Water Treatment
Services in
Westlake, FL

Westlake homes get public water from the Seminole Improvement District, which buys treated water from Palm Beach County Water Utilities. Almost every house here was built since 2018, so the questions are different from older towns: what the County's water carries, what the builder installed, and whether it's set up right. A free test at your own faucet tells you which of those applies to your house.

Your water bill says SID, but the water itself comes from the County. The Seminole Improvement District is the only retail water provider inside the City of Westlake, and its boundaries match the city's. SID doesn't treat water. It buys finished water from Palm Beach County Water Utilities and runs its own sampling across Westlake. SID's 2024 water quality report states that its drinking water complies with federal, state and local rules. To see what's in it, you read SID's report alongside the County's.

Westlake is Palm Beach County's newest city. It was incorporated on June 22, 2016, on roughly 4,000 acres of former Callery-Judge citrus grove along Seminole Pratt Whitney Road, north of Loxahatchee Groves and Lion Country Safari. The first residents moved in early in 2018. The 2020 census counted 906 people, and Census estimates put the city close to 6,000 by 2023, and new neighborhoods are still being platted.

The water reaching those homes is groundwater that Palm Beach County pumps from wells about 150 feet deep in the surficial aquifer and treats at its plants before selling it to SID. The County disinfects it with chloramine, and SID passes it through its own pipes to your meter. So a Westlake homeowner's water questions come down to three things: what the County's supply carries, what happens to it in a brand-new home's plumbing, and whether any equipment the builder left behind is actually doing its job.

What the Latest Reports Show for Westlake Water

From the Seminole Improvement District 2024 Water Quality Report (PWS 4504903), the Palm Beach County Water Utilities 2024 Water Quality Report (PWS FL4504393) and the EWG Tap Water Database
🟡 Found in County Supply · Federal Limit Not Yet in Force

PFAS (PFOS and PFOA)

The County's November 2024 federal monitoring found PFOS averaging 13.5 ppt (up to 18 ppt) and PFOA averaging 6.7 ppt (up to 7.3 ppt). EPA set a 4 ppt limit for each in 2024, which utilities don't have to meet yet, so this isn't a violation today. The County is planning nanofiltration at one of its plants partly to treat for PFAS.

Fix: Reverse Osmosis at the Kitchen Tap
🟡 No Federal Limit · Above EWG Guidelines

Chlorate & Chromium-6

EWG's database lists the County system at about 462 ppb chlorate and 0.105 ppb hexavalent chromium. Neither has a federal limit of its own (EPA regulates total chromium at 100 ppb). Both sit above EWG's stricter guidelines of 210 ppb and 0.02 ppb. Chlorate is a byproduct of the chlorine-based disinfectants used in treatment.

Fix: Reverse Osmosis
🟡 Under the Federal Limit · Above EWG Guideline

Disinfection Byproducts

EWG lists haloacetic acids (HAA5) in SID's system at 26.3 ppb, under EPA's 60 ppb limit, and the system was in compliance in EPA's latest quarterly review. EWG's own guideline is far lower. These byproducts form as chloramine reacts in the pipes, and you also breathe them in a hot shower, which is why carbon at the main line is the usual answer.

Fix: Whole-House Catalytic Carbon
🔵 Set by the County · Taste & Softener Resin

Chloramine

Chloramine keeps the water disinfected across SID's newer pipe network, and it's behind the faint pool smell in a glass of tap water. Ordinary carbon doesn't remove it well; catalytic carbon is built for it. If you have a softener, removing chloramine first also helps the resin last.

Fix: Catalytic Carbon Filter
🔵 Not Published · Measured at Your Tap

Hardness

Neither SID nor the County publishes one hardness figure for Westlake, and the County's plants don't all use the same treatment process. So any hardness number you've seen quoted for Westlake is a guess. A reading from your own faucet settles whether a softener earns its place, and what size.

Fix: Test First, Then Decide on a Softener
🔵 Comes Down to Fixtures, Not Pipe Age

Lead

Nearly every Westlake home was built long after the 1986 lead-solder ban. In SID's June 2024 round, 39 of 40 tap samples were under the 15 ppb lead action level. The one that wasn't came from a fixture inside a school, past the district's meter. Faucets and fittings still matter, which is why we offer a lab lead test if you want one.

