Main rain water holding tank and overflow tank painted white. Water pump parts selected, drainage pipe primed, base plates primed, and another piece of CN container cut for the water pump platform. Ordered a 4' x 8' sheet of PVC foam board which will be cut and ready for me to pick up in a few days.
A model aircraft carburetor makes for a nice-looking geothermal wellhead.
Added pumps and rainwater to the reservoir. Realistic water layer should cure clear by tomorrow.
