CONTROL OF THE GROUND WATER LEVEL BY INFILTRATION VIA A TUNNEL

KONTROLL AV GRUNDVATTENNIVAAN GENOM INFILTRATION VIA TUNNEL

The object of this research report is to test in practice and to evaluate a method for the control and regulation of the groundwater level in a built-up area. From a recharge well at ground level, water is taken through a rock tunnel, through boreholes, into the fissure system and through the top of the rock into the soil. The full-scale test has been successful. In the valley concerned the groundwater level rose to the desired level after two days and remained at this level afterwards. The method is considered cheaper and uses less energy than soil reinforcement measures for an accepted drop in groundwater level. Planning of tunnels and infiltration tunnels should start at an early stage, preferably in conjunction with regional planning. The problems are often of an intermunicipal nature. Different municipal administrations employ different standards concerning groundwater, and it would therefore be desirable for the county administrations to employ geotechnical engineers in order that the overall economy of these problems may be assessed. /TRRL/
