California Title 22 Compliance

Here is what was submitted to Orange County Health Department to Receive Approval For Title 22 Compliance

California Title 22 Controller Requirements

§ 65523. Operation Records.

(a) Except as provided in Health and Safety Code, section 116048, the pool operator of every public pool open for use at a public pool site shall test the disinfectant residual and pH of the public pool water a minimum of once per day. The pool operator shall also test heated pools’ water temperature a minimum of once per day. The pool operator may perform these daily tests using a properly calibrated automatic chemical monitoring and control system if approved by the enforcing agent and in accordance with the manufacturer’s equipment specifications for calibration and directions for proper use. The pool operator shall maintain a written daily record of all test results, equipment readings, calibrations, and corrective action taken at the public pool site.

(c) The pool operator shall test combined chlorine at a frequency required to maintain maximum combined chlorine concentrations below 0.4 ppm. The pool operator shall maintain a written record of these test results and all corrective action taken at the public pool site.

(e) The pool operator shall maintain a test kit for measuring the disinfectant residual, pH, and, if used, cyanuric acid concentration at the public pool. This test kit shall be available for use by the pool operator and the enforcing agent at all times the public pool is in use. The chlorine or bromine test kit shall be the diethyl-p-phenylenediamine (DPD) type or otherwise be capable of testing free-halogen residual. Chlorine test kits shall be capable of testing for free chlorine and total chlorine, such that combined chlorine concentrations can be determined.

(f) The pool operator shall maintain data and records collected pursuant to subdivisions (a), (b), (c), (d), and (e) for at least two years for inspection by the enforcing agent and shall submit all data and records to the enforcing agent upon the agent’s request.

  1. (a)  PoolWarden controllers are certified by NSF to NSF 50 which is the requirement of LA County and only tests chlorine or bromine residuals and the calibration and control of such sanitizer residuals.
  2. (b)  PoolWarden controllers can be programmed for super chlorination or the addition of a liquid solution of MPS to keep combined chlorine within the required range. NOTE: This will require the weekly testing of combined chlorine to determine if this is needed as the TrueDPD accessory only tests for FAC via diethyl-p-phenylenediamine (DPD)

California Title 22 Controller Requirements

(f) PoolWarden controllers when equipped with internet communication can send and store data on the PoolWarden.com server for the 2 year data requirement and can be downloaded as needed.

§ 65529. Public Pool Disinfection.

(a) Public pools, when open or in use, shall be disinfected continuously by a chemical that imparts a disinfectant at concentrations consistent with subdivision (b) of this section. If halogens other than chlorine are used, residuals of equivalent strength shall be maintained.

(b) The minimum and maximum concentrations of disinfectant residuals in public pool water shall be:

Free Chlorine Residual

Bromine Residual

Min Max

2.0 ppm –

4.0 ppm –

Without CYA

With CYA

Public Pools*

Public Spas, Wading Pools, and Spray Grounds

Min

1.0 ppm

3.0 ppm

Max

10.0 ppm

10.0 ppm

Min

2.0 ppm

Max

10.0 ppm

CYA = cyanuric acid; Min = minimum; Max= maximum; ppm= parts per million. *This includes all public pools except spas, wading pools, and spray grounds.

(e) The pool operator shall maintain a test kit for measuring the disinfectant residual, pH, and, if used, cyanuric acid concentration at the public pool. This test kit shall be available for use by the pool operator and the enforcing agent at all times the public pool is in use. The chlorine or bromine test kit shall be the diethyl-p-phenylenediamine (DPD) type or otherwise be capable of testing free-halogen residual. Chlorine test kits shall be capable of testing for free chlorine and total chlorine, such that combined chlorine concentrations can be determined.

The PoolWarden controller with the TrueDPD accessory can maintain chlorine/ bromine readings to the required ppm levels because it will maintain levels via DPD and not ORP.

California Title 22 Controller Requirements

§ 65530. Public Pool Water Characteristics.
The pool operator shall maintain public pool water characteristics within the following

ranges:

Cyanuric Acid Concentration

Pool Water Temperature

ppm = parts per million.

pH

Minimum

7.2

0.0 ppm

N/A

Maximum

7.8

100.0 ppm

104 F

Combined Chlorine 0.0 ppm 0.4 ppm Concentration

The PoolWarden will maintain pH to required levels and can be set up to manage Total Chlorine residuals via super chlorination or the addition of MPS. This can be controlled by day of week and time. This does require weekly manual testing to ensure the proper management of combined chlorine.
