Wind
Pump
<>  When Dathan Herulus arrives at the Ice Dragon
Inn, he notices a wind pump that is responsible for providing the inn
with fresh water. He's right about this. Although
Dathan thinks that the pump's upper tank stores water, it does
not. The pump's upper tank stores air, which is used to
pressurize a large water tank buried below the frost line to
protect it from low winter temperatures. (When the fleeing
Tamarians broke open the lower air valve, they rendered the pump
useless.) The AirLift Technologies and Bowjon companies
build wind powered water pumps that works on this principle. The
only difference between these systems and the one installed at the
Ice Dragon Inn relates to the position of the water storage tank.

This is an
older, mechanical technology that will probably be familiar to readers
living in the western U.S.:
Rainwater Collection
Though Tamaria is described as a land of
high mountains, glaciers, lakes, rivers and streams, certain geographic
situations and microclimates very careful water management. Among
the strategies for dealing with problems of this kind, rooftops in
places like Marvic are made with metal to facilitate the collection of
rainwater and melting snow. Guttering is designed to collect the
diffuse rainwater and channel it into a filtration system. After
this, the water is stored for later use.

This system uses plastic barrels linked together by tubing to create
a manifold-style storage system.
The filter is created by
filling the bottom of a drum with gravel to a depth of about 9
inches. Over this about 3 inches of coarse sand or washed
charcoal would be placed. The downpipe from the roof would
contain an extra length that extends lower than the filter. This
serves as a way of allowing dirt on the rooftop to wash off before any
collection takes place. This can later be drained.
A rotary pump, installed
in the final storage bin, allows house water to be pressurized.
Multrum
Toilet
Human waste is not a pleasant subject to
discuss,
but as it is a necessary part of life, avoiding the subject detracts
from the realism of a story's narrative. Of all the technologies
available to deal with this problem, composting toilets are the most
environmentally friendly for several reasons.
- Well composted human
waste eliminates the
spread of dangerous pathogens, such as typhus and cholera.
- Composted human waste
closes the nutrient
cycle by returning valuable minerals and chemistry to the
soil, utilizing friendly bacteria that have been doing this since
life began.
- Composting toilets aid
in water
conservation.
- Odors do not develop
in a well designed
aerobic system.
- Multrum toilets are
often less expensive to
install and maintain than traditional sewage treatments.
-
These systems remain effective in cold
weather, provided the decomposition tank is kept warm.

The way they work involves creating an
environment that is remote from the toilet itself, where aerobic
bacteria can successfully break down waste. This system often
contains a rotating drum to mix the contents and functions like a tiny
sewage treatment plant. A gravity, micro flush toilet's outlet
leads into an insulated chamber where air is circulated. In
this bacteria friendly environment, water evaporates and waste is
rapidly decomposed. After several months (or even years,
depending on usage) the fully composted waste can be safely removed and
re-applied to soil.
Aquaponics
The vast majority of
protein
consumed by Tamarians comes from fish. Not every locale is
suitable for catching wild species, and though Tamaria is a land where
glacier-fed rivers are abundant, in some places the Tamarian people are
completely dependent on rainfall. As a means of conserving water
and preserving natural fish stocks, the Tamarians utilize aquaponic
methods for raising fish and vegetables. It's a technique that
mimics the natural processes found in rivers and lakes, whereby the
cycle of nutrient and waste is closed, enabling people to supply their
protein and vegetable needs within a confined space, using minimal
water and energy.

In essence, fish grow in the
lower tank. Their wastes settle into a gravel bed, and water from
there is pumped up to a biofilter pipe where microorganisms feed on the
waste and transform it into plant food. Vegetables, grown without
soil, using hydroponic techniques, uptake the effluent for their needs
and by doing so, clean the water. The water drips back into the
fish tank. Most of these systems utilize species like tilapia,
which are vegetarian and eat plant scraps from the vegetables.
People benefit from eating the fish and vegetables. Of course,
the Tamarians would be using metal tanks and pipes for this!
There's a LOT of information
about this technique available on the web. I took this image from
a .pdf document composed by Travis W. Hughey. It's a step-by-step
manual detailing how this system is constructed, and it can be found
