sewage disposal systems in Howard County are performed properly. Our program reviews all proposed designs for on-site sewage disposal systems to ensure they follow State and Local regulations. Environmental Health Specialists conduct inspections of wells and onsite sewage disposal systems and test water from private drinking wells to protect residents from diseases associated with germs found in wastewater.

Well and Septic Public Files Search

The Bureau of Environmental Health has completed a multi-year project converting paper files to electronic records that are now available on our website.The Public Files Search link contains Health Department Well and Septic Program residential property files from approximately 1985 to the present. Some properties constructed before 1985 may contain a file in this system if activity such as a building permit or sewage disposal system repair occurred after 1985. 

Search Public Records by clicking here.

Non-residential properties, undeveloped lots, subdivision master files, properties in which development is ongoing, and properties in which no activity has occurred since before approximately 1985 are not in this system. If you do not find the property file in this system, please submit a  Public Information Act Request.

Code Revision
A revision to the Code of Maryland Regulations 26.04.02.07 will become effective on November 24, 2016. It eliminates the requirement for BAT (Best Available Technology) units on all new construction and upgrades in the non-critical areas of the State, including Howard County. Some properties may still require BAT units based on site specific conditions. A guidance document explaining how this change affects properties in Howard County is provided in the COMAR BAT Revision Memo. A list of requirements for sewage system design plans not utilizing BAT is provided in the OSDS Design Plan Requirements.

Wet Season Testing 2017
The Health Department ended testing in wet season soil units on April 28, 2017 due to water table levels having dropped below their seasonal high. We will continue to monitor water table levels for any changes.  At this time, testing in wet season soil units other than for repairs to failing systems, will not be scheduled until the next designated wet season. 

Well Mapping Project

In the summer of 2006 a project was initiated to inventory and locate all of the private drinking water wells in Howard County. For more information about this project, click here
