Best Practices in Use of Package Treatment Plants

  • • Where public sewage systems are not available and where feasible, utilize a cost-effective package treatment plant, located in a flood-free zone, which meets the needs of the community, business, or industry, for the present and for the foreseeable future, instead of numerous on-site sewage disposal systems to prevent land and water contamination and provide a satisfactory effluent for disposal.
  • • Provide effective and continuous maintenance as well as operational capabilities; especially monitor wastewater flow, aeration, electronics, and equipment for the system.
  • • Dispose of biosolids in an appropriate manner.
  • • Frequently conduct tests to determine levels of BOD, total suspended solids, ammonia, nitrate levels, phosphorus, and E. coli and determine if they meet the standards established by the appropriate regulatory agency.
  • • Provide a standby generator in the event that the electrical source is disrupted.

Disinfection of Effluent

(See endnotes 54, 55)

A disinfectant must be used on the effluent from the wastewater treatment plant, from on-site sewage disposal systems where the effluent flows onto the ground and into a body of water, and if there are combined sewer overflows. The disinfectant must be able to penetrate and destroy the infectious organisms under normal conditions, be safe for use, storage, and shipping, and not leave toxic or mutagenic residuals.
