Swiss Laboratory for Drinking Water Analysis – We Test the Quality of Your Drinking and Tap Water
Biolytix AG is your Swiss service laboratory with more than 25 years of experience in water analysis and EN/ISO 17025 accreditation for all legally relevant microbiological hygiene parameters.
A microbiological drinking water analysis lets you check the hygienic quality of your drinking water and detect possible contamination by microorganisms. This can be useful, for example, if you want to check the quality of your tap water or if you have concerns about water hygiene.
For private households, we offer a simple way to have your drinking and tap water professionally tested in our laboratory: choose the right analysis kit and send your water sample to our laboratory for testing. Once the analysis is complete, you will conveniently receive the results by email.
Our customers include water suppliers, general contractors or building technicians, installation or plumbing companies, facility management, building and property management or caretakers, public institutions, hospitals, nursing or residential homes, schools, sports and fitness facilities, hotels or community facilities, baths or wellness facilities, plant operators or product manufacturers from industry and pharmaceuticals.

Microbiological analysis for Drinking Water

Drinking Water Testing from the Household Installation: Mikrobiology
100.00 CHFTotal microbial count (Aerobic, mesophilic germs), Enterococci, Escherichia coli.Microbiological testing of drinking water hygiene in domestic installations (tap, shower etc)This analysis package provides you with a comprehensive overview of the microbiological information required for drinking water hygiene in accordance with the Swiss Drinking Water Ordinance (TBDV), as well as the total microbial load:
The total microbial count (also known as aerobic, mesophilic microorganisms) gives insight into the general bacterial load of the water. According to the TBDV, this parameter is examined within the distribution system up to the building inlet but is also a relevant indicator for evaluating water quality within domestic installations up to the tap.
Enterococci and Escherichia coli are indicator organisms that signal microbial contamination and must not be present in drinking water in accordance with the TBDV.
Note: Additional chemical and physical parameters for assessing drinking water quality—such as sensory inspection for turbidity, color, and odor, as well as testing for pH, water hardness, nitrate, heavy metals like lead, or metals like copper and iron (indicative of corrosion), pesticide residues, or PFAS—can be found under “Chemical and Physical Water Quality Analysis”.100.00 CHF -
Drinking Water Testing from the Household Installation: Extensive Testing
355.00 CHFTotal microbial count (Aerobic, mesophilic germs), Enterococci, Escherichia coli., Conductivity, pH value, Total hardness, Carbonate hardness, Nitrate, Pb: Lead, Cd: Cadmium, Cr: Chromium, Cu: Copper, Ni: Nickel, Fe: Iron, Mn: Manganese, Color, odor, turbidity (sensorial)Microbiological, chemical and physical testing of drinking water in domestic installations (tap, shower etc)This analysis package combines microbiological testing of drinking water with selected chemical-physical parameters: In addition to microbial drinking water hygiene according to the Swiss Drinking Water Ordinance (TBDV), water hardness, sensory properties (color, odor, taste), pH, Conductivity, nitrate content, and some metals and heavy metals (lead, cadmium, copper, nickel, iron, manganese) are determined. This package provides information on the quality of the water, the pipes, and potential risks to your health and household appliances.355.00 CHF -
Drinking Water Testing for Water Dispensers
130.00 CHFEnterococci, Escherichia coli., Pseudomonas aeruginosaMicrobiological analysis of drinking water bottled for distribution as foodstuff or dispensed via water dispensers (in gallon containers or from domestic installations)This analysis package provides all necessary information for the microbiological assessment of drinking water quality from water dispensers in accordance with the Swiss Drinking Water Ordinance (TBDV): Enterococci and Escherichia coli serve as indicator organisms for microbial contamination that must be excluded. Pseudomonas aeruginosa, a waterborne microorganism with potential health risks, must also be absent from drinking water from dispensers, as required by the TBDV.130.00 CHF -
Drinking water testing of the water supply to the building
100.00 CHFTotal microbial count (Aerobic, mesophilic germs), Enterococci, Escherichia coli.Microbiological testing of drinking water hygiene in the distribution network according to TBDVThis analysis package provides an overview of the microbiological hygiene of your drinking water provided by the water supplier within the distribution network, based on the requirements of the Swiss Drinking Water Ordinance (TBDV): The total microbial count (also known as aerobic, mesophilic microorganisms) gives insight into the general bacterial load of the water. According to the TBDV, this parameter is examined within the distribution system up to the building inlet but is also a relevant indicator for evaluating water quality within domestic installations up to the tap.
