Water Supply
Garden irrigation and cleaning of outdoor areas – clever, inexpensive and environmentally friendly using rainwater
Rainwater utilisation systems from Wilo pump water directly to the extraction points in the property. Rational use of rainwater is clever, inexpensive and environmentally friendly. With specially designed systems from Wilo, about 50 % of the daily water requirement can be met using rainwater. This way, you can protect the environment and your household budget. Use the valuable liquid that nature provides: With rainwater, you can irrigate your garden and clean your outdoor areas, like patios or garden paths – an inexpensive and environmentally friendly alternative to using drinking water. A rainwater reservoir in combination with a needs-based rainwater utilisation system ensures uniform and low-noise irrigation. Sprinkling, watering, irrigating and cleaning – where drinking water is too expensive, rainwater utilisation is recommended, using a complete system from Wilo.
Continuous power at the highest level
Reliable supply of water in static high-lying taps. Fluctuating water consumption in different types of buildings, such as schools, hospitals or hotels, requires flexible systems which meet individual demands. When gravitational systems such as water towers cannot be used for the water supply due to spatial conditions, a system is required to boost the pressure. These systems provide adequate water pressure in high-rise buildings, in high-altitude inhabited areas and in plant systems, either in supply or circulation systems. Using Wilo pressure-boosting systems, you can ensure that water will be supplied reliably.
Customised Wilo solutions for optimal water pressure
Especially in the case of residential areas that have grown up over time or attic conversions, the pressure cannot be maintained above and immediately below water reservoirs. Therefore, a pressure-boosting system might also be required in residential buildings. Buildings such as apartment blocks, schools, hospitals and hotels place considerable demands on the water supply on all floors. Wilo provides flexible systems for pressure boosting for every installation location to enable a convenient and reliable supply of water. What’s more, a self-priming pump from Wilo is the ideal solution for outdoor cleaning purposes or for plant irrigation. It can be set up next to ponds, lakes, streams or rainwater barrels. This saves on costly precious tap water.
Solution for wells and surface waters
Wherever large quantities of water are needed, the extraction of surface water is also a frequent option. Water is pumped and transferred, for water purification for example, by using shallow wells in lakes or rivers.
The establishment and management of wells are major cost factors in water supply. Of great importance is extensive knowledge in geohydrology, water quality, water resource development options and materials, as well as flow conditions at the well. Having your own well or borehole makes you independent of expensive drinking water and rainwater that is only limitedly available. Wilo submersible pumps will help you pump ground water and irrigate larger areas reliably and easily.
Reliable solutions for all volume flows
Municipal suppliers as well as industry require large quantities of water on a daily basis. Efficient methods and the development of new sources such as desalinated seawater or aquifers (ground water pipes) are possible options for securing future supplies. Ecologically and economically high standards are already being applied to the production of water from lakes, dams, rivers, and seas. A well offers great potential for savings if the pump is operating at its optimum duty point. Wilo submersible pumps can be precisely adjusted to operating conditions. The installation depth and well yield determine which pump to use. The selection criteria are optimal efficiency for minimising energy costs and the use of suitable materials for long-term and maintenance-free pumping operation. In addition, precise trimming of the impeller diameter enables the desired delivery rates to be established precisely. This guarantees you an economical solution. We can handle even fluctuating water levels, for example behind dams, with optimum levels of efficiency and a high degree of operational reliability. For the extraction of water containing corrosive and abrasive elements we use resistant materials such as duplex and coatings like Ceram or Ceram CT. They withstand attacks from aggressive substances and allow long-term pumping operation.
Fire protection and drinking water
Fire-extinguishing and fire protection systems only get used in the event of a fire. They are filled with water and if not flushed, there is the danger that the water could become hygienically unsafe. If such systems are connected to a drinking water installation, they pose a danger to the drinking water. Stagnant water typically forms in fire-extinguishing systems. Stagnant water may lead to pathogenic germs forming. Under DIN 1988 and DIN EN 1717, process water systems such as fire-extinguishing systems are required to be isolated from public drinking water system, e.g. by means of free outflow protection devices (type: AA, AB). The potential hazard of bacteriological re-contamination of domestic and public drinking water systems has to be eliminated by law. In the drinking water separator station from WILO IndustrieSysteme, the certified free outflow type AB is integrated.
