Soritor is a little city located in tbe Peruvian Amazonian, in the Region of San Martín, with a population of 10000 inhabitants approximately. Her sewer facilities has a stabilization pond scheme which is object of investigation present. Were founded parameters than let to test the purifying efficiency and bacterium death obtained from sewage purify plant (SPP) of Soritor. The results show that the SPP haven't minimum structures for a good performance. The average faecal coliform concentration of effiuent (5,4E+o4 NMP/lOOml) is bigger than permissible limits according to General Law of Water and bis bylaws, likewise global treatment efficiency (99,9168 %) is relatively poor. The average faecal coli concentration of receiver water body before discharge point has a bigger concentration (2,2E+o5 NMP/lOOml) than treated sewage effiuent, therefore considerations about to decrease this parameter by these ecosystem is not possible through dilution. Was founded bacterium death velocity (0,44 Vd) for be used as a design and optimizing parameter for SPP's stabilization ponds or future another in the region, through tests in discontinued flow, according Chick's Law, carried out in a facultative first pond. Also was founded the hydraulic dispersion factors for both, primary and secondary ponds, (1,3 lid and 0,98 l/d respectively) with relation to pond geometry, according with first arder equations and mathematic models developed for Yañez (1983). Finally, with respect to results founded and appraised was made a technical proposal in order to improvement and optimize the Soritor's SPP, according with Norm S.090 called Norm of Sewage Treatment Plants ofthe National Construction Regulations and the Law Nº 17752 called General Law of Waters and her bylaws.
