Is it Okay to Drain a Pool Into the Yard? If you own a pool for long enough, eventually you face the task of draining it. When that happens, you may wonder what to do with the water. After all, that's thousands of gallons of chemically treated pool water; it can't go just anywhere. Are there laws in your area about draining the pool? Is it safe to drain it directly into your yard? Does it matter whether your pool is chlorinated or uses saltwater? Is there anything you should do before draining to make the process safer? Read on for tips on how to safely drain your pool.
Check Before You Drain
Before draining your pool, call or look online for any regulations in your city or town. Not sure where to begin? Start with the environmental, public works, and sewage pages. Another option is simply typing the words "pool drainage regulations YOUR CITY" into Google. Then, just follow the links. If the city has a page devoted to draining your pool, it likely also includes tips on how to do it in a way that follows city guidelines, such as Mesa, Arizona's page on draining and backwashing your pool.
The storm drains in most towns were built to handle standard rainwater, not thousands of gallons of water over a short period, and certainly not water treated with chlorine and other chemicals. Taking on too much water at once may cause flooding and other damage in the sewer system, and pool water may poison local bodies of water. Always check before you drain.
Preparing to Drain: Neutralize pH and Cut the Chlorine
If you know you need to drain your pool, stop adding chemicals to the water for at least a few days. Before you drain, test the water; you're looking for a chlorine level that's either zero or close to it. Chlorine is particularly toxic and could damage your landscaping or infect wildlife should any water enter your local drainage system. You also protect your neighbors' plants from water that enters their yard.
You also want to balance pH levels. Highly acidic water damages landscaping and plants just as chlorine does, both in your yard and beyond it. Again, we're talking about thousands of gallons of water. Unless you empty the pool with a bucket, it's almost guaranteed that some of that water will wind up in a neighbor's yard, surrounding greenbelt, or the local sewer system, so do everything you can to make the water as safe as possible.
Draining a Saltwater Pool
The Dead Sea got its name because its high salt levels inhibit life. Of course, your saltwater pool doesn't have nearly the salinity levels of the Dead Sea, but it's still not a good idea to dump thousands of gallons of saltwater into your yard. For best results, drain your pool in intervals, saturating the ground with fresh water after each draining session.
Avoid Flooding when Draining the Pool
Most yards don't have the ability to absorb all of the water from a pool. One the ground reaches its saturation level, you need to worry about flooding, especially since stagnant water attracts mosquitoes, which begin breeding within two or three days.
Flat, level ground is particularly prone to flooding. Guard against this by moving the hose to different parts of the yard. You may also need to drain the pool in intervals.
