How We Work

Greenworks of Washington provides septic pumping services, repair, and inspection. This includes standard tank inspection (NOT county-mandated inspection), disposal of removed waste and reasonable dig time (approximately 30 minutes) to accomplish this work.

Septic tank pumping and repair is a highly variable service, with wide ranges in pricing and quality from various companies. Greenworks differentiates itself from the competition by providing the highest level of customer service possible through education and excellent service. Many customers have chosen to learn about the systems that they use everyday and have a willingness to change their behavior to the greater common good.

In 2005, the Washington State Department of Ecology and Department of Health revised the Washington Administrative Code #246-272A. By doing so, the local jurisdictions that monitor and report septic system failures and behavior were put under intense scrutiny. Counties are required to have all septic systems inspected and functional at the time of property transfer, also known as Operations and Maintenance Inspections (OSM). Some counties have put these OSM Inspections as the top priority of their wastewater departments. Other counties are still in the process of developing their local programs.
