Gazillions of people live in deserts or arid regions ~ a large lawn leaf bag used once a year for 10 minutes will probably provide all the protection that market will ever need.
There’s a lot more rain than that in the desert. Then of course there’s “after the rain”, puddles can stick around a long time. The real question for this is what’s wrong with aluminum piping, light, cheap, strong, has no problem with rain or really any weather.
