💧 RTT Facilities — Asset Class: Water

Life, Health, and Public Trust

This document defines the Water (Potable) asset class within the RTT Facilities domain.

It is grounded in the RTT Facilities Playbook and inherits all canonical Facilities frameworks, including lifecycle, scoring, propagation, intervention, modernization, capital, and governance.

1. Asset Class Purpose#

Potable water systems provide the most fundamental public service.

They enable:

• Human survival and public health
• Fire protection and emergency response
• Healthcare, sanitation, and food systems
• Economic activity and daily life continuity

Water failure immediately threatens life, health, and public trust.

2. Scope of the Water Asset Class#

This asset class includes infrastructure supporting:

• Source water protection (surface and groundwater)
• Treatment and purification facilities
• Storage (tanks, reservoirs)
• Distribution networks
• Monitoring, control, and telemetry systems

Both physical and control components are included where failure impacts continuity.

3. Lifecycle Considerations#

Water assets follow the canonical Facilities lifecycle:

• Design — source protection, capacity, redundancy, climate resilience
• Construction — safety, durability, regulatory compliance
• Operation — quality, pressure, reliability
• Maintenance — inspection, cleaning, component renewal
• Modernization — resilience, treatment upgrades, demand adaptation
• Decommissioning — safe transition and supply continuity

Lifecycle misalignment is treated as a governance risk, not a utility issue.

4. Risk & Degradation Patterns#

Common water‑system risk patterns include:

• Gradual pipe and storage degradation
• Source contamination or depletion
• Capacity mismatch during droughts or emergencies
• Dependency on electrical power for treatment and pumping
• Deferred modernization masked by reactive maintenance

These patterns are assessed using Facilities scoring frameworks.

5. Scoring Integration#

Water assets are assessed using:

• Drift Scoring — infrastructure aging, quality deviation
• Harmonics Scoring — pressure oscillation, pump cycling stress
• Propagation Modeling — dependency on power, wastewater, and transportation

Scores inform intervention timing and modernization planning.

6. Corridor Classification#

Water corridors may include:

• Transmission mains and trunk lines
• Treatment and storage service areas
• Shared utility corridors
• Source‑to‑treatment protection zones

Corridors are classified using the Facilities corridor standard and may cross jurisdictions.

7. Cross‑System Propagation#

Water systems are tightly coupled to:

• Electrical systems — treatment and pumping
• Wastewater systems — sanitation and contamination risk
• Public buildings — healthcare, shelters, governance
• Transportation — access for maintenance and emergency response

Water failure rapidly propagates into health and safety crises.

8. Intervention Patterns#

Typical water‑system interventions include:

• Preventive — monitoring, leak detection, source protection
• Planned — treatment upgrades, capacity expansion
• Emergency — boil advisories, temporary supply, rapid stabilization

Intervention class is governed by Facilities thresholds and GHQ oversight.

9. Capital & Audit Integration#

Water modernization is aligned with:

• Facilities modernization cycles (10 / 20 / 50‑year)
• Capital‑audit integration requirements
• Public health and trust priorities
• Corridor‑level risk classification

Deferred water modernization is explicitly auditable.

10. Relationship to Domain Extensions#

Future domain extensions may include:

• Drought and climate resilience
• Advanced treatment and reuse
• Source‑water protection frameworks
• Regional supply interconnection

All extensions inherit Facilities substrate definitions.

11. Canonical Status#

This asset class definition is canonical.
