The utilization of pipelines in water supply endeavors has consistently held significant and promising implications. The employment of enclosed conduits for the conveyance of fluids has been particularly crucial in terms of passive defense mechanisms and the preservation of drinking water cleanliness. This research article aims to present a concise comparative analysis between steel pipes and pseudo-steel GRP for water conveyance within the context of the Darab water supply project, delineating the respective merits and advantages of each material and examining the influence of the pipe type on the financial model, culminating in an evaluation of water cost. The rationale behind selecting the Darab water supply initiative originating from the Rudbal Dam stems from the challenging location of the project and its critical significance in addressing water scarcity issues in the arid expanse of Fars province. It is imperative to highlight that within this framework, the latent expenses associated with water supply projects under the Build-Operate-Transfer (BOT) contract methodology have been deliberated upon, with the ultimate projection of the overall project cost factoring in updated construction and operational expenses over a defined timeframe
