Important Design Considerations for Basin Collection Troughs

When designing a water or wastewater treatment plant in Bethel, OH, it’s important to pay special consideration to how you design the basin collection troughs that will be used throughout the facility.

Here are a few of the most important considerations for you to take into account as you’re getting started on your plans.

Maximum flow rate

You need to make sure you design each collection trough in such a way that it will handle maximum specific flow rates. All of the basin collection troughs throughout the facility must be sized properly to ensure the hydraulics in the troughs do not negatively affect the unit process functions and designs.

Proper design of these troughs helps prevent flooding in the weirs. If flooding in the weirs were to occur, the hydraulics in the basin could lack continuity, resulting in negative outcomes of the individual unit process. Every basin requires different arrangements for collection troughs based on their designated application, so it’s smart focus on ensuring each will allow you to meet the maximum flow rate for their designs.


Troughs need to be the proper size to prevent swelling of costs. A trough that is much too large would increase the total cost of a project. A trough that is too small, meanwhile, could adversely affect the process, resulting in inefficiencies that could also increase the total cost of the project.

Keeping the trough at the correct sizes will create greater efficiency and reduce the costs associated with the process.

Potential extensions

Treatment facilities are often planned as extensions of existing facilities and installations. Many treatment facilities are placed on or next to a receiving body of water, which results in the outfalls being set based on the existing water level of that body of water. Outfall conditions can affect upstream unit process basins, which could either set or limit the head that is available to them.

If there are no issues with head in the treatment plans, collection troughs can discharge the water into an outlet channel. The water level going into the outlet channel will be close to a critical depth. It is important to calculate these depths and water levels upstream to ensure you get the most economical design possible for your basin collection troughs.

As you can see, collection troughs have a significant bearing on the processes used at the facility and the economics with which these processes occur. Proper design of these collection troughs can make or break the viability of the process.
