The Story
Baltimore's Department of Public Works has expanded its Sewage Onsite Support (SOS) Cleanup Program to cover certain dry-weather basement backups, according to Conduit Street, the Maryland Association of Counties blog. The program previously covered only wet-weather backups tied to heavy or sustained rain. Under the expanded pilot, residents may qualify when a dry-weather backup is caused by a blockage on the City-owned side of a sewer lateral.
Eligible homeowners and renters receive professional cleaning and disinfection at no cost through third-party contractors the City connects them with, Conduit Street reports. DPW developed the expansion with the Maryland Department of the Environment and says pilot data will help it understand where backups occur and what causes them.
A separate Expedited Reimbursement Program continues to repay eligible households up to $5,000 for qualifying cleanup and disinfection costs they have already paid, according to Conduit Street.

The infraTerra Take
Florida utilities should decide now, in writing, where their side of the lateral ends and what they owe a resident when a backup starts on the public side. Baltimore just drew that line by tying cleanup help to where the blockage sits, not to the weather. That is the right test, and it only works when the utility can prove where the blockage was.
That is the real lesson here. Many systems lack a clean record of where each lateral connects, which segment is public and what condition it is in. When a backup claim lands, the answer often turns on a cleanout location or an ordinance nobody has read in years. Baltimore plans to use its pilot data to learn where backups occur and why. Florida utilities can do the same with the backup calls they already log, and that record also points crews toward the defective lateral connections that let groundwater and rain into the collection system.
For contractors, clearer ownership lines mean cleaner scopes. Lateral inspection, cleaning and lining work is easier to price and approve when the utility has already defined which segment it is paying for. For property owners, know where your responsibility starts, and ask your utility before paying out of pocket for a backup that began on the public side. Our lateral ownership map is a starting point for seeing how Florida jurisdictions draw that line.
What to Watch
- Whether Baltimore DPW publishes pilot findings on where and why dry-weather backups occur
- Whether the dry-weather coverage moves from pilot to a permanent program
- Florida ordinance updates that define public and private lateral segments for backup claims
