Composite Slow-Release Overflow Well

Product Description

Dimensions    315 mm

Features      Impact-resistant; Weather-resistant / Corrosion-resistant

Functional Description

Collected rainwater is filtered through a cast-iron overflow manhole cover and an integrated debris-catching basket.

The cleansed rainwater is then recharged into the groundwater via an infiltration well, thereby safeguarding the natural ecological balance and fulfilling the objectives of “Sponge City” construction.

Type         Circular

What are the application scenarios for the Compound Controlled-Release Micro-Overflow Outlet?

The 315 Compound Slow-Release Micro-Overflow Core is utilized in Sponge City Low Impact Development (LID) facilities and for the retrofitting and upgrading of drainage systems. Adaptable to a wide range of scenarios, it provides precise flow control, slow-release peak shaving, facility protection, and overall system safety.

Core Application Scenarios: 1. Sunken Green Spaces / Bioretention Facilities: Prevents waterlogging and plant damage while stabilizing the soil.

Facilitates overflow during heavy rainfall events while simultaneously enhancing infiltration and water purification. Suitable for pipelines with a diameter of 315mm, with corresponding flow rates.

What are the application scenarios for composite controlled-release micro-overflow outlets?

1. Rain gardens/vegetated swales: Control discharge rates to prevent rapid overflow and wasted storage space, ensuring purification and infiltration efficiency.
2. Green roofs/roof gardens: Precisely control drainage, extend water storage time, optimize irrigation, reduce building load, and are suitable for refined management of small flow rates.
3. Infiltration trenches/drainage pipe nodes: Serving as intelligent inlets and outlets, they can alleviate peak flow, coordinate upstream and downstream pipe networks, and prevent instantaneous overload.
4. Wastewater tanks/ecological ponds: Precise water level management, phased and gradual release, improving water storage utilization rate and operational safety.

What are the application scenarios for composite controlled-release micro-overflow outlets?

6. Renovation of old residential areas/municipal pipe networks: Low-cost intelligent nodes rapidly enhance the ability to cope with extreme rainfall, compatible with 315 specifications, and enabling rapid connection.
7. Landscape water bodies/artificial wetlands: Water level and flow control to prevent overflow and drought, adapting to microflow and ecological management.
8. LID facilities within road red lines: Connecting road drainage with surrounding sponge city construction facilities to control runoff, reduce pollution, and protect the roadbed.
