INVESTING IN FREEDOM AND SAFETY - why invest in Carawater systems?

Besides the additional advantages of Carawater systems the answer lies within two critical questions.

1. Water Quality – How Safe Is Your Water?

Whether from the tap or a natural source, the water you rely on may contain invisible threats. Below is a list of common contaminants, how they affect your health, how to remove them (Filter micron Rating must be an absolute rating not nominal to be effective), and what happens when they’re stored in a water tank.

Note: Protozoan parasites (cyst) like Giardia for example can survive for weeks within a tank environment in cyst form and multiplication only occurs once ingested inside a host body.

Biological Contaminants (Pathogens)

Contaminant	Type	Effects on Humans	Filtration or Treatment	Behaviour When Stored Tanks
E. coli	Bacteria	Severe diarrhea, vomiting, kidney damage (in some strains)	0.2-micron to 0.5-micron filter UV-C disinfection Chlorination	Can survive and multiply if biofilm forms
Salmonella	Bacteria	Typhoid fever, food poisoning, gastroenteritis	0.2-micron to 0.5-micron filter UV-C disinfection Chlorination	Can survive in stagnant or warm tanks
Campylobacter	Bacteria	Diarrhea, cramps, fever, nausea	0.2-micron to 0.5-micron filter UV-C Chlorination	Survives days to weeks in water
Legionella	Bacteria	Legionnaires’ disease (severe pneumonia)	0.2-micron filter Heat disinfection chlorination	Multiplies in warm, stagnant tanks and plumbing
Giardia	Protozoan parasite (cyst)	Diarrhea, cramping, dehydration	1-micron filter UV-C disinfection	Does not multiply, survives in cyst form for weeks
Cryptosporidium	Protozoan parasite (cyst)	Watery diarrhea, dehydration, especially dangerous for immunocompromised	1-micron filter UV-C (high dose) disinfection	Very resistant; survives chlorine, persists in tanks
Norovirus	Virus	Vomiting, diarrhea, fever	UV-C (adequate dose) 0.001-micron Nanofiltration Chlorination	Does not multiply but remains infectious in tanks
Rotavirus	Virus	Severe diarrhea in children	UV-C (adequate dose) 0.001-micron Nanofiltration Chlorination	Remains viable in water for weeks
Hepatitis A	Virus	Liver inflammation, nausea, fatigue	UV-C Chlorination 0.02-micron ultrafiltration	Can remain active in stored water

Chemical & Dissolved Contaminants

Contaminant	Type	Effects on Humans	Filtration or Treatment	Behaviour in Stored Tanks
Lead	Heavy metal	Brain damage, developmental delays in children	Activated carbon + Reverse Osmosis	Does not degrade; accumulates if present
Arsenic	Metalloid	Cancer, skin lesions, circulatory issues	Reverse Osmosis, activated alumina	Remains stable; does not decay in tanks
Nitrates/Nitrites	Fertilizer runoff	Blue baby syndrome, oxygen deprivation	Ion exchange, Reverse Osmosis	Stable; accumulates in tanks
Chlorine	Disinfectant	Taste/odour, eye and skin irritation	Activated carbon	May dissipate over time
Chloramine	Disinfectant	Long-term exposure risks; kidney stress	Catalytic carbon	More stable than chlorine; remains in tanks
Fluoride	Additive	Dental/musculoskeletal issues in excess	Activated alumina, Reverse Osmosis	Stable in storage
Pesticides/Herbicides	Agricultural runoff	Hormone disruption, cancer risk	Activated carbon, Reverse Osmosis	Can persist for weeks in tanks
PFAS (Forever Chemicals)	Industrial chemicals	Hormone disruption, immune suppression, cancer	Activated carbon (specialized), Reverse Osmosis	Do not degrade, remain indefinitely

Other Contaminants

Contaminant	Type	Effects on Humans	Filtration or Treatment	Behaviour in Stored Tanks
Sediment & Rust (Iron)	Physical particles	Low levels – generally not harmful. High concentrations – stomach discomfort, nausea, vomiting	1-micron to 20-micron sediment filters	Settles to bottom if undisturbed
Algae	Microorganism	Taste/odour issues, potential toxins	UV-C, activated carbon	Can bloom in light-exposed tanks
Nano & Micro Plastics	Synthetic particles	Unknown long-term effects; potential toxin carriers	0.02-micron filters, Reverse Osmosis	Remain suspended or settle slowly
Organic Matter (Tannins)	Natural compounds	Discoloration, musty taste	Activated carbon	Stable in tanks; can support bacterial growth
Iron & Manganese	Metals	Metallic taste, stains, pipe scaling	Sediment + oxidation + carbon or Reverse Osmosis	Can precipitate and form sludge

The contaminants listed above represent a broad sample of the biological, chemical, and physical threats that can be present in both city water and natural source water. While not exhaustive, this list highlights the diverse range of potential health risks, from bacteria and viruses to heavy metals, pesticides, forever chemicals and plastics.

Critically, once water enters a storage tank whether on a caravan, boat, or off-grid system it is subject to changes that can affect its safety including:

Stagnation, heat, and light exposure may allow microbial regrowth.
Biofilm and sediment buildup can shield pathogens from disinfection.
Chemical contaminants do not degrade and may accumulate over time.

This underscores the importance of a two-stage filtration approach within tank preservation an additional safety measure:

Pre-filtration before water enters the tank to block or neutralise harmful contaminants from city or natural sources.
Post-tank (point-of-use) filtration to ensure safe, clean drinking water at the tap by removing or disabling any contaminants that may have persisted or formed in storage.

Only by filtering both before and after the tank can you confidently protect yourself from the full range of waterborne risks whist maintaining tank health.

2. Investment – The Value of Quality?

When comparing Carawater water filtration systems against alternatives, please consider the following to ensure you have the most important information to hand.

Filter Ratings: Absolute Ratings means the filter is designed to remove ≥99.9% of all particles at the rated micron size or larger. Nominal Rated Filters will remove approximately a certain percentage (typically 60% to 95%) of particles at or above the stated micron size.

Filter Cost: While the initial cost might appear higher, the extended life (capacity) of Carawater systems and their advanced features ensure long-term value. We suggest basing comparisons on 100 litres of processed water per replacement filter, we suggest using the replacement filter costs as this represents the long-term ongoing cost.

Product Names: Be aware of products using levels of filtration in their names, check the filter micron rating and whether it is an Absolute or Nominal rating to be sure of what the actual efficiency.

UV-C performance: 99.999% effectiveness is based on three main criteria.
- First the clarity of incoming water, every impurity creates a shadow of untreated water. Without turbulence inside the reactor as is created inside the Carawater reactors with a patented process these blind spots allow for sections of water to remain untreated.
- Second is the UV-C wave length 265nm is the wavelength at which 99.999% is achieved as in the Carawater LED UV-C reactors. Anything other is an immediate reduction in effectiveness.
- Third is the UV-C Dose, this is shown in unit of measurement (mJ/cm²). Drinking water systems typically aim for a minimum UV dose of 40 mJ/cm² to ensure a high level of disinfection of 99.999% including virus level inactivation.

Certification & Standards Compliance: Carawater components are manufactured to stringent engineering standards and are independently third party tested for compliance and performance versus in-house or generic standards that usually claim to be “Tested to” a specific standard.
