Various parameters must be considered when designing a buried piping system. Two of the main considerations should be the pipe properties and the soil envelope around the pipe. To the layman, the word “soil” can mean different things. To engineers involved in pipe burial, soil is any earthen material excluding bedrock.Soil has been used as a construction material throughout history. Soil is important not only as a material upon which the structure rests, but also for support and load transfer. The soil envelope transfers surface and gravity loads to, from, and around the structure.

This paper addresses the inaccurate hydraulic claims made by the Ductile Iron Pipe Research Association (DIPRA) and shows that when industry-accepted data are used, PVC pipe is more energy efficient, cost effective, and sustainable than ductile iron (DI) pipe. DIPRA maintains that DI pipe has lower pumping costs than PVC pipe. The claim is that DI’s larger inside diameters (ID) offset PVC’s better flow characteristics. However, DIPRA’s brochures and on-line calculator contain misleading information and erroneous hydraulic assumptions, generating biased results.

Dribbling is a very common and usual trait of the water that almost every owner of pond or reservoir or farmer faces. We have formally named this dribbling “Seepage”. You can spot your pond or reservoir water also in normal time and especially after a heavy shower to leak through by a narrow channel from one place to another. Generally it happens due to ground water level rising in soil that creates hydrostatic pressure. Whenever you spot seepage you should take action to stop it immediately or it can be really harmful for your aquaculture. So, to stop this seepage and maintain the clean water level and quality at your storage you need to put a barrier in the water and those channels. In one word the solution of the seepage is Pond Lining Films or Pond liners.