Optional: Under-Sink RO or NSF-53 Filter

Water Treatment Systems We Install in Westlake

🔬

Reverse Osmosis Systems

Our 5-stage, NSF/ANSI-certified reverse osmosis system mounts in the kitchen cabinet and treats the one tap you drink and cook from. It's built to reduce PFAS, chromium-6 and lead, and it's the system we usually suggest first here, given the County's PFAS, chlorate and chromium-6 numbers.

From $799
🏠

Whole-House Carbon Filtration

Catalytic carbon at the main line, designed to cut chloramine and reduce disinfection byproducts at every tap and shower. It also shields softener resin. How whole-house filtration works.

From $1,495
💧

Water Softener Installation

If your reading shows enough hardness to leave scale, we size the softener to that number and your household's use. Fleck or Clack valves, resin rated for chloramine (10% crosslink), 5-year valve cover. If it doesn't, we'll say so.

From $1,495
💎

Complete 3-Stage System

When your test shows hardness as well as the chloramine and drinking-water questions, the three stages go in together in one appointment. Our water purification systems page shows how each stage hands off to the next.

From $3,200

Just closed on a Westlake home? Before you buy anything, open the garage or utility closet and see what's already there. Many new homes come with a softener, a filter or an RO faucet, and some come with nothing. Write down the brand and model, check whether the bypass valve is open or closed, and book a test. We'll check the water coming in and the water coming out of the equipment, so you know whether it needs a setting change, a service or a replacement.

Builder-Installed Softeners and Filters: Check Before You Replace

In an older town, the first water question is usually the pipes. In Westlake it's the equipment. Homes here went up in phases from 2018 on, by Minto and by other builders such as Kolter at Cresswind and Label & Company at Sky Cove, and what came with each house varies. Some have a softener loop and nothing on it. Some have a softener that was set up at the factory default, or left on bypass after the final inspection. Some have an RO faucet with cartridges nobody has changed since closing.

A softener set for the wrong hardness wastes salt and water, or lets scale through. It's one of the most common calls we get: the unit works, but its programming doesn't match the water. Our article on whether your softener is programmed correctly covers the warning signs. A filter whose carbon has run out simply stops doing anything, with no warning light.

So before you spend money on a new system, let us test both sides of what you have. If it's sound, a reset and a fresh cartridge may be all it needs. If it's undersized or the wrong type for chloramine water, you'll know why before we quote a replacement.

City Water Surrounded by Wells: How Westlake Differs From Its Neighbors

Drive a few minutes east into The Acreage or south into Loxahatchee Groves and many homes run on private wells. Those owners deal with iron stains, sulfur smells, very hard raw water and the occasional bacteria problem, and their systems often include iron filters, aeration and UV lights. Westlake is different. Every home inside the city limits is on SID's treated public water, so you're starting from water that has already been treated and disinfected.

That's why the advice you hear from neighbors on wells doesn't carry over. A Westlake home rarely needs iron removal or UV. The things worth treating here are what the County's supply carries (chloramine, its byproducts, and the PFAS, chlorate and chromium-6 levels above), plus hardness if your reading shows it. Our guide to well water vs. city water in Palm Beach County explains why the two need different equipment.

For most Westlake households that means an under-sink RO for drinking and cooking, whole-house catalytic carbon if chloramine taste or shower comfort bothers you, and a water softener when the hardness test justifies it. There's no reason to treat irrigation water, so lawn lines stay off the system.

What Happens at a Westlake Water Test

Our free in-home water test takes about 20 minutes. We measure hardness, chloramine, iron, pH and total dissolved solids at your kitchen tap. If there's equipment in the house, we test before and after it. A lead check of your faucets and fixtures by a certified lab is included free if you want one. The point is numbers from your house, not from a report covering thousands of homes.

Then we put your readings next to SID's and the County's reports and recommend only what they support. An under-sink RO runs $799–$1,200 installed; whole-house carbon starts at $1,495; a softener is $1,495–$2,500; the full carbon, softener and RO setup is $3,200–$5,500.

Most standard systems can go in the same day. Water Wizards is a local Palm Beach County company out of Delray Beach, so when a cartridge is due or the salt runs low, you reach the people who installed it.

