What makes us the most precise pool water treatment company in Cairo
Precise means the system fits your pool by the numbers, and you can check every one of these before you sign anything.
- Sized to your volume of water. The turnover is worked out from the cubic metres in your pool, and the pump and filter are matched to that figure.
- Hydraulic engineers on our own staff. Structural, hydraulic and MEP engineering is done inside the company. Pipe sizes, flow rates and return positions are worked out by our people.
- Tuned at your pool. Dosing, filtration and circulation get set on site, against your water, rather than from a chart in a catalogue.
- Readings on paper. The water is tested, and the readings are written down and left with you.
- Equipment with a name on it. Hayward, Pentair, AstralPool and Aqua Water Systems, with Schneider Electric on the automation.
- Nothing billed that was not done. Anything beyond the agreed scope gets quoted in writing first, and nothing starts until you agree.
Pool work in Egypt since 2001, from one office in Nasr City
We have worked on pools in Egypt for twenty five years, under one name and one phone number. The office is at 15 El-Lewaa Mahmoud Samy Basha, Al Mintaqah as Sādisah, Nasr City, Cairo Governorate 10506, Egypt. Office hours are Saturday to Thursday, 9am to 5pm. Closed Friday.
We also design, build, maintain and repair pools. That matters on a treatment job, because the filter sits at the end of a loop that runs through the shell, the skimmers, the drain and the buried pipe, and our engineers know every part of that loop.
Turnover sets the size of the whole system
Turnover is the time your plant takes to push one full pool of water through the filter. Take the cubic metres, decide how many times a day that volume has to be filtered, and you have the flow rate. The pump, the filter and the pipe all get chosen from that one number.
Use changes the number. A club pool with a crowd in it all afternoon needs a shorter turnover than a family pool of the same size. Cairo heat and dust add to the load for most of the year.
The run time gets set against the turnover when the system is tuned, so you know how many hours the pump needs and why.
Pipe sizes and return positions
Pipe diameter limits flow. Narrow pipe, tight bends and a long climb up to a rooftop plant room all cut what a pump can push, whatever its rating. So the pipe and the equipment get sized together, on one set of numbers.
Water coming back into the pool takes the easiest route. With the returns aimed badly, the water near the steps, the benches and the corners barely moves, and still water is where algae gets its start. Return positions are part of the sizing for that reason. On an overflow or infinity pool, the balance tank sits in the same loop and gets sized with it.
A filter and a pump chosen as a pair
A filter catches dirt when water passes through it at the speed it was built for. An oversized pump forces water through too fast and fine dirt goes straight back into the pool. A filter too small for the volume loads up within days and the pressure climbs.
The filtration and treatment equipment we fit comes from Hayward, Pentair, AstralPool and Aqua Water Systems. Each pump and filter gets picked against your flow rate, so the pair reaches the turnover in the hours the pump is set to run.
Plant that is too small for the pool gets written up and quoted as new pumps, filters and control panels, with the reason for each one beside it on the quote.
Dosing that follows the water, every hour of the day
Hand dosing corrects the water after it has drifted. An automatic dosing system tests the water continuously and adds small amounts as it moves, so the balance stays inside a narrow band through the whole week. Control runs through Schneider Electric automation, on the same panel as the pumps and the filtration.
Water held in balance is gentle on grout, plaster, metal fittings and the inside of a heater. Water that swings between too much and too little wears all of them down slowly, and the repair bill arrives years later.
Dosing probes drift over time and need checking against a hand test. That check, with the cleaning and the filter, belongs to our weekly maintenance visit on a day you pick.
Salt chlorination or dosed chlorine
A salt pool is still a chlorine pool. A salt chlorinator makes chlorine from mildly salty water as it passes through the cell, in place of chlorine added from a container. We supply and fit salt and chlorine systems both, so the choice follows your pool and how it gets used.
| Salt chlorination | Dosed chlorine | |
|---|---|---|
| Where the chlorine comes from | Made in the cell from salt in the water | Pumped in from a container by a dosing pump |
| What the pool needs | Fittings, lights, ladders and stone suited to salt water | A steady stock of chlorine on site |
| Upkeep | The cell cleaned, and replaced in time | The container refilled and the dosing pump checked |
| A crowded day | The cell sized for the peak number of swimmers | The dose raised the same day |
Salt water is harder on some metals and some stone than ordinary pool water. Before any conversion to salt, the fittings, the heater and the stone around the pool get checked, and you hear at the site visit if they do not suit it.
Water that will not hold its balance, and where the cause usually sits
The symptom shows in the water. The cause usually sits in the plant room or the dosing.
| What you see | Where the cause usually sits | What gets sized or fitted |
|---|---|---|
| Haze that clears for a day or two and comes back | Filter too small, or the pump not running long enough | Filter matched to the volume, run time reset |
| One corner or the steps going green first | Returns aimed badly, water standing still | Returns repositioned, circulation rebalanced |
| Chlorine gone by the afternoon in summer | Sun and heavy use outrunning the dose | Automatic dosing sized for the peak |
| Scale on the waterline tile or in the heater | Water out of balance for months | Dosing control set to hold the balance |
| A strong chlorine smell around the pool | Spent chlorine combined with sweat and sunscreen | Dose and filtration corrected together |
Most of those rows end in the plant room, which is why the chemicals get chosen last.
