Ureditev odvajanja in čiščenja odpadnih voda območja naselja Dobovec

V diplomski nalogi je predstavljeno teoretično ozadje o odvajanju in čiščenju odpadnih voda, torej splošno o kanalizacijskih sistemih in čistilnih napravah. Za naselje Dobovec pri Rogatcu, ki se nahaja ob vodotoku Sotla, se v nalogi predvidi nov kanalizacijski sistem, ki bi zamenjal trenutno že obstoječe pretočne in nepretočne greznice, ki slabo vplivajo na okolje. Predvideva se gradnja ločenega kanalizacijskega sistema, kjer se odpadno vodo odvaja ločeno od padavinske. Novi kanalizacijski sistem se zaključi s malo membransko čistilno napravo, ki zagotavlja ustrezno čiščenje odpadne vode, saj se ta nahaja v zaledju zadrževalnika Vonarje. Prav tako se poišče tudi rešitev za odvajanje padavinske vode, in sicer se predpostavi, da se obstoječe greznice preuredijo v zadrževalnike padavinske vode. Padavinska voda iz cestišč preko sistemov cevi in odprtih kanalov ponika v vodotok Sotla. Za novi kanalizacijski sistem je izdelan tudi načrt poteka kanalizacijskega sistema in vzdolžni profili. The thesis presents the theoretical background on waste water discharge and treatment, that is general information on sewage systems and treatment plants. For the town of Dobovec pri Rogatcu, which is located next to the Sotla watercourse, the thesis anticipates a new sewage system that would replace the currently existing flowing and non-flowing septic tanks which have a bad impact on the environment. The construction of a separate sewage system is planned, where waste water is discharged separately from rain water. The new sewage system ends with a small membrane treatment plant which ensures adequate treatment of waste water, as it is located in the hinterland of the Vonarje reservoir. A solution for the drainage of rainwater is also sought, namely, it is assumed that the existing septic tanks will be converted into rainwater retainers. Rainwater from roadways sinks into the Sotla river through pipe systems and open channels. For the new sewerage system, the flow plan of the sewerage system and longitudinal profiles have also been prepared.
