A water and wastewater system has fixed costs that do not shrink when the number of users is small. Operating, repair, reserve, and replacement obligations remain — and they must be shared across the people the system serves. When too few users carry those costs, the system cannot remain financially or operationally sustainable.

1. Fixed costs, shared unfairly

Treatment, monitoring, compliance, maintenance, and reserves cost roughly the same whether the system serves a few connections or many. With too few users, each one shoulders an unsustainable share — and the system still falls short of what it needs.

2. Reserves and replacement

Responsible utilities set aside reserves to replace aging components before they fail. A user base that is too small cannot fund those reserves, which pushes the system toward reactive, emergency repairs instead of planned, lower-cost renewal.

3. Long-term reliability and compliance

Regulatory and safety standards do not scale down for small systems. Without a sustainable base of users and revenue, PWS faces genuine long-term reliability and compliance risk — the kind that ultimately affects everyone who depends on it.

A stable, adequate user base is not a growth ambition — it is the condition required for the system to meet its safety, reserve, and replacement obligations over time.
