District of Columbia law prohibits the release of swimming pool water to public space. Your discharge choice will depend on where the swimming pool is situated within the District. Seek the help of a licensed plumber about the suitable method to connect the pool drainage system prior to discharging the water. Pool water may be discharged Directly to the sanitary sewer or the combined sewer system in a way that satisfies the criteria of the District of Columbia plumbing codes and DC Water pre-treatment program. Contrary to the MS4, the sanitary sewer and combined sewer systems carry wastewater to the Blue Plains Wastewater Treatment Plant for elimination of harmful pollutants before it is discharged into the Potomac River. To determine if you are in a combined sewer area, please see Find Your Watershed or telephone -LRB-202-RRB- 535-2600.
If your pool isn’t directly connected to the sanitary sewer, then consider using other sanitary sewer connections in or around your dwelling. Use a hose and pump to drain pool water to plumbing fixtures connected to the District’s sanitary or combined sewer. Seek the help of a licensed plumber about the right connections and flow rate for pumping and discharging water. When washing pool filters, then discharge the wash water into the sanitary sewer system. Based on the type of filter, it may be as suitable to throw the used filter from the garbage for solid waste disposal. Chemically dechlorinate the pool water. Chemicals which will quickly eliminate chlorine are accessible through pool and spa maintenance providers. Follow the directions on the product label.
Chlorine is among the most common Chemical additives used to control bacterial growth in swimming pools and find more information on https://gharpedia.com/blog/draining-swimming-pool/. With appropriate chlorination, swimmers can allow pool water to get hold of the skin and incidentally swallow a pool water with very little fear of infection. However, as valuable as chlorine can be in controlled circumstances, its release to the environment is prohibited and punishable by law. The federal Clean Water Act and the DC Water Pollution Control Act prohibit the discharge of pollutants into the waters of the District of Columbia. Even seemingly tiny concentrations of chlorine can damage or kill aquatic life. The U.S. Environmental Protection Agency admits that in 1mg/L or less chlorine has a high acute toxicity to aquatic organisms. It is against District and national laws to release chlorinated water without reducing chlorine to acceptable levels < 0.1 mg/L. Follow the chemical use, handling, and storage directions carefully, as some dichlorination products can become dangerous when brought into contact with other pool maintenance chemicals.
