Installing a water recycling solution in your commercial real estate is a profitable investment. Sustainability requirements for buildings are becoming more demanding and real estate investors require sustainability certifications for their property, such as LEED and BREEAM.

Hydraloop® contributes to future-proofing the building, contributes to its sustainability certification, and contributes to the United Nations Global Goals. Hydraloop® increases the value of any building and lowers the running expenses for water and energy.

Hydraloop® collects and treats the water from showers, hand basins, and air-conditioning units in commercial buildings of any size. The treated and disinfected water is suitable for toilet flushing, washing machines, garden irrigation and topping up swimming pools.



Ideal for use in small businesses and more

For smaller commercial real estate, like office buildings, bed and breakfasts, or gyms, we recommend the Hydraloop® H600 unit, with an average cleaning capacity of 1000 litres per day. 



A smart solution for larger water consumption.

For larger commercial real estate, like hotels, sports clubs, and student housing, the required water treatment capacity can easily be configured by the amount of Hydraloop® units that are interconnected into one Hydraloop® Cascade recycling plant. We offer made-to-measure solutions for your project.

With the scalable and made to measure Hydraloop® Cascade system, you can recycle up to 95% of shower, bath and/or handbasin water + the cooling water from air-conditioning units. Due to its innovative and breakthrough technology the maintenance requirements and corresponding costs are very low.

The Hydraloop® Cascade can be assembled by configuring two or more Hydraloop® units in cascade arrangement. Depending on the building and the application, one central location can be chosen in the building for one cascade configuration. Or several locations with two or more compact cascade configurations.

Each Hydraloop® unit in the cascade set up works independently in the cleaning process. The treated and disinfected recycled water is stored in one volume which is formed by the interconnected individual water storage tanks of the Hydraloop® units. Treatment and storage tanks form one integral cluster. A powerful booster pump distributes the recycled water in the building to be used for toilet flushing and garden irrigation. In case of a temporary shortage of recycled water, the system automatically switches to its back-up water source like tap water or rainwater.


Hotels & Lodges

Hydraloop® lowers water and energy bills, makes your business more sustainable and less dependent on the grid, and contributes to eco-conscious travel.

Delivering high-end service requires hotels to offer their guests the best experience. Unfortunately, this involves using lots of water and energy. By installing a Hydraloop® water recycling solution in your business, you can start saving on water and energy, and bills from day one.

Making sure there is enough water to run your business is the highest priority, especially in dry regions and in areas where water supply isn’t always reliable. With Hydraloop®, your hotel will not just become more sustainable, but by treating and recycling water on site, your business will become more resilient and less dependent on the grid.

Today’s consumers are more aware of their impact on the environment than ever before. Consciousness and sustainability are becoming important factors in the way people plan and book their travels. Studies find that travellers who book sustainable accommodations, on average stay three days longer than other guests*. Climate-conscious travellers – people who want to reduce their carbon footprint – are a fast-growing group with a large influence on their peers and the leisure industry as a whole.

Hydraloop® FAQ's

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 80 kg. When it is filled with water, it has a maximum weight of 360 kg.

The Hydraloop® H600 system has a weight of 160 kg. When it is filled with water, it has a maximum weight of 

Before you install the system, make sure the floor can carry a minimum of 1000 kilograms per m2 (for the H300 system) or 800 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 4 – 5 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)
