Hi sir nice vídeo, in Brazil we have "barreiro de trincheira" is one sand box but for water hehe, it can be nice befor or after your nice swale, the barreiro de trincheira is one retangular pond for store water, no fish, no infiltration. is about 16x 5 x 5m its a lot water. (400m³).

Scandalous

with out rain. It will be depleted. fast or slow. we like dramatic fast change.

In winter, store wat is given. In summer think about what you need from winter. Swales are such a good system for hilly terrains like the Greek islands.

with all the water in the oceans and according to them the water is rising why not use it then ?? desalination is better and cheaper than trying to force feed everyone nonsense garbage about the global warming!!

Sustainable water catchment the system, swales artificial wetland for filtration system and sustainability-based water infrastructure development

The Greedy and ignorant elite are consuming the planet.

Hoarding Inequality To allay this.
