Hi all,

I'm looking for good references and information on sizing and designing
gravity fed water systems.

Can you share info on your favorite and most useful references or
experiences on this subject.

particularly pertaining to too much pressure (surge tanks/pressure
breaks/integrating microhydro), warm water issues (hot and thermal
springs), freezing, constant flow, sediment loads and filtering, domestic
use, avoiding air locks.

currently, here's some links and articles I've found.
