Drainage Services in Farnham

Farnham's well-preserved Georgian and older town centre sits on Lower Greensand, a generally free-draining sandy geology that historically supported the area's hop-growing industry. This helps natural drainage in many parts of town, though the underlying sand can still allow fine material to wash into older pipe runs where joints have failed. The town centre's historic buildings typically retain older clay drainage, often as part of combined sewer systems, while later development towards Weybourne and Badshot Lea uses more modern clay and plastic pipework.

The River Wey passes close to Farnham, and low-lying land near the river and in areas such as Tilford can have a higher water table, particularly after wet winters, which affects how quickly surface water disperses. Farnham's many mature gardens and tree-lined streets, a legacy of its long history as a market town, mean root ingress into older clay joints is a regular occurrence, especially in the historic core. Rural properties around Rowledge and Tilford on the town's edges often remain on septic tanks or small package treatment plants.

Our approach for Farnham starts with a CCTV survey to accurately trace any blockage or defect along the drain run, particularly important in the historic town centre where original pipe routes are not always documented. High-pressure jetting is effective at clearing sand and silt build-up typical of the local greensand geology, and no-dig lining lets us repair cracked or root-affected pipework without disturbing period properties or established gardens. For rural households near Rowledge or Tilford using septic tanks, we offer percolation testing to confirm the drainage field remains effective.
