  • When designing and installing domestic wastewater treatment plants in commercial buildings, the same basic principles apply as in private homes. Depending on the specifics of the site, the planned wastewater volumes change and solutions are selected accordingly to ensure that the treatment plant has the time and quality to treat the water.
    The designers determine the volumes of future wastewater. It is estimated that 90 litres of used water per employee per day will be discharged into the sewage system in office buildings. In commercial buildings, where water consumption is unevenly distributed, it is necessary to construct storage tanks, in other words, equalization tanks. The water is then discharged piecemeal to a treatment plant and treated. This is usually the case for agritourism farms, where water use is particularly high at weekends. If the plant has an equalization tank, it can be balanced to treat smaller volumes, according to standards designed for fewer users than will actually be present.
    Not all manufacturers have equalization tanks. We can help you find the right option, advise you on the best solution for your specific situation, and ensure that the water is treated to a high standard, the plant is easy to use and the money spent on wastewater management is used wisely.

  • Rain falls equally on private and commercial buildings and their yards. Commercial buildings and their yards tend to have more hard surfaces, such as asphalted driveways, paved walkways and rest areas. As a result, more water, which has nowhere to be absorbed naturally, accumulates, so the installation of rainwater harvesting systems in commercial buildings requires the construction of more manholes and the laying of more pipes underground to carry the water to ready-made containers.
    Puddles in the yard don’t just get the feet of employees, guests and customers wet. Water is a powerful force that slowly destroys buildings and property.

  • Collection of petroleum waste is needed in areas where cars leak any kind of liquid, including water after washing. These include car parks, garages, car washes, etc.
    Every drop of petroleum products harms the environment and damages nature. The biggest danger is that these products easily leak into nearby drinking water sources, wells or boreholes. The ground is the best filter for oil pollutants, but this requires a depth of up to 40 metres. Wells are usually less deep. Irresponsible handling of oil waste not only leads to living in a polluted environment, but also to hefty fines.
    The efficiency of oil-contaminated water treatment plants is calculated in terms of how many litres of water pass through them per second. The filtered petroleum products remain in the trap. The asenizers collect them and take them to designated sites for disposal.
    Unfortunately, many small garages and garages next to houses do not have such treatment facilities. The grease, mixed with water, flows freely through the yard, slowly soaking into the ground. Householders who do not install an oil waste collector are happy to save money, but do not consider that they are poisoning themselves and their families through the well or borehole water.
    Buildings with oil waste must have their yards paved with concrete. Gutters are formed to channel contaminated water through oil traps into storm water runoff.

  • Why do you need to collect grease from wastewater? The reason is simple. Grease is not food for the bacteria in water treatment plants, so it builds up and deteriorates if untreated. And when it burns, it smells bad – much worse than other wastewater, believe us! One can only ask rhetorically: does anyone like living in a smelly environment?
    Capturing waste grease from water is based on the same principle as petroleum products. Its efficiency is also determined by how many litres of water it filters per second. Usually, designers calculate the size of grease trap needed in each specific case.
    Water with grease from dishwashers, kitchen sinks is directed through a pipe from the building to a grease trap. Neither rain nor sewage water shall enter it. After passing through the grease trap, the water shall be diverted to the general effluent.
    Grease traps are necessary in commercial buildings, cafes, restaurants, hotels. We have seen landlords installing wastewater treatment plants but not installing a grease trap to save money. The stench that soon follows is reminiscent of the old folk proverb – “A cheapskate pays twice”. Installing a grease trap when the entire wastewater collection system is already in place costs extra time and money.
    Odour is not the only problem. Hot water with grease cools down about 30 metres of pipe. If coffee grounds or other food waste has been poured in, it and the grease stick to the pipe walls and form a perfect clog!
    Coffee grounds are not evil in themselves, running off like sand, but when mixed with grease they become a strong building material that clogs up the sewage pipe.
    Grease traps are not usually installed in individual houses because there is less waste. However, even small accumulations of grease can cause problems, so it is advisable not to pour much of it down the drain. And absolutely no used oils should be poured down the drain! There are companies that buy them and then use them to produce biofuels.
