FAQ

Most residential septic tanks should be pumped every 3 to 5 years, depending on household size, water usage, and tank capacity. Regular septic tank pumping helps prevent backups, protects your drain field, and extends the life of your septic system.

In many cases, we can provide next-day or even same-day delivery depending on availability and your location. Whether you need a single portable restroom for a construction site or multiple luxury restroom trailers for a large event, our team works to deliver on time and keep your project or event running smoothly.

The number of units depends on your workforce or expected attendance, the length of your project or event, and whether food or beverages will be served. Our experienced team will recommend the appropriate number of portable restrooms, handwashing stations, ADA units, or restroom trailers to ensure your guests or crew remain comfortable.

We offer flexible service schedules based on your needs, including weekly, bi-weekly, or custom service plans. Every service includes pumping, cleaning, sanitizing, and restocking supplies to ensure your portable restrooms remain clean, sanitary, and ready for use throughout your rental period.

Barnhill’s Services is your complete sanitation and site services partner. In addition to portable restroom rentals, we provide luxury restroom trailers, ADA-compliant units, handwashing stations, temporary fencing, septic tank pumping, and commercial grease trap cleaning for construction projects, weddings, festivals, businesses, municipalities, and special events throughout South Carolina.
