Abstract: A grouting well pipe for a water well. The grouting well pipe has a central well pipe with at least one grouting tube attached along its length. The grouting tube is sealed along its lower end and length to prevent clogging of the grout tube during insertion of the grouting well pipe into a water well. The grouting tube has a grout release structure thereon for release of grout into the space between the grouting well pipe and the water well in response to pumping grout at a predetermined pressure into the grout tube. This seals the space effectively from surface contamination entering the well.
