How does a rainwater system work?

Can we have a look at an exsisting project?2022-09-06T13:47:53+00:00

We strongly recommend that. Send us a message and we will find the closest project so you can get the feel.

How do I find resellers in my country or region?2022-09-06T13:45:06+00:00

If you are looking for a resseler of our systems you can sent us a message via the contact form.  Our sales team is happy to support or answer questions you might have.

Can I buy the parts and install it myself?2022-09-06T13:22:33+00:00

As we are working with installation, service & maintenance (ISM)  proffesionals and qualified resellers you are enabled to purchase your systems via them. Parts are provided with warranties and dislaimer. Read installation manuals carefully.

We have a luxery resort and ambition to become energy neutral. Can you support us?2022-09-06T13:14:38+00:00

Our systems are scalable and when our local reseller is performing the preperation and installation activities the rainwater to drinking water is certified to be 99.99% bateria free and certified to your local standards at minimum. This applies to our PV panels and batteries and our natuaral fecal systems.

What do I need to purchase?2022-04-17T16:02:22+00:00

To install the Agua del cielo SafeWater system you require either the ADC 10, 20 or 30 litre filter system. The components to complete your system could vary. What you normally require;

From our factory:
The ADC SafeWater system, Number 1 in the picture.

From our local Reseller / ISM provider:
Rainwater storage tank, Number 4 in the picture.
Rainwater filter, Number 5 in the picture.
Pressure hose, Number 6 in the picture.
Submersible pump, Number 7 in the picture
Expansion vessel, Number 9 in the picture
Level measurement with replenishment unit, Number 10 in the picture.
Replenishment line to the tank, Number 11 in the picture.
Expansion tank for pressure stroke pump, Number 12 in the picture.

You can also request an proposal. Provide us with some basic information on the roof surface, gutters, nearby surfaces. If you have a drawing of your development or excisting house, resort or hotel, please send that to us.

Our Resellers & ISM providers have gutters, dust and debries filters for sale and are able to construct the Rainwater storage tank according to our specifications. Shipping a collection tank and those gutters, dust and debries filters components are not included as you can imagine that purchasing that localy is much more economic. Of course our sales teams will support you.

Can I shower with rainwater?2021-12-24T08:11:57+00:00

With rainwater you can shower and wash yourself perfectly. Rainwater is soft and therefore wonderful for your skin, much nicer than the hard drinking water. Moreover, you will never again have lime deposits in your bathroom.

To make the rainwater suitable, it is purified by a membrane and a UVC unit. After collection in the tank, the rainwater is transported inside with a submersible pump. There are two or three tanks in your house. In the first one, a membrane station is installed. There the rainwater is purified. The second (and third) tank contains the clean rainwater. The rainwater station uses this water to transport it to all consumer appliances, such as the shower, taps, washing machine and toilets. An UVC unit has been placed next to the rainwater station. This provides a double purification of the rainwater.

How does a rainwater system work?2021-12-24T08:19:47+00:00

The composition of a rainwater system is actually quite simple. The rainwater flows down from the roof via a rainwater pipe and is led to the rainwater tank via an underground pipe. This tank can be made of concrete or plastic, usually has a capacity of approximately 5,000 litres and is preferably placed underground. A filter with a non-return valve is installed in the tank. It removes the impurities that flow along. The excess rainwater is led outside of the tank via a siphon. This overflow can be connected to the sewer, to surface water or to an infiltration facility.

The filtered water flows into the tank via a gentle inlet. It is then transported indoors by a suction system. Inside your home or business there is a rainwater station that transports the rainwater to the consuming appliances. This rainwater station is equipped with a pump, control unit and drinking water replenishment. If the level in the tank is too low, the rainwater station automatically switches to drinking water. A float in the tank ensures the signalling.

Rainwater system for commercial and non-residential buildings
The system works basically the same for companies and commercial buildings. The system is only larger in terms of storage, filtering and pumping capacity.

Is rainwater the same as greywater?2021-12-24T08:23:19+00:00

Many people speak of grey water when they mean rainwater, but it is not the same thing. Rainwater is simply the water that falls from the sky, but greywater is the wastewater from the bathroom.

How much rainwater can I collect?2021-12-24T08:25:51+00:00

There is a simple rule of thumb for calculating the amount of rainwater you can collect annually with your rainwater tank or cistern. Per m2 this is approximately 650 litres. So if you have a roof of 100m2, you can collect approximately 65.000 litres or 65 m3 of rainwater for use.

Then you can calculate how big your rainwater tank should be. Often, 5% of the annual volume is used, which would result in a tank of 0.05 x 65 = 3.25 m3. However, due to the changing climate and longer drought periods, we feel this is too little and therefore calculate a minimum of 8% (or a month’s supply). In the example, this means that you need a rainwater tank or cistern of 0.08 x 65 = 5.2 m3.

Can rainwater from a green roof be reused?2021-12-24T08:29:31+00:00

Green roofs are becoming increasingly popular because of the many advantages they have in terms of energy, cooling, clean air and rainwater. Green roofs retain a lot of rainwater and evaporate it through the plants. The surplus rainwater can also be perfectly reused for flushing the toilets, for cleaning and for the garden.

When reusing the rainwater, it is decoloured by an active carbon filter and, if necessary, micro-organism-free with membrane filtration. In case of heavy rain showers, the excess rainwater can be infiltrated into the soil.

What happens when my rainwater tank is empty?2021-12-24T08:32:41+00:00

What happens when my rainwater tank is empty? This is a frequently asked question, but the answer is simple. Every rainwater system always has a mains water backup. Depending on the type of rainwater system, either the tank is 10% filled with mains water or the pump system automatically switches to mains water. This happens automatically and you don’t have to do anything.

When choosing a rainwater tank it is, of course, important to take the changing climate into account. Our advice is to choose a large tank which will provide you with at least one month’s supply. If it is very dry for four weeks, you can continue to use rainwater from your own tank.
