Dos Llaves Enterprises, LLC is the sole Dealer of MicroSepTec EnviroServers in Southern Arizona. The EnvirosServer ES is an alternative On-site Wastewater Treatment System designed to provide onsite waterwater treatment while protecting and preserving the surrounding environment. After installing and researching numerous other alternative septic systems, we've found the MicroSepTec EnviroServer ES to be superior in performance, quality and value.

The EnviroServer ES is an ideal solution to the treatment of household sewage in Arizona, due to the desert's unique environmental conditions. MicroSepTec's proven technology meets Arizona Department of Environmental Quality's effluent requirements to be used with subsurface drip dispersal which can be wrapped around the property, rather than discharging in a designated area. We can also provide referrals to reputable engineers for design, as needed.
