Drain cleaning in San Marco

Local conditions

Why drains fail in San Marco

San Marco has two completely different drain conversations happening at once. Residentially it is 1920s construction with the cast iron and clay you would expect, on ground that sits low enough that storm drainage and river level genuinely matter. Some of the streets closest to the river have a long documented history of standing water in heavy rain, and exterior drainage there is not an afterthought.

Commercially, San Marco Square and the surrounding blocks pack a lot of kitchens into a small area, many of them in buildings whose waste lines are as old as the residential ones around them. A 1920s building running a modern high-volume kitchen is a grease line on a short fuse, which is why the restaurants here tend to end up on a jetting schedule rather than an emergency call list.
