This consultancy aims at supporting the Municipality of Guatemala City by providing different studies to help resolve the water issues it faces. Together with EMPAGUA; IFC has conducted a comprehensive review; and as a result; the following studies have been determined to be needed: A) La Brigada water treatment plant:* Objective: Enhancement of the La Brigada Treatment Plant through the diversion of tributaries in the Mixco and San Cristóbal area.* Expected impact: Incorporation of the capacity to receive water flow ranging from 30 to 50 liters per second.* Studies needed:o Topographical surveys of the components of the La Brigada System;o Hydraulic and hydrologic studies for the definition of water balance;o Study of the condition and status of the raw water pipeline from La Brigada dam to La Brigada plant;o Structural study of the components of the water purification process of the La Brigada plant. B) San Antonio Plant:* Objective: Enhancement of the treated water quality at the water purification plant.* Expected impact: Improvement of water quality; ensuring its flow and continuous operation.* Studies needed:o Soil study;o Topographic survey;o Water quality study;o Design of primary water treatment technology for 80 liters per second;o Structural design associated with water pretreatment. C) Hincapie Plant* Objective: Enhancement of the treated water quality at the water purification plant.* Expected impact: Improvement of water quality; ensuring its flow and continuous operation.* Studies needed:o Soil study;o Topographic survey;o Water quality study;o Design of primary water treatment technology for 60 liters per second;o Structural design associated with water pretreatment. D) Ojo de Agua Plant* Objective: Remodeling of the Ojo de Agua Pumping Station; which involves equipping it with updated technology and providing protection against leaks for the Ojo de Agua reservoir.* Expected impact: Preservation of the operation of the Ojo de Agua Plant and a potential increase from 150 to 200 liters per second.* Studies needed:o Soil study;o Topographic survey;o Design of pumping technology efficiency for the Ojo de Agua I booster pumping system;o Estudio del estado y condiciones de línea de conducción de agua de las líneas de 18 de Ojo de Agua a Tanque El Guarda; Zona 8;o Diseño estructural del tanque gemelo de compensación de 7500 m3. E) Canalitos Plant* Objective: Improve the quality of treated water.* Expected Impact: Enhancement of water quality; ensuring its flow and continuous operation to supply users in zone 18.o Studies needed:o Soil study;o Topographic survey. The technical specifications of each of the studies will be discussed by IFC; EMPAGUA and the Municipality of Guatemala City shortly after the signing of this engagement letter.
