You're responsible for the water people depend on. We make sure it's safe.

The scale of the problem

Contaminated water remains a leading cause of gastrointestinal diseases globally, with outbreaks capable of spreading rapidly through communities that lack reliable purification. For humanitarian organisations, disaster response teams, and underserved communities, the challenge is not just treating water. It's doing so without the chemical supply chains, skilled engineers, or stable power grids conventional systems depend on.

What PaquaVida brings to the field

PaquaVida is designed to work in exactly these conditions. It draws from virtually any freshwater source: lakes, rivers, streams, ponds, boreholes, even heavily contaminated, and produces safe, clean drinking water meeting international standards.

Critically, it does this without any hazardous chemicals. No chlorine dosing systems, no toxic by-products, no complex reagent supply chains. This makes PaquaVida practical in remote or resource-constrained environments where chemical logistics would otherwise make treatment impossible.

Sanitation as a by-product

Beyond drinking water, PaquaVida generates PaquaLyte (an on-site hypochlorous acid disinfectant) as a natural part of its process. This provides a safe, effective solution for sanitation and surface disinfection, further reducing disease risk without additional cost or supply requirements.

Purification and disinfection in one system

Agriculture demands a great deal from its water supply. Irrigation, livestock drinking water, equipment sanitation, and crop storage all require different water quality standards, and all are vulnerable to the contamination risks of borehole and surface water sources.

PaquaVida addresses this with potent bactericidal and extractive properties that remove biological pathogens, heavy metals, and chemical contaminants. The result is clean, wholesome water suitable for the full range of agricultural applications.

HOCl: built-in biosecurity

As part of its purification process, PaquaVida produces PaquaLyte (a hypochlorous acid (HOCl) disinfectant) independently tested against avian influenza, swine flu, and a range of other agricultural pathogens. This gives farming operations a continuous, on-site supply of biosecurity disinfectant with no additional chemical procurement needed.

A more sustainable approach

As water scarcity increases pressure on agricultural regions, PaquaVida also offers a route to responsible water reuse, treating sources that would otherwise be unusable and reducing dependence on mains supply or costly tankered water.

What PaquaVida delivers for crop farmers

Water quality influences every stage of crop production, from germination through to post-harvest storage. Contaminated irrigation water introduces pathogens, heavy metals, and chemical residues that affect plant health, soil biology, and ultimately the safety of the food. PaquaVida removes these risks at source.

The specific benefits for crop farming include:

• Improved soil quality and growing conditions through removal of contaminants that inhibit microbial balance
• Increased crop quality and yield, with healthier plants better able to reach their productive potential
• Safe disinfection of grain in storage, reducing spoilage and waste
• Disease prevention through elimination of waterborne pathogens before they reach soil or plant
• Extended shelf life of vegetables and fruit, particularly where HOCl is used in post-harvest washing
• Purified water for crop spraying, reducing chemical load on produce

Water reuse for irrigation

In water-stressed regions, PaquaVida can also treat greywater or lightly contaminated sources for safe reuse in irrigation, reducing pressure on freshwater reserves and lowering operating costs.

Why water quality matters for livestock

Animals consuming contaminated water are at higher risk of gastrointestinal disease, reduced feed conversion, and impaired immune function. For intensive farming, a single disease outbreak can have significant financial consequences. Yet many farms rely on borehole or surface water vulnerable to bacterial contamination, heavy metals, and seasonal variation.

What clean water delivers

By providing fresh, clean drinking water through PaquaVida, farmers consistently report healthier animals, better growth rates, and reduced reliance on veterinary intervention. Removing pathogens and contaminants at source means livestock aren't exposed to the health risks of untreated borehole or surface water.

A practical, low-maintenance solution

PaquaVida is designed to run continuously with minimal intervention, well suited to working farms where operational demands are high. The system requires only occasional salt replenishment for PaquaLyte production, with no chemical handling or complex maintenance protocols.

A multi-stage process

Most water contamination problems are not caused by a single issue. They typically involve a combination of particulates, heavy metals, biological pathogens, and chemical residues. PaquaVida is designed to address all of these in a single integrated unit, without requiring separate treatment stages or external chemical inputs.

Pre-filtration

The process begins with pre-filtration, which removes suspended solids, sediment, and particulates that would otherwise reduce the effectiveness of downstream treatment stages. This step also reduces turbidity (the cloudiness often associated with contaminated borehole or surface water).

PaquaLyte disinfection

At the core of the treatment process is PaquaLyte, a hypochlorous acid (HOCl) disinfectant produced on-board by the unit itself. PaquaLyte is automatically injected into the water flow at the appropriate stage, killing bacteria, viruses, and other biological pathogens as the water passes through. It also actively minimises biofilm formation within the unit and connected pipework.

Ultrafiltration membrane technology

The final stage uses ultrafiltration membranes to remove any remaining contaminants, including heavy metals, fine particulates, and residual biological material — producing water that consistently meets local and international drinking water standards, including the EU Drinking Water Directive (EU98/83).

