We ( www.rainbrothers.com )specialize in rainwater harvesting systems used for drinking water. This is an overview of a residential project here in Ohio. The site had just been inspected by the Health Department, so we had all our trenches open and thought it would be a good opportunity to put together a video for reference.
It is important to note that we typically do not make hard connections to the tank (either with the pump supply line or the tank inlet and outlet) until the tank has been backfilled and compacted to the levels of the pipe connections. However, this particular county health department inspector requested that the pit be exposed and the connections be made for the inspection. Also, you’ll see that there is water in the pit under the tank. This is groundwater that seeped in during excavation…. It was not put there by us and, no, we don’t have a cracked or leaking tank.
This is just a quick video to cover the basics of my water storage. Nothing to special just 4, 55 gallon drums stored in a stack.
