7–4. The difference between a decorative and interactive fountain program
For decorative fountains, CDC emphasizes sediment and biofilm management, temperature, water retention, and residual disinfection. Monitoring of important parameters is recommended at least weekly, and the condition of the environment or design may require more frequency. Observation of apparent contamination should enable corrective action. CDC Guidelines for Decorative Fountains [446]
For water playgrounds, CDC operational guidelines state the following:
subject | The amount or frequency listed in the guide |
|---|---|
pH | 7.0 to 7.8 |
Free chlorine without using cyanuric acid | At least 1 mg/L |
Free chlorine if cyanuric acid is used | At least 2 mg/L |
Go to the whole system | At least 3 mg/L |
Disinfectant and pH control | Before reopening and every 2 to 4 hours during operation |
circulation time | 30 minutes or less |
Equipment performance inspection | Daily before reopening |
These values are not the upper limit of the material or the license to use the stabilizer; The approved plan, material limit, manufacturer's order and local authority regulations must be followed simultaneously. Guidelines for the operation of CDC water playgrounds [447]
7–5. Registration of non-compliance
Time to discover | problem | Restriction or suspension imposed | corrective action | Retest result | Permission to reopen |
|---|---|---|---|---|---|
…… | …… | …… | …… | …… | …… |
In the event of pollution, the amount and method of correction should be extracted from the approved instructions of the same system. Experimental addition of chemical without measuring and recording is not a water quality control method.
