Waste Water

Our mission is to protect the public health and the environment through a program of responsible environmental stewardship and management, which includes source control, wastewater treatment, inproved International Outfall Interceptor (IOI) monitoring. The City's program is committed to providing quality service, taking an aggressive approach to pre-treatment and pollution prevention to minimize toxic discharges to the sewage system.


To prevent the discharge of pollutants as mandated under the Clean Water Act, to prevent the passing into the International Outfall Interceptor (IOI), improve the reclamation of the municipal wastewaters and biosolids coming from Nogales, Arizona.

Enforce all applicable Environmental Protection Agency (EPA) wastewater quality standards and reduce the risk to health and environment caused by wastewater discharges in the conveyance system.
