General Septic Sytem Design

Septic System Design is often the last thing you want to deal with in your project. At Clark Civil Engineering we help you solve any issues that may arise without the need to get your hands dirty. If you are located in West Marin, you likely have a septic system that limits much of what you can do with your property. If you are looking to remodel your house, add an ADU, develop a lot or need to repair your current failing system we can offer advice and designs to make the process smooth.

Septic System Design for Repairing Existing Failed Systems

We have experience with everything from repairing half century old septic systems to installing and programming new high-tech drip dispersal systems. We stay up to date on municipal codes and are in constant contact with Marin Environmental Health in order to answer nearly all the question you may have and quickly repair your system with minimal cost. We have the experience, knowledge and certifications to monitor septic systems and ensure that everything is in proper functioning order as well.

Septic System Design for Remodeling, Building Additions and ADUs.

The vast majority of our septic system design is for an addition, or improvements to existing structures. There are many reasons to remodel your house, add a bedroom or construct an ADU but all of those projects in Marin county require an upgraded septic system per county regulations. With the details of your project we can determine the site feasibility using our broad knowledge of local soils and save you time and money on effective and long lasting project design.

Septic System Design for New Lot Development

Many undeveloped lots are available across Marin County for one single reason, the soil lacks the basic requirements to build a functioning septic system. At Clark Civil Engineering we deal with many elements of residential lot development and septic is often the most critical constraint we work with. We are able to test your soil and verify lot feasibility before you invest money and time into the property. We are able to quickly determine your maximum bedroom count as well as septic system location so it can be incorporated into the architectural design of the house with only a few standard test. We also provide surveying and Grading and Drainage engineering to allow for smooth project coordination from the start to the finish of your project.
