6 Simple Steps to Collect Sample at Home
There is a lot that goes into actually ensuring the water we drink is safe and clean, including testing.
Select your service package and complete the online order
Prepare a distilled water bottle for sampling. It is not recommended to use bottles of mineral water because the residuals will affect the test results. Fully rinsed before use.
Take the first use 800ml water sample of the day.
Put a label with application number on the bottle (the application number will be mentioned in confirmation email of your order)
Promet arranges courier to collect sample(s) from you.
You will receive the test results within 7 working days by email.
Sampling Protocol for Premises
Promet carries out sampling according to the “Sampling Protocol for Commissioning Test of Fresh Water Plumbing System”, which can be applied to the water supply guideline “New Commissioning Requirements for New Plumbing Works”, “New Commissioning Requirements for Plumbing Works in Occupied Buildings/Village Houses” and “Water Sampling and Solder Joint Sampling and Testing for Newly Installed Fresh Water Inside Service” issued by Water Supplies Department.
Our sampling specialists went through relevant and proper training and are familiar with the sampling procedures and handling of water samples, will ensure that the samples are representatives of water quality of the premises and free from contamination during the course of sampling, sample storage and transportation.
Our sample bottles are made of qualified plastic material with a capacity of 1-litre for metal tests, 500ml for chemical and physical tests and 250ml for bacteriological test. All sample bottles are prepared in accordance with the ISO standards.
Our specialist will collect water samples at the locations selected by WSD according to the steps outlined in the WSD Sampling Protocol, and record all information and observation.
All sample bottles will be labelled immediately, stored properly and delivered to the laboratory for testing as soon as possible.
For the Drinking Water Safety Test for Premises, Promet will send the test results by email as soon as they are ready, a printed report and certificate of compliance will be issued within a week after the completion of test.
As for Commissioning Test of Fresh Water Plumbing System and New Commissioning Test for Plumbing Works in Occupied Buildings/Village Houses, Promet will submit a complete report to the WSD within 5 days after collecting the samples for the later water meter application.
What is the best time of the day shall I collect the water sample(s)?
We would recommend you collect the water sample(s) before the first use of water in the early morning. After a night of stagnation, if the water sample(s) collected at that time pass the requirements, the results are more accurate.
How often do I need to test water quality?
We would recommend to conduct a water quality test if you have never done that before. Afterwards, we would suggest a regular check every year. On the other hand, we would recommend to conduct a test in the following circumstances:
- If you install a new pipe or faucet at home
- If you install a new water filtering system
- If your building installs new piping
- If you find any abnormality in your water colour, odour, taste or any presence of residuals

Health Risks of Heavy Metals
(Video available in Traditional Chinese version only)
View Video
Excessive exposure
Excessive exposure of heavy metals in drinking water can cause development delays, high blood pressure, organ damage, cancer, and other severe health effects.
Young exposure
The young are more prone to the toxic effects of heavy metals, as the rapidly developing body systems in the fetus, infants and young children are far more sensitive.
Childhood exposure
Childhood exposure to some metals can result in learning difficulties, memory impairment, damage to the nervous system, and behavioral problems such as aggressiveness and hyperactivity.
WHO Guidelines for
Drinking Water Quality
The Guidelines cover a broad range of chemicals that can affect drinking water quality but not all chemicals will be relevant within a country. To learn more about the list of chemicals, their guideline values and its hazards in drinking water, please click here.
Hong Kong Drinking Water
Standards (HKDWS)
The Government currently adopts the corresponding guideline values / provisional guidline values in the 4th edition of the WHO's Guidelines published in 2011 as the Hong Kong Drinking Water Standards. Details can be found here. Promet’s report is based on HKDWS criteria, compare if the Hong Kong households water meet the specifications.