Designed for energy efficiency

One of the fundamental design principles behind PaquaVida is that clean water should not depend on reliable grid infrastructure. Many of the communities and sites that need safe water most (remote villages, off-grid farms, island communities, disaster-affected areas) are precisely those where power supply is unreliable or non-existent.

PaquaVida's energy consumption is kept deliberately low, making it practical to power from renewable sources without oversized or expensive installations.

Solar and wind compatibility

The system is fully compatible with solar photovoltaic panels and wind turbines as primary power sources. For installations where power availability may fluctuate, an uninterruptible power supply (UPS) can be integrated to maintain consistent operation, as demonstrated in the Icaros Village deployment on Evia Island, Greece, where PaquaVida operates entirely on solar power with a UPS backup.

Zero-carbon operation

When powered by renewables, PaquaVida delivers genuinely zero-carbon water purification, an increasingly important consideration for organisations with sustainability commitments, municipal operators reducing their environmental footprint, and communities aiming for carbon neutrality.

The problem with ageing water infrastructure

Biofilm (the thin layer of microorganisms that accumulates on the internal surfaces of pipes, tanks, and fittings) is one of the most persistent and damaging issues in water distribution systems. Left unchecked, it harbours bacteria including Legionella, reduces flow efficiency, causes taste and odour problems, and accelerates pipe corrosion. Scale buildup compounds these effects over time.

Conventional approaches to biofilm management typically involve periodic chemical shock dosing, which is disruptive, requires specialist handling, and provides only temporary results.

How PaquaLyte works in the network

PaquaVida generates PaquaLyte as part of its standard water treatment process. A residual concentration of PaquaLyte remains in the treated water as it enters the distribution network. Over time, this residual disinfectant works continuously to break down existing biofilm and prevent new formation throughout the pipework the system serves.

Practical implications

For sites with ageing infrastructure (older hospital buildings, industrial estates, residential developments with long pipe runs) installing PaquaVida does not just treat new water coming in. It actively improves the condition of the network it flows through, reducing long-term maintenance costs and the risk of secondary contamination downstream.

The true cost of bottled and tankered water

The immediate cost of bottled or tankered water is visible and recurring. But the full cost includes procurement management, storage, logistics, plastic waste disposal, and the staff time involved in managing supply. For large sites (hospitals, hotels, factories, residential developments) these costs accumulate quickly and grow with consumption.

What PaquaVida costs to run

Once installed, PaquaVida's running costs are minimal. The system is largely autonomous, requiring only occasional replenishment of the salt used to produce PaquaLyte on-board. There are no chemical purchases, no supply chain to manage, and no tankering costs.

CapEx and OpEx options

Paqua offers both outright purchase (CapEx) and a Water-as-a-Service subscription model (OpEx), allowing organisations to choose the commercial structure that best fits their procurement requirements and cashflow.

An autonomous system

PaquaVida was built with operational simplicity in mind. Once commissioned, the system runs continuously without daily monitoring, chemical dosing management, or specialist intervention. This makes it practical for sites that do not have dedicated water treatment engineers on staff, including remote communities, smaller healthcare facilities, and agricultural operations.

Routine maintenance tasks

The primary routine maintenance task is replenishing the salt reservoir used for on-board PaquaLyte production. This is straightforward, infrequent, and requires no specialist training or equipment. Beyond that, the system's pre-filtration elements require periodic inspection and replacement in line with usage and source water quality.

Remote monitoring and support

Paqua provides remote monitoring of deployed systems, allowing performance to be tracked continuously without requiring on-site presence. This gives both our team and site operators early visibility of any issues, and supports rapid response if maintenance is needed. All installations include on-site training to ensure local staff are equipped to manage the system independently.

No hazardous chemicals

Conventional water treatment relies heavily on chlorine-based chemistry, which produces over 700 known toxic by-products when chlorine reacts with organic matter in water. PaquaVida uses electrolysis and filtration rather than chemical dosing, eliminating this risk entirely. There are no hazardous substances to transport, store, or dispose of.

PaquaLyte: a safe, naturally derived disinfectant

The on-board disinfectant produced by PaquaVida, PaquaLyte, is a hypochlorous acid solution generated from water and salt. It is non-toxic, food-safe, and biodegradable. If spilled, PaquaLyte reverts naturally to water and a small amount of salt, with no environmental residue.

Low energy and renewable-compatible

PaquaVida's energy consumption is kept deliberately low, and the system is fully compatible with solar and wind power. When operated from renewable sources, it delivers genuinely zero-carbon water purification, a strong choice for organisations with sustainability targets, ESG commitments, or carbon neutrality goals.

Reducing plastic waste

For sites currently dependent on bottled water, PaquaVida eliminates the need for single-use plastic entirely. The environmental savings scale quickly: a single mid-sized deployment can remove millions of plastic bottles from the waste stream over its operational life.
