A septic tank manufacturing company and custom home builder could soon bring 30 to 40 jobs to unincorporated Pinal County. The Pinal County Planning and Zoning Commission recommended approval of the Sunset Companies industrial development on January 15, 2026. The project would allow Sunset Companies and San Tan Construction to operate on approximately 18.12 acres north of the Town of Florence in unincorporated Pinal County.
Two Local Businesses Set To Operate On Site
Sunset Companies manufactures and services septic tanks. The operation requires a large outdoor area for concrete casting and curing. San Tan Construction builds custom homes throughout Pinal County. Both companies plan to base their operations at the new facility.
The businesses expect 15 to 20 workers on-site daily. Another 15 to 20 employees would work in the field serving the community.
Traffic studies estimate the facility would generate 145 daily vehicle trips. Peak morning traffic would add 29 trips, while evening rush hour would see 32 trips.
