Water Filtration System Layout for a House with Storage Tank, Water Softener, and Ultrafiltration, with a Separate Drinking Water Line

In this system, water enters from the municipal supply and passes through an inlet service valve, which allows the water to be shut off during maintenance.
Next, the water flows through a PP sediment filter. This stage removes sand, rust, and suspended particles, preventing contamination of the storage tank.
After that, water is directed into a rooftop storage tank, creating a reserve supply for the household.
From the tank, water is delivered into the plumbing system and passes through a water softener. The softener removes calcium and magnesium hardness salts, making the water soft and protecting the boiler, plumbing, and household appliances from scale buildup.
The next stage is ultrafiltration with automatic backwash. Ultrafiltration removes bacteria and fine particles, providing an additional safety barrier in case contamination occurs in the storage tank.
After treatment, water is supplied to:

• the cold water system of the house
• the boiler for hot water preparation

In parallel, a separate raw water line is taken directly from the main inlet to the kitchen. A service valve and a reverse osmosis system are installed on this line.
The reverse osmosis system provides deep purification of water for drinking and cooking.
