How to use the Phantom Water Pump
What is a Phantom Water Pump?
Answer: It's a single water-pump that supplies enough water to
water your entire city. If you look in the graph window, you should
see your water level at 100% at all times.
How do I get a Phantom Water Pump?
Answer: Place one water-pump that is:
See an example of a Phantom Water Pump
from Jerry Moore's city MoleVille.
Not next to any buildings. Make sure that no buildings will be built
next to it by creating a de-zoned area 3x3 tiles in size. Place the
pump in the center tile.
Not connected by any underground water-pipes.
Some believe in the Phantom Water Pump and some don't.
Some believe that just because the graph window shows 100% water
doesn't mean your city is 100% watered. They believe the graph doesn't
show how much your city is watered, it shows how much water is not being
used. If you have a single water pump not connected by any pipes, then
100% of it's water is not being used.
Phantom vs Watered: A watered-tile is nearly double the value of a
dry tile. That's the only difference. Now the question you
have to ask yourself is "does land-value really matter?" Should you
waste valuable land to build water-pumps or use that land instead
to build other things?

Over the weekend I ran some additional tests on the SC2K water model. I
"pre-zoned" a city 64 tiles wide by 64 tiles high and pre-placed all the
essential services. The zoning was roughly 50% residential, 30% commercial
and 20% industrial. The first scenario was with no water pumps or pipes. I
then let the city run for 20 years, placed it on pause and measured all the
essential values. I ran a 2nd scenario for the same time period with the
phantom water pump, a 3rd scenario with 1 tile pumps surrounded by water
outside of this 64 x 64 tile grid and a 4th scenario with 1 tile water
surrounded by pumps. In all 4 scenarios, population growth and annual tax
revenue generated was essentially the same, with the only variable showing
any significant change being land value. The phantom pump and no pump
produced the lowest land values, water surrounded by pumps was next and
pumps surrounded by water was highest. I initially ran these tests on the
DOS version 1.01 software. Subsequent tests on DOS version 1.0, version 1.1
and Windows produced very similar results. The only conclusion I can draw
from this is that water has no impact on population growth or revenue and
that using available building space for more zones instead of pumps allows
for larger populations.

I concluded much the same. I did notice that the phantom pump is no
different than no pump at all, because it's not connected to the water
grid. All the phantom pump does is show the water % in the graph as 100.
This is because the water model shows this data as the amount of water NOT
being used. If it says 100, then 100% of the pumps' water is not being
used. If it goes to 80, then 80% of the pumps' output is not being used.
When it hits 0, then none of it is being unused; all of it is eaten up by
Secondly, as you mention, value seems to be the only affected variable. On
average, value increases by up to 70% if a tile or city is fully-watered.
So, if you plug in a water system to a dry city with a value of 60, you'll
end up with a city value of about 102. Unfortunatly, city value seems to
have little effect on growth, density, or revenue. I'd say it's a flaw in
the design, although it doesn't really hurt the game any.
