This study aimed to obtain the relative formula with the unit treatment cost according to the treatment of a sewage plant in the service area under highway. The following results were obtained. The correlative formula connected to amount of sewage(Q)generation was as follows ; between an annual amount of sale(C) showed Q=19.113C0.9294/, and between the number of users(P) showed Q=210-8/ P- 0.0298P + 75,666. The correlative formula connected to the treatment cost was as follows , according to the amount of sewage generation showed S= 310-6/Q 0-0.2266Q+29,895, according to the elimination of BOD(E) showed S=610-5/E-0.6717E + 27,744, according to the annual amount of sale showed S=0.0005 C-4.8013C + 35,118, with the number, of persons(P) using the service area showed S= 210-8/ P- 0.046P + 48,803.
