This document provides technical recommendations that both systems and primacy agencies can use to comply with Lead and Copper Rule (LCR) corrosion control treatment requirements and to evaluate and designate optimal corrosion control treatment (OCCT) more effectively. The appendices include OCCT evaluation templates that can be used to organize data and document decision-making. For added customizability and convenience, these templates are also availabile in a spreadsheet format.

Septic tank effluent FM discharge to gravity sewer - Odor control?

Epa Optimal Corrosion Control Treatment
I expect that given it is septic tank effluent to begin with in a small diameter collection system that sulfide generation will be excessive and will cause a significant odor problem at the discharge point.
I have considered a few options at this point. The first is to detain/equalize some of the effluent and aerate it prior to repumping it to the discharge point. The cons of this idea are:
1. One of the nice features of the STEP system is that there is limited need for redundancy/fail safe at each of the STEP tanks at each residence. However, once I detain that flow somewhere I need to remump it with larger pumps, backup generators, etc. It adds a significant 'mission critical' aspect to the project. There is also the potential for odor generation at this site which would have to be mitigated as well.
2. I have no means of quantifying the amount of sulfide generation to expect. I have a feeling that the amount of sulfide generated is going to vary significantly throughout the day. Also, while I have found a great deal of information in the EPA Design Manual Odor and Corrosion Control in Sanitary Sewerage Systems and Treatment Plants, it mainly deals with the prevention of sulfide formation, not reduction of existing sulfide. This makes design and sizing of this system difficult. Due to the uncertainty involved it will be easy to spend way more money than is actually necessary to solve the problem.
Another idea I have considered is hydrogen peroxide injection prior to discharge. This idea has merit because it is easily scalable to match the actual treatment requirements of the effluent after the system is brought online and can be metered based on the flow rate of the effluent. However, it is a hazardous substance which will require specialized facilities. It will also add a significant cost to the operation and maintenance of the STEP collection system.
I am looking for any alternative ideas others might have or for any insight on the concepts I am considering.
