Engineering
WYN Services Group, we provide engineering solutions designed specifically for decentralized wastewater systems. Our approach combines technical expertise with hands-on operational understanding, giving you designs that perform reliably and remain compliant, year after year.
Site Evaluation & Feasibility
Every successful wastewater project starts with understanding the site. We help you determine the right approach so you can commit to a direction with confidence.

- Soil and site suitability assessments
- Flow projections and system sizing
- Technology comparison (Membrane Bioreactor, Sequencing Batch Reactor, Moving Bed Bioreactor, drip dispersal, recirculating systems)
- Conceptual layouts and cost projections
System Design & Engineering
We design systems built to perform, efficient to run, straightforward to maintain, and compliant with the codes that govern them.

- Decentralized treatment system design
- Pump station and collection system design
- Dispersal field layouts
- Electrical and controls coordination
- Construction drawings and permit-ready plans
Permitting & Regulatory Support
Permitting is where good projects often stall, so we manage the regulatory process from start to finish and stay with you through construction and startup.

- State environmental regulatory permit applications (TDEC, ADEM, etc.)
- Local approvals and coordination
- Responses to technical comments
- Support through construction, startup and beyond
Diagnostics & Troubleshooting
When a wastewater system isn't performing the way it should, we find out why and address the root cause, not just the symptoms.

- System performance evaluation
- Flow and loading studies
- Equipment and process diagnostics
- Engineering-based corrective recommendations
Upgrades, Expansions & Modernization
Properties change, and the systems serving them need to keep up. We help existing systems grow and evolve without starting over from scratch.

- Capacity expansions
- Treatment upgrades and retrofits
- Efficiency improvements
- Control panel and automation modernization
Wastewater Construction Support
A design is only as good as the system built from it, so we stay involved through construction to make sure yours is built right.

- Submittal reviews
- Site inspections
- Startup and commissioning support
- Final system verification
