Welcome To TheMuskegon County Wastewater
Management System

• A world class land application wastewater
  treatment facility!

2
Background

• opened in 1973
• facility is 17 mi2
• 42,000,000 gallons wastewater/day
• 73 tons of solids/day

3
Wastewater 2 sources

• city sewer toilets go to pipes that lead to the
  WW Treatment
• septic tanks solid waste breaks down by
  bacteria, sludge falls to bottom until tank is
  full, then is taken by trucks to WW Treatment

Step 1

• aeration and mixing
• waste is mixed with giant mixers to add O2 for
  bacteria to eat waste (bioremediation)
• soil filter for odor control filters gases
• mixed from top to bottom

7
Step 2

• aeration and settling
• mixers skim only the surface
• mix to keep O2 for bacteria so they can keep
  breaking down solids
• Solids settle and are cleaned out

8
Step 3

• storage lagoon
• further cleaning and storage
• UV from sun kills bacteria and pathogens
• store billions of gallons of water
• some algae grow in this area
• water is clean enough now, but is overloaded with
  nutrients, would cause eutrophication

9
Step 4

• irrigation and farming
• water is pumped out of lagoons
• giant sprinklers water soybeans, corn or alfalfa
• plants remove nitrogen and phosphorus for food
• pipes underground collect water, bring it to
  Muskegon River
