St. Lawrence sewage dump: 7 tips to limit your impact

Close to half a million people in the island of Montreal, plus thousands of workers coming into the cityfrom the suburbs, will have their wastewater directly dumped into the St. Lawrence River, if aplan to dispose of eightbillion litres of raw sewage goes ahead.

But each person and business has the power to limit ifmodestlythe amount of pollutants going into the river. Here are some tips to do just thatfromAlexandre Joly, general director of Comit ZIP Ville-Marie, an advocacy group for the St. Lawrence, and Simon Octeau of the Regroupement des co-quartiers.

Don't throw garbage into toilets and sinks

Some people have developed the habit of throwing all sorts of waste down the toilets, like cotton swabs, dental floss, condoms and tampons. Most of these products should go in the trash.

Expired drugs should not be flushed down the toilets, either. These can be dropped at pharmacies, whichdispose of them properly. Paintbrushes shouldn't be washed in the sink or the tub, either. Hazardous household waste can be discarded at ecocentres.

Cooking grease is often poured down the sinks, but this can clog sewer lines. Instead,it should be left to cool, then tossed in the garbage or compost bin. As for food, avoid using the sink's garbage disposal between Oct. 18 and 25.

Don't use storm drains as garbage

Garbage like cigarette butts, gum, plastic wrappers and dead leaves should never be thrown down sewage drainsnot during the sewage dump days, not ever.

Also, be careful around these drains. Water treatment plants the world over find all sorts of useful things in the wastewater, like cellphones, glasses and dentures. And between Oct. 18 and 25,these will all go into the river.

Reduce water use

All the water from sinks, showers and toilets will go straight to the river. Simple gestures like turning off the shower when soaping up or the faucet when brushing teeth can reduce the total volume dumped.

Dedicated residents can go furtherand reuse water. For example, keeping the water used to wash vegetables in a bowl, and use it to wash your hands later.

Stopping leaks can also save hundreds of litres of water a day.

Those who canmight also consider showering every two days during the dumping period, or taking showers instead of baths, which use up twice as much water.

Optimise flushing

Montreal's plan to dump the raw sewage has been baptized #FlushGate on social networks. During the dumping days, the waste of half a million people will join the fish in the river. One simple gesture to limit the damage is to refrain from flushing after each and every trip to the loo.

Another technique to reduce water usageis placing a filled water bottle in the toilet tank to reduce the volume of water in the tank.

Limit washing

Avoid washing your car between Oct. 18 and 25. The dirty water will be dumped into the river. Likewise, you can plan to not do any laundry between those days.

Don't empty the pool

It would be better to empty the pool during Thanksgiving weekend. Otherwise, hundreds of litres of chlorinated water will go into the river.

Use biodegradable products

Those wishing to reduce their use of pollutants can use biodegradable cleaning products. These can be identified by labels in the back. Look for a logo that says "OECD test 301."They are reportedly better for the user's health, as well.
