Fast-Track Your Arizona
Land Development Project
With Our Expertise

Break ground faster with ADEQ permits in 8 weeks instead of 12 months. We deliver complete submittals, predictable costs, and systems designed for Arizona’s desert conditions and groundwater management requirements.

What We Do

Modern Engineering Solutions supports Arizona developers with water, wastewater, and civil engineering in Active Management Areas and throughout rural counties.

Wastewater Engineering

Arizona wastewater projects split between connecting to municipal systems in Phoenix or Tucson and building private package plants where central sewer doesn’t exist. We determine if your site qualifies for an Aquifer Protection Permit or needs a reclaimed water facility under Arizona’s reuse regulations. Desert soil conditions mean different infiltration rates than you’d see anywhere else, so our collection system designs account for caliche layers and expansive clay that standard hydraulic models ignore. ADEQ wants proof of adequate disposal capacity before issuing APP permits, and we’ve secured approvals in Maricopa, Pima, and Yavapai counties. Your contractor gets drawings that work in 115-degree heat with soil that shifts seasonally.

Water Engineering

Water availability drives every Arizona development decision. Active Management Areas require assured water supply demonstrations before you can even plat your lots. We handle the Certificate of Assured Water Supply application process with ADWR, coordinate with private water companies on will-serve letters, and design distribution systems that perform under extreme temperature swings and high mineral content. Phoenix metro projects need CAWCD allocation documentation. Tucson developments deal with Central Arizona Project water and local treatment requirements. Rural Yavapai and Cochise County sites evaluate well depth feasibility and pumping costs that can kill project economics. We tell you upfront if your water supply assumptions are realistic or if you’re looking at costly surprises later.

Civil Engineering

Desert site design means managing flash flood potential that goes from zero flow to channel-filling in twenty minutes. Arizona counties enforce FEMA floodplain requirements aggressively, and washes that look dry eleven months a year determine where you can’t build. We size retention basins for monsoon events that standard rainfall curves don’t capture, coordinate utility corridors to avoid desert washes, and design access roads that won’t wash out when arroyos activate. Pinal County has different drainage standards than Maricopa County. Yavapai County adds wildfire access requirements. Coconino County projects deal with high desert conditions and winter freeze concerns. Site layouts that ignore these regional differences get rejected at plan check or fail during the first monsoon.

Construction Administration

Arizona construction schedules revolve around beating summer heat and monsoon season. Concrete work stops above 100 degrees unless you’re doing night pours with special mix designs, and utility trenching during monsoon means dealing with unexpected groundwater that shouldn’t exist in the desert. We schedule observation visits around weather windows, review mix designs for high-temperature placement, and inspect backfill compaction in soils that test differently when dry versus saturated. ADEQ startup inspections for wastewater facilities require operational testing during actual flow conditions, not theoretical design flows. Your project closes out on time because we planned construction sequencing around Arizona’s weather extremes, not a generic calendar.
