Site Drainage Plumbing in the South Bay
A civil or landscape plan with plumbing drains? Send the sheets for a site drainage estimate.
Schulze Plumbing Inc. provides Site Drainage Plumbing in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

Site drainage plumbing is the whole picture: roof, area, and catch basins tied to piping and a legal outlet. It is how a small lot in Hermosa stops pushing water into a garage.
Civil engineers may own the design. We install the plumbing portions. Grading is not something we invent on this page.
Common symptoms
- A plan set with storm notes
- Chronic site flooding without a single obvious clog
- A remodel that changed paving and created a new low point
What this service involves
- Reading the drainage plan
- Installing the plumbing parts of the system
- Coordinating discharge and other trades

FAQ
- Do you design the civil drainage?
- We install. If you have no plan, we can propose plumbing drains from a walkthrough, but large grading issues need a designer.
- Neighbor disputes?
- We pipe to legal outlets. We do not referee property lines on the internet.
- Retention or cisterns?
- If they are in the plumbing scope, mention them. Some are civil/landscape tanks.
