About OSO Liquid Waste

OSO Liquid Waste is based in Floresville, Texas, the seat of Wilson County, located about 30 miles southeast of San Antonio. The company handles both septic services and portable toilet rentals, making them a practical choice for construction sites, outdoor events, and rural properties throughout the region. Floresville sits in an area experiencing steady residential growth as San Antonio's suburbs expand outward, which means demand for septic installation and maintenance is rising. Their dual service offering gives them flexibility to serve both individual homeowners and contractors managing larger projects.

Services & Process

OSO Liquid Waste covers two distinct but related areas of liquid waste management. On the septic side, services typically include tank pumping, routine maintenance, and system inspections for homes and commercial properties in Wilson County. Their portable toilet division serves construction projects, outdoor events, weddings, and any situation where temporary restroom facilities are needed. Both sides of the business rely on vacuum truck equipment, meaning the same core infrastructure supports both service lines. Customers managing a rural property development or hosting a large outdoor event in the Floresville area can address both needs through one company.

Service Area

OSO Liquid Waste operates out of Floresville and serves Wilson County along with surrounding South Texas communities. Their reach likely extends toward the San Antonio metro area to the northwest and into neighboring Karnes, Atascosa, and DeWitt counties, given the rural spread of the region and the demand for mobile liquid waste services.

Frequently Asked Questions

Can OSO Liquid Waste handle both a septic pump-out and portable toilet rental for my construction project?
That's one of the advantages of their dual-service setup. They can schedule the septic service for the existing system on your property while also delivering portable units for your crew, coordinating both through a single call to their Floresville office.
How many portable toilets do I need for an outdoor event near Floresville?
A general rule is one unit per 50 to 75 guests for a 4-hour event, with more needed if alcohol is being served or if the event runs longer. Your provider can help you estimate based on guest count and event duration.
Does Wilson County require permits for septic system repairs or installations?
Yes, Texas requires that septic system installations and significant repairs be permitted through the local authorized agent, which for Wilson County is typically the county's environmental health office. A licensed installer like OSO Liquid Waste should handle the permitting process as part of the project.
How is liquid waste from portable toilets and septic tanks disposed of legally in Texas?
In Texas, liquid waste haulers must be licensed by the Texas Commission on Environmental Quality, and waste must be disposed of at approved facilities such as wastewater treatment plants. Reputable providers like OSO Liquid Waste transport waste only to permitted disposal sites.
What's the right pump-out schedule for a septic system on a Floresville area property?
Every 3 to 5 years is the standard recommendation for a typical household, but properties with more occupants or smaller tanks may need service more frequently. Homes in Wilson County that see seasonal or part-time use might be able to stretch the interval slightly longer.
Can I get portable toilet service for a long-term construction project in rural South Texas?
Yes, most providers offer ongoing service agreements for extended construction projects, which include regular cleaning and waste removal on a weekly or bi-weekly schedule. For remote sites in Wilson or surrounding counties, confirm the service area and any additional travel fees before committing.
