Welcome

“We design It, We install It, We Stand behind It.”
America is faced today with the challenge of a rapidly expanding population, greater demand for scarce resources, and the challenge of finding responsible and renewable ways to manage and utilize those resources.

In California, new innovative technologies are being introduced to the market that vastly advance wastewater treatment processes. Engineered Septic Systems (ESS) was formed because we recognize that there is a huge demand for safe, alternative treatment systems that provide approved wastewater treatment that meets the demands of a growing population and protects our increasingly limited water resources. Now, we have those systems.
