Well & Septic Program

The Well and Septic Program ensures that the installation and repair of all drinking water wells and on-site 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.

Wet Season Testing 2024

The Health Department opened wet season testing on January 25, 2024 based on current observed water table levels.

We will be scheduling testing for projects already submitted. New applicants must submit a perc test application and test plan to the Health Department by February 9, 2024 in order to be assured of testing during wet season.

We will continue to monitor water table levels and schedule testing beyond that date for as long as conditions allow. Updates to the wet season schedule will be posted here. Contact the Well and Septic Program at 410-313-1771 with questions.

I want to find Health Department records on a septic system and/or a well

Content

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.*

(*Note: When searching for property records in the database, enter only the numbers of the street address and choose the requested property from results given.)

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.
