With a focus on designing and manufacturing water and wastewater treatment equipment, Poly Payesh delivers a solution tailored to the real conditions of every project. By reviewing the type of water or wastewater, the flow rate, the installation space, and the expected output quality, we design a system whose performance, durability, and operating cost are aligned with the project's needs — from wastewater treatment packages and RO units to pumping stations, septic tanks, grease traps, and polyethylene tanks and pipes.
