Flood Preparedness

Over the past five years Hamilton has experienced a lot of rain. The rain storms last longer, are more intense and occur more frequency than in previous years. The City of Hamilton is committed to assessing, analyzing and implementing storm water management improvements to deal with heavy rain. 

Flood prevention tips

There are many things you can do to avoid or minimize flooding damages.

Year round tips

Here are things you can do throughout the year to prevent or minimize flooding and associated damage.

  • Ensure your sewer laterals, the pipes from your house to the sewage line, are functioning properly.
  • Seal cracks in your basement floor and foundation walls.
  • Keep your eavestroughs clean so they can direct water away from your house. When they are not maintained, rainwater is more likely to enter your home through cracks in your foundation.
  • Minimize points of entry for overland flooding such as window wells and window well covers.
  • When landscaping, ensure the grade of your lot flows away from your home.
  • Use permeable surfaces for driveways and walkways so that water can soak into the ground.
  • Ensure catch basins on the road near your property are clean. Keep leaves and yard waste from piling up in the roadway, ditches and sidewalks. They can clog the sewer system.
  • Do not store items on the floor in your basement. Install shelves several feet off the floor to store items.
  • Do not sit appliances, furnaces and water heaters directly on the floor in your basement. If possible, they should be set on a stable platform or on appropriate material such as cement blocks.
  • Install electrical outlets and electrical panels higher than a projected flood level.
  • Do not run drywall all the way to the floor in a finished basement; use material such as tile or linoleum running up the wall about one foot high to guard against water damage.
  • Consider the installation of protective plumbing devices such as backwater valves or sump pumps.
  • Do not pour grease down the sink and into the sewer system. The grease may stick to the sides of your sewer pipe or the City’s sewer pipe. Over time, this could build up and create blockages.
  • Consider disconnecting downspouts from the sewer system. Make sure neighbouring properties will not be adversely affected.
  • Maintain the swale on your property. The swale is usually located on the property line between properties. A swale is a shallow trough-like depression that carries water during rainstorms or snow melts.
  • Create an inventory of your possessions with photographic and/or video documentation in case you need to submit an insurance claim for water damage.

Here are things you can do in the spring and summer to prevent or minimize flooding and associated damage.

  • Make sure the grading allows water to flow away from your home when landscaping your property.
  • Minimize the amount of hard surface such as cement, driveways and walkways on your property. Rainfall should be absorbed into the ground. Hard surfaces make the water flow in the most natural direction.
  • Plant gardens, plant material and trees to absorb water.
  • Use rain barrels to direct water away from your home and the sewer system. Set up your barrel so rain from your eavestrough goes into it. Run a hose from the rain barrel to water your garden.
  • Install window well covers to keep window wells free from debris, which can clog drains and cause basement flooding.

Here are things you can do in the fall to prevent or minimize flooding and associated damage.

  • Clean up leaves and yard waste from the roadway, ditches or sidewalks. This prevents clogged catch basins and allows the free flow of water. You can put out an unlimited amount of yard waste on your pick up day every week.
  • Clean up litter to prevent blockages in the sewer system.
  • If you see larger debris on the street, call 905-546-2489 to have it removed.
  • Clear leaves from your eavestroughs. When your eavestroughs are blocked, the rain will pour over the edges landing on the ground next to your home. If you have cracks in the cement wall of your basement or problems with your weeping tile, this water could enter your home.

Here are things you can do in the winter to prevent or minimize flooding and associated damage.

  • Keep catch basins clear and uncover fire hydrants near your home.
  • When clearing your driveway, move snow toward the side of your property that the plow finishes with so less snow accumulates across the driveway when the plow passes.

Many homes in Hamilton have a sump pump installed. The sump pump plays an important role in flood prevention and keeping water out of your basement. A sump pump is typically a small pump used to help keep the area under your home dry and to prevent it from flooding by removing excess water that has accumulated. The sump basin which should be in the lowest part of your basement or crawlspace is where the unwanted or excess water collects. When the water level gets too high the sump pump is activated and begins pumping water out of the basin. The water is pumped outside and away from your home, so the basement stays dry.

It is important to maintain and test your sump pump on a regular basis to ensure that it will work properly when needed.

To ensure the pump is working properly perform this three-step test:

  1. Check to make sure that there is power running to the sump pump.
  2. Pour enough water into the sump pit for the pump to begin working.
  3. Check the outside pipe to ensure that water is flowing from the discharge line outside your home and away from your foundation, as well as, your neighbour’s foundation.

Sump pumps have a lifespan of approximately 10 years, which can vary based on how often it is working, the quality of the water (dirt and grit) and the quality of the pump itself. Different manufacturers have different recommendations for testing and maintaining your sump pump. Please follow the recommendations provided by the manufacturer. There are some steps that you can do to help your sump pump run effectively. If your pump is operating during freezing weather, it is best to disconnect outside hoses prior to winter. This will help blockages from forming in the hose which could damage the sump pump. Always make sure that the water discharges away from your home. If water from your sump hose discharges too close to your foundation, the water may end up back in your system.

*Maintenance should be done by a qualified technician.
