  Dover operates a housed slow sand filter that produces approximately 60,000 gallons of finished
water daily. The two 652-foot filter beds were designed with a 50 gallon per minute production rate
and generally require cleaning four to six times per year.
  The city chose this type of filtration because of its simplicity and overall cost effectiveness.
Besides being economical, these filters have a 99.9 percent success rate for removing Giardia
cysts from raw water.
