Storm water treatment

Cleaning of storm sewer pipes up to 1200 mm in diameter

Storm sewers are needed to collect rain runoff. It also serves to drain the water that forms after the snow melts in the spring.

However, the collection of moisture in the system is insufficient. Storm water must be treated before it can be diverted to bodies of water. After all, they are exposed to harmful environments. In particular, wastewater includes:

• residues of fuel and oils of cars;
• chemicals that are applied to roads to prevent icing;
• sand, earth, leaves and branches.

That is why the Chisto Chestno company has been providing services related to washing facades with special means by climbers and from the ground for years.

Cost of work

Special sewage treatment plants are used to treat storm sewage. Thanks to them, water enters the reservoirs already without extraneous pollution and debris.

There are 3 ways to treat wastewater:

1. mechanical. A simple option when a trap for sand and other insoluble waste is installed at the inlet of the cleaning device;
2. physical and mechanical. Retains petrochemical products. For this, the devices are equipped with centrifuges and special adsorption filters;
3. chemical. It is used at enterprises of the chemical and oil refining industries and is designed to neutralize the most toxic substances.

The most effective option is to use a combination of three cleaning methods in one unit. That's why modern stormwater treatment equipment is designed to:

• sand retention and settling;
• extraction of products of the oil refining industry from wastewater using an oil and gas separator;
• filtration of carcinogens and chemicals;
• additional cleaning;
• final check of water for purity level;
• diversion of clean and harmless wastewater to water bodies.

The specialists of the Chisto Honestly company will professionally organize the treatment of storm sewage in your private country house and summer cottage.

Storm sewer maintenance and pipe cleaning

Timely maintenance of storm sewers consists in cleaning and removing debris from pipes and gutters, but the specifics of these procedures differ significantly from work on.

Main stages of work:

• protective grilles are opened and repaired, or replaced with new ones, if necessary;
• cleaning of storm pipes - in long sections they are cleaned through special manholes;
• checking the accuracy of the control sensors.

Timely maintenance of storm sewers will ensure uninterrupted drainage of wastewater and will positively affect the environment. After all, garbage and sludge that settle in gutters and pipes can accumulate harmful substances.

Do not forget that during the period of operation, drainage wells and pipe outlets must be tightly closed with plugs and hatches, this will save them from debris.

It is also worth periodically checking the drainage well for the accumulation of sediment from particles of soil and sand in it, because due to large accumulations, dirt enters the pipes. To prevent this, the drainage must not be forgotten to be cleaned.

This is done independently if you have the necessary equipment, or you can contact the specialists of the Chisto Honestly company for professional help in maintaining storm sewers.

Cleaning storm sewer pipes using the hydrodynamic method

The most effective way to flush pipes is to clean storm sewers using the hydrodynamic method. It is good because with the help of special hydrodynamic machines it is possible to remove complex blockages, while pipes and drains remain intact.

Cleaning storm sewers by the hydrodynamic method includes the use of devices with powerful high-pressure pumping units (HP): 190 - 200 MPa. At the same time, the developers have placed such power in a compact body, which makes the operation of the unit as convenient as possible.

There are 2 options for cleaning storm pipes by the hydrodynamic method:

• strong directed jet breaks and washes blockages;
• cleaning with the use of special nozzles - nozzles that increase the pressure of the main jet and spray thin jets of water around them with great force, which allows you to get rid of the main blockage and clean the inner surface of the pipes from deposits.

As a result, crushed debris under pressure flows out of the pipe and enters the treatment plant.

Cleaning storm sewers by the hydrodynamic method is one of the services provided by the specialists of the Chisto Chestno company in Moscow and the region. We have specialized equipment and extensive experience in such work.
