Abstract
Chicacao is located in the northern part of the department of Suchitepéquez, 151.1
km from the capital city by the CA-9 highway (Nahualate) and 25.4 km from the
departmental capital, Mazatenango. It has an approximate population of 56,018
inhabitants; the territorial extension of the urban helmet is 26 km ². According to
Holdridge, this territory is located between very humid subtropical forest (warm)
and humid subtropical forest (warm) forest zones.
Chicacao has three rivers, Mixpilla, Nahualate and Cutzán, whose waters are
contaminated by solid waste, such as: batteries, metals, plastic, dead animals and
sewage from homes.
The project to evaluate the discharge of wastewater from the urban area of
Chicacao, Suchitepéquez, consisted in identifying the pollutants contained in the
wastewater, discharged to the water tributaries, which allowed to elaborate the
technical study of the management of wastewater to, according to Government
Agreement No. 138-2017.
Fifteen download points located in the urban area of the municipality were
identified, which were georeferenced and placed on a map, for which the global
positioning system (GPS) was used in a GIS software. The flow was measured
during 24 hours and simple samples were taken to analyze the 19 parameters
established by the aforementioned agreement, a population growth projection was
made for the year 2037 and according to this data the flow to be treated for that
year.
In addition, a field investigation was carried out to identify the operation of the
septic tanks and the homes that are connected to them. It was found that most of
the homes are connected to the municipal sewerage system and that the
wastewater does not comply with the parameters of temperature, fats and oils,
floating matter, suspended solids and faecal coliforms as established in
Government Agreement No 138-2017.
The discharge flow of the 15 points is 0.8804 m³ / s and for the year 2037 it will be
1.6324 m³ / s, so it is recommended the construction of two treatment plants to
treat the 15 discharge points; one with a capacity of 1.1914 m³ / s and the other
with 0.4410 m³ / s capacity. |
