PVC well materials

The exact installation depth generally depends on the installation and operating conditions. As a rough rule of thumb, the K series can be installed to a depth of 100 m, the KV series to 200 m, and the KVV series to 300 m. In most cases, the installation depth is limited by the pipes' external pressure resistance; this value can be found in the GWE catalog based on pipe size and wall thickness. The actual external pressure acting on the well casing depends on various factors, such as the groundwater level below ground level (GL) or the method used to place the filter gravel. If you have questions regarding specific design specifications, GWE’s contacts for well construction materials will be happy to assist you.

No, our PVC-U well casing material does not contain toxic substances such as lead or specific phthalates with endocrine-disrupting effects. Our PVC pipes for drinking water wells are approved for contact with drinking water (KTW certification); to maintain this, our pipes undergo annual testing by an independent testing institute.

GWE uses high-quality PVC-U designed for a long service life in well construction. The design of the pipes and threaded connections is based on permissible equivalent stresses intended to ensure a service life spanning several decades. Material properties, dimensions, and tolerances are monitored through continuous quality checks during production and prior to shipment to ensure consistently high product quality.
