jacissel.com is where I purchase the aquanet from. I dont recall the price, but it was a great deal!
The waterslide plastic is 80" wide by 100' long. It was leftover from a local trucking company. They use it to line semi's.

We have about 25' of fall for the 85' slide and we use a 2" trash pump to pump water.
10' would be fine if you could get a running start to gain momentum.
