A new bathing water regulation in the Netherlands – fit for the future!

Wilfred Reinhold 6th International Conference

n Swimming Pool and Spa

19 March 2015

SLIDE 2

Current regulation

Dates from 1969
Old standards for chemical, physical and

microbiological water quality

Requirements for pool operation such as

– capacity of the pumps – filter backwash procedure and frequency – volume of supplement/dilution water (30 liters of drinking water / bather / day)

Aim of regulation: achievement of a safe

and healthy swimming pool environment through strict requirements

±1500 public and semi-public swimming

pools in the Netherlands

2 Ministry of Infrastructure and the Environment

SLIDE 3

Towards a new regulation

From strict requirements  towards regulation that specifies that the swimming pool environment should be safe and healthy for its users,  regardless of the way pool operators achieve this goal

3 Ministry of Infrastructure and the Environment

Pool managers and operators get opportunity and responsibility  to make their own choices in how to achieve this goal accommodates innovation & application of novel technologies.

SLIDE 4

Consultation of local & provincial authorities and the public

Draft texts and reports published on www.internetconsulatie.nl
Period: September - November 2014
>20 persons/organisations submitted comments
From short to quite long comments (dozens of pages)
In total: comments on nearly 300 aspects of the regulation
At this moment: finishing the processing of the commentary
Comments lead to changes in details, not in the structure of the

proposed regulation –

Duty of care

Section 3

Operator shall ensure that hygiene and safety in the swimming pool

environment is sufficiently ensured

If operator knows / should suspect the bathing complex can cause

adverse effects on hygiene / safety of visitors , he must take measures to prevent / limit those effects

New parametric values for water and air

Section 4 to 6 + Annex I

Class I Class II Class III Free Available Chlorine: 1.0±0.5 Bromate: ≤50 µg/l Available bound chlorine: ≤0.6 mg/l Acidity (pH):7.30±0.30 Sum Trihalomethanes (as CHCl3): ≤50 µg/l Chlorate : ≤30 mg/l Transparency: floor of pool Pseudomonas aeruginosa ≤0/100 Urea: ≤2.0 mg/l Legionella: <100 cfu/l Intestinal enterococci: ≤0/100 Nitrate: ≤50 mg/l Spores of sulfitereducing Clostridia (SSRC): ≤0/100 Hydrogen carbonate: ≥40 mg/l Staphylococcus aureus: ≤0/100 Chloride: ≤800 mg/l KMnO4–consumption: ≤3.0 mg/l O2 Turbidity: ≤0.50 FTE Trichloramines: ≤0.50 mg/m3 air Ozone: ≤120 ug/m3 1-hour air

Risk analysis: Not entirely new

Operators already have experience in Risk analysis and management
f legionella + Risk assessment and evaluation based on Health

and Safety legislation + HACCP based on Consumer Legislation

Some operators have already decided for such an approach

(responsibility , corporate culture, savings )

7 Ministry of Infrastructure and the Environment

SLIDE 8

Risk analysis + management plan + measures

Section 7 + Annex II

Pool managers analyses the apparent/

expected risks for health/safety of the users

f the pool environment
Document the used method and results
Description of the measures to be taken
Attention for risk of Legionella
Carry out the management plan
Keep risk analysis+management plan up to

date!

Save documents and results for inspection
Law enforcer must be able to inspect them

8 Ministry of Infrastructure and the Environment

SLIDE 9

Risk analysis Risk model = guideline

Operator should take into account aspects such as:

design, operation and maintenance of technical

installations

risk of drowning or suction trapment
risk of microbiological contamination of the water
prevention of overdose of chemicals
risk of malfunctioning of (parts of) the technical

installation

health and safety aspects (such as slippery floors)
number and type of visitors (age, swimming skills,

vulnerable groups)

Special basins

Section 8 to 13 (+ Annex III Swimming Ponds)

Shallow basins (≤ 50 cm)
Swimming Ponds (biological cleaning method)
Floating tanks (addition of magnesium sulphate
r other salts in water)
Basins for single use by one person
Fish spas
Flowed through basins (water is constantly

discharged; discharged water does not return)

Special parametric values/monitoring requirements
Special aspects for risk analysis and management
