Dear Michelle:
The property mentioned above is to be served by the City of Yelm sewer system.
The STEP (Septic Tank Effluent Pumping) System is a part of our sewage system designed for particular areas. The STEP System has distinct characteristics, as follows: smaller pipes
made from PVC (polyvinyl chloride) can be used; the pipe does not have to be laid as deeply in the ground as the conventional gravity system; intrusion by sand and ground water is virtually
eliminated; manholes are not required; and the system allows freedom in site layout of new developments.
The system is owned and operated by the City of Yelm. Electrical service is provided by separate utility service or from the house panel. The on-lot equipment consists of the pre-treatment
tank, pump, control panel and miscellaneous appurtenances. Wastewater from the house travels through a pipe into the STEP tank. In the tank, the wastewater is treated anaerobically.
When the liquid level in the tank reaches the proper height (approximately 75 gallons), the control system turns on the pump, which then runs about 7-10 minutes, pumping a set volume
of liquid out of the tank through the service line to the pressure main, and on to the Wastewater Treatment Plant.
After installation is approved by the City of Yelm Sewer Department, the tank, lines and appurtenances, including the main, is deeded to the City for ownership and maintenance.
If you have any questions, please feel free to give me a call at (360) 458-8496.
Sincerely,
Tami Merriman
