For smaller rinks, we sometimes fill up with well water, and as long as you have a good aquifer it can be fine. However, for a larger rink, we utilized the potential of roof run-off to fill the rink for free instead of using well water, or worse yet, buying water! We had a rink that was 50' x 65' (3,250 ft2) and an average of 6" deep (approximate volume of 12,155 gallons), and we filled it quickly for free by simply using our roof run-off.
We did this by connecting some of our roof's downspouts to pvc pipes (using elbows at the bottom to connect to horizontal pvc pipes lying on or partly buried in the ground) which connect into each other at the corner of the house. We then built what we called the "Alaskan pipeline" of several pvcs pipes (using bricks and scrap wood to support them) across the yard to the closest edge of the ice rink. We used a level to make it to slope just slightly downhill across the entire length (to prevent freezing blocakges) because the level of the lowest downspout and the level of the rink were about a 1 inch difference.
Our house is a modestly sized rancher, and when we did the math, we realized that we could get thousands of gallons off the roof in a very short amount of time. With just one day of steady, moderate rain, the rink was completely filled and ready for freezing. We disconnected and reconnected the last section of pipe on the pipeline to control topping up or resurfacing if we needed to adjust things.
We used old pvc pipes that we had lying around (many were cracked or had holes, so we put the cracks and holes to the top so that the bottom few inches were solid to allow water to flow without leaking). If one doesn't have pvc pices, it's a good investment to buy them and avoid paying a few hundred dollars each year to fill up an ice rink. They quickly pay for themselves.
In the summer, we use the downspouts to collect and store roof run-off in large barrels to water the garden.
