Septic Tank Cleaning

septic tank cleaning

SES Company's licensed operators determine when your septic tank or other treatment tanks need to be cleaned as a part of all of our standard service plans.

Most local Health Departments recommend that septic tank systems be cleaned every 3 - 5 years depending on the use and age of the septic system. Those who live in the Chesapeake Bay Preservation area are required to have their septic tank systems pumped or inspected every five years.
