MESSCO-USA, INC. Lift Station Program
Lift stations and pump stations are usually located at the lowest point within the collection system. Flows from gravity lines feed the lift stations then transfer the waste water either to another lift station or to the highest point and begin the process of gravity flow to the next lowest level in the collection system. Proper operation of all lift stations is critical since it is hazardous waste and its’ operation is strictly controlled by the EPA and state and local government agencies.
Grease and odors at lift stations come from a combination of all the waste and organics that accumulate upstream and, ultimately, end up in the lift station. Eventually all this wastewater is transferred along a collection of small and large concrete pipes and end at the waste treatment plant for processing. In many cases this collection system also produces large amounts of odors and these concrete pipes are subject to corrosion from the gases produced and can become damaged to the point they need replacement. There are several factors that contribute to odors, but the greatest and most challenging issue is when low flows are present. Low flows allow the organics to build up producing the hydrogen sulfide (H2S) odors. These odors are usually located within the lift station or at the location where the waste stream exits the force main and continue into the collection system.
Since a single solution to control odors at all lift stations is not realistic, we inspect, monitor and service lift stations frequently during the initial few months of service to determine what type of treatment is most effective. The following are the different treatments we implement on a monthly service schedule to control odors at lift stations:
Chemical, biological, and encapsulation dispensing upstream and/or at the lift station
Aeration, misting, fogging and/or masking of odors at the lift station
We also offer odor logging services where the client can request odor logs at each lift station where the H2S odors can be logged over a specific time duration. This will allow the Client to understand the severity of the odors escaping and evaluate the effectiveness of the different treatments being implemented.
The monthly service program is billed monthly and odor logging is billed separately where the cost varies based on the scope performed. We encourage the client to engage in a one-year contract initially so that we can evaluate the changes in your system throughout the different seasons.
We currently service several municipalities and food establishments throughout Tennessee and Nevada using a combination of the above treatments.
