Wastewater Treatment 101: Disposal by Dilution

  2. 2. Introduction • A California-based environmental engineering company involved exclusively in water, RMC Water and Environment develops a full range of water management solutions for local communities and public agencies. RMC Water and Environment frequently assists clients in the wastewater treatment sector, which uses treatment strategies such as disposal by dilution. At its core, disposal by dilution involves depositing wastewater into a sufficiently large body of water, such as a large lake or ocean. Although the practice may sound suspicious at first, it does represent an environmentally friendly disposal method when used in the proper situations. As long as the contaminants in wastewater can be broken down safely by oxygen, the dissolved oxygen in a large body of water is often more than enough to handle the task.
  3. 3. Wastewater Treatment • Because disposal by dilution involves introducing contaminants to natural bodies of water, great care must be taken to prevent harm to ecosystems. Wastewater managers must carefully assess the oxygen concentration of a water source, as well as the nature of the contaminants in a wastewater sample. If a body of water does not have enough oxygen to break down contaminants aerobically, anaerobic breakdown may take place, resulting in objectionable organic matter. If toxic compounds such as heavy metals or pesticides build up in natural water sources, it can significantly disrupt the natural food chains in the ecosystem.
