Description of the project
Summary
We offer residents autonomous rainwater collection tanks for allotment gardens. Rainwater is collected by a canopy and stored in a polyethylene cistern. The water is used in situ for watering plants, gardens and vegetable gardens. This device is installed on natural ground and does not require foundation. Large pitted support plates provide stability in high winds. An overflow pipe is integrated into the tank to evacuate excess water. The system purges itself automatically in the event of severe frost. The valve can be equipped with a padlock to control water usage. Benches are arranged on both sides to create meeting spots in the shade.
Key objectives for sustainability
The demand for access to allotment gardens is high. To meet this demand near cities, we have designed a device that complements the drinking water network for irrigation. Thus, cities can quickly deploy new gardens with our PLUV solution, and then start adduction works as a second step.
Durability in terms of construction
For reasons of robustness, this tank is designed in galvanized steel.
Its low-tech design does not require any sophisticated technology. Once filled, the distribution is done simply by gravity.
It is equipped with an anti-freeze device to prevent any damage to the tank in the event of low temperatures. It is weatherproofed by an approved control laboratory.
Key objectives for aesthetics and quality
Its form follows its function. Its LEM (lunar excursion module) silhouette derives from safety standards. The rainwater funnel-collector at the top requires substantial legs to ensure good stability. A vertical cable system connecting the funnel to the legs provides support for vertically vegetating it with climbing plants.
Key objectives for inclusion
This rainwater sharing equipment is installed in the allotment gardens, accessible to all populations, disabled included.
Two benches are attached to the legs to provide 8 seats and thus facilitate exchanges between gardeners. Once vegetated, in summer, it provides a point of shade and freshness for users.
Results in relation to category
Depending on the rainfall and the use made of it, this tank has the capacity, in Angers, where it is installed, to collect more than 7000 liters of water per year.
It also has the educational ability to reveal the state of water reserves.
How Citizens benefit
This project was developed thanks to a participatory budget, voted by the citizens of the City of Angers. The gardeners wanted us to provide them with a simple and effective additional watering solution while providing them with a place to exchange.
Innovative character
The allotment gardens are equipped with various water distribution solutions:
- adduction by the water network
- garden sheds and their roofs to collect rainwater
Our solution complements existing solutions by hybridizing the rainwater collection-storage function with a central statutory function promoting exchanges between gardeners.
