This plant has been constructed by the Water DevelopmentDepartment and treats waste which is transferred by tankers from thedistricts of Nicosia and Larnaca (areas which are not connected yetwith sewer systembut they use septic tanks).It also treats five types of industrial waste, transferred also by tankerssuch as:

§dairy washings, §fat oil and grease, §washings from metals, §strong organic waste and §weak organic waste.

It also treats the surplus activated sludge from small wastewatertreatment plants.

The policy of the Government is that the treatedeffluent produced by the Urban SewerageBoards will be handled and disposed by theGovernment. For this reason the WaterDevelopment Department is responsible for thesupply of treated effluent from the urbanwastewater treatment plants.

The cost for the construction and the operationand maintenance of the tertiary treatment plantcarried out by the Urban Sewerage Boards isundertakenby the Government.

15

IN CYPRUS THE TREATED EFFLUENT FROM THE URBAN WASTEWATER TREATMENT PLANTS IS REUSED FOR THE FOLLOWING PURPOSES :

• IRRIGATION• ENRICHMENT OF UNDERGROUND WATER (PAPHOS WASTEWATER TREATMENT PLANT)

THE IRRIGATION IS DONE UNDER THE CODE OF CORRECT AGRICULTURAL PRACTICE.

OTHER WAYS OF DISPOSAL

•DISCHARGE INTO THE SEA

DURING WINTER MONTHS IN LARNACA AND LIMASSOL WHENTHERE WAS NO DEMAND FOR IRRIGATION SOME QUANTITIES ARE DISCHARGED INTO THE SEA (as described in the Discharge Permit)

According to the Laws of the Water Pollution Control of 2002 until 2007,for the big municipal wastewater treatment plants the Minister Of Agriculture is issuing a Wastewater Discharge Permit for the same Wastewater treatment Plant to the following competent authorities:

• Sewerage Boards• Water Development Department

In the Discharge Permit the following are defined:

• quality characteristics.• number and the type of analyses • disposal of the treated effluent

For the Discharge Permit of the Water Development Department the following are included:

•Name of Authority : Water Development Department•Type of Process: Disposal of Treated Effluent•Type of Discharge:Treated effluent from the wastewater treatment plant

QUALITY CHARACTERISTICS AND CONTROL OF THE TREATED EFFLUENT FOR AGGLOMERATIONS ABOVE 2000P.E. ACCORDING

TO THE DISCHARGE PERMITS

34

Ø The Water Development Department and the Sewerage Boards are also following the quality of the treated effluent according to the requirements of their Discharge Permits.

Ø The quality characteristics and the frequency of analyses of the treated effluent which are included in the discharge for the wastewater treatment plants are presented in the following tables.

Ø Discharge permits for quality and control for urban wastewater treatment plants frequency of analyses and maximum limits for WWTP for communities with above 2000 P.E.

The treated effluent is another constant source of water.

The Government's policy is to introduce the treated effluent in the Cyprus Water Balance.

The Quality is under control and remains constant.

The treated effluent is suitable for the majority of the crops.

Almost all the Wastewater Treatment Plants are equipped with Tertiary Treatment , consisting of Sand Filtration and Chlorination in order to achieve higher quality characteristics in order to use the treated effluent in the Agriculture.

The farmers use less quantities of fertilisers because the treated effluent contains already nutrients such as Phosphorous and Nitrogen.
