SUMMER IS HERE! β˜€οΈ πŸ–οΈ We all enjoy spending summer by the pool πŸ’§, but if you need to drain your pool, spa or fountain, these requirements must be followed: βœ” Reach a PH level of 7-8. βœ” Must be dechlorinated, have no other chemicals. βœ” Pathway to the storm drain inlet must be cleared of all sediment and debris. βœ” Water must be at ambient temperature. βœ” Use water to irrigate lawns. πŸ€” Why? It is illegal to drain pools without using the best management practices listed above. That’s because we must keep pollutants like algae, chlorine, salt and other hazardous chemicals out of storm drains, which flow to local waterways and the ocean. ⚠️ πŸ‘‰ Learn more at bit.ly/ThinkBlue-Pools-Spas . . . #ThinkBlueSanDiego #SanDiego #Summer2023 #SanDiegoSummer #StormwaterRegulations #Compliance #Pool

Happy International Surfing Day πŸ„β€β™€οΈ πŸ€™ Polluted beaches harm our wildlife AND humans. #DidYouKnow Surfers and swimmers are generally advised to avoid the ocean for 48 hours following significant storm events? Why? Because anything that enters our storm drains goes UNTREATED into our rivers, creeks, bays, and the ocean. 🌊 We strongly believe that everyone should have access to clean water. So, let’s do our part to protect our waters and beaches so we can continue to surf, swim and play in the ocean. THINK BLUE SAN DIEGO πŸŒŠπŸ’™πŸŒŠ Tag your favorite surfer to spread the word! . . . #ThinkBlueSanDiego #SanDiego #InternationalSurfingDay #SanDiegoSurf
