The Tahoe-Truckee Sanitation Agency, or TTSA, is committed to a policy of energy and natural resource conservation. Our goal is to discharge the treated wastewater in the Truckee River Corridor in such a manner as to retain the integrity of ground and surface waters, while ensuring the quantity of water downstream is not diminished.

The Agency is committed to policy of conservation and recycle. A few examples are cited:

  • The biological removal process substantially reduces chemical demands, energy, and landfill stresses.
  • Anaerobic sludge digestion results in methane gas. This fuels boilers to provide building and process heat.
  • Combustion offgases, principally carbon dioxide, is an integral component in pH control.

The TTSA is made up of five entities:

  • Tahoe City PUD (530) 583-3796
  • North Tahoe PUD (530) 546-4212
  • Squaw Valley Public Service District (530) 583-4692
  • Alpine Springs County Water (530) 583-2342
  • Truckee Sanitary District (530) 587-3804

Treated effluent is piped out through a soil aquifer treatment system through a series of laterals where physical, chemical and microbial activity improve water quality further. This large discharge field contains monitoring wells, which are monitored regularly. Effluent is retained within the system for a minimum of 50 days, then the aquifer emerges to the Truckee River or Martis Creek through seepage.
