Zavoljo vedno večje pozidanosti okolja, ki prepustna tla spreminja v neprepustna, in pogostostih ekstremnih vremenskih dogodkov z intenzivnimi nalivi prihaja do povečanega površinskega odtoka padavinskih voda z utrjenih površin, ki se steka v obstoječe kanalizacijske sisteme. Zaradi tega so ti sistemi za današnje razmere poddimenzionirani, saj ne zmorejo več prevajati takšnih količin odtoka, kar povzroča nastajanje poplav. Pri odvajanju padavinskih voda s cest je dodatna težava, da se še dandanes voda, ki je velikokrat neprečiščena in obremenjena z onesnažili, z njih odvaja v kanalizacijske sisteme in nato v odvodnike. Takšen način odvodnje ni v skladu z veljavno zakonodajo in okoljevarstveno politiko, ki stremi h kontroliranemu zajemu padavinske vode in njenemu čiščenju pred iztokom v recipiente z namenom zmanjševanja obremenitev na okolje in izboljšanja njegove kakovosti. Z obzirom na zgoraj omenjeno problematiko bosta v diplomski nalogi za odsek javne ceste v naselju Rogoznica v občini Ptuj, ki ne ustreza trenutni zakonodaji, izdelani variantni rešitvi odvodnje padavinskih voda v skladu s trenutno zakonodajo in okoljevarstvenimi zahtevami. Nazadnje bosta rešitvi ekonomsko primerjani. Na podlagi primerjave je bila izbrana optimalna rešitev. Due to the increasement of structures being built in our environment, which turns permeable soils into impermeable ones and regular extreme weather events with intense downpours, there is an increase of surface runoff of rainwater from hardened surfaces, which flow into existing sewer systems. Because of this these systems are undersized for today's situation, as they are no longer able to regulate such amounts of runoff, which causes floods. The same problem occurs when draining rainwater from roads. An additional problem here is that even today, unfiltered water from them is often discharged into sewage systems and then into drains. Such a method of drainage is not in accordance with the legislation and environmental policy, which seeks to control the collection of rainwater and it's treatment before it's discharge into respective recipients in order to reduce the burden of untreated water and improve the environment. Regarding these issues, the thesis of the work presents alternative solutions for rainwater drainage for a section of a public road in the settlement of Rogoznica in the municipality of Ptuj, which does not comply with the current legislation and environmental requirements. Lastly, the two solutions will be compared economically and based on this comparison an optimal solution will be selected. |
