Decentralized utility engineering
Professional engineering for water, wastewater, reuse, fire-water, and related infrastructure serving commercial properties, industrial facilities, and developments beyond organized utilities.
Engagements are structured around the project’s design basis, site constraints, regulatory pathway, and current phase of development.
01 / Flagship service
WillCo Water Independence™
Integrated reclaimed-water and decentralized utility planning that connects wastewater production with project-specific non-potable demand.
- Feasibility studies and Preliminary Engineering Reports
- Water balances, source characterization, and treatment objectives
- Storage, pumping, distribution, and contingency planning
- TCEQ Chapter 210 industrial reclaimed-water strategy and permitting
- Detailed design, implementation, and startup support
02 / Commercial wastewater
Commercial OSSF Design
Engineered on-site sewage facilities for commercial and institutional projects requiring professional analysis, treatment selection, and permit-ready construction documents.
- Wastewater flow and organic-loading analysis
- Treatment and pretreatment system selection
- Flow equalization and dosing design
- Spray, drip, low-pressure, and conventional disposal design as applicable
- Construction-ready plan sets, specifications, and permit documentation
- Coordination with local permitting authorities
03 / Specialty decentralized systems
RV Parks & High-Strength Wastewater
Specialized engineering for facilities with variable occupancy, concentrated loading, food service, dump stations, and other conditions that require more than a standard septic approach.
- RV parks, resorts, and campgrounds
- Restaurants, convenience stores, truck stops, and event venues
- High-occupancy commercial and institutional facilities
- Pretreatment evaluation, phased development, and expansion planning
- Comparison of OSSF, reuse, land application, and discharge pathways
04 / Early project definition
Development Wastewater & Utility Planning
Pre-development analysis used before land acquisition, entitlement, final site planning, or commitment to a treatment technology.
- Feasibility studies and Preliminary Engineering Reports
- Wastewater capacity and loading projections
- Water-supply, storage, and fire-water demand planning
- Disposal, discharge, reuse, and utility-connection alternatives
- System phasing, preliminary layouts, schedules, and opinions of probable cost
- Regulatory pathway identification and agency coordination
05 / State-regulated wastewater
TPDES, TLAP & TCEQ Chapter 217
Engineering support for wastewater facilities requiring state authorization beyond the OSSF program.
- TPDES discharge-permit applications
- Texas Land Application Permit preparation
- Chapter 217 design-basis and facility coordination
- Effluent limitations, organic loading, and hydraulic analysis
- Treatment-process evaluation and engineering reports
- Application exhibits, technical responses, and TCEQ coordination
06 / Conveyance
Lift Stations & Pump Systems
Wastewater conveyance and dosing systems integrated into decentralized or development-scale utility infrastructure.
- Wastewater lift stations and duplex pump systems
- Dosing, flow equalization, and transfer pumping
- Force mains and hydraulic evaluations
- Pump selection, operating points, controls, and alarms
- Coordination with treatment facilities and downstream infrastructure
07 / Water infrastructure
Public & Private Water Supply
Water-supply systems for developments and facilities where municipal service is unavailable or insufficient.
- TCEQ Public Water Supply permitting support
- Groundwater well and source coordination
- Storage-tank and pressure-system sizing
- Booster pump stations and hydropneumatic systems
- Distribution-system planning and utility integration
- Water-demand, reliability, and redundancy evaluation
08 / Rural fire protection
Fire Water Infrastructure
Planning and engineering for projects that must provide reliable fire-water supply beyond a municipal hydrant network.
- Fire-flow and water-supply evaluations
- On-site storage-tank sizing
- Fire-pump and refill-system planning
- Drafting points, hydrants, access, and rural fire-protection concepts
- Coordination with local fire authorities and the civil design team
- Integration with potable, non-potable, and reclaimed-water systems
09 / Related infrastructure support
SWP3 & Construction Stormwater
Stormwater Pollution Prevention Plan support for selected large, phased, or infrastructure-intensive construction projects.
- Construction General Permit applicability and operator coordination
- SWP3 narratives, exhibits, and phased disturbance planning
- Existing drainage-pattern documentation and BMP planning
- NOI preparation support and construction-phase handoff requirements
- Coordination with project civil, environmental, and construction teams

Start with project screening or a Preliminary Engineering Report.
WillCo can compare the available utility, treatment, reuse, disposal, and permitting alternatives before the project commits to full design.
