Evaluación económica-ambiental, de la Planta de Tratamiento de Agua Potable, del cantón Francisco de Orellana, provincia de Orellana, para identificar y evaluar los aspectos ambientales y económicos, en el año 2015.

Abstract

The research and economic-environmental evaluation of the drinking wáter treatment plant was developed, in Francisco de Orellana village, Orellana province in order to identify and evaluate the environmental and economic aspects in 2015, the drinking water treatment plant current situation in the city was inspected and the environmental aspects identified; the estimated costbenefit, production, and disposition

to pay by the users of the drinking water was determined through surveys, matrices, records, field and literature research base on the INEN 1108 standard and Tulsma standard; lab materials technique charts, through which the results of the training processes, sand trap, flocculation, sedimentation, filtration and disinfection were obtained as well as the generation of sludge treatment which contain aluminium and other chemical coagulants, by using the sound level meter it was established that the noise pollution is 60 dB which is within the range of the annex V book VI of Tulsma standard, the permissible limits are 65 dB from 20h00 to 6h00 and 70 dB from 6h00 to 20h00. By using the Leopold matrix or cause and effect, it was determined that the treatment processes which produce more impact are chemicals dosing with moderate range, storage and cellar whith 3.0 moderate, sand trap 2.1 low, coagulants dosage 3.2 moderate and desinfection 2.9 moderate. The risks within the plant of drinking water are registered in impact charts by risks. The real production of drinking water was estimated in a cost of $1.07 per cubic meter, from that amount the Francisco de Orellana Municipality subsidizes 90% which is $1.00 and the user pays $0.07 for the service. The last step was to inspec the plant verifying the identified treatment processes, evaluating, valuing the aspects and environmental impact found, economic aspect inthe economic evaluation which determined the real production value of the drinking water. It is recommended that the plant managers implement the necessary improvement measures and the safety and health manual, maintenance plan.
