Here's the best water conservation tip.  Repair or replace at risk water piping or water distribution systems.  No amount of water conservation measures can overcome a leaking or burst domestic water pipe.  If you have a home built before 1965, and your water distribution system has not been replaced,  it is likely to be aged galvanized steel pipe.  That's the exact system that could deplete all your conservation efforts.  In this extended dry spell initiate real conservation.  Have your water distribtution system inspected by a real plumber.  Then, if necessary, replace and CONSERVE!
