Punaluʻu Water & Wastewater Sustainability Initiative

Keeping the water safe for Punaluʻu — the honest work behind a small community system.

We’re the regulated water and wastewater system that serves this corner of Kaʻū. The infrastructure is old, the community it serves is small, and a 50-year-old system serving a small rural community can’t fund itself the way a big-city utility can. Here’s the situation, plainly — and what it’ll take to do it right.

01  /  Why This Matters

Why this system matters

Water is the one thing a community can’t do without. For the homes and families connected to this system, it’s not a convenience — it’s daily life. Reliable, safe water is the baseline everything else sits on.

Safe water is public health

When a water and wastewater system works, nobody thinks about it — that’s the goal. Keeping it compliant with Hawaiʻi Department of Health standards protects everyone connected to it.

It serves a real, rooted community

This isn’t a system for a resort or a subdivision. It serves an established rural community in Kaʻū — kūpuna, families, and neighbors who’ve been here a long time and plan to stay.

Small and rural means it needs care

Systems like this don’t have the scale a city has. That’s exactly why they need thoughtful planning and public partnership to stay safe for the long haul. That’s the work.

02  /  The Current Problem

The system is aging — and the numbers don’t add up on their own

Let’s be straight about it. Most of this infrastructure is more than 50 years old. It’s been kept running, but “kept running” isn’t the same as “built to last another generation.” Pipes, pumps, and treatment don’t last forever, and the bill for renewing them is real.

Here’s the honest part: what the system takes in today isn’t enough to fund the repairs and upgrades it needs. That’s not a scandal — it’s the math of a small rural utility. Spread the fixed cost of running a whole water system across a small number of connections, and the money simply doesn’t stretch far enough. This is the same challenge small water systems face all over rural America, and it’s exactly why public funding programs for these systems exist.

“A small system serving a rural community carries the same public-health responsibility as a big one — with a fraction of the ratepayers to fund it. That’s the honest challenge, and it’s a solvable one.”

03  /  The Cost Gap

Why a small connection base is a real challenge

A water system costs roughly the same to run whether it serves thousands of homes or a few dozen. The treatment, testing, pumps, compliance, and maintenance — those costs are mostly fixed. They don’t shrink just because the community is small.

1Fixed costs

Fixed costs don’t get smaller

Testing, treatment, and upkeep cost what they cost. A small system pays for a full water operation with a small base to support it — that’s the whole puzzle in one sentence, and it’s basic math, not anyone doing anything wrong.

2Ratepayers

Rate shocks aren’t the answer

You could technically cover the gap by raising rates a lot — but that would fall hard on the households here, many of them kūpuna and working families. Protecting ratepayers matters. That’s not the path.

3The solution

Public funding is built for this

State and federal programs exist specifically to help small, rural, regulated systems make major repairs without crushing the people they serve. Using them the right way is the responsible move.

Why small systems can’t go it alone

A big-city system
One full set of fixed costs
Split across thousands of connections — a few dollars each.
A small rural system (like ours)
The same full set of fixed costs
Split across a small connection base — a heavy load on each one.

Same job. Same standards. Far fewer households to share the cost. That’s the gap public funding is designed to close.

What this means for households

Safe, reliable water at a fair price — without a rate shock landing on a small group of neighbors.

What this means for the community

A stable, compliant public utility that stays ahead of problems — not a crisis waiting to happen.

04  /  What’s Needed

What this system needs now

i.

A clear-eyed assessment

Know exactly what’s aging, what’s urgent, and what can wait — a real condition report, not guesswork.

ii.

Core repairs & upgrades

Renew the aging pieces that protect water quality and keep the system compliant with Department of Health standards.

iii.

Public-purpose funding

Pursue the state and federal programs designed for small rural systems — so the cost of doing this right doesn’t land on a small group of households.

iv.

A long-term plan

Move from patch-and-pray to a real asset-management approach, so the system stays safe for the next generation, not just the next year.

05  /  Funding Approach

A public-purpose approach to funding

The right way to fund a small community water system isn’t to lean on ratepayers — it’s to use the public programs built for this exact situation. Across the country, safe rural water is treated as a public good, and there’s real funding behind that idea.

  • Federal rural water infrastructure programs
  • State drinking-water and clean-water revolving funds
  • County and community conservation and public-benefit programs
  • Where it fits, community and nonprofit partners set up to steward this kind of support
Every dollar is tied to one thing — keeping safe, reliable water flowing to the community this system serves.
PWS · Public-Purpose Funding Approach

To be clear about what this is not: there’s no rate shock, no donation drive, and no development. It’s the responsible use of public infrastructure funding built for small rural systems — the same tools communities like ours rely on across the state and the country.

06  /  The Plan

The plan to get there

A measured, responsible path — steady the system and get the facts first, then renew it and keep it that way.

1 Stabilize & assess 2 Renew & sustain
Phase 1

Stabilize and assess

First, steady the system and get the facts. Complete a full condition assessment, address the most urgent public-health and compliance priorities first, and line up the funding that fits. No drama, no shortcuts — just the honest groundwork.

Phase 2

Renew and sustain

Then, with a plan and funding in place, renew the aging infrastructure and put a long-term asset-management approach in place — so the system stays safe, compliant, and affordable for the people it serves, for the long run.

07  /  Our Commitment

Our commitment

Here’s what we’ll hold ourselves to.

Keep the water safe

Public health comes first — full stop. This system will meet the standards the community deserves.

Be straight with people

No spin, no hype. When there’s a problem, we’ll say so plainly — and say what we’re doing about it.

Protect the households

We’ll pursue public funding built for small rural systems precisely so the cost doesn’t fall on a small group of neighbors.

Do right by the place

This water runs through a place people love and have cared for across generations. Caring for it responsibly is the job — and we intend to do it well.

08  /  Questions

Frequently asked questions

Is this a public utility or a private company?
It’s a regulated public water and wastewater utility, operating under Hawaiʻi Public Utilities Commission oversight and held to Hawaiʻi Department of Health drinking-water standards. That means its rates, service, and operations are publicly accountable.
Why does a small water system need outside funding?
Because a water system costs about the same to run whether it serves a city or a small community — and this one serves a small connection base. Spread across roughly 92 connections, the cost of major repairs is more than local revenue can carry. Public funding programs exist specifically to help small rural systems handle exactly this, without overburdening the households they serve.
Will this raise my water bill?
Protecting ratepayers is a core goal. The whole reason for pursuing public-purpose funding is so the cost of major repairs doesn’t land as a rate shock on a small group of households. Any rate decisions run through the PUC’s regulated, public process — not something done quietly.
Is this about building or expanding anything?
No. This is about repairing and sustaining the existing system that serves the current community. It’s maintenance and public health — keeping safe, reliable water flowing to the homes already connected. It is not a development project.
How old is the infrastructure, really?
Much of the core system is more than 50 years old. It’s been maintained and kept in service, but infrastructure of that age needs real renewal to stay safe and compliant for the long term. Being honest about that is the first step to fixing it.
Who benefits from this work?
The people connected to the system — the families, kūpuna, and households who rely on it every day. Safe, reliable, fairly priced water for this community is the entire point, and the measure of whether we’ve done the job right.
