The problem, in plain words

Water and sewage run downhill. When a house, a shop or a low part of a yard sits lower than where the water needs to go, gravity is not enough. A wet well is the answer: an underground tank that collects the water, and a pump that lifts it to the sewer, the street or a drain line.

A wet well needs the right size tank, a pump that keeps up, controls, and an alarm so you know when something goes wrong. We install and repair them in Philomath, Corvallis, Albany, Lebanon, Monroe and around.

Signs you have it

  • The high-water alarm is going off
  • Drains slow down or back up in the low part of the property
  • The pump runs nonstop, or not at all
  • A smell around the tank lid
  • Water pooling around the lid after rain

What we do

  1. Check the system

    We check the tank, the pump, the floats or controls, and the alarm.

  2. Repair or replace

    Worn pumps and bad floats get replaced. A cracked or too-small tank may need to be replaced.

  3. Dig and set

    For a new wet well we dig, set the tank level, and connect the lines in and out.

  4. Test it

    We run water through it and check the alarm before we leave.

Questions about wet wells

What is the difference between a wet well and a septic tank?

A septic tank treats sewage and lets the liquid drain to a drainfield. A wet well only collects and pumps. Some properties have both.

My wet well alarm is going off. What do I do?

Use as little water as you can and call us. The alarm means the level is high and the pump may not be keeping up.

Do wet wells need checkups?

Yes. Pumps and floats wear out, and a checkup keeps a small problem from becoming a backup. TODOhow often Colin recommends a check

Do I need a permit?

New wet wells and sewage pump systems usually need a permit. We will tell you what yours needs.
