Where We Work: Our Service Area
Risha Enterprises is based in Sunbury, Ohio, and proudly serves a wide range of surrounding communities with septic system installation, excavation, trenching, pole barn construction, site preparation, and more. For more than 35 years, we’ve worked throughout central Ohio, helping homeowners, builders, and property owners improve their land with reliable, experienced service.
We understand the unique challenges of rural and semi-rural construction—from soil conditions and drainage to access and permitting. Our team is local, fully insured, and familiar with the requirements of each county we serve.
Whether you’re building a home, preparing land for a pole barn, or replacing a failed septic system, we’re here to help—with responsive service and workmanship that lasts.
Primary Service Area
Our core service area includes Sunbury, OH and the following nearby communities:
- Galena, OH
- Johnstown, OH
- Centerburg, OH
- Marengo, OH
- Mount Vernon, OH
- Delaware, OH
- Westerville, OH (outside city limits)
We operate throughout these towns and the surrounding rural areas, bringing excavation and septic solutions directly to properties that aren't connected to municipal utilities or require private development support.
Areas Just Outside Our Range
While we serve much of central Ohio, there are some areas we do not currently service, including:
- Columbus city limits
- Highly urbanized areas with restrictive zoning for septic or excavation equipment
- Locations requiring full commercial construction permits or large-scale infrastructure projects
If you're not sure whether your property falls within our coverage area, just contact us. We're happy to review your address and determine availability.
Counties We Serve
Risha Enterprises works across several counties in central Ohio, including:
- Delaware County
- Knox County
- Licking County
- Morrow County
- Franklin County (rural border areas only)
-
If your property is in an unincorporated or agricultural area of these counties, there’s a strong chance we can provide service.

What to Expect When Working with Us
When you contact Risha Enterprises, we’ll start with a free consultation and site visit. During that visit, we assess:
- Your land's layout and access points
- Soil type, grade, and drainage patterns
- Required permits or code considerations
- Equipment accessibility
- Your timeline and goals
From there, we provide a clear written estimate, including scope of work, materials, schedule, and cost.
We’re familiar with the building departments and health inspectors in each county we serve, which helps speed up coordination and inspection approvals. Whether you're in Delaware County or northern Licking County, we know how to work within local processes to keep your project on track.
Local Experience Makes a Difference
Having served this region for over three decades, we understand:
- How to install septic systems that pass inspection the first time
- The right grading solutions for clay-heavy or low-lying soils
- How to build stable foundations in areas with seasonal water issues
- Where access roads are needed for heavy equipment
- How to protect nearby wells, streams, or property lines from disturbance
We apply local knowledge to reduce delays and avoid common pitfalls—saving you time, money, and frustration.
Frequently Asked Questions
How far do you travel from Sunbury?
Most projects fall within a 30- to 40-mile radius, including towns like Johnstown, Mount Vernon, and Delaware. If your site is slightly outside this range, we may still be able to help—especially for larger projects.
Do you serve all of Delaware and Knox counties?
Yes, we serve most rural and suburban parts of these counties. We avoid dense urban areas where excavation or septic system installation may be limited by zoning or utility access.
Why don’t you service Columbus?
We specialize in rural and suburban properties where septic systems, private land development, and site access are required. Columbus properties are typically served by city utilities and have limited demand for our core services.
Can I get a quote even if I’m unsure I’m in your area?
Absolutely. Contact us with your address and project type. We’ll confirm availability and provide a consultation at no cost.
Will my location affect pricing?
Travel time is factored into the overall quote, but we do not charge separate travel fees for jobs within our normal coverage area. More remote locations may require scheduling flexibility.
