Enter the Basic Information
- Location Name: Enter your property’s name or address for reference.

Service add-ons and job complexity can increase costs for a septic tank cleaning.
Tank Access Details
Tank access might not seem like a big deal, but just finding the tank can be a big deal if it hasn’t been serviced in years. Dominic Rosales, owner of Juice’s Septic and Grease Pumping in San Saba, Texas, explains the challenges of servicing older septic systems: “A lot of these older systems, here in the state of Texas, the lids are almost always buried. We’re running into all these neglected septic tanks… it becomes a big part of our job to locate and dig them up.” Make sure you get compensated for all this extra work!
- Tank Depth: Standard depth is 4 feet. Deeper tanks require additional equipment and labor.
- Access Type:
- Standard Access: Tank lid is visible and easily accessible
- Buried Lid: Requires digging to access
- No Known Location: Requires location services and additional work.
Riser Installation
A riser is an extension that brings the septic tank lid to ground level, making it easier to access the tank for maintenance and pumping without digging.This is an add-on service you can offer customers.
Roger Wakefield, host of TheTradeTalks, offers this advice: “Why not always carry risers with you and offer them to customers? You could say, ‘Look, we’re digging it up this time, but for $500, we’ll install risers so you’ll never have to dig again.’”
System Conditions
- Drain Field Condition: Affects processing time and potential complications
- Good: No additional charges
- Slow Drainage: +10% to base cost
- Partial Blockage: +15% to base cost
- Severe Issues: +50% to base cost
- Pumping History:

Understanding the formulas
Base labor time formula:
Base Pumping Time (hours) = Tank Size / (Pumping Rate × 60)
Example: 1,000 gallons / (50 gpm × 60) = 0.33 hours
Cost calculation:
Base Cost = Total Labor Hours × Hourly Rate
Final Cost = Base Cost + Additional Charges
+ (Drain Field Multiplier)
+ Riser Installation
+ Access Charges
+ Dumping Fees
Is this a good business model?
Dominic Rosales, owner of Juice’s Septic and Grease Pumping in San Saba, Texas, is proof that even the most overlooked industries can hold real profit potential. With his family-run business, Rosales has transformed septic tank pumping into a lucrative enterprise while building trust with his customers through education and transparency.
“A lot of homeowners… don’t know anything about their septic system,” Rosales explains. “Educating them on what they have, how it works, and what’s causing problems builds trust.” This emphasis on customer understanding has helped Juice’s Septic become a reliable name in their rural Texas community, where neglected and aging systems are a common challenge.
Septic Tank Pumping Offers Recurring Revenue
Septic tank maintenance is a necessity for homeowners in rural areas, making it a recession-resistant business. “The demand is there,” Rosales says. “People aren’t going to stop using the restroom anytime soon.” For entrepreneurs, this demand translates into stable, recurring income, especially with services needed every 2-5 years depending on tank usage and size.
Scaling and Growing the Business
For Rosales, the goal isn’t just to stay in the field forever but to eventually scale the business. “I would like to get to the point to where I kind of slow things down and take more of an executive position,” he says. “Train people up to do the same thing I do.”

This scalability is a key benefit of the septic business model. Entrepreneurs can start small—often with one truck—and gradually expand by hiring additional staff, investing in equipment, and diversifying services. The recurring nature of septic system maintenance ensures a steady customer base, while add-ons like inspections, grease trap cleaning, and advanced tank replacements provide opportunities for upselling.
The septic tank pumping industry may not be glamorous, but it is both profitable and scalable for entrepreneurs willing to invest in tools, customer trust, and long-term growth. With the help of tools like the Septic Cleaning Cost Estimator, newcomers can streamline pricing, educate their customers, and grow a stable business. As Rosales’s story shows, what many overlook as “dirty work” is a clean opportunity for those ready to take the plunge.
