Beginning with a septic tank system installation, Goodman Sanitation in Portland, OR is the reliable source for all of your wastewater treatment needs.We are here to take care of your septic system from start to finish.We will be glad to consult with you about your septic system needs.Our estimates are always free.
There are many factors involved in the installation of a septic tank system.We are a professional company with the knowledge and experience to expertly determine the proper location and optimum size for your new septic system.We will speak with you about water usage, how many people will be using the system, the use of washing machines and garbage disposals, and water conservation techniques to ensure your septic tank functions properly.
We look at the location of the plumbing in your home or business and view the slope of the land and your lot configuration.The septic tank will be placed in an area with more than adequate drainage that can be accessible for pumping when routine maintenance is needed.Hoses on pumper trucks typically reach up to 50 feet.
It is most desirable to have a gravity flow all throughout your wastewater treatment system.This avoids the need for mechanical assists like valves and pumps.But, in situations where the dwelling is not high enough for gravity flow to the tank, grinder pumps or sewage ejector pumps can be installed to lift the wastewater to an elevation suitable to drain into the septic tank.
Before excavation, all buried gas, electric, and other utility lines will be located.For new construction, we also take into consideration any possible future expansion and locations of sidewalks, driveways, garages, patios, and storage buildings.We will also consult with you about the proper landscaping for a septic system site to make sure plants, trees, and roots do not interfere with the drainfield.
With the proper maintenance scheduling, your septic tank system will provide you with years of service and Goodman Sanitation will make sure everything flows smoothly.
