Services
Land Surveying
Our licensed surveyors conduct precise boundary evaluations using advanced Carlson Civil software. We provide detailed topographic mapping and property line determinations for residential and commercial developments. Our team ensures compliance with Vermont state regulations while maintaining clear communication throughout the survey process.
Septic Design
We design customized septic systems based on site-specific conditions including soil composition and groundwater levels. Our process includes test pit excavations, soil profile analysis, and comprehensive system planning. We ensure all designs meet local health department requirements while optimizing system longevity and efficiency.
Soil Testing
Our licensed designers perform detailed soil excavations to determine optimal wastewater disposal areas. We analyze soil horizons for texture, density, and seasonal water table levels. This critical data informs septic system placement and ensures long-term functionality through accurate percolation testing.
Permit Assistance
We guide clients through state and local permitting requirements for wastewater systems and land subdivisions. Our team prepares necessary documentation, coordinates with regulatory agencies, and ensures compliance with environmental standards. We streamline the approval process through established relationships with local authorities.
Filtrate Disposal Systems
We implement advanced filtrate effluent disposal systems that enhance wastewater treatment. These systems reduce isolation distances to limiting factors like bedrock and groundwater, making previously unusable sites viable. Our designs incorporate secondary treatment processes to improve system performance and environmental safety.
