Do you collect in a smaller container then pump to these?

No, it drains right off the roof into those. You have to have a roof washer to filter out debris though.

We considered a RWCS for the house we just completed. We have commercial water but it’s hard as nails and frequently has issues. For a 20,000 gal system was around $17,000. The rainwater is soft so does not destroy the pluming fixtures. We can drill a well for $6-8K. Probably won’t do it here. Where wells are more expensive they become cost competitive.

Some systems collect the water from the ac. Not sure how much that adds.

1000 sq/ft roof area and a 1inch rain you would collect 600 gallons and an average sq/ft roof I would say is 2500~sq/ft so that’s 1500 gallons with a 1 inch rain so yes that’s a lot of rain to fill those but 100 gallons a day sounds wayyyyyy high to me. I would say if it was just used for toilets showers and sinks maybe 50 gallons at the highest

I have lived on a 5000 gal rain catch system for 3 years and have never gotten close to emptying it. Single guy though and live on a rock so no landscaping or anything to maintain

I know a few families in the hill country that use water catchment system exclusively for their water. Including my neighbor.

The realtor that we used to buy our house has 5 kids and that's how they get their water. In fact her husband installs them

we may have had the same realtor

a well in edwards county was running 30k-40k last I looked so i catch rain water for the house and haul it from a cistern for troughs and landscape
