威斯康星州的一家自来水公司实施了一个示范项目，使用水平定向钻井设备直接在经历了严重外部点蚀的现有自来水总管旁边安装连续线性阳极。初步示范项目的结果表明，水管的寿命延长40年是可以实现的，但成本远远低于管道的更换成本。
A Wisconsin water utility has implemented a demonstration project using horizontal directional drilling equipment to install a continuous linear anode directly alongside an existing water main that has experienced significant external pitting corrosion. The results of the initial demonstration project suggest that a 40-year life extension of the water main may be achievable at a cost that is significantly less than the replacement cost of the pipe.
