Innovative Smart Greywater Recycling Solutions for Residential and Commercial Use.

Grey-water is lightly contaminated wastewater from bath and shower, shower, and optionally from washing machines, hand basins, air conditioning units and heat pumps. It doesn’t include wastewater from the kitchen or toilets, and it doesn’t contain sewage (black water).

NOTE: handbasin water can only be used in H600 and Cascade set ups and cannot be water from the kitchen.

Hydraloop® water is treated reusable water. It is clean, clear, safe, and disinfected, ready for re-use.

Yes. Hydraloop® water is clean, clear and disinfected. The treatment technology is NSF-350 certified and meets the most stringent international standards. Hydraloop® water should not be used for drinking, cooking or personal hygiene.

The Hydraloop® system is not meant for producing drinking water. 

Hydraloop® water is suitable for toilet flushing, washing machines, garden irrigation and topping up swimming pools.

You can not use Hydraloop® water in your shower, bath, or bidet. There are standards in place that decide what one can use the recycled water for. These differ per country. Generally, you are not allowed to shower/bath with recycled water (although it would be safe).

When you install a Hydraloop®, you could set up your rainwater tank solely for irrigation and use recycled Hydraloop® water for toilet flushing and the washing machine. You can recycle, for example, 75,000 liters / 21,000 gallons with H300 and 150,000 / 40,000 gallons for H600 a per year.

If you recycle more water than you use inside the building, Hydraloop® can pump the surplus to a rainwater tank. This way, you can use Hydraloop® water to irrigate the garden and optimise your usage of recycled water. You can also keep collecting rainwater in a tank for garden irrigation.

We believe that rainwater should contribute to the hydrologic cycle and not flow into the sewer. Using Hydraloop® water inside and outside, and using rainwater only outside is the most sustainable way to reuse water.

Hydraloop® uses a unique combination of sustainable water treatment technologies to ensures the highest water quality, without requiring regular maintenance or causing harm to the environment.

Hydraloop® patented technology is consumer friendly, carefree and sustainable. The treatment process removes hair, dirt, soap and other pollution from grey-water without the use of filters, membranes, or chemicals, so there is no need to clean and exchange filters. This reduces operational costs substantial.

Hydraloop® water treatment combines six technologies: sedimentation, floatation, dissolved air floatation, foam fractionation, an aerobic bioreactor, and disinfection of the treated water with powerful UV light. 

In standby mode and during water treatment, the Hydraloop® units make a sound of approximately 44 db. You can compare it with the sound of a silent dishwasher. The sound comes from the dissolved air floatation (bubbles) within the system. Another sound that is noticeable is when the water pump is pumping, although this is only a brief moment and the pump is a silent pump.

When you have used all of the Hydraloop® treated water, the system automatically switches to regular tap water. As soon as new Hydraloop® water is available, the system automatically starts to supply this recycled water again.

A single Hydraloop® H300 or H600 system can feed up to four (4) toilets at a maximum distance of 20 meters wide and 12 meters high. Cascade systems can be equipped with an external booster pump to extend the range and number of toilets. 

The warranty period for your Hydraloop® unit is specified set in your Warranty Certificate. This certificate may vary according to national law.

We offer the Hydraloop® Care option to extend the warranty on all component for 5 years or longer. Hydraloop® Care be extended for up to 20 years. Details are available up on request.

The lifespan of a Hydraloop® unit is at least 20 years

Yes. The wall power outlet must have earth safety protection and should preferably be positioned above or next to the system.

The Hydraloop® H300 system has a weight of 82.5 kg. When it is filled with water, it has a maximum weight of 383 kg.

The Hydraloop® H600 system has a dry weight of 128 kg. When it is filled with water, it has a maximum weight of 739.5kg.

Before you install the system, make sure the floor can carry a minimum of 800 kilograms per m2 (for the H300 system) or 1,000 kilograms (for the H600 system).

Yes. Hydraloop® can be retrofitted to existing homes and apartments. However, you have to make sure the building is Recycle Ready. 

If you need to break walls to install a Hydraloop® system, getting your building Recycle Ready might become costly. The most economical way is to combine the installation of a Hydraloop® system with a home or bathroom renovation.

Yes. Hydraloop® can be installed in any new building if the plumbing is installed correctly. But you have to make sure the building is Recycle Ready. 

One of Hydraloop®’s benefits is that our systems don’t use filters or membranes, so they can’t clog, and you never have to clean or replace a filter. This reduces costs too. All Hydraloop® units work fully automatic and have a regular self-cleaning mode.

We recommend a preventive maintenance check by your Hydraloop® installer once every two years.

No, you don’t need to use special cleaning products or laundry detergents. The only requirement is that you use products without bleach in your bathroom cleaning products (for all showers and baths that are connected to the Hydraloop®).

If you clean your shower or bath with a product that contains bleach, you need to restart the bioreactor with your smartphone app. The ‘start-up procedure’ currently takes 21 days. Hydraloop® will soon offer a bioreactor vitalizer (in the form of a (re)starter kit) which will shorten the start-up period to 7 days. 

In short: the H300 has the ideal treatment capacity for a household of up to four to five people (in Europe, where people on average use 45 liters | 12 gallons of water per person for showering).

The H600 has the ideal treatment capacity for small businesses and larger households (and for households in countries where people on average use 90 liters | 24 gallons of water per person for showering).

The Hydraloop® Cascade is scalable and made-to-measure, so it can handle projects of any size.

Size H300: W:34 cm (13.4 inch) x D: 80 cm (31.5inch) x H:185 cm (74 inch) / 6.1 foot)

Size H600: W:68 cm (26.8 inch) x D 80 cm (31.5 inch) x D: 185 cm (74 inch) / 6.1 foot)

Electricity: + 175 KWh/year (H300), + 350 KWh/year (H600)

Hydraloop® Cascade is a multiple of the number of Hydraloop® units.
