Various types of wells
Service well
The UKOS-DV-KT technical wells provide for servicing underground tanks. The depth of the technical well depends on the depth of the inlet pipe tray leading to the treatment plant.
| KT type | 1 | 2 | 3 | 4 | |
| h | Distance from inlet pipe to ground level | 900 - 1 300 | 1 300 - 1 700 | 1 700 - 2 100 | 2 100 - 2 500 |
| Stairs | - | available | available | available | |
Equipment dimensions are adjustable.
Equipment may be manufactured after customer drawings.
Distribution well
SNiP requires the first, most polluted, portions of wastewater to be cleaned separately. Since there is no requirement to clean 100 percent of the annual runoff, an UKOS-DV-RK distribution well may be used for the purpose that feeds the calculated amount of sewage to the purification system, while bypassing conditionally clean drains to the bypass channel. Using such a distribution well reduces the overall cost of equipment.

NOTE: the above complies with the «Provisional Recommendations on Designing the Facilities for Cleaning Surface Runoff from Territories of Industrial Enterprises and Conditions for Discharging it to Water Bodies» by VNII VODGEO.
Sampling well
The UKOS-DV-KK sampling well fitted with disk valve shall be installed for sampling the purified runoff upstream of the treated water outlet into the sewage system or terrain.
