Septic tank dimensions may vary depending on the volume of the desired product. These dimensions are determined according to your location or project situation and production is provided in the most appropriate size. The most important issue regarding septic tank dimensions is to ensure minimum excavation and ease of installation. At the same time, the minimum amount of material to be poured onto the tank is ensured. We make septic production in certain standard sizes based on our demands and experience. However, in line with the demands from you, production is provided in alternative sizes.
