BRIEF DESCRIPTION

This document is a thorough framework for regulating rainwater and wastewater outflow. In order to provide ecologically responsible water management throughout campus facilities, it provides system specifications, sustainability-focused solutions, combining system functionality with SDG-aligned practices to minimize environmental impact.

1. System Description

Effective water management is crucial to AASTMT's commitment to sustainability and achieving SDG 15. The sewage plant and rainwater system at Abu-Qir, Alexandria, is designed to handle wastewater and rainwater from specified areas, excluding student housing, hotels, presidential buildings, and restaurants.

2.  The drainage network

 Extending between these buildings and reaches the wastewater and rainwater collection pit located behind the buildings of the College of Architecture and Computers. Through a slope line with a diameter of (12 inches) and the current cesspool with dimensions of (2 x 2 meters).

3. Sump Specifications:

• Dimensions: The main sump has a 12-inch diameter and measures approximately 2x2 meters.
• Storage Capacity: With an effective storage capacity of around 12 cubic meters, the sump can handle high inflows during peak times and heavy rain events.

4. Pump Room Specifications:

4.1. Submersible Pumps:

• Quantity: Two submersible pumps by EBARA.
• Horsepower: Each pump operates at 10 horsepower.
• Flow Rate: Discharges water at 60-70 cubic meters per hour.
• Self-Priming Horizontal Dry Pumps
• Quantity: Two additional Siemens dry pumps, each with 15 horsepower, offering self-priming capabilities and reliable backup.

        5. Battery and Valve Configuration 

• Battery System: Features five outlets, each 12 inches in diameter, providing flexibility in discharge regulation.
• Valves:
• Check and Shut-off Valves: Include four 4-inch and one 6-inch check valves, and a matching set of shut-off valves, allowing for precise flow control and isolation during maintenance.

     6. Control Room and Electrical Panels

• Control Panels: Two electrical control panels manage pump operations and discharge flow, ensuring optimized, safe operations.
• Backup and Monitoring: Redundant control mechanisms minimize the risk of overflow or discharge issues, promoting reliability.

    7. Wastewater Network and Outflow Connections

• Pipeline Dimensions: The network starts with a 12-inch diameter line tapering to an 8-inch diameter before connecting to the main external discharge line.
• External Discharge Line: Wastewater is channeled to an external drainage system, aligning with local standards for safe water discharge.

    9. Control and Monitoring System:

• Control Room: Houses two electrical control panels that manage pump operations, discharge flow, and real-time system monitoring.
• Redundant Systems: The dual control panel setup ensures that, in the event of a failure, one panel will maintain functionality to prevent overflow or other discharge issues.
• Pressurized Outflow: The discharge line begins with an 8-inch diameter that transitions to 12 inches, connected to the main external drainage line. This configuration supports continuous pressure to facilitate wastewater movement and ensure compliance with local drainage standards.
• Contract with company (workers and Plumbers) that is contracted and is selected from among a group of companies in order to carry out cleaning and disinfection work for all the pump rooms on a daily basis to ensure that no blockage occurs in the pipes that could lead to leakage.

     10. Operational Guidelines and Maintenance Standards:

• Routine Inspections: Conduct bi-annual inspections of sump, pump room, and valve configurations to ensure optimal performance and compliance with safety and environmental standards.
• Discharge Quality Monitoring: Regular testing of discharge water for pH, turbidity, and pollutant levels to ensure alignment with environmental regulations.
• Seasonal Adjustments: Adjust discharge operations based on seasonal rainfall patterns, aiming to prevent overflow and maintain a balanced ecosystem impact.
• Emergency Protocols: the design of two electrical control panels manages pump operations and discharge flow, ensuring optimized, safe operations.
• Develop response plans in case of pump failure or overflow events, including staff training on spill containment and mitigation measures.
• Stakeholder Engagement: Regular workshops and collaborations with environmental organizations to promote sustainable water practices and utility company Abu Qir Ash Sharqiyah, Alexandria.
