Rainwater Harvesting Systems

Rainwater Harvesting Systems are a proven and environmentally friendly technology.
The Bio Pure Tech  Rainwater Harvesting System has the following benefits:
Box_TickProvides soft, non-chlorinated water ideal for home use in washing machines, dishwashers, flush toilets, power-hoses, showers, watering garden plants and also for commercial use in cooling systems, power washers etc.
Box_TickHelps prolong the life of washing machines and other appliances as the water is soft. (Most normal water is ‘hard water’ which can cause lime-scale).
Box_TickDecreases burden on existing waste-water and sewage systems.
Box_TickCuts down on mains water treatment costs, including the use of various chemicals, fluorides and electricity consumption.
Box_TickHelps alleviate areas prone to flooding.
Box_TickIdeally suited for industrial usage where high volumes of water is needed.
Box_TickSaves money on water charges which are now in operation in Ireland.

How much water do we use? Can we really save money?

With water rates now an unfortunate reality, a household can still save 50% of water consumption using a rainwater harvesting tank, reducing your water bills.

A family of 4 consumes on average more than 150,000 litres of water per year, the majority of which is for non-drinking purposes (see chart opposite). Studies show that 55 per cent of domestic treated water could be substituted for rainwater while a staggering 85 per cent of water used for commerce and industry does not need to be of drinking standard.

Check out some of these facts on Money Guide Ireland.

While there is an initial cost of installing a rainwater harvesting system, this will easily be recouped and quickly begin to save money over its lifetime. Rainwater can be safely used for a variety of non-potable purposes including flushing toilets, running washing machines, cleaning cars and watering the garden. It is also invaluable for agriculture and industry - two of the largest water consumers - where it can be used for factory cooling systems, cleaning vehicles and equipment, and for irrigation.

If you are looking for a long-term solution to reducing your water consumption and saving money, the Rain Water Harvesting system offers the best possible solution available today. We can install this system on new builds, or retrofit to work with existing water systems. For a competitive quote, call us now on 086 1520035 or use our Enquiry Form.

Why Rainwater Harvesting Makes Sense

If there’s one thing which Ireland has in abundance, it’s rain, and lots of it. Ireland has on average about 150 to 200 days wet days (1mm rain or more) per year. Take a look at the diagram on the right. Here's a link to more info on the Met Eireann website. With the highly contraversial domestic water charges now in-place, it makes sense to find ways of cutting down on the use of water to save money.
While there are plenty of ideas for reducing usage such as putting both kids in the bath at the same time, putting rocks in your toilet cistern to reduce the amount of water flushing, and cutting down on those long showers, these aren’t exactly practical for most people.
We still take water for granted and usually don’t think about where it comes from, how much we actually use and where it goes when we’ve used it. We don’t really care. After all, as tax payers we have paid for the infrastructre to be put in place to ensure that we have an endless supply of clean water. Unfortunately, it’s not as simple as that, and the sad fact is that our water is less than perfect, there is a huge amount of wastage and leakages, not all of it is of usable quality, and the infrastructure is in poor shape.

Bio Pure Tech’s Rainwater Harvesting Solution. How does it work?

The Rainwater harvester is an environmentally friendly system that collects, siphons and pumps rain-water, allowing the clean water to be used domestically in your toilets, showers, baths, washing machines, car washing and irrigation systems, which represents the majority of our water usage.

The system can also provide huge cost savings in the provision of water for agricultural or commercial usage in factories, for example for cleaning equipment or vehicles, cooling systems and irrigation. Take a look at the 6 steps of rain water harvesting below.

STEP 1: FILTERING
The first cleaning step in the rainwater system is the filter. The rainwater flows from the roof to the filter. Here dirt particles and debris are separated from the water. The cleaned water flows to the tank. The dirt is washed to the sewer or soakaway with a small amount of rainwater. All new Intus rainwater filters have stainless steel inserts, which are easy to remove and to clean. Their many different working principles and connection possibilities afford their use in many different installation situations.
STEP 2: CALMED INLET
By using an underground tank, the water is stored in dark and cool conditions. Here the second cleaning step takes place. In the water column, any residual dirt particles sink to the base of the tank. The rainwater Calmed Inlet prevents any disturbance of the sedimentation layer. At the same time the lower layers of the stored water are supplied with oxygenated water. This oxygen rich water prevents anaerobic reducing conditions forming in the storage tank and the water stays fresh.
STEP 3: OVERFLOW SIPHON
Any particles that are lighter than water (e.g. flower pollen) float slowly to the water surface. The expertly designed new Intus overflow siphon, with a skimmer effect, removes this floating layer. The regular overflow from the storage tank is important to get the best water quality. It prevents souring of the water. The floating layer could otherwise prevent oxygen diffusion at the water surface, which could lead to anaerobic reducing conditions in the tank., and the onset of odour problems.
STEP 4: FLOATING PUMP INTAKE
The pump intake floats suspended just below the water surface where the cleanest water lies. From this position the water is abstracted by the pump. A ball float, filled with air, suspends the intake valve, which has a further filter. Usually the Floating Pump Intake has a check valve.
STEP 5: SUBMERSIBLE PUMP
The Submersible pump can pump the water directly to the point of use, or pump up to a header tank in the attic. The pump will keep the pressure at 1 BAR and up to a maximum of 4 BAR. The pump will start operating automatically as the pressure in the line drops ie. when a tap is turned on, then the pump will restore the pressure in the pipe. The pump will pump 20-80 litres/min up to a maximum head of 30m.
STEP 6: MAINS TOP UP
The function of the mains top up is to allow mains water, where available, to top up the tank when the water level drops to a minimum level. The system will allow approximately 200 litres at a time into the tank until rainwater enters the tank again. The mains top up system also prevents any water being syphoned out of the tank which can happen in other rainwater systems.
