Hawaii Water Systems by Stress Band

These pages group Hawaii community drinking-water systems into stable, watch, fragile, high stress, and critical categories. Each hub links directly to profile pages and keeps category-level context concise.

Stable

Systems in the Stable band (MISI 0–20) show low structural stress across operational, financial, and governance dimensions. These systems generally have manageable compliance postures, adequate capital investment patterns, and sustainable revenue structures.

Watch

Systems in the Watch band (MISI 21–40) exhibit emerging stress indicators that warrant monitoring. One or more risk families may show moderate pressure — often early signs of capital deferral, revenue concentration, or demographic shifts affecting the customer base.

Fragile

Systems in the Fragile band (MISI 41–60) face meaningful structural challenges across multiple risk families. Typical patterns include concurrent operational stress and capital pressure, or revenue fragility paired with governance risk.

High Stress

Systems in the High Stress band (MISI 61–80) exhibit significant structural risk. Multiple score families are elevated simultaneously — often combining compliance burdens, deferred infrastructure investment, affordability constraints, and revenue fragility.

Critical

Systems in the Critical band (MISI 81–100) face severe, multi-dimensional structural stress. These systems typically show the highest concentration of active compliance actions, capital gaps, revenue instability, and governance challenges.
