Notes/Comments:
Knock on wood, main systems of hab now seem to be running well: potable
water filling went without a hitch today, Wendy's fuel supply is
showing minimal unnecessary loss of diesel, grey water system not
overflowing, toilet working, hot water working. I'm looking forward to
turning on the water heater and taking a brief but revitalizing shower
this evening. :)

Non critical systems on list: macerator wiring, unclog grey water
overflow (from tank 4), wire up solar cells, battery bank.

Requesting info from Gary Fisher on grey water recycling system.
Suspect entire black water drainage field is turning into a giant water
table - which can be seen in dark water under GreenHab floor panels,
dark water in electrical conduit between Hab and GreenHab, plugged
tank 4 overflow, water level in greenhouse (plant section) floor drainage
pipe.
