Here's a move-by-phase guidebook describing what happens at each phase with the treatment process And exactly how pollutants are taken out that can help retain our waterways clean up. This info is courtesy with the Larger Vancouver Regional District.

As natural and organic make a difference decays, it uses up oxygen. Aeration replenishes the oxygen.

Grit is pumped out on the tanks and brought to landfills.
