Website for a water treatment company in Kazan: diagnostics by symptom, before-and-after on real sites, a system configurator with an estimate and a 289-item catalogue with prices.

01The brief
Sell a proven result,
not a filter
The company ran on a website builder: template blocks and promises that sound the same at every filter seller. We rebuilt it from scratch around how the company actually works: a water analysis first, then a selection based on the numbers and an estimate that doesn’t change after work starts.
01
Analysis first
Every block leads to a water sample: a symptom, the substance, the numbers and the treatment stage that removes it.
02
Sites with numbers
Before-and-after on installation photos, with values from the lab reports: iron, hardness, odour.
03
Open prices
A 289-item catalogue with prices and filters, product pages and brands with dealer certificates.
04
Two-minute selection
A configurator builds the scheme, the equipment list and a price range — from an analysis or from symptoms.
- Pages
- Home, catalogue, product page, selection, installations
- Catalogue
- 289 items — moved from the old shop by a script
- Stack
- HTML, CSS and JavaScript, no website builder
- Status
- Built and being prepared for launch
02Diagnostics
Every symptom
has its substance
The site’s main interactive. Pick what you notice at home and see which substance it is, how far above the norm it goes and which treatment stage removes it. A glass of water changes colour with the answer. Try it — the data is the same as on the site.
What you notice
5mg/dm³
above the normnorm 0.3
Why. Dissolved iron oxidises in the air: rusty sediment, stains on plumbing, a metallic taste.
Fix: an iron removal filter on catalytic media
The values are typical examples from the site. Only a lab analysis shows what is in a particular water.
03Before and after
Photos from the sites,
numbers from the lab
On the left, the spot before installation; on the right, the finished system. Every site has a task, a solution and a result, and on the website all of them also sit on a map of Tatarstan.


Sites
Iron and hardness
Stolbishche
- Task
- High iron content — 5 mg/dm³
- Solution
- Two columns: 1054 and 1252
- Result
- Iron 0.3 mg/dm³, hardness 0.5 mmol/dm³
04Selection
A system in two minutes —
with a scheme and an estimate
A few questions about the site, the source, the water and the flow — and the screen shows the treatment scheme, the equipment at catalogue prices and a turnkey price range. An engineer confirms the final estimate with an analysis.
- 01Works from an analysis — or from symptoms if there is no analysis yet
- 02Accounts for flow rate, boiler-room height and drainage
- 03The specification can be printed or shared as a link

05Catalogue
289 items
with open prices
We moved the catalogue from the old online shop by script: prices, photos and specs update with one command rather than by hand. Filters by task and brand, product pages with installation terms and dealer certificates.


06Analysis and districts
Numbers first,
then equipment
Three levels of analysis — from three parameters to a full 25-parameter chemical test — and test tubes that set the source water and the treated water against the sanitary limit. Below is a district table of what was found in the neighbours’ water, compiled from 161 installations the company has published on its Telegram channel in 2022–2026.


07How it works
Six steps
and a service calendar
The way from request to clean water, step by step, with the price of each stage. Then the guarantees, what maintenance includes and a first-year calendar: when to change cartridges and the membrane, when to top up salt.


08On the phone
The same site
in one hand
Diagnostics, before-and-after and selection are laid out for a thumb, and the “Call an engineer” button is always at the bottom of the screen.
Outcome
What the company received
The site is built and being prepared for launch on the company’s domain.
- A new website without a builder
