3-piece rain tank net, adjustable drawstring, leaf and mosquito protection, 80 cm diameter, outdoor garden use

This set of three protective nets for rainwater tanks is designed to meet the health and practical requirements of individuals committed to sustainable water management in France. Each net features a fine, regular mesh structure, a continuous drawstring, and a precise circular cutout with an 80 cm diameter. Made of UV- and weather-resistant polyester, it can be installed in seconds on any open container intended for rainwater collection. Its effectiveness against biological contaminants (mosquito eggs, larvae, fungal spores) and physical contaminants (leaves, flowers, dust) has been validated by field tests conducted in various climatic conditions (Nord-Pas-de-Calais, Nouvelle-Aquitaine, Provence-Alpes-Côte d'Azur). Compliant with best practices for rainwater harvesting recommended by ADEME (the French Agency for Ecological Transition) and local authorities, this device helps reduce the frequency of tank cleaning and limits the risk of insect infestations. It requires no specific maintenance and can remain in place continuously, summer and winter.
