Why Phoenix County Islands?

Phoenix's urban footprint contains dozens of unincorporated county islands — pockets of land governed by Maricopa County that still require private septic systems. These lots face unique challenges: tight setbacks against neighboring city-sewered properties, limited space for conventional drainfields, and sometimes legacy systems that need replacement to meet current code. Our team specializes in engineering solutions for these constrained infill parcels.

Projects We Handle

  • County island infill construction
  • Legacy system replacement and code compliance
  • ADU additions on septic-served lots
  • Commercial properties on unincorporated parcels
