QUICK ANSWER01
First identify the water. Then calculate the home.
A brackish borehole leads to DESAL-BWRO. A seawater intake leads to DESAL-SWRO. Within that route, daily volume, operating hours and usable storage define the required production rate.
SOURCE-WATER DECISION
The same villa can require a completely different RO platform.
Location does not define the technology. The measured feed water does.

Do not select from conductivity alone.
Hardness, alkalinity, iron, manganese, silica, turbidity or SDI, organics, temperature and seasonal variation determine pretreatment, recovery and membrane duty.

STEADY PRODUCTION · STORED RESERVETHE STORAGE PRINCIPLE
The RO system does not need to follow every tap opening.
A product-water tank supplies short peak demand while the treatment system produces at a stable rate. This allows a smaller, more controlled plant and an operating schedule selected around noise, power availability and source conditions.
SourceBrackish or seawaterDESAL systemSteady productionStoragePeak-demand bufferHomeOn-demand supply
Tank sizing, turnover, materials, venting, level control, post-treatment and disinfection are confirmed for the project.
RESIDENTIAL ENGINEERING CHECK
Six interfaces define a dependable private supply.
Capacity is only one part of the installation.
Source-water analysis
Conductivity alone is not enough. Check hardness, alkalinity, iron, manganese, silica, turbidity or SDI and source variability.
Daily demand
Separate normal occupancy from guest peaks, pool top-up, irrigation and cleaning so the plant is not sized from an unrealistic average.
Storage & runtime
A correctly sized product-water tank decouples household peak flow from the RO production rate and allows quieter operating windows.
Utilities
Confirm available electrical supply, protection, drainage, feed pressure and any need for backup operation before fixing the model.
Plant-room access
Allow ventilation, dry service space, filter replacement, membrane access and safe chemical handling—not only cabinet dimensions.
Product-water duty
Drinking, general household use, irrigation or equipment feed can require different post-treatment, storage and disinfection.
DESIGN FOR REAL OCCUPANCY
Normal days, guest peaks and seasonal use are different duties.
A summer villa may combine maximum occupancy, showers, laundry, pool top-up, landscape irrigation and the warmest source-water condition at the same time.

VILLA & HOME FAQ
Answers that improve the selection.
01Should a villa system be selected from the number of bedrooms?
Bedrooms provide an occupancy clue but not a complete demand. Use expected people, actual daily consumption, guest peaks, laundry, pool top-up, irrigation and cleaning. Divide the resulting daily volume by realistic operating hours and then review reserve and storage.
02How do I know whether the source is brackish water or seawater?
Use current measured conductivity and a laboratory analysis. Do not choose from taste, location or a generic TDS conversion. Coastal wells can also change seasonally, so the highest credible source condition must be considered.
03When do I choose DESAL-BWRO Q instead of XP?
Both are compact brackish-water platforms. Q covers 50–125 L/h and catalog configurations up to 10,000 µS/cm; XP covers 22.5–125 L/h and extends to 15,500 µS/cm, including LR permeate-quality configurations. The exact choice follows the analysis, output and required product-water quality.
04Why is a product-water storage tank important?
The tank supplies short household peaks while the RO system produces at a steady rate. It can reduce unnecessary starts, support a preferred operating schedule and provide a practical reserve during maintenance or source interruptions.
05Can one system supply drinking water, showers, pool and irrigation?
It can be engineered for several uses, but each demand and quality target must be stated. Potable use may require remineralisation and disinfection, while irrigation and pool top-up can materially increase daily volume. Distribution and storage hygiene also require review.
