Integrated solutions for stormwater management, technical consulting and engineering, design, construction, monitoring, and operation of advanced systems for the management of stormwater and first flush runoff.
Proper management of stormwater runoff is essential to ensure effective environmental protection and preserve the quality of water resources.
In a regulatory landscape that is often complex and unclear — accompanied by constantly evolving legislation — owners of stormwater discharge systems are exposed to significant sanctions, often without full awareness. At the same time, the sector still relies heavily on standardized solutions that fail to effectively address the specific pollutants actually present in runoff.
At Aquanexa, we believe that every project should be unique. That’s why we carry out in-depth analysis of all defining elements — from legal and regulatory aspects, to anthropogenic activities on impervious surfaces, stormwater collection and treatment methods, and the effects of climate change.
This approach allows us to develop targeted, site-specific solutions, implemented through treatment and purification systems designed to meet high-quality standards and, wherever technically and economically feasible, to promote water reuse in a sustainability framework that goes beyond regulatory compliance.
Our mission is to combine environmental protection, innovation, and value for the client, ensuring the best balance between investment and performance.
Years of experience and our ongoing commitment to R&D have led us to develop proprietary advanced technologies, capable of delivering excellent performance and long-term reliability.
The Aquanexa Team consists of highly qualified professionals with multidisciplinary expertise — engineering, technology, legal, and operational — able to provide comprehensive, tailored support at every stage of the project: from feasibility studies to construction, all the way through to management and maintenance.
Planning Support
Scientific data to support master plans, zoning plans, and urban regeneration projects.
Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP is an environmental planning tool designed to ensure that stormwater runoff does not become a vehicle for contaminants from impervious surfaces or operational areas. Originally required by U.S. environmental regulations (EPA – Clean Water Act), the SWPPP is now adopted as an international best practice in sustainable stormwater management.
Risk Forecasting
Identification of potential issues and optimization of drainage solutions.
Reduced Design and Operational Costs
Informed decisions for more effective and less invasive interventions.
Technical and Regulatory
Compliance Models validated according to national guidelines and European standards.
1D and 2D Modeling
Simulation of rivers, sewer networks, and surface runoff.
Multi-scenario and Multi-risk Analysis
Including extreme weather events, climate change, and future urbanization.
GIS and Topographic Integration
Models built on high-resolution territorial data.
Calibration with Real Data
Based on surveys, monitoring, and back-analysis.
Interactive and Visual Outputs
Thematic maps, runoff curves, video simulations.
Support for SEA and EIA Procedures
Inclusion in strategic environmental assessment (SEA) and environmental impact assessment (EIA) technical documentation.
