What is in the water
Our water filtration coverage in Louisiana runs to 339 ZIP codes in 167 cities. Large municipalities buy and treat water at scale and publish an annual quality report for the whole system, so what arrives at the tap is well documented — and the variation that is left is mostly in the pipework between the main and the tap.

What this site is
ClearTapCall is a referral service, not a contractor and not a laboratory. We connect homeowners with independent contractors for filtration and treatment installation. Contractors are required to hold whatever credential their state or municipality demands, and treatment equipment plumbed into a supply is often a permitted alteration — ask to see the permit. We carry out no work, we sell no equipment, we test no water, we do not set prices, and we never charge homeowners anything. Nothing here is a statement about the water at any address, and no page recommends a product.Checking a credential in Louisiana
Louisiana licenses are issued by the State Plumbing Board of Louisiana, which publishes a public search you can use before work begins.

What that coverage looks like
Jefferson Parish County holds 88 of the 339 ZIP codes we cover in Louisiana, and New Orleans 61 of those. A supply that large is usually one system with one published quality report; the remaining 52 counties contain many smaller systems, each with a report of its own.
How a water filtration job goes
Filtration is chosen from a test result, not from a taste. Hardness, iron, sediment and chlorine each call for different equipment, and a cartridge sized for one does nothing for the others. The order is always the same: find out what is in the water, then decide what has to come out of it, then size the equipment for how much water the house actually uses.
What the call asks about water filtration
- Whether the supply is a public system or a private well, because the testing route is different.
- What the water is actually doing — staining, scale, smell, taste, cloudiness.
- Whether there is a test result already, from the annual report or from a lab.
Every Louisiana city we route in
60 cities, ordered by the share of housing built since 2000. Plumbing age decides what the water picks up between the main and the tap. Each page carries that city’s own numbers and the ZIP codes we route there.
