What it is
The EYDAP tariff in force from 1/1/2026 (Regulatory Authority decision Υ-86/2025) has a special discount for families with three or more dependent children.
What you get:
- Water is charged at the first band, €0.35 per m³, as long as monthly consumption does not exceed 20 m³ for a five-member family or 16 m³ for a four-member single-parent family. For larger families the limit rises by 4 m³ for each child beyond the third.
- If you go over the limit, the consumption above it is charged at the general tariff, starting from the second band.
- You pay no fixed water and sewerage charge.
Conditions: lawful, permanent residence in the area EYDAP supplies. Large-family status is proven with the documents the law requires and is checked again every year. The discount also applies to off-network customers whom EYDAP charges for sewerage use.
Anyone who also qualifies for another EYDAP special tariff (large families, older people, the Special Emergency Tariff) chooses the most favourable one and keeps it for one year.
