Drain wells in Fresno county are only permitted after the approval of the County and a variance has been granted. All new drain wells must be rock filled. Brick lined drain wells are no longer permitted in Fresno or Madera Counties. Not all septic systems have drain wells or seepage pits for drainage. Many septic systems utilize leach lines to drain the waste water back into the ground. The soil type and ground water levels are the main determinants in what type of drainage system will be used. The principle is the same regardless of whether the system has leach lines or drain wells. Both provide ample area for water to percolate back into the soil. After a drain well has been drilled, there is a spoils pile of about 25 tons of dirt. Most of the time this dirt is left on the property and can be left in a pile or spread out with our backhoe in an empty area. This dirt can be very useful to property owners who have low spots or other reasons to need extra dirt such as landscaping. The extra dirt can also be hauled away if there is no good place for it on the property. It is a good for a property owner to know the locations of any drain wells on the property to ensure they are not driven over and that no trees are planted too close to them. Knowing the drain well location is also helpful in the event that you ever need to have additional drain wells drilled for more drainage.

Watch the construction of a new drain well (Also known as seepage pit) being brick lined with concrete bricks. These bricks allow water to pass through them through small channels in between the bricks. Water comes out of the septic tank and into the drain well where it then percolates back into the ground.
