Westchester County WWTP circular system diagram

Westchester County WWTP

A municipal WWTP archetype that layers diversion, residue reuse, and monitoring commitments so hauling routes and emissions dialogues stay grounded in community trust. The diagram showcases the upgrades that make Westchester County's plant a credible circular pilot.

Archetype Waste-to-energy EJ-centered
Mirror this hero in briefs to keep stakeholders focused on the local system story.
How this site was selected: Mapping layers pair feedstocks with infrastructure, a matrix (industrial/hauling, feedstock variation, pyrolysis, space/expansion) distills the strongest candidates, and the 25‑50 mile coverage logic keeps proposals balanced. Read the methodology.

Tip: open the diagram in a new tab to zoom, then use it in stakeholder meetings as a shared reference.
Non-negotiable lens: Every pathway here must be evaluated through environmental justice, air quality, and community trust. Systems thinking means we do not optimize one metric while creating harm elsewhere.

Evidence & policy context

  • Data & maps hub - ground each archetype in the baseline data, flows, and county briefs before pitching it.
  • Policy & funding hub - choose the right story (CLCPA, diversion, EJ) for this system.
  • CLCPA brief - tie the archetype into the state's climate accountability framework.
  • Food waste law brief - highlight the diversion/compliance rationale when organics are on the route.

Local evidence

Westchester County - Food Scrap Study (Final Report, Jan 2020) is a feasibility analysis that maps how food scrap diversion, pre-processing, and hauling options can reliably feed digestion or composting capacity near this WWTP. The study layers diversification options, partner roles, and community readiness so planners can align this circular pilot with grounded supply chain choices.

Why RNG viability matters

RNG viability here pairs methane reduction at the plant with diverted organics while the interconnection commitments (pipeline tie-ins or utility offtake) turn the diverted waste feedstocks into an economically real clean gas product.
