Introduction: In this article, we will explore a unique solution to combat the high water situation experienced in a specific location. We will dive into the design, functionality, and components of a water intake system that utilizes a spinner screen. Additionally, we will discuss the downstream system, electrical components, and the generation of electricity. By the end of this article, you will have a comprehensive understanding of this imperfect yet functional system.

The High Water Situation

The first challenge faced in this particular location is the high water level. The creek is running three or four inches above normal, causing concern for the intake of water. To mitigate this issue, sandbags and rocks have been strategically placed to control the volume of water entering the intake line. Despite the turbidity of the water, the existing setup successfully manages the water flow.

The Intake Line and its Components

To ensure an efficient intake process, a two-inch intake is used in conjunction with a six-inch intake line. The water flows from the intake down to an elbow and a gravel trap. The gravel trap serves the purpose of cleaning out any debris that may accumulate. From there, the water continues its journey through the intake line, ultimately leading to the intake screen.

The Spinner Screen

The spinner screen plays a crucial role in the filtration process. It is designed to handle the debris brought in by the water flow. The spinner screen, equipped with golf ball bearings and a pin, effectively distributes the debris evenly, preventing any clogging or blockage. With its sturdy construction and optimal functioning, the spinner screen successfully separates the debris from the clean water.

The Overflow and Reservoir Tank

In times of high water, an overflow system is employed to regulate the excessive water. This mechanism ensures that the spinner screen does not become overwhelmed, consequently affecting its performance. The overflow helps maintain the integrity and functionality of the entire system. From the overflow, two four-inch lines extend 500 feet downstream to the nozzles for the turbine, initiating electricity generation.

The Downstream System

The downstream system plays a critical role in harnessing the water's energy. It involves crossing the creek with the support of cables and trees, ensuring the pipes are held securely in place. The use of different pipe materials, such as schedule 20 and schedule 40 PVC, helps maintain pressure levels and even water distribution. The system eventually leads to a small stream crossing, where a similar setup is implemented with four two-inch lines.

The Nozzle Housing and Turbine Wheel

Within the nozzle housing, the four two-inch lines converge into a four-nozzle housing, effectively feeding into the turbine wheel. This turbine wheel, known as the Harlington Grinspoon 22 wheel, is specially designed for electricity generation. It utilizes the power of the water flow to generate approximately 500 watts at full capacity.

The Electrical Components

The generated electricity is harnessed and managed by a series of electrical components. The rectifier converts the alternating current (AC) produced by the turbine into direct current (DC), which is then stored in batteries. An inverter transforms the DC power back into AC, enabling its utilization. The system also incorporates a control and monitoring system, allowing for efficient management of power consumption.

Conclusion

In conclusion, despite its imperfections, the implemented water intake system with a spinner screen provides a sustainable solution to the high water situation. By effectively managing the water flow, filtration, and electricity generation, this system showcases the ingenuity and resourcefulness of its design. While there may be room for improvement, this system serves as a testament to the possibilities of harnessing natural resources for sustainable energy production.
