Water Treatment Plants
Since the potable water sources of Tonya district are insufficient and polluted, it is planned to take water with a new water intake structure on the "Fol" river on 8 km south of the town, for the demand determined according to year 2030 population projections. Project objective is to design a water treatment plant to treat raw water according to Turkish standard of TSE 266.
Water demand of the project in the target year of 2030 is 40 lt/sec.
In the water intake structure with screen on the crest, a settlement pond, spillweir and a washing channel was also designed for the Fol creek.
