NataliaReady · ask anything about wastewater
Welcome.
Tell me about your wastewater problem. You can type it or use the microphone. I can help you explore technology options, compliance questions and the information needed for a preliminary engineering proposal.

PROJECT INTELLIGENCE
Natalia is building your engineering brief.
The conversation is being progressively qualified.
ENGINEERING INTELLIGENCE
More than a chatbot.
Natalia is designed around the way environmental engineering decisions are actually made.
Project qualification
Identify missing engineering data and progressively build a structured project brief instead of guessing.
Flow · COD · BOD · TSS · pH · location
Compliance guidance
Explore NEQS and project-specific discharge or reuse requirements with clear caveats and source-aware reasoning.
Discharge · reuse · approvals · risk
Human engineering handoff
When an enquiry becomes commercially meaningful, the conversation can move toward a formal Critical GREEN proposal.

FROM QUESTION TO PROJECT
A conversation that can become an engineering brief.
01Ask
Type or speak naturally.
02Analyse
AI identifies intent and data gaps.
03Retrieve
CG knowledge is brought into context.
04Qualify
Serious project enquiries become structured briefs.
WHEN AI ISN'T ENOUGH
Bring a human engineer into the conversation.
AI can explore the problem. Critical GREEN engineers verify the engineering, site conditions and final proposal.
