Compliance Confirmation Needed

Mosquitoes only need a small amount of stagnant water to complete their life cycles. If left unmaintained, a single swimming pool can produce up to 3 million adult mosquitoes in one month. With more than 1660 swimming pools to monitor, this is a huge public health challenge for all residents and the District.

Only two conditions will guarantee that mosquitoes do not grow: "Clean and Functional" or "Empty and Dry." All other conditions will require corrective action by the resident.

There are two types of notices sent to residents with pools: Confirmation Request and Violation Notice. Both require residents to confirm that their pool is "Clean and Functional" or "Empty and Dry."

Acceptable Pool Conditions

Clean and Functional Pool

A Clean and Functional pool has a working pump and filtration system, and a regular chemical treatment schedule. Water must be clear, with little to no algae or debris. Once a clean and functional pool is confirmed, no further action is needed.

Empty and Dry Pool

An Empty and Dry pool is completely dry and free of debris. Mosquitoes will continue to lay eggs and grow throughout mild winters so the pool will need to be emptied between rains. Standing water should not be left for more than four days.

Empty and dry pools need regular maintenance to stay mosquito-free. These pools will require ongoing maintenance by the resident and multiple inspections/confirmations throughout the year. Long-term strategies, such as mosquitofish, may be available for partially filled, non-functional pools.

Note: Swimming pools without water are prone to costly structural damage. The District in no way recommends that anyone empty their pool and encourages residents to research the negative impact of removing the water.
