Rainwaters in the AVAS area can be divided into two distinct parts. One is the Avas roof and its surroundings located in the higher zone of Avas, an extensive public park with roads. The other part is the area of Avas, which is situated on a hillside and is built mainly for cellars and the public roads supplying them. (Annex 1: At present, the rainwaters of the upper zone cross the built-up area in an unordered manner, so with different, often unreliable technical solutions, sudden rainwaters reach the road surfaces that are limited or barely fulfilling drainage functions. Deficient passages and their installation in deeper areas hinder the flow of stratified waters, and bloating water (torlas water) creates a direct risk of slipping due to unfavourable subsoil conditions. A key element of the development proposal is the diversion of rainfall in two areas. The rainwaters coming from the upper zone (“mountain roof”) are to be collected by means of a belt trench system above the built-up area, while the rainfall falling to the lower zone (“mountain side”) is transmitted to the receiving urban rain canal network and then to the Szinva stream by building an open rainwater drainage network. It is our idea that rainwaters from the top of the mountain should be transferred as quickly as possible to the hill-foot environment, and it is appropriate to establish some possible routes where the quickest drainage of water is to be solved by appropriate energy-breaking barriers, surrants, drift-reducing clumps (water chests), butt thresholds. According to our observations, the natural surface drainage recesses and ravines were mainly formed where there is a larger fracture or a projection crossing the layers of the hillside. In the case of an adequate level of surface drainage, the number of cellar grazings and periodic runoffs in the cellar observed in the respective break-off zones and the amount of water entering it may be minimised. As a first step in planning, we have defined the bays of the planning area and the catchment areas of each bay. A total of five bays have been set aside with the corresponding sub-basins, taking into account the possibilities to connect to the urban rain canal network. Due to the geological structure of the area and the built environment, significant water retention is not possible, but all water retention works, water trunks and mines are used for water retention. As the design area is characterised by high-fall steep slopes, a major issue was the right energy break, damping and, above all, the solution of sediment capture. The planned technical solutions are intended to address this in the light of scarce technical possibilities. Due to narrow streets and public utilities in several places and construction difficulties, we are planning to develop a water drainage. We planned to build closed canals only on the mountain legs, where it was justified and possible. The structure of the Vápa (central or wind-led vat) was determined by the existing public utilities, the possibility of ordering later public improvement, and the situation of the properties (possibility of insurance for connections). The planned vats are 0.8 m wide and 10 cm deep, placed in concrete in the line of the cart (0.8 m width), the casing and vat are incorporated with resin or antifreeze concrete grout. The planned energy-breaking and sediment grip thresholds are 7 cm high and 1 m wide in height and 1 m wide in the form of high-speed structures made of casing material. We designed the design of the speed police-like energy-breaking and sediment grip structures next to the planned priority border, so that the drainage surface is also suitable for the drainage of rainwater without flooding the surrounding areas, taking into account the significant rainfall water that is drawn up. The points of access are as follows: • Bay I: Papszer — Rákóczi út 40/60T and 60/90 T channel • Bay II: Ferenc Földes — Papszer — Szemere út 50/75T and 60/90T • Bay III: The canal near the church of Avasi is the DN 300 concrete canal crossing the Uitz B. road • Bay IV: Channel 30/45 and 40/60T • Bay V: To be introduced into the receiving Szinva stream, it is necessary to increase the capacity of Reményi Street from the existing sewer network and to build the Görgey — Corvin Road link (Detailed content in Annex 7: Quantitative presentation of the planned implementation.) The implementation of the project is not expected to cause climate risk. The design and implementation of the project complies with all environmental and equal opportunities legislation, the use of energy and the ecological status of the environment, the status of the water, and no climate change.
