Eaton Fire / Altadena / Pasadena: The following guidelines are for the maintenance of pools impacted by smoke, ash, or fire damage. Do not use the pool until the steps are completed.
Restoring Water Clarity and Chemistry: Follow the eight steps below to restore water clarity and chemistry in pools with working recirculation systems, electricity, and access to safe water. For pools in the area of the Do Not Drink Order, do not use tap water to refill the pool until the Order is lifted.
1. Skim water surface with a pool net and clean out skimmer baskets to remove all debris. 2. Brush the sides and the bottom of pool to loosen contaminants. Vacuum pool.
3. Backwash and clean the filter(s). Discharge wastewater into a municipal sewer only. Backwashing into the storm drain system (driveways, gutters, streets, storm drains) is prohibited by law. 4. Repeat steps 1-3 if necessary after cleaning the filters. 5. Check the pH value and adjust to between 7.2 and 8.0.
6. Check free chlorine level and adjust to minimum of 2.0 ppm.
7. Check the filter pressure and flow meter to ensure the recirculation system is functioning.
8. Reopen pool to bathers only when the drain cover in the deep end is visible, pH levels are within 7.2 to 8.0, and the free chlorine is at a minimum of 2.0 ppm.
A pool service company may be contracted to clean the pool. Check for their business license and experience. Pool companies are prohibited from discharging backwash to the storm drain system.
Deck Cleaning: Clean the pool deck and dispose of debris into the trash. Do not hose down the deck to storm drains. Minimize dust and ashes from becoming airborne by misting the deck. Then, use a stiff brush or broom to sweep up and discard. A mop and bucket can also be used for cleanup. Draining Pools:
Draining pools is generally not recommended. If you must drain the pool, contact the Department of Public Works’ Street Maintenance and Integrated Waste Management Division for guidance by calling (626) 744-7311.
In general, pool water must be dechlorinated to 0.0 ppm chlorine and have a pH value between 7.2 and 8.0 if it is drained.
Mosquito Breeding: Pools with standing water can breed mosquitoes. During power outages you may need to maintain chlorine manually until the recirculation system is restored. For assistance with a pool that is breeding mosquitoes contact the San Gabriel Valley Mosquito and Vector Control District at (626) 814-9466.
Damaged Pool or Enclosure: Public and multi-unit housing pools that have damage to the recirculation system, the shell, or the enclosure must submit plans or equipment specifications to the Pasadena Environmental Health Division prior to making repairs. Health Department approval is not required for single-family residential pools.
