Excavation & Septic Services You Can Rely On in Marion County, Iowa and Beyond

When you are planning a project that involves your land, your foundation, or your water systems, you need more than just equipment. You need a contractor who understands how everything works together.

At DC Underground LLC, led by owner Caleb Attema, we provide excavation and septic services for homeowners, builders, and landowners throughout Marion County and surrounding areas in Iowa. From site preparation and grading to septic installations and drainage systems, every project is handled with precision, care, and a focus on long-term results.

We are not here to rush through jobs or cut corners. We are here to do the work right so your project starts strong and stays that way.

Local Excavation Services Built for Iowa Land

Excavation is the foundation of almost every outdoor project. If it is not done right, everything built on top of it is at risk. Our excavation services are designed to prepare your land properly the first time. Whether you are building a home, installing utilities, or improving your property, we focus on creating a stable, functional base that supports your goals.

We handle:

• Residential excavation
• Commercial excavation
• Site preparation
• Land clearing and mulching
• Grading and leveling
• Demolition and debris removal
• Pond and drainage excavation
• Utilities trenching

Every property in Iowa is different. Soil conditions, elevation, and water flow all play a role in how excavation should be done. That is why we take the time to evaluate your site before we start moving dirt. Our goal is simple. Create a surface that drains properly, supports structures, and sets your project up for success.

Septic System Services That Work Long-Term

Septic systems are one of the most important systems on your property, yet they are often overlooked until there is a problem. We provide septic solutions that are designed to last, not just pass inspection.

Our septic services include:
• Septic system installation
• Septic system pumping
• System upgrades

From traditional systems to more advanced setups, we handle every part of the process. That includes planning, excavation, installation, and ensuring everything meets local regulations. Many septic issues start with poor installation or improper drainage. By combining excavation knowledge with septic expertise, we are able to build systems that function properly and avoid costly problems down the road.

Drainage and Water Management Solutions

Water is one of the biggest threats to your property if it is not managed correctly.


Standing water, erosion, and poor runoff can damage foundations, destroy landscaping, and make land unusable. That is why drainage is not an afterthought in our work. It is a priority.

We design and install:


• Drainage systems
• French drains
• Water diversion solutions
• Retaining walls for runoff control
• Waterproofing support for foundations

Every drainage solution starts with understanding how water moves across your property. Once we identify the problem areas, we create a plan that moves water away from structures and prevents future damage.

Land Management and Property Improvement

Your land should work for you, not against you.
We offer land management services that help improve usability, appearance, and long-term value.

These services include:
• Brush clearing
• Pasture maintenance
• Land clearing for new construction
• Soil improvement through mulching
• General property upkeep

Whether you are preparing land for building, agriculture, or recreation, we help you get the most out of your property.

Utility and Waterline Installation Services

Reliable utilities are critical for any property. Whether you are building new or upgrading existing systems, proper installation is key.

We provide:

• Waterline installation

• Utility trenching

• Sewer line support and repairs

• Foundation-related trenching

Precision matters in this type of work. Incorrect depth or placement can lead to major issues later. Our trenching and installation process is carefully planned to ensure everything is installed correctly and safely.