Ready for use in every instance
Different building situations, combined with different regional regulations, require specific solutions. Fire-extinguishing systems can be individually assembled with high-quality Wilo components. Profit from our expertise and our highly efficient pump technology. For example, with fully automatic water-supply units in a robust system made up of energy-efficient high-pressure centrifugal pumps and standard motors.
Wilo high-efficiency pumps for firefighting offer solutions specific to the industrial sector and ensure compliance with regional regulations. Our solutions meet the requirements of DIN 14462 for the maximum protection of people, goods and buildings. Just as important is the absolute operational reliability in the event of a fire.
Wilo offers high-quality complete systems for reliable and safe fire water usage. The fire-extinguishing systems from Wilo are particularly suitable
- For wall and exterior hydrants
- For sprinkler systems in addition to wall and exterior hydrants
- For high-rise buildings and properties
Beautiful mountains and long valleys are any walker’s dream. For a water utility company, however, this scenario sets a highly complex set of challenges. Efficient pumps that can constantly provide suitable pressure and good planning are necessary to reliably supply regions that have significant differences in elevation and numerous consumption points that are spread out.
However, even in areas that are less geographically striking, water still has to be transported over long distances and distributed. Especially in large cities with numerous tall and large buildings, distribution at the correct pressure is a challenge that should not be underestimated as it necessitates a huge distribution network of pipes.
Efficient pressure management from the waterworks to the
Reliable and trouble-free supply of water is necessary to guarantee the living standards and health of the population. Old pipework often constitutes a problem as it becomes porous when constantly subjected to water pressure. This, in turn, causes cracks through which water is lost. To prevent this sort of water loss, the water pipe system is constantly inspected by electronic devices. Another means of minimizing the losses due to excessive pressure in the pipes is the selection of the right pump with an efficient pressure management. Reliable, intelligent Wilo pumps ensure that the desired pressure is always provided to the end consumer and any losses and the associated costs are kept to an absolute minimum.
In the agricultural sector, a sustainable approach to the use of water is a basic requirement for the production of natural food under constantly changing climatic conditions. The changing climate noticeably affects production in many regions of the world. Irrigation is necessary under such conditions to secure the crop yields. Other conditions such as too little precipitation or severely fluctuating precipitation also necessitate irrigation to balance out the natural water supply. Irrigation is the key to turning vast areas into usable, fertile land, which would otherwise lie dry and barren. For this reason, artificial irrigation is used worldwide for the husbandry of around 150 million hectares of land.
Modern irrigation systems for agriculture
Modern field irrigation provides differing options for supplying the root systems with ample amounts of water. The water requirement depends significantly on the type of crop sown, the soil conditions and the climate.
Applications in professional irrigation/agriculture
Differing pump systems and irrigation systems are needed to ensure all plants get enough water. Especially in dry regions, it is important to extract and deliver irrigation water as effectively as possible. Wilo has the necessary expertise and the right technologies. Wilo borehole pumps and turbines ensure, for example, that water can be drawn from the ground or from water pipes to safeguard the required supply.
Not all farmers have the same conditions for pumping water. That is why Wilo has developed pumps that can be positioned freely. For example, they can be located quite feasibly on a float to simply pump water from a river or lake. Wilo’s glanded pumps are tried and trusted in practice. They allow you draw off the amount of water you require regardless of the respective water level and transport it precisely to where it is needed.
On large flat surfaces there is often not enough water pressure to secure supply, especially where water levels fluctuate severely. This is where high-efficiency pressure-boosting systems from Wilo come in. They make sure that all of the plants on your fields aresufficiently watered at the right water pressure. That guarantees supply at a constant pressure, even with fluctuating water levels; all done in the most energy-efficient manner possible.
