Best: reusables guests already carry
Refillable bottles and mugs are everywhere now. High-flow cold taps make them the easiest choice on a hot Alberta day.
Rivers & responsibility
Alberta’s rivers run huge. Single-use bottles do not have to. We bring cold filtered refill so events skip the flats, the haul, and the maybe-landfill “recycling.”

Refill over plastic
Environment and economics
Hauling recyclable PET off a field still costs crews, trucks, and sorting — and plenty of that plastic never becomes a new bottle. A refill station is the cleaner, cheaper habit: pour on site, leave the park without a mountain of empties.

02
When reusables are not enough for the crowd, compostable or sponsor-branded cups beat shrink-wrapped flats of PET that may still end in landfill.
03
Buying, chilling, handing out, and hauling single-use bottles burns budget and leaves a trash problem. Refill shrinks that pile before it starts.
Named for Alberta rivers
Hay and Beaver are not decoration. We ranked Alberta rivers by volume and named the lineup so the bigger station carries the bigger name. See the water stations — and the arithmetic that ties a wagon to a watershed.
River vs wagon
Nerdy scale
River figures are approximate mean annual discharge. Wagon pour rates use an illustrative ~2 L/min per tap. This is arithmetic for perspective — not a hydrology study or a measured station certificate.
One second of river
At about 783 m³/s mean discharge, one second of the Athabasca moves roughly 783,000 litres. The Hay Wagon at an illustrative 2 L/min per tap peaks near 0.3 L/s — so the river outruns the wagon by about 2,349,000 times in that same second.
Five seconds of Athabasca
Five seconds of mean Athabasca flow is about 3,915,000 litres. Five seconds of the Hay Wagon at peak illustrative rate is only about 2 litres. Rivers remind us how small a station is — and how large the plastic pile gets when we bottle every sip.
A festival day of guest water
If 6,250 guests each drank half a litre from the Hay Wagon, that day of water is about 3,125 litres — roughly 0.00 seconds of the Athabasca at mean discharge. Cold refill on site; no flats of PET to buy, chill, and haul away.
