Called Sani-dumps over there, this one in Mount Kidd RV Park in the Peter Lougheed Provincial Park on the Kananaskis Highway in Alberta had 8 individual dump points complete with rinsing water hoses and a separate potable water tap a few meters along from each dump point. The park has hundreds of sites. Most of which were occupied.
That's Erich doing the deed in our rented Motorhome. We avoided rush hour by leaving around 9am.
This highway closes during winter and only opened the week before we arrived.
