful to work with in completing my CSI Inspections. Their process makes things super easy and takes care of filing the appropriate paperwork that’s required. I look forward to working with Rural Environmental Service in the future for all my inspection needs.
