Service water: definition and benefits
Water is the basis of life and the earth. Not only for humans, but also for nature and the environment, water is very precious. It provides essential resources for plants, animals and the habitat. The daily use of water in private households makes it clear how important running water is. The definition of service water is simple. Service water is industrial water and is used in private, technical, commercial and agricultural activities. But beware! Service water is by no means the same as drinking water.
In the industrial and commercial sector, industrial water is strictly separated from drinking water for hygienic reasons. This is because industrial water is often used in conjunction with additives for further processing. With regard to the municipal sector, a separation of service water and drinking water is not intended. From a cost perspective, a separate service water supply makes sense in any case in private households in order to be able to save costs in the long term.
What is service water
Service water, as the word implies, is water that is used in the household or in company buildings as utility water. It is not used as drinking water, but is much more suitable for flushing toilets or watering the garden. Even if the service water is not drinking water, this water must meet certain requirements with regard to hygiene regulations. For example, it should be free of lime and salts.
If industrial water is used for technical processes, it is important that the industrial water is treated appropriately for the machine and the process before each process begins. In agriculture, industrial water is often used to irrigate fields.
Since industrial water cannot compete with the prescribed drinking water qualities, the industrial water is therefore not approved as drinking water. According to the Drinking Water Ordinance(TrinkwV), water is considered to be for human consumption(drinking water) provided it does not pose a risk to the human body.
Extraction in summary
Water for human consumption can be obtained in a variety of ways. In the most common cases, however, it is rainwater or groundwater. Precipitation water or rainwater for private households is collected in a variety of ways. One variant for collecting rainwater is the classic rain barrel. Instead of a rain barrel in the garden, underground cisterns also serve optimally to collect the water fairly. The groundwater can be tapped with pumps. The service water obtained in this way can be used for watering private gardens .
The extraction of service water in the industrial and commercial sector usually comes from waste water that has already been treated. This waste water is also called grey water and is only slightly polluted and free of faeces. The disposal of used industrial water is disposed of through the sewage system, just like any other type of water.
Areas of application for service water
Perhaps you have already read it in the lines between and now already know what the service water can be used for. Here we would like to give you a general overview once again and show you which areas of application may come into question:
Service water in the household
The service water can be optimally used for various areas and can save you money in some household chores. We recommend that you use domestic hot water for the following purposes:
- Toilet flushing: Flushing toilets with domestic water is one way to reduce water consumption, as this accounts for a large proportion of household water use.
- Washing machine: for the use of clean laundry.
- Cleaning: Domestic water can be used for cleaning the house, windows and floors.
Service water for the garden
Service water is a precious resource not only in the household, but also in outdoor areas such as the garden. Use your collected rainwater as service water and water your green areas and plants easily and cost-effectively. By the way, service water on reserve turns out to be worth its weight in gold, especially on hot summer days.
- Watering plants: Industrial water can be used to water plants, as it is often rich in nutrients and no drinking water is wasted.
- Property cleaning: Industrial water can be used for cleaning pavements, cars and other items.
In general, industrial water should not be used as drinking water unless it has first undergone appropriate treatment and purification to ensure its quality and safety.
The water we refer to as domestic water can be of varying quality, depending on its source and use. Rainwater or the water from a shower or washing machine, for example, may contain impurities or pollutants that make it unsuitable for human consumption.
It is important that domestic water is used only for appropriate purposes. Make sure it is suitable and safe for each specific purpose. If you are not sure whether the domestic water is suitable for a particular purpose, it is better to use drinking water.
Yes, it is possible to treat industrial water and bring it to drinking water quality. There are various technologies and processes that can be used to treat industrial water, such as membrane filtration, reverse osmosis, ozone treatment, UV irradiation and chemical treatments.
The exact type and extent of treatment depends on the quality of the source water and the requirements of the end user. However, treating industrial water to drinking water quality is usually more complex and expensive than treating surface water or groundwater because the source water often contains higher concentrations of contaminants.
The cost of domestic water can vary widely by region and provider and depends on a number of factors, including the type of domestic water, the amount of water needed, infrastructure, and operating costs for water treatment.
When it comes to using rainwater or treated wastewater for watering plants or flushing toilets, the cost is often lower than for drinking water because no extensive treatment is required. In some cases, these alternatives can even be free if the rainwater is collected on one's own property or if there are local initiatives that promote the use of domestic water.
There is often an additional cost for using treated wastewater as domestic water, as it is usually more expensive to treat and distribute than rainwater. These costs can vary by region and provider and should be checked with local water utilities if needed.
Industrial water and drinking water are both types of water, but they differ in composition, quality and use.
Drinking water is suitable for human consumption and must therefore meet certain requirements set by the Drinking Water Ordinance. For example, drinking water must be free of pathogens, chemical contaminants and other potentially harmful substances. It is provided by local water utilities, which ensure that it meets the required quality standards.
Industrial water, on the other hand, refers to water that is not intended for human consumption and can be used for various purposes, such as watering plants or flushing toilets. Industrial water can come from a variety of sources, such as rainwater, graywater, or treated wastewater.
