Things to
keep in mind
·
Filter needs to be vertical which means there
needs to be a slight hill for the water to fall horizontally into the filter
·
Charcoal, Gravel, and sand are best for
filtering through water
·
Streams need to be cleared of rocks near the
filter
·
Motors need to propel water into the filter so
it quickens the filtration process
·
A v shape will be used in front of the filter in
order for all water to go to the filter
