# Outside Drain Clogged: Yard Drain, Storm Drain or Sewer Backup?
Identify the kind of outside drain before requesting help. Rainwater drainage and a sanitary sewer need different reporting and service scopes.

## The short answer
A yard inlet taking rainwater is different from a sewer cleanout connected to toilets and household plumbing. Do not open an unfamiliar cover or enter a drain structure to investigate. Tell the provider where the drain is, what normally flows into it and what you have already seen.

## Rainwater pooling near a yard inlet
Leaves, sediment, a restricted outlet, grading and a damaged drain can each contribute to poor drainage. Surface pooling does not prove a household sewer clog. Describe whether the problem appears only during rain and whether street drainage is involved. Outdoor storm-drain clearing is not included in a household drain appointment unless the provider confirms it.

## Wastewater outside or a public manhole overflowing
Keep clear of sewage and do not remove public covers. Use the relevant city reporting route when a public sewer may be involved. Tell the utility whether neighboring properties are affected and whether the flow appears at a public structure. Private-line clearing and wastewater cleanup remain separate service requests.

## How to reduce repeat surface blockages
Where safe, keep loose leaves and litter away from surface inlets without reaching into them. Do not sweep waste into a storm drain. Recurring pooling warrants assessment of the drainage route and outlet rather than repeatedly treating it as an indoor sink clog.
