The connection to the water supply network is made by constructing the branch and installing the Metering device.
The branch includes the required distributor (collector). The installation of the Metering device includes all necessary materials (water meter, isolation valve, check valve, etc.).
WATER SUPPLY CONNECTION COST = Branch Cost (A) + Water Supply Connection Fee (B)
WATER SUPPLY CONNECTION FEE (B) = Metering Device Cost + Metering Device Usage Guarantee
A. BRANCH CONNECTION COST CALCULATION
- WITHIN THE PLAN AREA
CONNECTION COST = ½ of the average street width × average branch cost per running meter.
Average street width = The average distance between the planning lines of the building blocks (O.T.), rounded up to the nearest whole number.
- OUTSIDE THE PLAN AREA and in PLAZAS WITHIN THE PLAN AREA
CONNECTION COST = Actual branch length × average branch cost per running meter.
- Average branch cost per running meter (The cost depends on the diameter of the supply pipe)
B. WATER SUPPLY CONNECTION FEE CALCULATION
CONNECTION FEE = Metering Device Usage Guarantee + Metering Device Cost
- Metering Device Usage Guarantee (The price depends on the property’s use)
- Metering Device Cost (The price depends on the diameter of the water meter)
- INSTALLATION OF METERING DEVICE
The installation of the Metering device includes all necessary materials (water meter, isolation valve, check valve, etc.).
CONNECTION FEE = Metering Device Usage Guarantee + Metering Device Cost
- Metering Device Usage Guarantee (The price depends on the property’s use)
- Metering Device Cost (The price depends on the diameter of the water meter)
In cases of replacing the Metering device or individual components, the payment of the Usage Guarantee is not required.
NOTE: The amounts corresponding to the above costs are determined in DEYAR’s pricing policy.
The connection to the sewerage network is made by constructing the branch and the property disposal point.
SEWERAGE NETWORK CONNECTION COST = Branch Cost (A) + Connection Fee/Right (B)
A. BRANCH COST CALCULATION
- WITHIN THE CITY PLAN
BRANCH COST = ½ of the average street width × average branch cost per running meter.
Average street width = The average distance between the planning lines of the building blocks (O.T.), rounded up to the nearest whole number.
- OUTSIDE THE CITY PLAN and in SQUARES WITHIN THE CITY PLAN or UNDEVELOPED STREETS
BRANCH COST = Actual branch length × average branch cost per running meter.
Β. SEWER CONNECTION FEE CALCULATION
CONNECTION FEE = Measured area (m2) x Average Property Value (€)
- Measured Property Area
The measured area includes all built-up areas of the property across all floors, regardless of their use or whether they are supplied with water, such as basements, attics, or open verandas within rooms, etc. It does not include ground-level open areas supported by columns (garage), according to the building code, or open terraces.
The Sewerage Network Regulation defines the measured areas and any exceptions.
- Average Property Value
The average contract price per m² of the property for calculating the connection fee is determined according to property categories based on their use as follows:
| Category | Use |
| A | Residences – offices – shops – warehouses |
| B | Hotel accommodations |
| C | Small industrial and workshop buildings |
| D | Public and municipal educational institutions |
| E | Public and municipal health institutions |
| F | Municipal properties (excluding educational or healthcare institutions), sports facilities |
