Cahaba Water Co.
Treatment level · Whole home

Chlorine handled at every tap. Nothing you didn't ask for.

One carbon filter on your main line. It reduces chlorine taste and odor at every tap in the house.

Cahaba Whole Home Essential is a treatment level. It is not a package, and it is not a size. We put a carbon filter on the main water line coming into your house. So the shower, the bath and the laundry get the same water as the kitchen. A softener is not automatically included. A drinking-water system is a separate choice you can make later.

Size is the other decision — S, M, L or XL. We set it from measurements taken at your house.

    Full bypass

    The house keeps running during service. The bypass is the same at every treatment level.

    The tank rinses itself clean, a cycle called a backwash. It runs on the water you use, not on a clock. There are no cartridges to change.

    Jacobi AquaSorb activated carbon

    This is the right material for chlorine. How much of it goes in the tank is the size question, not this one.

Two decisions

This page answers one of them.

Treatment level and system size are two separate questions. Each one gets its own answer. A big house does not automatically need more treatment. A house that wants full treatment does not automatically need a big system.

01

Treatment level

What does this homeowner want or need treated?

Answered here. Cahaba Whole Home Essential is carbon filtration for the whole house. It reduces chlorine taste and odor at every tap. Softening and drinking-water treatment are not part of it.

02

System size

How much water does this house use at its busiest moment?

Answered separately, at your house. We measure the service line, which is the pipe bringing water in from the street. We count the fixtures that actually move water. We measure your water pressure two ways: standing still, and running. Never square footage, home value or ZIP code.

SStandard Flow
MEnhanced Flow
LHigh Flow
XLEstate Flow

A finished build carries both answers in its name. Treatment level first, then size.

Cahaba Whole Home Essential ‑ M

Essential is not the small system. Take a big house with six bathrooms, where the only complaint is the chlorine taste. Essential at XL can be exactly right: a large system doing one job very well. Now take a small house with two bathrooms, where the owner wants everything: filtered water at every tap, softer water, our best drinking-water system, and UV. That house needs a wider treatment level at a smaller size. Neither one is an upgrade over the other.

What this level treats

The chlorine you can smell in the shower.

What carbon does well, and what it does not.

Central Alabama Water (formerly Birmingham Water Works) disinfects the water with free chlorine. That is effective, it is required, and it is why the water is safe to drink. It is also why a hot shower can smell like a swimming pool.

A carbon filter on your main line reduces that chlorine before it reaches any tap. The tank also rinses itself out to the drain, a cycle called a backwash. It runs on the water you use, not on a clock. Nothing needs changing on a schedule, and no cartridge clogs up and slows your water down.

Where we are careful. Carbon reduces chlorine taste and odor well. The musty taste some summers bring is a different matter. That taste comes from geosmin. When the whole house is running, the water moves past the carbon too quickly for much contact time. So a whole-home filter reduces that musty taste only partially. An under-sink reverse-osmosis system is what reliably fixes taste at the tap you drink from. We would rather tell you now than let you find out in August.

What the level specifies

And what it deliberately leaves open.

Every row below is one of two things. Some are treatment answers, which this level gives. The rest are size answers, set when we visit your house. We do not guess at those to fill the page.

Who this level is for

And when a different one is the honest answer.

When Essential fits, and when it does not.

Essential is the right level if
  • Chlorine in the shower or the laundry is what you notice
  • You want the whole house treated, but nobody has shown you that you need a softener
  • Your hardness test does not support fitting a softener
  • You would rather add a drinking-water system later. It would be its own decision, at its own price
Look at a different level if
  • Your test and your goals call for a softener. That is Cahaba Whole Home Complete Whole home
  • You want a system designed around your house. It can add UV, pressure control or monitoring. That is Cahaba Whole Home Signature Whole home
  • Drinking water is your only real concern. A Cahaba under-sink RO Drinking water on its own may be the whole answer
  • You are on a private well. That is a different problem, and we will say so

None of those is a bigger system. They are different answers to the treatment question. The size question is answered the same way every time.

Cahaba Whole Home Essential — what we will and will not say

Reduces chlorine taste and odor at every tap in the house

Protects equipment and fixtures further down the line from constant chlorine

Sized to measured peak demand and pressure, never to square footage

Not a softener — it does not reduce hardness

Reduces summer musty taste only partially when the whole house is running

Not presented as a certified complete system unless that assembly is documented as one

Not a statement that Birmingham water is unsafe. It is disinfected, monitored and meets the standards

Questions

Questions we get about this.

Does Cahaba Whole Home Essential include a water softener?
No. Softening is not automatically included at this treatment level. A softener is not required in every Birmingham home. Whether one is worth fitting comes from a measured hardness result, and from what you actually want changed. It does not come from the treatment level you pick. Where testing and goals justify softening, that is Cahaba Whole Home Complete.
What size is Cahaba Whole Home Essential?
Essential is a treatment level, so it has no size of its own. Size is the second decision, and we make it separately. The four sizes are S Standard Flow, M Enhanced Flow, L High Flow and XL Estate Flow. We set the size from the incoming service line, from the fixtures that actually move water, and from measured static and dynamic pressure. A finished build is named like Cahaba Whole Home Essential — XL.
Can I add a drinking-water system to Cahaba Whole Home Essential?
Yes. A Cahaba under-sink reverse-osmosis system can be added separately, at its own published installed price. Whole-home carbon and an under-sink RO answer different questions. Carbon reduces chlorine taste and odor at every fixture in the house. The RO is what reliably fixes taste at the tap you drink from.
What does Cahaba Whole Home Essential cost?
Quoted after sizing. We do not publish a whole-home price. The price follows the build, and the build follows the measurements taken at your house.

Right level. Now the size.

Size is settled at your house, not at a desk. We look at the pipe coming in from the street, the fixtures, and the measured pressure. Often the answer is smaller than people expect.
