Smoke Testing Feb 2nd and 3rd!

The City of Ilwaco Wastewater Department will be conducting SMOKE TESTING of the sanitary sewer system on Tuesday February 2nd and Wednesday February 3rd, 2021.

The areas being tested will be North of Spruce Street from First Avenue to Elizabeth Avenue.

Should smoke enter your home or business, please contact Ilwaco City Hall at 360-642-3145.

This study will involve the opening and entering of manholes in the streets and public utility easements. An important task of the testing will be to locate breaks and defects in the sewer system. The smoke will also reveal sources of where storm and other surface water enter the sewer system.

Prior to the testing, homeowners are requested to pour water down all drains of plumbing fixtures that are not regularly used in order to fill the P-traps, which will help prevent smoke from entering the house, but if traces of this smoke or its odor do enter your house or building, it is an indication that gases and odors from the sewer may also enter. These can be both unpleasant and dangerous, as well as a health risk to the occupants.

A special non-toxic smoke will be used in these tests. The smoke is manufactured for this purpose, leaves no residuals or stains, and has no effect on plant or animal life. The smoke has a distinctive, but not unpleasant, odor. Visibility and odor last only a few minutes, where there is adequate ventilation.

Because the plumbing appliances in your house or building are connected to the sanitary sewer system, some smoke may enter your home or place of business if the:

  • Vents connected to your building’s sewer pipes are inadequate, defective, or improperly installed,
  • Traps under sinks, tubs, basins, showers and other drains are dry, defective, improperly installed, or missing,
  • Pipes, connections and seals of the wastewater drain system in and under your buildings are damaged, defective, have plugs missing, or are improperly installed.
