Municipal Water Supply, Use &
Sewage Treatment
1. Brantford’s water source is the Grand River.
2. Water Treatment Plant = Waterworks Park.
3. Water use = residential, commercial, industry.
4. Waste water (what goes down the drain) drains into the
municipal sewer system and goes to the sewage
treatment plant. Rainwater drains into the storm sewer
system and goes directly back into the river.
5. Sewage Treatment = Mohawk Sewage Treatment Plant.

Primary Treatment – Screening and primary
settling to remove garbage, large solids and
sediment.
Secondary Treatment – Uses biological
processes in which bacteria and other
microorganisms break down most of the dissolved
organic waste (aeration tank digestion, sludge tank
digestion = stomach).
Tertiary Treatment – chemical treatment to
remove phosphates, nitrates, harmful bacteria and
other contaminents, before cleaned water goes
back into river.
Concentrated Sludge – pumped to lagoon for
storage, then trucked to landfill or farmers
(fertilizer).
Brantford treats 100 Wayne
Gretzky swimming pools of
waste water per day!
Garbage – To the Landfill

Toronto Tap vs Bottled Water
Below is a side-by-side comparison of the federal regulation of bottled water under
the Food and Drug Act and Ontario’s regulation of Greater Toronto’s water under
the Safe Drinking Water Act.

Facts about the Pacific Garbage Patch
1. The size of foul field of Trash is 2 times the size of Texas.
2. It is said 1/5th of junk trapped in the “garbage patch” comes from ship dumping
and the rest of the trash comes from human land trash.
3. Environmental researchers believe 90% of the trash in the ocean dump is from
plastic, which is not bio-degradable.
4. Some environmentalists say there is 3.5 million tons of waste swirling in the
Pacific vortex near the beautiful Hawaiian Islands.
5. Thousands of birds and sea-life creatures are dying from eating plastic particles
in this huge debris field, because they can not digest the plastic and it
dehydrates them or stops their digestive system from functioning.
6. Some of the tiny plastic bits
pass into the living systems of
marine life and travel up the food
chain until it lands on your dinner
plate or in your fish sandwich!
And, yikes…. Gulp…. you have
eaten residual plastic! Perhaps a
piece of your plastic grocery bag,
water bottle, used condom or
plastic chips bag ends up in your
stomach.