Readings on record for clubs, hotels and compounds
If you run a shared pool, the water is also a record somebody will ask to see. The Ministry of Youth and Sports closes pools that fail inspection.
On a shared pool, automatic dosing keeps the water inside its band at the busiest hours, and the readings are logged and kept for your inspection file. You get one named contact, a written scope your board can approve line by line, and faults traced to their cause once by our own engineers, so the same pump stops coming back on the budget. Buildings, clubs, hotels and compounds can contract us directly.
Treatment systems on pools other contractors built
We maintain and renovate pools other contractors built, and the plant room comes with them. The first visit covers the water, the installed plant, the pipe sizes and the returns. You get the findings in writing: what to change now, what can wait a season, and what to leave alone.
Sometimes the answer is a larger filter, and sometimes it is a longer run time and two returns turned round, which costs very little. You hear which.
On pools we build: 25 years on the structure, 10 on the waterproofing, 5 on the electromechanical works, in writing. On a repair to another company's pool, the term is agreed per job and written on the quote.
The Cairo locations where we size and tune treatment systems
Teams go out from our Nasr City office six days a week. A treatment system needs adjusting as the seasons change, so a swimming pool company Cairo families trust with one has to be able to come back. These are the places we work.
| Part of the city | Areas |
|---|---|
| East Cairo | Nasr City, Heliopolis, Al Rehab, pools in Madinaty, El Shorouk |
| New Cairo | Fifth Settlement, villa gardens in Katameya, Mostakbal City, New Administrative Capital |
| South Cairo | Maadi, Mokattam, Uptown Cairo |
| West Cairo | Sheikh Zayed, 6th of October |
| Outside Cairo | second homes in Ain Sokhna, the North Coast, El Gouna and Hurghada, the Delta, Upper Egypt |
Large plots in Katameya can put the plant room a long way from the water, and sea air at Ain Sokhna is hard on exposed metal, so both get allowed for at the site visit. Work outside Greater Cairo is confirmed after a site visit.
Who should not buy a treatment system from us
If your water holds its balance from one week to the next and the plant was sized properly when it went in, you need nothing from us today. Save the number for the year the pump gives out.
If you want a drum of chlorine delivered and nothing measured, we are the wrong company, and we will tell you so on the first call.
How the price is decided, after a free site visit
Five things set the figure, and each one has to be seen at the pool.
- Volume of water. The cubic metres, which set the turnover.
- Type of pool. An overflow or infinity pool adds a balance tank to the loop.
- How the pool gets used. A family pool and a club pool in full summer need different turnover and dosing.
- What is already installed. What can stay, and what has to go.
- The plant room. How far it sits from the water, how high, and what pipe runs between the two.
A figure given before those five are known gets corrected later, so we come and look first. The visit and the consultation cost you nothing and commit you to nothing, and the price comes from our own rate book.
Call or WhatsApp +20 102 626 1818 to book the site visit.
Six things to note before the site visit
Ten minutes with a tape and a phone camera.
- The size. Length, width, and the depth at both ends.
- The pump label. A clear photo of the plate on the side of the pump.
- The filter. A photo of the whole filter and its gauge.
- The timer. How many hours a day the pump runs now.
- The busiest day. Roughly how many people swim on it.
- What has gone in. Every product added to the water in the last month.

Frequently asked questions about pool water treatment
My water keeps going cloudy even though I add chlorine. What is wrong? Most often the filter or the circulation is too small for the pool, or the pump runs too few hours. The site visit checks both against the volume of water.
Does a salt pool have chlorine in it? Yes. A salt chlorinator makes chlorine from the salt in the water, so you stop adding it by hand. The cell needs cleaning, and replacing in time.
Can my pool be converted to salt? Often, once the fittings, the heater and the stone around the pool have been checked. If any of them will not suit salt water, you hear that at the site visit.
Do you fit treatment systems on pools you did not build? Yes. We look at the water, the plant, the pipe sizes and the returns first, and you get the findings in writing before any quote.
Can you keep readings for our inspection file? Yes. On club, hotel and compound pools the readings are logged and kept for your inspection records.
What warranty covers the treatment equipment? On pools we build: 25 years on the structure, 10 on the waterproofing, 5 on the electromechanical works, in writing. On a repair to another company's pool, the term is agreed per job and written on the quote.
How much does a treatment system cost? It depends on the volume, the pool type, how the pool gets used, what is installed and where the plant room sits. The site visit and the quote are both free.
Which areas do you cover? All of Greater Cairo, east, west and south. Ain Sokhna, the North Coast, the Delta and Upper Egypt follow a site visit.
Tell us the volume and we will match the plant to it
Send the length, width and depth, the pool type and a photo of the plant room. After the site visit you get a written specification and a price from our rate book. If you say no, you owe us nothing.
