Water Quality Permitting
Experts that can navigate complex requirements efficiently and effectively.
Water quality regulations can threaten to delay your project or create compliance risks. Integral helps project and program managers—including developers, municipalities, and industrial clients—secure water quality permits efficiently. Our strategic approach anticipates regulatory expectations, streamlines approvals, and produces practical, cost-effective permits. We work closely with client teams to align permitting with project timelines, design, and implementation, ensuring compliance supports operational goals.

National Pollutant Discharge Elimination System (NPDES)
Navigate NPDES requirements with permit applications that demonstrate compliance with regulations while supporting operational flexibility and needs.
Key Capabilities:
- Individual and General Permit Applications
- Waste discharge requirements
- Total maximum daily load (TMDL) and other water quality compliance
- Water quality monitoring and reporting
Stormwater Permitting
Our stormwater permitting services address municipal, industrial, and construction stormwater requirements through comprehensive planning that integrates pollution prevention with site development goals. We design stormwater management strategies that satisfy regulatory NPDES requirements while supporting your project’s infrastructure and operational objectives. We stay ahead of the compliance curve through hands-on project and client interactions, successfully tracking and meeting deadlines and following through on important pollution controls.
Planning Solutions:
- Data management and best management practices solutions
- Stormwater pollution prevention plans and water pollution control plans
- Stormwater capture and reuse planning
- Stormwater management programs
- Illicit discharge detection and elimination
- Non-stormwater discharge prevention and control
- Online NPDES reporting system management (e.g., SMARTS)
- Postconstruction stormwater management program
MS4 and CSO Permit Compliance Monitoring
We design comprehensive municipal separate storm sewer system (MS4) and combined sewer overflow (CSO) compliance programs that meet regulatory requirements through strategic monitoring and data management. Our compliance approach combines receiving water and outfall monitoring with TMDL and special studies implementation support to ensure consistent compliance with water quality standards while avoiding costly penalties.
Compliance Excellence:
- Discharge and receiving water characterization
- Treatment best management practices effectiveness
- Quality assurance/quality control and data validation
- SWAMP- and CEDEN-compliant data reports
- Custom instrumentation
- Emerging contaminants
Water Supply Permitting
Our integrated water supply practice spans planning, rights and feasibility, aquifer storage and recovery (ASR) design, treatment, and regulatory authorization. Our work pairs defensible hydrogeologic modeling with constructible solutions to increase drought resilience and storage reliability. Our team also delivers water supply planning and reuse studies, PFAS risk and mitigation for drinking water systems, and source water/watershed protection planning.
Supply Security:
- Diversify and store supply via ASR and scenario modeling
- Protect sources and manage land use risk
- Harden against contaminants (e.g., PFAS) with assessment and treatment
- Secure compliance and resilience
