What You Need To Know About Your STEF or STEP System

If your home or business has a septic tank on the property, it is tied into the City of Camas sewer main as a part of the municipal wastewater treatment system. Solids collect in the septic tanks, and are pumped every 6-10 years by the City. The wastewater is filtered and sent out to the wastewater system. Residents can protect the wastewater treatment system, home plumbing systems, and the environment by not flushing items that do not degrade readily. Even products that claim to be "flushable", such as wipes, or feminine hygiene products, are not suitable for septic tanks or wastewater systems because they do not break down. Please flush wisely to protect pipes and the environment.

Septic Tank Effluent Pumping Systems (STEP)
The “STEP system” means a sanitary sewage system which utilizes a high head pump, alarms, and a control panel to pump grey water from a collection tank into pressurized mainlines.                                                        

Septic Tank Effluent Filter System (STEF)  
The “STEF system” means a sanitary sewage system which operates by siphonage instead of pumping and which contains a high-level alarm and electrical panel.

Identifying the System your Property Contains
The Homeowner can identify the system installed at their residence by looking at the alarm panel located on their residence.This panel will be approximately 12”x 12” if a STEP system, and 6” x 6” if a STEF system. The alarm is located on this panel and can  be depressed to turn off the alarm. 

Ownership of the STEP/STEF System
After inspection and acceptance of an installed STEP/STEF system on residential property, the City shall be the owner of all components of the STEP/STEF system with the exception of the sewer line from the structure to the tank, which shall be owned by the property owner. The City will be responsible for maintaining the components of the STEP/STEF system owned by the City, and in addition will be responsible for pumping the STEP/STEF tank and disposing of waste material when required.  The owner will be responsible for maintaining the sewer line connecting the tank to the structure on the homeowner’s property.  The owner will also be responsible for paying for all electrical costs associated with the operation of the STEP/STEF system. (City of Camas Ordinance 13.62.060)

The City and its employees need to have access to the homeowner’s property for the purpose of maintaining and inspecting the STEP/STEF system.

Damage to the STEP/STEF System 
The cost of repairing any damage to a STEP/STEF system which has resulted from the negligence, gross negligence, or intentional acts of the owner shall be the responsibility of the owner.  This responsibility includes  any clogging which may result due to improper use of the system by the homeowner. (City of Camas Ordinance 13.62.070)

Landscaping over STEP/STEF Tanks
The green riser lids cannot be covered by landscaping. The riser lid to the access chamber must be accessible at all times to insure proper and timely emergency and/or maintenance response to the system. Accessible means visible to the naked eye, and with a minimum of one-inch separation from the top of the riser lid to the adjacent ground surface. (City of Camas Ordinance 13.62.080)
