Art Ludwig's Water Storage: Tanks, Cisterns, Aquifers, and Ponds For Domestic Supply, Fire and Emergency Use Includes How to Make Ferrocement Water Tanks. And Art Ludwig's Create an Oasis with Greywater. Something about the combination of excessive detail for the uninformed (that would be me) and the design, which indulges heavily in the less classical fonts, is incredibly calming. Lots of aphorism possibilities. It is best, for instance, to have a black plastic tank that is painted white so it will be both cool and dark inside.
