Canal-Safe Exterior Cleaning in Cape Coral: Runoff and Your Canal
Short answer: wash water and cleaning solution that run into storm drains or straight off a seawall can reach Cape Coral’s canals. Canal-safe exterior cleaning means wetting and rinsing plants, keeping cleaning solution out of drains and the water, checking runoff before starting, and using containment where required.

Why Does Runoff Matter So Much in Cape Coral?
Runoff matters in Cape Coral because the city has more than 400 miles of canals, and the water from streets and yards flows toward them. The City of Cape Coral warns that chemicals carried by stormwater runoff pollute the canals.
On a canal home, the backyard, pool deck and seawall drain almost directly into the water. On other streets, wash water that reaches the storm drain out front can end up in a canal too.
Is Pressure Washing Bad for Canals?
It depends on how it’s done. Rinsing plain dirt into a lawn, where it soaks in, is low risk. The problems start when cleaning solution, oil, paint chips or heavy grime are sent down a storm drain or over the seawall into the canal.
| Lower-risk practice | Higher-risk practice |
|---|---|
| Rinse water soaks into the lawn | Rinse water runs down the driveway into the street drain |
| Cleaning solution kept on the surface being cleaned | Solution sprayed or rinsed over the seawall |
| Plants wet down and rinsed | Plants left dry and unrinsed |
| Debris swept up first | Debris and grime washed into drains |
How Do We Keep Runoff Out of the Canal?
We keep runoff out of the canal by checking drainage before we start and controlling where the water goes: plants are wet down and rinsed, cleaning solution is kept off plants and out of drains, and containment is used where required. On canal homes we take extra care near seawalls and docks, where water drains straight into the canal.

- Sweep up leaves, dirt and debris before you wash
