Groundwater
The Pillhill Brook Association (PBA) monitors groundwater behaviour within our catchment on a weekly basis. Groundwater level is important because it dictates the height of water in the brook and hence flow and also how quickly rainfall will soak away into the ground, preventing flooding. We monitor levels at 5 local boreholes:
Clanville Gate in Clanville
High View in Kimpton
Stanbury Road Water Pumping Station (WPS) in Kimpton
Haydown Farm in East Cholderton
Monxton WPS in Monxton
See map below for locations.
