What is the Munimetric score for Tm Rural Water District, SD?

The current Munimetric Infrastructure Stress Index (MISI) score for Tm Rural Water District, SD is 42.9 out of 100, placing this system in the fragile stress band. MISI is a composite of five structural risk families. Higher values indicate more stress. The score is deterministic, source-backed, and updated as new data becomes available.

Does Tm Rural Water District, SD show signs of drinking-water infrastructure stress?

Munimetric monitors structural stress indicators for Tm Rural Water District, SD across operational conditions, capital needs, revenue stability, rate affordability, and governance quality. The current MISI score and active signals shown in this profile reflect the latest available evidence from EPA, ACS, FEMA NRI, and state financial disclosures.

Does Munimetric rate current tap-water conditions for Tm Rural Water District, SD?

No. Munimetric is not a water testing service and does not make current-condition determinations. This profile tracks structural conditions: compliance posture, financial pressure, infrastructure stress, and governance quality. For current water quality testing results, consult the system's Consumer Confidence Report or contact the local water utility.

Has Tm Rural Water District, SD had a boil water advisory?

Munimetric does not track real-time boil water advisories. For current advisory status, contact your local water utility or state drinking water program. This profile tracks structural risk indicators and compliance history that provide long-term context around system reliability.

Are lead pipes or corrosion risk a concern in Tm Rural Water District, SD?

Where EPA SDWA compliance data includes lead and copper rule monitoring, violations, or enforcement actions, that information feeds into the Operational Stress component of the MISI score. Munimetric does not fabricate lead pipe data where public records are silent.

Does Munimetric include PFAS monitoring context for Tm Rural Water District, SD?

Where stored public records include UCMR or contaminant-monitoring summaries, Munimetric displays PFAS monitoring context as public-record evidence. Missing PFAS summaries are treated as missing records, not as non-detections. This context does not change MISI by itself.

What source-water context is available for Tm Rural Water District, SD?

Munimetric displays stored source-water and supply context where public drinking-water identity records are available. Source-water context helps explain treatment and supply exposure, but missing source records remain explicit rather than inferred.

Why might water rates be increasing in Tm Rural Water District, SD?

Rate pressure can reflect capital investment needs, a declining customer base, revenue fragility, affordability constraints, or parent-government fiscal stress. The Rate Constraint and Revenue Fragility score families specifically measure these pressures where data is available from public financial disclosures.

What does the MISI score mean for Tm Rural Water District, SD?

The MISI score (42.9/100) is a composite measure of structural risk across five families: Operational Stress, Capex Pressure, Revenue Fragility, Rate Constraint, and Governance Risk. The headline remains a blended structural stress composite rather than a pure physical-condition index. The current methodology also downweights factors that are nearly universal or very rare in the frozen national reference population, so one common contextual factor does not dominate the headline by itself. Higher scores indicate more structural stress. It is deterministic and source-backed, not a credit rating.

Executive context

What the Data Suggests

Tm Rural Water District, SD is a smaller community water system, serving approximately 4,250 residents. The current reading places the system in a zone of moderate-to-elevated stress that goes beyond normal operating variation.

The score is being driven mainly by Operational Stress, which is running high in the model, with Capex Pressure adding another heavy layer of pressure. That combination suggests strain is showing up across core system functions, not just one isolated dimension.

7 active stress signals are attached to this system, including 5 at high severity. That signal mix points to a system where several warning indicators are firing at once, not just one extreme outlier.

Within Community · < 25k · Surface, this system ranks around the 96th percentile on measured stress, placing it near the top of peer-group stress.

Recent observations suggest the system has been relatively steady rather than sharply improving or deteriorating — the current picture looks more like persistent underlying pressure than a sudden shift.

This summary is based on structured, source-backed public data and is intended for research and monitoring only. It is not investment advice, a credit opinion, or municipal advisory guidance.
