We have an 1880's little farmhouse in MI, with an underground cistern on the south side. It was probably put in at the same time as the house, because the basement wall is right next to the cistern. Basement is poured cement, cistern is a brick cylinder lined with plaster. I have cleaned it out and would like to repair/recover the lining. It's generally in pretty good shape, with some cracks (largest about 1/2in) and a couple of places where the plaster fell off the bricks (largest patch about basketball size). What sort of plaster can/should I use ? It needs to hold water obviously. I've looked at lining it with plastic/vinyl type stuff, but that will cost >$450. We'll use the water for household stuff when the power is out and the garden. Any suggestions/advice is welcomed.
