We work with developers, municipalities, and civil firms across Arizona to deliver infrastructure that meets ADEQ water quality standards and ADWR allocation requirements in the nation’s most strictly regulated desert environment.
From Phoenix to Tucson and communities throughout Active Management Areas, we design systems for Arizona’s groundwater constraints and extreme climate, delivering permits in 6–8 weeks instead of 12 months.
Development across Arizona stops when firms design infrastructure without understanding groundwater depletion, Active Management Area restrictions, and ADEQ's heightened scrutiny. Projects in Maricopa County, expansions in Pinal County, and growth in Pima County all confront the same reality, water availability determines whether developments proceed or die in permitting.
Our pricing ties to deliverables, approved permits, confirmed water rights, systems engineered for Arizona’s heat and scarcity. Budgets stay predictable because we eliminate scope padding disguised as thoroughness.
Water allocation timing matters more than treatment capacity. Developments in Scottsdale, Mesa, or Chandler can’t break ground until ADWR confirms adequate water supply, making regulatory speed a core design parameter.
Engineers focus on solving ADWR allocation challenges and ADEQ compliance issues instead of attending internal coordination sessions. Streamlined processes yield permit packages that pass review on first submission.
AI handles permit documentation while PEs address water budget calculations, aquifer analysis, and treatment technology selection. Every technical decision carries PE review and stamping.
Clients throughout Arizona need infrastructure that satisfies the strictest water management regulations in the Southwest.
Arizona communities face groundwater pumping limits, declining aquifer levels, and updated ADEQ standards. We engineer expansions within ADWR water budgets, municipal finances, and WIFA funding requirements.
Developers in Phoenix metro, Tucson, Mesa, and Scottsdale must prove 100-year water supply before ADWR approves plats. Our coordination between ADEQ permits and ADWR Certificates of Assured Water Supply delivers regulatory certainty in weeks, not 18 months.
Civil firms without water/wastewater staff, or teams handling multiple Active Management Area projects, rely on us for utility design. We manage ADEQ applications, ADWR submittals, and stamped plans that maintain schedules.
Services designed specifically for Arizona's desert environment and groundwater management requirements.
Collection systems, treatment plants, reuse infrastructure, expansions. One solution, verified costs, ADEQ packages for efficient review. Permits approved in 6-8 weeks.
Wells, storage, distribution, treatment matched to Arizona’s mineralized groundwater. We deliver water supply adequacy demonstrations before ADWR requirements stall projects.
We handle utilities so site development avoids delays. Ideal for firms navigating Active Management Areas, needing capacity expansion, or requiring PE support.
Support from bid through startup. Fast responses prevent heat-related delays. We work with Arizona contractors and understand desert construction challenges.
Challenge Overcome: Discharge permits in Caldwell County near the San Marcos River watershed face intense scrutiny from regional water authorities and environmental advocacy groups. Public hearings attended by Modern Engineering Solutions staff for neighboring discharge permit applications revealed highly contentious 30+ month permitting timelines. The 210E pathway bypassed this opposition entirely, securing approval in just 4 weeks by demonstrating beneficial agricultural reuse. The project’s 2.0 MGD scale, one of the largest 210E authorizations issued to date for MES, proves that flow volume does not limit 210E applicability when industrial components and viable reuse plans are present. The off-site reuse agreement with Circle G Livestock provides long-term disposal certainty while supporting local agricultural operations.
Location: Martindale, Caldwell County, Texas
Authorization Number: 2E-0000348
Time to Permit: 4 weeks
Time Saved vs. Discharge Permit: ~23 months
Project Type: Master-planned mixed-use development combining residential subdivisions, data center operations, and concrete batch plant facilities

Challenge Overcome: Williamson County denied septic permit approval due to platting issues and site constraints that made conventional on-site wastewater treatment infeasible. The 210E authorization bypassed county jurisdiction entirely, allowing the project to proceed under state-level TCEQ oversight with a zero-discharge reclaimed water system. The 4-week approval timeline enabled the developer to maintain construction schedules and avoid costly project delays.
Location: Taylor, Williamson County, Texas
Authorization Number: 2E-0000369
Time to Permit: 4 weeks
Time Saved vs. Discharge Permit: ~23 months
Project Type: Mixed-use business park combining industrial operations with commercial/office facilities

Challenge Overcome: A traditional 1.0 MGD discharge permit in the San Marcos area would have faced significant opposition from environmental groups concerned about impacts to the San Marcos River and Edwards Aquifer recharge zone. Public hearings and third-party referral processes typically extend discharge permits to 30+ months in this region. The 210E authorization completely avoided the contentious discharge permit process by implementing a zero-discharge system. Even with the larger flow volume requiring more detailed technical review, TCEQ approved the authorization in just 10 weeks—21 months faster than a discharge permit. The project’s data center component provided clear industrial justification, while the large-scale on-site irrigation capacity eliminated any surface water discharge concerns.
Location: San Marcos, Hays County, Texas
Authorization Number: 2E-0000365
Time to Permit: 10 weeks
Time Saved vs. Discharge Permit: ~21 months
Project Type: Large-scale mixed-use development combining data center operations, commercial facilities, and supporting infrastructure
Wastewater Profile:
Reuse Strategy:
Challenge Overcome: Williamson County denied the septic permit due to concerns about industrial wastewater constituents and site-specific geological limitations. Traditional on-site disposal was not viable, and a discharge permit would have faced lengthy review and potential opposition. The 210E pathway provided a clean industrial reclaimed water solution in 6 weeks, allowing the facility to commence operations on schedule. The self-contained on-site reuse eliminates any off-site discharge concerns and provides complete operational control.
Location: Taylor, Williamson County, Texas
Authorization Number: 2E-0000358
Time to Permit: 6 weeks
Time Saved vs. Discharge Permit: ~22 months
Project Type: Industrial-only facility with process wastewater and equipment cleaning operations
