Water Conservancy & Aquaculture Solutions

1.Industry Pain Points & Challenges

In canal water conveyance and aquaculture, water loss and environmental control are the biggest challenges:

(1) Severe seepage loss: Traditional earthen canals or damaged concrete canals have a water seepage rate as high as 40%-60%, resulting in a huge waste of water resources.

(2) Difficulty in water quality control: Earthen pond aquaculture is susceptible to contamination by soil bacteria and parasites, making pond cleaning difficult, and bottom sediment easily leads to a decrease in dissolved oxygen, affecting the survival rate of fish and shrimp.

(3) Structural instability and collapse: River channels or fishpond slopes are prone to collapse under the scouring of water flow, resulting in high maintenance costs.

2.Our System Solution

Changfeng’s “seepage prevention + stabilization + hygiene” solution:

(1) High-efficiency canal seepage prevention: Using composite geomembrane. This product is a composite of geotextile and geomembrane, providing both seepage prevention and strong puncture resistance through the geotextile surface.

(2) Ecological Aquaculture Barrier: Smooth HDPE Liner is used to lay the pond bottom. It not only completely isolates the pond from soil pollution but also has a smooth surface, allowing for rapid pond cleaning and significantly shortening the aquaculture cycle.

(3) Embankment Stabilization System: Geobags or gabions are used to fill the embankment with stones or soil, forming a flexible slope protection structure to resist water erosion.

3.Core Advantages

(1) Reduces Water Loss by 90%: The composite seepage prevention system minimizes water loss and doubles water resource utilization.

(2) Reduces Pond Cleaning Time by 70%: The HDPE membrane surface does not accumulate mud, facilitating aquaculture wastewater discharge and reducing pond cleaning time from several weeks to several days. (3) 20% Reduction in Overall Construction Costs: Compared to full concrete lining, the geotextile material solution offers 3 times faster construction speed and virtually zero post-construction maintenance.

4.Case Studies & Related Products

Typical Case: Seepage prevention project for a large-scale white shrimp farm in Southeast Asia, achieving a 30% increase in annual production.
