Which Texas water systems border which, from EPA's own service area boundary layer, and what the
published figures say across each border. **A screen, not a recommendation**: nothing here says two utilities
should merge and nothing here is a feasibility result.

## What "bordering" means

Two systems are listed as bordering when their service area outlines come within **1.11 km**
of each other. That is a proximity test and not a touch test, because the boundary layer is simplified by about
a kilometre at acquisition and simplification moves vertices — an exact touch test on these bytes would be a
question about our own simplification rather than about the world. It is not a statement that two systems share
a pipe or an interconnection: nothing in this corpus knows about pipes.

## How EPA got these shapes

| Boundary basis | Systems | With a neighbour | Mean neighbours |
|---|---:|---:|---:|
| published | 2639 | 2321 (88%) | 4.29 |
| unstated | 4 | 2 (50%) | 2.25 |
| modelled | 2 | 1 (50%) | 8 |



## The pairs

7201 bordering pairs. Ordered by how many times larger one side is than the other, and by nothing else — a composite score over size, loss and compliance would be a judgement about how much one is worth against another, and this corpus has none to offer.

**Computed over EPA's whole national layer, before any filter to this site.** 7201 borders reach
this state's drawn systems: 3043 of them name a system this site publishes no page for, and 29
cross a state line. Until #180 neither kind existed here, because the borders were computed on the map's own
per-state, corpus-filtered extract. A row with an unknown side carries EPA's name for it, its primacy agency
and how EPA got its boundary, and nothing else — no loss, no size, no rates — and it sorts below every row
this site can describe.

**A cross-state pair may not have its loss figures compared, and this page does not compare them.** Crossing a
state line means crossing a primacy agency, and "water loss" is at least three different quantities across the
regulators in this corpus. The loss gap on such a row reads "not comparable", which is a statement about the
two regulators rather than about the two utilities.

| Primacy agency | Endpoints on a cross-state edge | Modelled |
|---|---:|---:|
| TX | 29 | 0 (0%) |
| OK | 15 | 0 (0%) |
| NM | 9 | 1 (11%) |
| AR | 2 | 0 (0%) |
| 6 | 1 | 1 (100%) |
| IL | 1 | 0 (0%) |
| LA | 1 | 1 (100%) |

The modelled share is a fact about each state rather than a national average, so an edge basis is doing more
work on a cross-state row than on any other: its two endpoints are drawn from two different modelled
populations.

† EPA records at least one side of this pair as selling water wholesale to other systems. Two service
populations add only where neither system already serves the other, and nothing in this corpus knows who sells
to whom, so a flagged combined figure is an upper bound rather than a sum.

## Borders to systems this site has no page for

**3043 of these 7201 borders** reach a system this site publishes nothing about. They are
listed separately because the ordering above ranks candidates and a row with one unknown side cannot be ranked
— not because the border is less real. EPA drew both shapes; this corpus holds a filing for one of them. Every
cell about the other side is absent on purpose: this site does not know that system's water loss, its size, its
rates or its compliance record.

## What "together" can and cannot mean

**People and connections add. Prices do not.** A combined rate is not the average of two rates, and a combined
cost of service cannot be computed from two sets of filed figures without the cost allocation neither utility
publishes. That is why there is a combined population column and no combined rate column.

The loss gap is in percentage points between two filed figures for the years each system last filed, which are
not necessarily the same year.
