Measure and Control Water Flow to Help Minimize Environmental Impact, Public Safety Risks, and Infrastructure Damage

Measure and Control Water Flow

Flumes are used to measure and control the flow of water, helping to manage stormwater and wastewater in a treatment plant. effectively and prevent flooding, erosion, and water pollution.

Monitor Water Quality

They are used in stormwater management to monitor flow rates, regulate discharge, and manage sediment and debris in the system.

Precise Flow Measurement

Flumes are equipped with staff gauges, ultrasonic sensors, pressure transducers, and electronic totalizers to measure and record flow data.

Corrosion-Resistant

Durable construction materials include stainless steel, fiberglass, or lined precast concrete to resistant corrosion and wear.

Added Safety Features

Safety features include slip-resistant platforms, OSHA-approved ladders, safety nets, and ventilation.

Variable Flow Rate

Stormwater flumes can accommodate various flow rates from 1 CFS to 25 CFS.

Details

Stormwater flumes are used in various applications to measure and control the flow of water, helping to manage stormwater runoff effectively and prevent flooding, erosion, and water pollution. Some common applications for stormwater flumes include urban drainage systems where they monitor and regulate stormwater drainage networks including water flow from streets, parking lots, and other impervious surfaces. Flumes are just as useful in water treatment plants to measure and control the flow of stormwater and wastewater, ensuring proper treatment and discharge; and in agricultural settings, where they help manage stormwater runoff and irrigation water, preventing soil erosion, nutrient loss, and water pollution.

ParkUSA manufactures flumes in many styles including the Parshall, Palmer-Bowlus, or H-Type design to offer precise flow measurement. A state-of-the-art control system can be incorporated into a flume system to automatically measure and monitor the flow rate. This enables real-time data collection and analysis, helping to optimize stormwater management and facilitate timely decision-making.

How It Works

A wastewater or stormwater open-channel flume is designed to measure the flow rate of water passing through an open channel or pipe. It can be provided with various flow monitoring devices such as staff gauges, ultrasonic sensors, pressure transducers, and electronic totalizers. Our flumes are built within a precast concrete structure that houses the flume and provides an interior platform. The structure supports direct burial and enables seamless inlet and outlet pipe connections, ensuring proper flow management and measurement within the system.

ParkUSA flumes incorporate additional features to enhance their capabilities and ensure a comprehensive and efficient solution for optimizing stormwater or wastewater management practices. Accurate flow measurement, versatile flume types, minimal maintenance, robust construction, precast concrete housing, and an automated control system offer an ideal solution for a wide range of water management applications.

Models

About the Pashall Flume

Invented by Ralph L. Parshall, these flumes are versatile and widely used for measuring flow rates in open channels. Parshall flumes have a distinct U-shaped cross-section, a converging section, a throat section, and a diverging section. The flow rate is determined by measuring the water level upstream of the throat section. Parshall flumes are self-cleaning and perform well in sediment-laden water.

Applications

Wastewater and stormwater flumes accurately measure and control water flow to help minimize environmental impact, public safety risk, and infrastructure damage.

Water Treatment Facilities

Flumes are used in water treatment plants to measure and control the flow of stormwater and wastewater, ensuring proper treatment and discharge.

Industrial Sites

Flumes can be used at industrial facilities and treatment plants to measure and control stormwater runoff and control the movement of wastewater through the treatment process.

Urban Drainage Systems

Flumes are installed in stormwater drainage networks to monitor and regulate the flow of water from streets, parking lots, and other impervious surfaces in urban areas.

Agricultural Fields

In agricultural settings, flumes help manage stormwater runoff and irrigation water to prevent soil erosion, nutrient loss, and water pollution.

Road and Highway Drainage

Flumes used along roads monitor and control the flow of stormwater runoff to prevent flooding and maintain the structural integrity of the roadway.

Construction Sites

During construction projects, flumes are used to manage runoff and prevent sediment, debris, and pollutants from entering nearby water bodies.

Watershed Management

Flumes help protect water quality, prevent erosion, and maintain healthy ecosystems within watersheds.

Flood Control Structures

In flood-prone areas, flumes are integrated into flood control structures to measure and regulate water flow, reducing the risk of flooding.
