We stock 1″ and 2″ well pipe (though we can special order other sizes if required). 2″ pipe is the most common and is generally industry standard for environmental monitoring wells, while 1″ is common for geotechnical piezometers. As most of our installations are using our 4″solid stem augers, we usually will use the 2″ pipe, which is suitable for conventional Waterra tubing and valves, bailers, and water level or interface meters. We also use this pipe for installations using hollow stem augers.
For wells installed with the rapid percussion units (Pionjar, Rota-Hammer, PEP) we are boring a 2″ hole and therefore we use 1″ well pipe. With our small diameter hollow stem augers, we can use a 1″ or 2″ well pipe. Though the 1″ pipe is small, a conventional water level or interface meter will fit in the pipe. We can also supply a small diameter bailer or a small diameter waterra foot valve for well sampling.
