Defined phases. Clear decisions.
The right level of engineering at the right time protects the site plan, budget, and regulatory strategy.
WillCo structures work in defined phases so owners can resolve the largest technical and permitting questions before committing to detailed design.
01
Initial Screening
Review the project program, location, site constraints, available plans, anticipated wastewater and water demands, fire-water applicability, and known regulatory issues.
Typical result: preliminary pathway, information request, and proposal for the appropriate next phase.
02
Feasibility & Preliminary Engineering
Develop the design basis, evaluate GIS and site information, estimate flow and loading, compare treatment and disposal alternatives, identify permitting pathways, and establish preliminary cost and schedule implications.
Typical result: feasibility memorandum or Preliminary Engineering Report with a recommended path forward.
03
Regulatory Strategy & Agency Coordination
Confirm the applicable local and state requirements, coordinate pre-application questions where appropriate, and assemble the technical basis for the selected authorization.
Typical result: defined submittal requirements, regulatory strategy, and permit-support scope.
04
Engineering Design
Prepare calculations, equipment criteria, treatment and conveyance design, storage and pumping requirements, disposal layouts, plan sets, specifications, and supporting engineering documentation.
Typical result: permit-ready or construction-ready engineering package appropriate to the project.
05
Permitting & Review Support
Submit or support submittal of the application package, coordinate technical responses, address agency comments within the authorized scope, and maintain a clear record of project decisions.
Typical result: permit support through the agreed review milestone.
06
Implementation & Construction Support
Review selected equipment, answer RFIs, evaluate proposed changes, perform authorized site observations, assist with startup, and document final engineering decisions.
Typical result: construction-phase engineering records and startup support tailored to the system.
Inputs that accelerate the work
Provide the project basis early.
- Current survey and civil site plan
- Development program and phasing
- Occupancy, fixture, process, and operational information
- Existing utility records and permit documents
- Water source, well, and demand information
- Known agency correspondence and design criteria
- Available wastewater sampling or operating records
- CAD files and current project-team contacts
