Lunenburg Harbour Water Quality

The Lunenburg Harbour is a working harbour and does not have any designated recreational swimming areas. 

The Wastewater Treatment Plant's federal and provincial operating licenses require an extensive range of testing for treated wastewater before it is released to the harbour.

Please enjoy recreational boating in our harbour - be safe and have fun!

NOT Wanted in our Wastewater System

Toilet sink storm drain header

What you flush, pour down the sink/drain, or dump into a storm sewer doesn’t just disappear. It goes into our wastewater system and into the ocean. 

A wastewater system is designed to treat human waste and grey water only. Problem material in the wastewater system can cause “fatbergs” and clogs, damage household pipes, damage public sewer pipes and equipment, harm marine life and even public health.  

The wastewater system is owned by the residents of Lunenburg. The cost to repair damage from inappropriate material comes back to you, the taxpayer.

For businesses: 

See the Town of Lunenburg’s pdf Bylaw #34 Sewer Discharge (160 KB) for what businesses operating in the Town can and can’t dispose of in the wastewater system.  

For residents and visitors:

Fats, Oil, Grease

NOT 1 grease

Cooking oils • meat fats • dairy products • sauces & dressings • butter & lard

When warm fats are poured down your sink they cool, harden, and can stick to the inside of your sewer pipe. Over time, this buildup causes “fatbergs” that block sewers and catch basins – and costs your tax dollars to repair. You can help!

Never pour grease down the drain. Scrape dishes and cookware - dispose of in municipal compostainer. Thank you.

"Flushable" Wipes

NOT 2 wipes

Personal wipes • baby wipes • cosmetic wipes • cleaning wipes …and even paper towel or luxury tissue!

They may GO down your toilet, but they don’t BREAK down in the sewer. Damage and clogs will result in costly repairs. You can help!

Dispose of wipes in solid waste, or consider not purchasing. Thank you.

Human & Animal Hair

NOT 3 hair

Long hair •  short hair • pet hair/fur or feathers

Hair sticks to oily materials in drains, and then becomes hydro-dynamic so that water doesn’t flush it away. Hair shedding significantly contributes to costly clogged drains and pipes, as well as getting tangled in machinery. You can help! 

Use a hair trap or strainer to catch hair before it goes down your pipes. Clean human and pet hair can go in the green bin. Clogged hair is garbage. Thank you.

Food Scraps

NOT 4 food

Coffee grounds • eggshells • bones • fruit pits & seeds • vegetable peels • pasta & rice

Hard food scraps can cause expensive damage to pipes, blades, and equipment. Soft scraps swell in water to cause clogs.

Never dump food down the drain – garborators are not a solution. Dispose of food prep scraps and leftovers in your municipal green bin. Thank you.

Hazardous Chemicals

NOT 5 paint

Paint & varnish • fuel/oil • solvents • adhesives • pesticides/herbicides • bleach & cleaners

A household drain can seem like a convenient place to get rid of waste, but these kinds of chemicals can cause costly damage to equipment and prove a danger to public health and marine life. You can help!

Never pour hazardous waste down the drain. They should be brought to a disposal depot (like Kaizer Meadow – but check with the depot first, as different depots take different materials – or download the My Enviro-Depot app to search). Consider switching to eco-friendly cleaning products. Thank you.

Discarded Medication

NOT 6 meds

Prescription drugs • over-the-counter drugs • sharps/needles

The toilet (or garbage) can seem like a convenient place to get rid of waste, but some can be a danger to public health and marine life. You can help!

Never flush or throw out medication. Return “dead drugs” to your local pharmacy. Nova Scotia has a province-wide program for the disposal of household pharmaceutical waste.Thank you.

Toilet ≠ Trashcan

NOT 7 garbage

Dental floss • cigarette butts • cotton swabs/balls • diapers • feminine hygiene products • condoms • bandaids • clothing • plastic/paper wrappers & stickers

It’s a toilet – or a storm drain – NOT a trashcan. Garbage dumped down the toilet or sink can cause costly backups and get tangled in machinery. Garbage dumped in a storm sewer can go straight into the ocean. You can help!

Never dispose of garbage down the toilet or a storm drain. Put garbage where it belongs – in your solid waste collection. Thank you.
