Rain Water Collection
Since we installed both the garden and the gutters I’ve been looking to get a rainwater catchment system going. The total area of the roof is pretty large so it seems like we should be able to get a fair amount of water collected in order to put a dent in the significant amount of hose water we’re using to keep the drainage-intensive raised beds moist during these summer heatwaves.
Tina’s dad donated a barrel (originally used for soap), which was helpful since the barrels they sell specifically for rain collection seem to run between $75 and $100. This one is a bit small – probably only 40 gallons or so, but since we have about six downspouts around the house, we’ll have plenty of opportunity to install additional systems.
Aside form the barrel, we needed the hardware to get the water into the barrel. There are videos that show you how to use a downspout extension for that purpose, but I wanted to use a purpose-built diverter so that we could easily transition off the catchment system in the winter (to avoid freezing water bursting the barrel). Luckily, there are kits available with all the necessary hardware for a reasonable price.
It only took about 45 minutes to set the whole thing up, including grading out the dirt under the barrel to keep it level. Here’s the finished product:
None of the prospective thunderstorms have materialized here this week, so I can’t give a verdict on how well it works yet, but hopefully we’ll be able to give a more thorough review soon.
