Stormwater & Retention Pond Aeration and Fountains
Aeration systems, circulation and display fountains for stormwater and retention ponds across Canada - ETL listed equipment with the spec documentation municipal and developer projects require.
A retention pond is infrastructure, not a water feature.
It was dug to hold runoff, and it collects everything the runoff carries — lawn fertiliser, road sediment, whatever washes off the roofs. Then it stratifies, goes still, and starts producing algae, odour and muck. A fountain will make it look better from the road. Circulation and oxygen are what actually stop it behaving like a stagnant lake, and on most ponds the right answer is one piece of equipment doing both jobs — provided somebody sizes it against the water instead of the sight line.
We size the system before we quote it — against your actual surface area, average depth and distance to power. Free, and no obligation.
Paperwork a procurement file will accept — exact models, cord lengths, control panels and delivered pricing in CAD, written up for a municipal tender, a developer's budget or a board vote.
We service what we sell. Authorized Kasco dealer and certified repair centre in Markham, with genuine parts and replacement motors in stock.

Most suppliers in this category send you to a contact page and go quiet. Here is exactly what we do instead.
STEP 01
You tell us about the pond
Surface area, rough average depth, and how far the water sits from power. If the as-built drawings are long gone, say so — photos and a satellite screenshot are usually enough for us to work from.
STEP 02
We size the system, free
We match horsepower and approach to your actual pond, check what the electrical service can carry, and flag anything that causes trouble later — spray drifting onto a path, or a cable run that won't reach the shore.
STEP 03
You get a real quote in one business day
Exact models, cord lengths, control panels and delivered pricing in CAD, written so it can go straight into a procurement file, a capital budget or a board package.
The cost of leaving it
Why engineered ponds behave like neglected lakes
A retention or detention pond does its hydraulic job whether or not anyone maintains it, which is how it ends up unmanaged until the complaints start. The mechanism underneath is always the same: nutrients in, no circulation, no oxygen at the bottom.
The runoff is the fuel
Every storm delivers nutrient-rich water off roads, roofs and fertilised lawns. Still, warm, shallow water plus a steady nutrient load is the exact condition a summer algae bloom needs.
Odour and mosquitoes reach the neighbours
Once a pond stratifies, the bottom goes anaerobic and starts to smell. Adjacent residents notice that long before anyone in the office does, and their complaints are what usually funds the fix.
Muck settles and stays
Organic sediment accumulates on the bottom year after year. Continuous circulation and oxygen suppress algae, cut the odour and speed up the breakdown of that organic material rather than letting it build.
How we size it
Three facts decide almost everything
Have these ready and we can usually specify a system the same day. Don't have them? Send photos and we'll work it out from there.
Surface area
Roughly how big the water is, in acres or in feet by feet. This sets horsepower and how many units the pond needs.
Average depth
Decides whether a surface unit or bottom diffused aeration is the right approach, and how much of the water column you will actually turn over.
Distance to power
From the water's edge to the nearest panel, and what service is there — 120V, 240V or three-phase. This sets cable length and panel spec.
Two things separate a stormwater pond from an ornamental one. The first is documentation: Kasco surface aerators are independently tested at up to 3.0 lbs of oxygen per horsepower-hour (Auburn University) and are ETL listed to UL and CSA standards, which is the certification paperwork municipal and institutional projects ask for. The second is electrical reality. Single-phase 120V and 240V units run up to 5 HP — the 3.1 and 5.1 models deliver 3 to 5 HP on single-phase 240V where three-phase service isn't available — while the true three-phase 3.3 and 5.3 models ship with a CA-3235 control panel. On a deep pond, or a site where nobody wants electrical equipment sitting in the water, the compressor stays onshore in a cabinet and the pond is aerated from the bottom up. Timer, thermostat and lighting controls automate the run schedule so facilities staff aren't managing the equipment day to day.
Fountain Depot carries 50+ years of fountain installation and service experience through Fountain Place, including commercial and condominium water features across the Greater Toronto Area.

Ships across Canada, typically 3 to 10 business days, and GTA sites are serviced directly from Markham. Recent work is in our project gallery.
Get the pond off the complaint list
Send us the surface area, the average depth and where the power is. We'll size the aeration properly and come back with costed options you can put in front of a council, a board or a client. Free, and usually within one business day.
If the pond suffers algae blooms, odours or resident complaints, yes. Aeration treats the stagnation and oxygen depletion that cause all three.
It also reduces long-term sediment and muck accumulation, which is what drives dredging costs later.
Fountain or aerator for a retention pond?
Choose a surface aerator or diffused system when water quality is the only goal.
Choose a decorative fountain when the pond is also a feature of the community - it aerates while it displays.
Is the equipment certified for municipal projects?
Kasco units are ETL listed to UL and CSA standards, with manufacturer specification documentation available.
We can supply the spec sheets your project file requires.
What size system does a stormwater pond need?
Roughly 1 HP per acre is the standard starting point, adjusted for depth, shape and nutrient load.
Send dimensions and we will provide a written sizing recommendation at no charge.
Who maintains the equipment after commissioning?
Fountain Depot, an authorized Kasco repair shop in Markham, Ontario. GTA sites are serviced directly.
Projects elsewhere in Canada are supported with parts, replacement motors and technical guidance.

I highly recommend the Fountain Depot. Ryan and his team are incredibly knowledgeable and timely. We sought a floating fountain and underwater lights for our client, and Ryan delivered precisely what our client was desiring. The Fountain Place continues to maintain the fountain, and we have had zero issues.
