—a) The objective of the project, planned professional/technical results: Development of the existing rainwater network in the inner area of Kiskőrös town, addition of new rainwater collection and drainage network, as well as water retention of collected rainwater and the establishment of a reservoir. As a result of the development, problematic sites (affected by inland water protection preparedness, havaria situation) will be eliminated, the sewer network will form a coherent network and will be able to drain the affected part of the settlement. The purpose of the planned reservoir is to maintain the majority of the rainwater in the area, to contain it and to contain it locally, so that only excess water is drained, so that the recipient is less burdened and, on the other hand, the management of surface and groundwater resources can be facilitated: if the reservoir is filled, the groundwater replenishment is ensured, but if the reservoir is excreted or has an evaporative loss, the groundwater inflow is possible, thus the regulation of the groundwater level can be managed. (B) 3.1.1. The technical and technical content of the project by presenting the selected self-eligible activities: (AB) Description of the planned rainwater channel: Channel CS 1-0-0 The Dózsa György: The route of the planned rainwater drainage channel is shown in the site plan attached to the study. In Dózsa György street there is an open rainwater drainage system with covering elements. Currently, rainwater drainage is carried out with ground trenches and closed canals, the aim is to bring these ditches to the right level and to cover them, and to replace damaged frame elements. The perimeters are constructed from 100x100 frame elements. On Dózsa György Street, after the connection of the Sáhor rain canal, it is necessary to extend the channel 89.0 m in length, which takes place with a concrete tube with a diameter of DN 600. Channel CS 2-0-0: (M. Hrúz, Tompa M. Street): The route of the planned rainwater drainage channel is shown in the site plan attached to the study. The current open rainwater drainage system in Tompa Mihály Street is dangerous for accidents, therefore the construction of a closed canal is the right solution, which is carried out with a DN 1200 diameter concrete pipe. Channel CS 3-0-0: (Klapka street) In this section of Klapka Street (Spring — Bem u.) there is currently a closed rainwater drainage channel, whose elevation line and different diameters are not suitable for draining high-intensity precipitation, therefore the existing channel needs to be reconstructed. The route of the planned channel is the same as that of the existing channel and the cleaning shafts are placed in the same location. The rain canal, which is made of NA 60 concrete pipe, is designed to take into account the location of concrete cleaning shafts with NA 80 casting cover. The casing of the sewer cleaning shafts 3-0-0 is closed. Existing lattic condensed cleaning pits in the road, not affected by the planned sewer, shall be connected at an existing level. (BA) Designed reservoir: The Sáhor canal is unable to transport rainwater falling into the catchment area in case of high water levels, therefore it is necessary to build a reservoir and a bridge of rainwater. The reservoir is capable of storing the suddenly fallen rainwater, when it is no longer possible to store additional water from gravity, the gravitational side is blocked, so it is not possible to swell back the rain canal, and the pump in the overflow shaft pushes the water into the rainwater reservoir. The section of the channel in front of the reservoir will be rebuilt with DN800 HÓDCSŐ. On the gravitational side, a DN 100 betomac and a HODAKNA are placed with a steel ban, from the DN100 betomac with a concrete channel DN500 to the planned Wum 280/280 crossing shaft. 2 DN 250 KPE pipes will be installed between the shaft and the interlocking pit 1.0 m. After the coding pit, a 13.9 m long DN 300 KM — PVC pipe is installed, which raises the rainwater into the rainwater reservoir to the right level. Data of rainwater reservoir: — Operational water level in the case of gravitational introduction: 98,24 mBf — Operating water level in case of depressed discharge: 99.48 mBf — Bottom level: 97,48 mBf — Storage volume for gravitational introduction: 20 318 m³ — Storage volume in case of depressed discharge: 53 468 m³ — Effective storage volume: 66 835 m³ The level of the rainwater reservoir can be controlled by means of a draining artifact. An O80 estuary preface is installed in which two rows of inserts are installed. The height of the pads can be used to control the water level. Further details can be found in chapter 4 of PET.
