Pool Prep
Pools and spas are a great addition to anyone’s home, but when they are drained and cleaned improperly they can pollute lakes, creeks and bays. Copper is a pollutant that affects aquatic life and is used as an algaecide (a chemical treatment that kills algae) in pools and spas. Draining pool water into storm drains can pollute water with copper, chlorine and other contaminants.
Viewer Tip: A properly maintained pool will reduce the need for drainage. Manage the pH to minimize copper pipe corrosion and clean regularly to maintain proper chlorine levels. Here are tips on cleaning and draining:
Cleaning
- Never clean a filter in the street or gutter.
- Rinse cartridge filters onto a dirt area. Collect materials on a filter cloth and throw it away. If you do not have a suitable dirt area, call your city’s Environmental Services for guidance.
Draining
- Don’t drain your pool or spa into the street or gutter.
- Before draining, make sure all the chlorine in the pool is gone. Chlorine dissipates over time. Monitor for three to five days, testing the chlorine levels. Gradually drain the pool water onto a landscaped area to prevent erosion.
