bogwarrior 0 #1 March 1, 2004 Hello. My name is David Cowman . I work on growing dropzone in central spain called Skydive Lillo. We are affilliated to the United States Parachute Association. Recently we have dug the pit for a swoop pond that is 100m in lenght. We are however unsure how to proceed on a number of fronts. Principally we are concerned with the following two issues: 1. Water retention in the pond. We have to pay water rates. What are the different methods that DZ owners may have used to stop ground water leekage ? Is it as simple as plastic and silicon , or have you found a better more efficent method ? What are your experiences? 2. Water stagnation is a concern as the drop zone is warm for 11 of 12 months of the year ,with temperatures ranging from 11 degrees in the Winter to 30 - 35 degrees in the summer. What type of water filtration or circulation devices do you use to avoid smells. Some poeple have suggest small amounts of chlorine in the water ? Is this not bad for gear ? Any advice that you or somebody on your DZ would have to share with us in Skydive Lillo would be appreciated very much. Quote Share this post Link to post Share on other sites
AggieDave 6 #2 March 1, 2004 I've seen folks use the same kind of plastic used for backyard ponds in swoop ponds before, that may be an option for you. Also, you could always use an agitator fountain (whats found in some stock ponds for cattle) to keep the water moving. Then remove it for swoop comps, etc. Those are just my thoughts, though.--"When I die, may I be surrounded by scattered chrome and burning gasoline."
