Pumping Stations & Diversion Wells

Structure

The packaged pumping station integrates a collection chamber, submersible pumps, inlet and outlet piping, guide rails, valves, level sensors, and an electrical control panel into a compact unit. The chamber is available in FRP, carbon steel, or stainless steel. Access covers, ventilation, and maintenance facilities can be configured to suit project requirements.

Operating Principle

Wastewater or stormwater enters the chamber through the inlet pipe. Level sensors signal the control panel to start the pumps when the liquid reaches a preset level and stop them when it falls to the preset stop level. For multi-pump stations, pumps can alternate to balance operating hours. Additional pumps, alarms, and remote monitoring are available as required.

Applications

• Municipal Sewer Networks: Lift and transfer sewage where gravity drainage is insufficient.
• Residential Communities: Collect and pump domestic wastewater from housing developments and apartment complexes.
• Stormwater Drainage: Collect and discharge rainwater from roads, underpasses, low-lying areas, and developed sites.
• Rural Wastewater Projects: Connect dispersed communities to centralized or decentralized treatment systems.
• Sewer Network Upgrades: Add pumping capacity where space is limited or rapid installation is required.

Key Features

• Integrated Design: Combines the chamber, pumps, piping, valves, and controls in a compact, prefabricated unit.
• Fast Installation: Prefabricated construction reduces on-site assembly work and supports shorter installation schedules.
• Compact Footprint: Suitable for underground installation, helping conserve surface space.
• Automatic Operation: Level-based controls start and stop pumps automatically according to incoming flow.
• Flexible Pump Arrangements: Multiple-pump configurations support alternating operation, standby capacity, and peak-flow demands.

Structure

The smart diversion well typically consists of a chamber, inlet and outlet connections, actuated gates or valves, level sensors, and an electrical control panel. Depending on the project, additional equipment may include rainfall sensors, flow meters, water quality sensors, and remote communication modules.

The chamber layout and flow-control equipment are configured to match the drainage network, site conditions, and required diversion strategy.

Operating Principle

Incoming water enters the chamber and is routed to the appropriate outlet by automatic gates or valves, based on sensor readings and preset control rules. In typical operation, dry-weather sewage flows to the wastewater network. During rainfall, polluted initial runoff can be diverted for treatment, while later stormwater may be sent to the stormwater network when conditions allow. Water-level, rainfall, flow, or water-quality sensors can guide diversion. Remote monitoring and manual override are available.

Applications

• Municipal Drainage Networks: Control wastewater and stormwater routing between designated pipelines.
• Initial Runoff Management: Divert polluted runoff at the beginning of rainfall events to collection or treatment facilities.
• Combined Sewer Improvements: Support controlled flow diversion for combined sewer management and upgrade projects.
• Residential and Commercial Developments: Manage drainage flows from communities, shopping centers, and mixed-use developments.
• Industrial Parks: Route site runoff and wastewater according to water characteristics and treatment requirements.
• Waterway Protection Projects: Support interception of sewage and polluted runoff before reaching receiving waterways.
• Drainage Network Upgrades: Add automated diversion and monitoring capabilities to existing infrastructure.

Key Features

• Integrated Design: Combines the chamber, flow-control equipment, sensors, and controls in a coordinated system.
• Automatic Flow Diversion: Adjusts gate or valve positions according to sensor readings and preset operating rules.
• Customizable Configuration: Chamber dimensions, materials, pipeline connections, and control strategies can be tailored to project requirements.
• Compact Footprint: Suitable for underground installation, helping conserve surface space.
• Flexible Control Options: Supports water-level-based control, with optional rainfall, flow, or water-quality-based operation.
• Optional Remote Monitoring: Enables operators to view operating status, receive alarms, and adjust settings remotely.
