Removal of sediment, leaves, trash and debris from catch basins, storm drains, grates and connected structures to keep drainage moving.
San Antonio gets rain in bursts, hard ones, the kind that drop an inch in twenty minutes and then quit, and that pattern is what turns a catch basin into a problem overnight. Catch basin and storm drain cleaning in San Antonio is a call we get right after a storm like that, when a parking lot is holding water it should not be holding and a board member or property manager wants to know why.
The why usually comes down to the ground. Caliche and limestone shelves under much of Bexar County do not let water soak in, so every storm pushes sediment, leaves and construction grit straight toward the nearest inlet. On newer Stone Oak sites we find forebays silting in fast because slopes have not fully stabilized yet. On older in-town lots around Alamo Heights, root intrusion from mature trees and grates that have not been touched in years are the more common finds. Either way, the symptom is the same: slow drawdown, standing water, or an outlet that has gone quiet.
Working with Corral Bros on this scope means one crew that opens every structure, pulls what is clogging it, and checks the connected lines before calling the job done. We coordinate scheduling around tenants, residents or active construction so the site keeps functioning while the work gets done. You get a locally owned, licensed and insured contractor who has seen what Bexar County ground does to a drainage system and knows what normal looks like versus what needs attention.
We're a local, family-built company that treats your San Antonio property like our own, tidy crews, clear pricing, and catch basin & storm drain cleaning that holds up to Bexar County conditions. Available as a one-time project or part of an ongoing plan.
We walk the site with whoever manages the property, open the grates and lids, and look at sump depth and outlet condition before we quote anything. Most estimates in San Antonio are scheduled within 48 hours of your call. You get a straightforward number based on what we actually find, not a guess from the street.
Most commercial sites and HOA-maintained systems here need a cleanout once or twice a year, more often if the property sits downhill from bare slopes or has mature live oaks dropping leaves into inlets. Properties on caliche or shallow limestone tend to silt up faster because water cannot soak in and just carries sediment straight to the basin. A full system after heavy rain or a visibly slow-draining lot is the usual trigger for a call.
We schedule around the property's traffic patterns and coordinate with management on which lots, drive aisles or grates need to stay clear on the day of work. On occupied retail centers and apartment communities we section off work areas rather than closing whole lots, and we keep equipment staged out of the way of tenant access.
Caliche and limestone shelves do not absorb water well, so runoff moves fast and carries grit, leaves and construction debris straight into catch basins and storm drains. On newer Stone Oak builds we often find sediment still washing off exposed slopes, and on older Alamo Heights lots root intrusion and aging grates are more common. Either way, debris settles at the sump and slows the system down until it is pulled out.
Price depends on how many structures are on site, how deep the sediment load is in each sump, and whether connected lines need checking in addition to the basins themselves. A property with silted forebays or buried grates takes longer than one with light leaf debris. Access, whether we are working around active tenants or a closed site, also factors into the estimate.
