Optimal maintenance of constructed wetlands using an environmental decision support system

Area of Science:

• Environmental Engineering
• Water Treatment Technologies

Background:

• Constructed wetlands (CWs) are cost-effective wastewater treatment solutions for small communities.
• Proper design, construction, operation, and maintenance are crucial for CW effectiveness.
• Variability in CW maintenance practices necessitates standardized guidance.

Purpose of the Study:

• To develop an Environmental Decision Support System (EDSS) for Catalonia's constructed wetlands.
• To provide tailored monitoring and maintenance guidelines based on individual CW characteristics.
• To ensure the long-term reliability and performance of constructed wetlands.

Main Methods:

• A five-step methodology was employed: problem analysis, data collection, model selection, implementation, and validation.
• The EDSS was designed to adapt recommendations to specific constructed wetland features.
• The system integrates data and knowledge for informed decision-making.

Main Results:

• The developed EDSS offers customized monitoring and maintenance recommendations.
• The system addresses the need for standardized yet adaptable CW management strategies.
• Examples of EDSS outputs demonstrate its practical application.

Conclusions:

• The EDSS enhances the management of constructed wetlands by providing site-specific guidance.
• This approach supports the sustainable operation of artificial wastewater treatment systems.
• The EDSS is a valuable tool for water agencies managing decentralized treatment infrastructure.