Potential Health Hazards
Antimony trioxide is possibly carcinogenic to humans.
Acceptance Criteria (in μg/L)
≤ 20
Potential Health Hazards
Long-term exposure to arsenic in drinking-water is causally related to increased risks of cancer in the skin, lungs, bladder and kidney, as well as other skin changes, such as hyperkeratosis and pigmentation changes.
Acceptance Criteria (in μg/L)
≤ 10
Potential Health Hazards
Barium has been shown to cause nephropathy in laboratory animals.
Acceptance Criteria (in μg/L)
≤ 700
Potential Health Hazards
Short- and long-term oral exposures to boric acid or borax in laboratory animals have demonstrated that the male reproductive tract is a consistent target of toxicity.
Acceptance Criteria (in μg/L)
≤ 2400
Potential Health Hazards
Classified as probably carcinogenic to humans, cadmium accumulates primarily in the kidneys and has a long biological half-life in humans of 10 to 35 years.
Acceptance Criteria (in μg/L)
≤ 3
Potential Health Hazards
It is classified as human carcinogen.
Acceptance Criteria (in μg/L)

Potential Health Hazards
At high concentration level, copper imparts an undesirable bitter taste to water and may impact the colour of water. Copper contaminated drinking water brings gastrointestinal effects.
Acceptance Criteria (in μg/L)
≤ 2000
Potential Health Hazards
Exposure to lead is associated with a wide range of effects, including various neurodevelopmental effects, mortality (mainly due to cardiovascular diseases), impaired renal function, hypertension, impaired fertility and adverse pregnancy outcomes.
Acceptance Criteria (in μg/L)
≤ 10
Potential Health Hazards
The toxic effects are seen primarily in haemorrhagic gastritis and colitis; the ultimate damage is to the kidney.
Acceptance Criteria (in μg/L)
≤ 6
Potential Health Hazards

pH is a measure of how acidic/basic water. pH ranges from 0 to 14, with 7 being neural. pH of less than 7 indicates acidity, whereas a pH greater than 7 indicates a base solution. Pure water is neutral, with a pH close to 7.0 at 25°C. Normal rainfall has a pH of approximately 5.6 (slightly acidic) owing to atmospheric carbon dioxide gas. Safe ranges of pH for drinking water are from 6.5 to 9.5 for domestic use.
A high pH makes the taste bitter and decreases the effectiveness of the chlorine disinfection. Low-pH water will corrode or dissolve metals and other substances.
Acceptance Criteria (in μg/L)
≥ 6.5 and ≤ 9.5 (at 25°C)
EC is a measure of the ability of a solution to carry or conduct an electrical current. Conductivity in water is affected by the presence of inorganic dissolved solids such as chloride, nitrate, sulfate, and phosphate anions (ions that carry a negative charge) or sodium, magnesium, calcium, iron, and aluminum cations (ions that carry a positive charge).
Acceptance Criteria (in μg/L)
≤ 500 μS/cm (at 25°C)
Colour is graded on scale of 0 (clear) to 70 Hazen unit (HU). Pure water is colourless, which is equivalent to 0 Hazen unit.
Acceptance Criteria (in μg/L)
≤ 5 HU
Turbidity is a measure of the ability of light to pass through water. The particulates can provide hiding places for harmful microorganisms and thereby shield them from the disinfection process. Suspended particles provide adsorption media for heavy metals such as mercury, chromium, lead, cadmium, and many hazardous organic pollutants.
Turbidity more than 5 NTU can be visible to the average person while turbidity in muddy water, it exceeds 100 NTU.
Acceptance Criteria (in μg/L)
≤ 3.0 NTU
Chlorine (Cl₂) does not occur naturally in water but is added to water and wastewater for disinfection. While chlorine itself is a toxic gas, in dilute aqueous solution, it is not harmful to human health. In drinking water, a residual of about 0.2 mg/L is optimal. The residual concentration which is maintained in the water distribution system ensures good sanitary quality of water.
Acceptance Criteria (in μg/L)
≤ 1.5 mg/L
