Abstract
EDH-I-00-08-00027. The project aims to improve the water supply and sanitation infrastructure in Robertsport, Liberia. The population of Robertsport is estimated to be approximately 20,000 people, with a water demand of 1.5 million liters per day. The city's previous water system consisted of hand pump wells, which are not sufficient to meet the current demand. The water supply challenges in Robertsport include limited access to safe drinking water, inadequate water treatment, and poor sanitation practices. The master plan identifies several opportunities to improve the water supply in Robertsport, including the development of a groundwater supply system, the use of surface water from Fasa Creek and other small streams, and the implementation of rainwater harvesting systems. The plan also evaluates the water quality of the available sources, including physical, chemical, and bacteriological parameters. The water treatment options considered in the plan include chlorination, water treatment plants, and Robertsport's slow sand filtration process. Storage options include existing storage tanks, mini tanks/zonal nodes, and private tanks. The plan also evaluates the water distribution options, including a new distribution network and the use of independent electrical generator units, solar power, and wind power. The sanitation component of the plan assesses the current sanitation status of Robertsport, including the practices employed, generation rates for wastewater and night soil, and changes in generation rates as a result of the Liberia Municipal Water Project. The plan proposes several methods for addressing changes in sanitation status, including simple pit latrines, ventilated improved pit (VIP) latrines, twin pits for pour-flush latrines, septic tanks and soakaway systems, and centralized wastewater treatment options. The cost estimates for the project include short-term and medium-term costs, including capital costs, operating and maintenance costs, and long-term costs. The plan recommends a short-term project to establish a gravity-fed water system and to protect the Fasa Creek watershed, as well as a medium-term project to restore the water treatment plant and water system. The Robertsport Water Master Plan aims to improve the water supply and sanitation infrastructure in Robertsport, Liberia, and to provide a sustainable solution to the city's water challenges. The plan provides a comprehensive analysis of the water supply and sanitation situation in Robertsport and proposes several solutions to address the challenges faced by the city. The plan's recommendations include the development of a groundwater supply system, the use of surface water from Fasa Creek and other small streams, and the implementation of rainwater harvesting systems. The plan also recommends the use of independent electrical generator units, solar power, and wind power to provide energy for the water treatment and distribution systems. The sanitation component of the plan recommends the use of simple pit latrines, ventilated improved pit (VIP) latrines, twin pits for pour-flush latrines, septic tanks and soakaway systems, and centralized wastewater treatment options. The plan also recommends improving hygiene behavior and sanitation practices through education and awareness programs. Overall, the Robertsport Water Master Plan provides a comprehensive solution to the city's water challenges and aims to improve the water supply and sanitation infrastructure in Robertsport, Liberia.
