Stormwater





What is stormwater?

Stormwater is the rain and melted snow that flows from local properties onto the street and into storm drains. It eventually ends up in Ontario’s lakes. Stormwater infrastructure protects our water quality and helps lower the risk of flooding.

In Middlesex Centre, our stormwater infrastructure includes stormwater ponds, storm sewers, catch basins, maintenance holes, oil grit separators, culverts and municipal drains.

Climate change, aging infrastructure, new residential development and other factors put pressure on our stormwater infrastructure. To protect local property and the environment, we need to invest more money in stormwater infrastructure.




What is Stormwater Management?


Stormwater management involves storing and directing stormwater runoff in urbanized areas to control flooding, erosion and water quality. This practice protects communities, municipal infrastructure (like roads, sidewalks and trails) and local waterways. The objective of stormwater management is to slow the release of stormwater runoff into natural systems.

One way of managing stormwater runoff is through the use of stormwater ponds. Stormwater ponds can be ‘dry’‐ filling up during a storm, or ‘wet’ - having a permanent pool of water. These ponds are designed to hold back stormwater and release it slowly to natural waterways. Wet ponds also allow sediment to settle to the bottom of the pond instead of traveling to a local stream. Stormwater ponds do require maintenance to keep them working properly, such as sediment removal or cleaning of catch basins. Sometimes older ponds need to be replaced with newer, more efficient designs.


Why is Stormwater Management Important?

Without stormwater management, runoff from urbanized areas would flood communities and roads, cause stream erosion and destroy aquatic habitat.  Lakes and local streams also suffer from runoff, Stormwater that rushes uncontrolled from urban pavements causes streams to rise faster and more dangerously than those in rural areas. The force of the water during rain events scours stream bottoms, erodes banks, harms fish habitat and increases pollutants such as phosphorus and heavy metals. Stormwater picks up dirt, oil, grease, road salt, fertilizers, pesticides and bacteria from urbanized areas. During its journey over pavements, stormwater also becomes warmer which is harmful to fish

Stormwater management is required to release runoff into natural waterways slowly, imitating the water cycle before urbanization. Stormwater ponds are also important because they provide an opportunity for sediment (and pollutants attached to the sediment) to become trapped in the pond bottom, rather than moving into the local streams.


What is Middlesex Centre’s Role in Managing Stormwater?

The Municipality of Middlesex Centre is responsible for planning adequate stormwater control for existing and new communities along with operating and maintaining these systems.  The Municipality must ensure the stormwater system is operating in accordance with various acts, regulations and approvals provided by federal, provincial and local authorities


What is the Stormwater Management Rate?

A comprehensive review completed in early 2016 found that Middlesex Centre needed an equitable, dedicated and stable source of funding for stormwater infrastructure. The stormwater charge will allow us to invest in this infrastructure now so that it will be better able to adapt to challenges today and over the long term.

The Stormwater Management Rate is a dedicated source of funding for our stormwater infrastructure. It is a monthly charge applied to all properties situated within one of the Municipality’s settlement urban growth boundaries as defined by the Official Plan (refer to map schedules at end of Official Plan)

All properties located in the settlement areas, regardless of the type, will pay $14.88 per month for stormwater management services. Properties above 0.4 hectares (1 acre) in area, will contribute an additional $42.18 per hectare per month (prorated).

What is a Municipal Drain?

Municipal Drains are created under the authority of the Ontario Drainage Act. There is a legal process in place for the creation and maintenance of these drainage systems, and by law, costs for the creation and maintenance are assessed to the contributing land owners. Municipal Drains are typically constructed to service rural or agricultural areas. 

Ways You Can Help


Everyone can help reduce the amount of stormwater runoff. Try these tips to reduce your stormwater ‘footprint’, lower your water bill, and conserve water:
  • Use a car wash instead of your driveway to wash your car. This will decrease the mixture of wash water and sediment entering storm sewers.
  • Clean up animal waste, grass clippings and fallen leaves from your property regularly.
  • Be careful to not over‐fertilize your lawn as excess nutrients can enter the stormwater system.
  • Have your car fixed if it is leaking fluid. Oil and other vehicle fluids can be very harmful to fish and wildlife reliant on our streams, rivers and lakes.
  • Use rain barrels to capture roof runoff and use this water on your lawn and gardens.
  • Disconnect your roof downspout if it is connected to a storm sewer. You can either connect it to a rain barrel or have it directed onto your lawn. Use water from rain barrels to water your lawn or gardens.
  • Manage your use of road salt and sand in the winter. During snow melt periods, salt and sand will enter the storm sewer system and can have negative impacts downstream.
  • Dispose of household hazardous waste properly, not down a storm drain.
  • Choose plants that are drought tolerant and do not need to be watered as often.
  • Check your sprinkler system for leaks and ensure you are only watering your lawn on days and times allowed. The best times to water your lawn and garden are in the early morning or late evening.

Delaware Community Settlement Area Stormwater Master Plan


Middlesex Centre Settlement Area Stormwater Master Plan

The Municipality of Middlesex Centre is proposing to undertake a storm drainage study for each of its settlement areas (Arva, Birr, Ballymote, Coldstream, Denfield, Ilderton, Kilworth, Komoka, Melrose, and Poplar Hill, Bryanston and Lobo) following the Master Planning Process outlined under a Class Municipal Environmental Assessment.  The study is to incorporate the key principles of environmental assessment planning including public and agency consultation in accordance with the requirements of a Class EA.

The Master Plan is intended to provide a strategy for the implementation or enhancement of a storm drainage system for the aforementioned settlement areas including:
  • an analysis of the existing system components resulting in recommendations for improvements and modifications to the existing system; 
  • and the identification of preferred solutions for the servicing of future growth and development within the community
