Quality

How to question and evaluate (new) water technologies

Understanding water technologies is not easy. Water is not easy to understand. Any manufacturere will claim to have the best or the cheapest offer to clean water. Independent professionals in the water industry know that there are no simple answers to “cleanest” or “best” or “most efficient”. It is always a balanced answer and the assumptions are always more interesting than the conclusion.

WaterStillar has developed a small list of 7 areas to question that then gives you a rough profile of any given product

1. How much water

  • Size, energy effectiveness and no of liters per day. Are we in liters per day or M3 per hour?
  • The ratio of reject water.

2. Technical complexity

  • Low tech is always better than high tech – most likely you can fix low tech yourself and it 
  • Can you get spare parts where you live
  • Are you dependent of trained personnel to run the system
  • VLOM score? (Village Level Of Maintenance)

3. Durability and rigidity

  • How sensitive is the technology to – break down and/or quality loss
  • Life time expectancy and ratio of spare parts / consumerables in life time
  • Can the technology break down due to user error?

4. Price

  • Cost of system + shipping + installation + energy consumption + maintenance + spare parts and consumerables + financial cost + downtime cost divided by no of liters in expected lifetime…. is how much is that per liter?
  • When water is compared on price, then remember to compare the quality as well. 

5. Water quality, in and out

  • What are the limitations to feed water (salts, minerals, toxins, temperature etc)
  • Does the quality of the purified water change with time or other parameters
  • What are the long term effects on scaling and biofouling

6. Sustainability

  • Cradle to grave score 
  • How much Co2 (transportation, energy consumption, bottles, visits by technicians etc) is created, using the technology
  • Chemicals used for cleaning
  • Plastic waste
  • Noise

7. Beauty/ design

  • Design matters and should not be ignored. Would you like to show your piece of technology to your neighbor?
  • Is a nice design covering bad quality or does it support good quality

WaterStillar products are all performing with high notes at 2, 3, 5, 6 and 7. But WaterStillar only makes very small amounts of water (1) and compared to filtered water is is quite expensive (4).

Filtered water (RO systems) will perform just opposite of WaterStillar: A lot of water at a relatively low price, but 2,3,5,6 and often 7 will have a lower score. This is to some extent a subjective conclusion and will vary from case to case.

Build quality

AquaDania a/s is a Danish company that today usually uses Scandinavian, German and Italian subsuppliers and manufactorers. Our build quality is state of the art and the quality of steel, glass, enamel etc is the best we can buy for money.

The components are made for AquaDania by subsuppliers and the assembly is done by AquaDania. Each system is pressure tested before leaving the assembly line and a short functionality test is done as well. Therefore there might be a little water left in the tank and the pipes when you install the systems. 

Our subsuppliers are all professionals in their own field. Except from the solar tubes, all material and components are from the EU and made in the EU. All systems are CE approved.
