Drain your pool wisely
Chlorinated swimming pool water may also not be discharged into the municipal separate storm sewer system (MS4) or storm drain. The MS4 conveys water directly to rivers and streams, and chlorinated water can kill aquatic life.
In-ground pools typically have a sanitary sewer drainage inlet near the pool equipment. Pools and spas not plumbed with a sanitary sewer drainage inlet can be drained to a sanitary sewer line plumbed to the home. Consult a licensed plumber or pool professional if you are unsure how to go about draining your pool.
Pool water should never be drained to the street or the storm drain. Storm drains in the Bay Area typically run into local creeks, rivers and the bays. In most places, it's against the law to drain pools and spas this way because pool water contains chemicals that can endanger or kill wildlife.
A freshly chlorinated pool should not be discharged into the yard; the chlorine is harmful to yard plants and the environment as a whole. Using a test kit, your pool water needs to reflect a certain concentration of chlorine, such as 0.1 ppm (parts per million), before it is safe to drain into your yard.
All you need is a medium-size water or vacuum pump. Unroll the pump's intake hose so that it reaches the center of the pool (or as close to it as possible), and submerge it in the pool. Place the outlet hose so the exiting water doesn't flood the area, but drains off away from the pool.
Though it's illegal to discharge swimming pool/spa backwash and drainage water off your property, in general you can dump this water into the public sewers. You can also reuse this water to help your thirsty plants! Emptying a Pool/Spa the Plant-Friendly Way: Draining an Aboveground Pool/Spa 1.
Put one end of your garden hose inside the port. Thread the hose to the back of your house. Attach the other end of the garden hose to a submersion pump and place the hose and pump in the deepest area of your pool, near the drain. The pool will begin to drain.
Even with proper and regular pool maintenance, it's often necessary to drain your pool — completely or partially — every 3-5 years. Draining your pool often isn't necessary, especially if you're following a proper and regular maintenance program.
Swimming pool builders often install overflow drains near the rim of the pool that prevent flooding most of the time. If you don't have an overflow drain, or if it is clogged, it is possible for periods of unusually heavy rain to overflow your pool.
If you only need to dechlorinate a bit of pool water to irrigate a tree or a shrub, you can use a bucket. Scoop out a bucket of water and place it in a sunny spot. Leave it in the sun for a week, and the chlorine should be evaporated.
Shut off the pump. Go to the back of the filter and unscrew the drain plug. Turn the pump back on and let the water run until it reaches the point where you want to drain the water out. Turn the pump back off and put the plug back into the drain plug.
If you can pump around 30 GPM (gallons per minute), which is also equivalent to 1800 GPH (gallons per hour), it should take you 2.78 hours or 2 hours and 46 minutes to drain your pool using a hose.
This siphoning process is simple enough. Immerse the entire hose in some water, then cover one end of the hose with your hand and quickly pull it out of the pool, pointing down below the water level. If you don't cut the hose, you may need to attach the hose to your spigot and fill it with water.
Locate the Drain Valve
The drain valve is located on the outside of the pool. Run a garden hose out, with the female end near the drain valve. Connect the other end to a sprinkler, and water your lawn or garden (if pH is good and chlorine low). Remove the cap.
A: It's a waste, but fresh pool water is not safe for irrigating plants. It's because the chlorine in pool water is very toxic to plants. If the chlorine level is low enough, it's possible to use it. Chlorine is a great disinfectant and used for killing human pathogens associated with food crops such as E.
Chlorinated water, such as that from a pool is not suitable for watering plants. High levels of chlorine are toxic to plants. However, water compositions with low chlorine contents may be used, and even prove helpful for the plants.
Swimming Pool Water Harms Plants
Swimming pool water contains chemicals, especially chlorine, that can harm your trees and landscape plants when water drains and floods the area. Too much chlorine can damage tree leaves and other delicate tissues. Too much chlorinated water all at once can even kill trees.
A 10,000 gallon pool will take about 14 hours to drain, the maximum rate recommended by the City of Phoenix. It will take twice as long to drain if the pool size is doubled or cut in half.
If you decide to drain this pool yourself, you will first need to rent a sump pump that can be submerged under water. After renting the proper sump pump, connect it to the sewer access point and submerge the other end in the pool. Plug the pump into an outlet and let it go to work.
Main Drain: The main drain is typically located at the deepest point of the pool and is used to lower the water level, however its primary purpose is to circulate water from the bottom of the pool. It is recommended that about 1/3rd of the circulated water come from the main drain.
Use Hydrogen Peroxide
Hydrogen peroxide is a powerful oxidizer and reacts with chlorine to produce water and oxygen. It is working if you notice small, effervescent bubbles in the pool. For the best results, use hydrogen peroxide that is formulated for pools.
2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, water circulation, and aeration will speed up the evaporation process dramatically. Chlorine will last between 6 and 8 minutes in 10 gallons of boiling tap water.
Chlorine naturally dissipates into the air and out of your pool water when exposed to sunlight. The process usually takes less than a week. If you plan on using pool water to irrigate your trees, don't add any more chlorine to your pool. After four or five days, test the water.
