Cost Passive Intake Screens with simple design reducing civil works and equipment expenses while ensuring water delivery
Product Description:
Oasis Passive Intake Screens are engineered to provide uninterrupted water withdrawal from lakes, rivers, and oceans at a low, uniform velocity. With a fixed diameter of 800 mm and customizable length to suit your specific project requirements, these screens offer a reliable, cost-effective, and environmentally friendly solution for both freshwater and seawater applications.
Constructed from high-quality stainless steel (various grades available upon request), the intake screens are designed to resist bio-fouling and corrosion, ensuring long-term performance with minimal maintenance. Whether for industrial cooling, municipal water supply, or agricultural irrigation, our passive intake screens deliver consistent flow while protecting aquatic life.

FAQ
1. What is the difference between passive intake screens and conventional water intakes?
Passive intake screens operate without moving parts, drawing water at a very low and uniform velocity. Unlike conventional water intakes, they significantly reduce fish impingement and debris entrapment, making them ideal for environmentally sensitive projects, including municipal water treatment and irrigation systems.
2. Can your 800 mm passive intake screens be used for both seawater and freshwater applications?
Yes. Our intake screens are available in various stainless steel alloys (e.g., 304, 316L, duplex), providing excellent corrosion resistance for seawater, brackish water, and freshwater. They are widely used in power plants, desalination plants, municipal water treatment facilities, and agricultural irrigation systems.
3. How do I determine the required screen length for my project?
The length of our 800 mm diameter water intakes is fully customizable based on your site conditions, such as water depth, flow rate, and debris loading. Our engineering team can help you calculate the optimal length to achieve low slot velocity and uniform flow, ensuring reliable performance for irrigation systems or municipal water treatment plants.
4. What maintenance is required for passive intake screens?
Because our intake screens have no moving parts and are made of bio-fouling resistant stainless steel, maintenance is minimal. Occasional inspections and cleaning (if debris accumulates) are sufficient. This low-maintenance design reduces operational costs for long-term applications, including remote irrigation systems and continuous municipal water treatment operations.
5. Are passive intake screens environmentally friendly?
Absolutely. Our water intakes are designed with very low slot velocity (typically <0.5 ft/s), which prevents fish and aquatic organisms from being drawn against the screen surface. They meet stringent environmental regulations and are the preferred choice for eco-friendly projects, from municipal water treatment to agricultural irrigation systems
