Lift Station Wet Well Design for EKAM Housing Project, Haiti

The project requires a comprehensive wastewater management system to ensure the health and safety of the residents. The design of the wastewater management system includes an intermittent sand filter, a lift station, and a submersible sewage pump. The intermittent sand filter is designed to treat the wastewater generated by the homes. The filter has a leaching area of 33,000 square feet, with two beds and a total leaching area of 16,500 square feet. The filter is designed to handle an average daily flow of 45,000 gallons per day (GPD), with a peak flow rate of 60 GPD per home. The filter is equipped with a top layer of crush stone, with a depth of 10 inches and an effective stone volume of 13,038 cubic feet. The lift station is designed to collect and transport the wastewater from the homes to the intermittent sand filter. The lift station has a wet well with a diameter of 13.92 feet and a length of 13.17 feet. The wet well has a volume of 412 cubic feet and a pump rate of 170 gallons per minute (GPM). The lift station is equipped with a check valve and a gate valve to control the flow of wastewater. The submersible sewage pump is designed to pump the wastewater from the lift station to the intermittent sand filter. The pump is a Goulds Water Technology WS-D4 Series pump, with a maximum capacity of 620 gallons per minute (GPM) and a maximum total head of 60 feet. The pump is equipped with a 300 Series stainless steel keyed shaft and a single row ball bearing. The pump is designed for continuous operation when fully submerged and has a maximum ambient temperature of 104°F (40°C) for continuous duty and 140°F (60°C) for intermittent duty. The wastewater management system is designed to meet the needs of the EKAM Housing Project in Haiti. The system is equipped with a comprehensive network of pipes and pumps to collect and transport the wastewater from the homes to the intermittent sand filter. The system is designed to handle the peak flow rate of 60 GPD per home and to provide a safe and healthy environment for the residents. The system is designed to operate within the following parameters: * Average daily flow: 45,000 GPD * Peak flow rate: 60 GPD per home * Maximum total head: 60 feet * Maximum submergence: 50 feet * Minimum submergence: Fully submerged for continuous operation * Maximum environmental temperature: 104°F (40°C) for continuous duty and 140°F (60°C) for intermittent duty
