Cyprus’ Statistics

  • Annual rainfall460 mm

  • Capacity of dams300 million m3

  • Water demand per year270 million m3

  • Water demand for

    agriculture70%


Total Effluent Production

Now

  • 5urban WWTP operate

  • 14,6 million m3 tertiary treated effluent

    produced yearly

  • 8 % of water demand for agriculture

    By2020

  • 7WWTP will operate

  • 42 million m3 tertiary treated effluent will be produced yearly

  • 23 % of water demand in agriculture


Quality Characteristics

Tertiary Treated Effluent


Reuse

+

Agricultural production

Increase green areas

Golf course irrigation

Avoid sea pollution

_

Storage Reservoirs

Distribution costs

Health risks

Discharge

+

No investment in reservoirs and distribution networks

_

Loss of natural and financial wealth

Sea pollution

Reuse Vs Discharge


Encouragement for re-use

Pricing policy


Limassol WWTP


Limassol Reuse/Discharge Scheme 2004

  • 25 km transfer main from the east to the west side of Limassol

  • 2004 production = 6,5 million m3

  • 85% - irrigation of citrus plantations and fodder crops

  • 15% - sea discharge


Larnaca WWTP


35 km irrigation mains operating under 9 atm pressure recycling 100% of effluent produced - 1,50 million m3

1,10 million m3 (73%) for fodder crops

(clover and corn)

0,25 million m3 (17%) for football grounds

0,15 million m3 (10%) for hotel and municipal gardens

Larnaca Re-use scheme 2004


Irrigated Corn Fields


Irrigation with recycled water
