Determining The Sustainable Economic Level of Physical Losses in Drinking Water Networks: Case of Merzifon
Öz
The sustainable economic level was investigated in reducing physical water losses in drinking water networks in this study. All possible strategies follow the principle of diminishing efficiency to reduce physical water losses in drinking water networks. The incremental return decreases in terms of water saved as the expenditure increases on water loss reduction in the principle of diminishing efficiency. Water utilities need to estimate the economic level of water losses so that they can reduce water losses to the level where the cost of reducing water losses equals the value of water saved. In the case of Merzifon, it has been determined that the sustainable level of leakage is 4,5 % in the case of taking the loss and leakage measures based on the physical water loss and leakage amount of 2020 in the water network. Determining the cost of water is important in determining the level of sustainable economic loss and leakage in a water service supply region. It is important to consider the situation of water withdrawal above the regeneration rate of the water from the source and the resource cost incurred by the activities carried out for the protection of water resources on a basin basis in determining the value of water.

İçme Suyu Şebekelerinde Fiziki Kayıpların Sürdürülebilir Ekonomik Seviyesinin Belirlenmesi: Merzifon Örneği
Öz
Bu çalışmada içme suyu şebekelerinde meydana gelen fiziki kayıplarının azaltılmasında sürdürülebilir ekonomik seviye araştırılmıştır. İçme suyu şebekelerinde fiziki kayıpları azaltmak için olası tüm stratejiler azalan verim prensibini takip etmektedir. Azalan verim prensibinde, fiziki kaybının azaltılmasına yapılan harcama ne kadar yüksekse, tasarruf edilen su açısından kademeli getiri o kadar düşük olur. Su idarelerinin fiziki kayıplarını, azaltma maliyetini tasarruf edilen suyun değerine eşit olduğu seviyeye indirebilmeleri için, fiziki kayıplarının ekonomik seviyesini tahmin etmeleri gerekmektedir. Merzifon örneğinde 2020 yılına ait fiziki kayıp miktarı esas alınarak su şebekesinde fiziki kayıpların önlenmesi durumunda sürdürülebilir fiziki kayıp seviyesinin %4,5 olduğu tespit edilmiştir. Bir su hizmeti sağlama bölgesinde suyun maliyetinin belirlenmesi sürdürülebilir ekonomik fiziki kayıp seviyesinin belirlenmesinde önemlidir. Suyun maliyetinin tespitinde suyun kaynağından yenilenme oranı üzerinde su çekilmesi durumu ve havza bazında su kaynaklarının korunması için yapılan faaliyetlerle oluşan kaynak maliyetinin göz önünde bulundurulması önem arz etmektedir.
