Services
Wastewater System Design
We develop customized wastewater systems for residential, commercial, and municipal clients. Our designs integrate site-specific conditions and environmental protections to ensure long-term functionality. Specializing in decentralized solutions that reduce maintenance costs while meeting regulatory standards, we deliver systems optimized for rocky terrains, high groundwater areas, and sensitive watersheds through rigorous technical analysis.
Regulatory Compliance Consulting
Our team guides clients through complex wastewater regulations and permitting processes. We develop standards for alternative collection systems and assist with municipal ordinance creation. By combining technical expertise with policy knowledge, we help clients achieve compliance while balancing environmental protection and operational practicality across Texas and Caribbean jurisdictions.
Site Evaluation & Planning
Comprehensive soil testing and terrain analysis inform our system recommendations. We assess environmental factors to prevent system failures in challenging landscapes. Our evaluations include long-term cost projections and sustainability metrics, ensuring clients receive technically sound solutions that minimize environmental impact while maximizing cost-effectiveness for properties ranging from single-family homes to large resorts.
Effluent Collection Systems
We design efficient small-diameter gravity and pressure effluent lines that reduce infrastructure costs. Our systems separate solids early to minimize maintenance needs, particularly in hilly terrain. By eliminating conventional lift stations, we create reliable collection networks tailored to clustered developments and remote locations, ensuring cost savings across system lifecycles.
Research & Innovation
Pioneering research drives our technical advancements, including patented septage treatment methods. We conduct long-term performance studies on decentralized systems to improve industry practices. Our findings inform both private clients and regulatory bodies, translating academic insights into practical solutions that enhance wastewater management effectiveness in sensitive ecological zones.

Questions
What geographic areas do you serve?
We primarily serve Texas (especially Hill Country) and Eastern Caribbean locations including US Virgin Islands, Anguilla, St. Thomas, and St. John.
How do you handle wastewater design for rocky terrain?
We develop systems that utilize natural site conditions, often designing clustered solutions that minimize rock excavation while ensuring proper treatment and dispersal.
What makes decentralized systems cost-effective?
Eliminating municipal infrastructure reduces capital costs. Our designs minimize maintenance needs through appropriate technology selection and clustered system efficiencies.
Can failing septic systems be upgraded?
Yes, we've successfully replaced failed systems with modern decentralized solutions that produce reusable water while meeting environmental regulations in sensitive areas.
How do you ensure regulatory compliance?
We work directly with municipal authorities to develop standards and review systems throughout their lifecycle to maintain environmental and code compliance.
What's your construction oversight process?
We provide full-phase services including bid review, quality control checks, and final system validation to ensure implementation matches design specifications.