Westlake Water FAQ: SID, PFAS and Builder Equipment

All three play a part. The Seminole Improvement District is the retail provider, so it sends your bill and owns the pipes to your meter. SID buys its water already treated from Palm Beach County Water Utilities under a long-term agreement and does its own sampling around Westlake. The City of Westlake doesn't run a water utility; its boundaries simply match SID's.

Both. SID's annual report covers what it samples in Westlake's own pipes, such as lead and copper at customer taps. The County's annual report covers the water as it leaves its plants, including its PFAS monitoring. Look for SID's report under public water system 4504903 and the County's under FL4504393.

Yes. SID's 2024 report states that it complied with federal, state and local regulations, and the County reported no water quality violations in 2024. Meeting the law isn't the same as matching every independent guideline: the County's PFAS results are above EPA's new limits that aren't in force yet, and chlorate, chromium-6 and haloacetic acids are above EWG's stricter guidelines. Whether that's worth treating at your tap is your call, and a test gives you the numbers to decide.

Not before testing it. Many builder units are fine but set up generically, left on bypass, or missing a carbon stage, which matters on chloramine water. We test the water going in and coming out, check the settings and resin, and tell you whether it needs adjusting, servicing or replacing. We service every brand, so you don't need to switch to ours.

Use your own reading. SID and the County don't publish one hardness figure for Westlake, and countywide numbers you'll see online vary widely. Program a softener from a hardness test taken at your tap, then confirm it's working with a test strip on the softened water. If you don't have a reading, our free test gives you one.

In November 2024 sampling at its plants, the County found PFOS averaging 13.5 ppt, with a high of 18 ppt, and PFOA averaging 6.7 ppt, with a high of 7.3 ppt. EPA set a 4 ppt limit for each in 2024; utilities aren't required to meet it yet, so it isn't a violation. If you'd like PFAS lower in your drinking water now, an RO system at the kitchen tap is the practical option. Our guide to PFAS in Palm Beach County water explains what to look for in a system.

That's a scheduled chlorine flush. SID has posted notices about periodic drinking water line flushing in July, and the County switches its system from chloramine to free chlorine for about three weeks each January and July as routine maintenance. The chlorine smell is stronger during those weeks and goes back to normal afterward. Catalytic carbon handles both chlorine and chloramine. Our article on how chlorine and chloramine differ goes further.

Both show up in the County's supply. Chlorate forms when chlorine-based disinfectants break down during treatment and storage. EWG lists about 462 ppb against its 210 ppb guideline; there's no federal limit. Hexavalent chromium (chromium-6) can occur naturally in groundwater. EWG lists about 0.105 ppb against its 0.02 ppb guideline; EPA has no limit for chromium-6 itself and caps total chromium at 100 ppb. An under-sink RO reduces both at the drinking tap.

It's low on the list, but not off it. Nearly all Westlake homes were built long after the 1986 ban on lead solder, and 39 of SID's 40 tap samples in June 2024 were under the action level. The one exception came from a fixture inside a school, which shows how a single faucet can matter. If you want certainty for your kitchen tap, we'll collect a first-draw sample from it and have a certified lab test it free.

Almost certainly not. Many homes in The Acreage and Loxahatchee are on private wells, where iron, sulfur and bacteria are real concerns. Westlake homes are on SID's treated, disinfected public water, so iron filters and UV usually aren't needed. Your shortlist is RO for drinking water, carbon for chloramine, and a softener if your hardness reading supports it.

Installed prices: under-sink RO $799–$1,200, whole-house catalytic carbon from $1,495, a water softener $1,495–$2,500, and carbon plus softener plus RO $3,200–$5,500. Repairs on an existing system are quoted after we see it. Every quote follows a free water test, and financing is available on all systems.

Plan on 2–4 hours for a softener or a whole-house carbon filter. A three-stage install runs 4–6 hours. Same-day installation is usually possible across Westlake; call 561-352-9989 to check availability.

Check the salt level once a month and top it up. Clean the brine tank once a year and test the softened water with a strip. Book a professional valve service every 5–7 years; 10% crosslink resin generally lasts 10–12 years before it needs replacing. RO cartridges and carbon media follow their own schedule, and we can handle filter changes and salt delivery to 33470 on a recurring plan.
