The Pipp Brook is a left-bank tributary of the River Mole, Surrey, England. It rises at two main springs north of Leith Hill on the Greensand Ridge, then descends steeply in a northward direction, before flowing eastwards along the Vale of Holmesdale. It runs to the north of Dorking High Street, before discharging into the Mole at Pixham.
The Milton Brook, which rises at a tri-forked source lower than that of the Pipp Brook, is the principal tributary.
The geological varying depth of greensand top layers caused by erosion towards the underlying clay means that there is no uniform spring line in this part of the Greensand Ridge. The tower is the second highest point in the South-East of England. [2] The Pipp Brook's main tributary, the Milton Brook rises at three close points in farmland on the indented north-east edge of the forest.
During the early nineteenth century the sulphate-rich (chalybeate) waters of the Mag's Well spring were attributed by a countryside travel writer as having aided a person's recovery. [3]
Both the Pipp Brook and the larger River Tillingbourne drain the northern slopes of Leith Hill and the watershed between the two rivers (which runs roughly north–south, marks the boundary between Westcott (which the brook drains entirely) and much larger Wotton. [4] [5] [note 1]
The Pipp Brook runs almost due east along its Dorking stretch north of much of the town and south of the steep scarp of the North Downs at Ranmore Common before joining the Mole at Pixham. [note 2] The area around the confluence is the subject of occasional riparian (river) flooding as the rate of descent of the Mole decreases significantly and at the Mole Gap becomes or became subterranean, depending on amount of sedimentation. [6]
The Pipp Brook itself has no sewage treatment works, few plains which it drains and as such an extremely narrow and low risk area of riparian flooding. [6] These factors are instead present as to a few parcels of land of east Pixham sometimes considered Dorking by the national media based on a 2010s shorthand by the Environment Agency which has a 'Dorking Flood Area' comprising the sewage works, a handful of properties in Pixham and much of Brockham and Betchworth well upstream along the Mole to the east which are separated by more than a mile from Dorking and are narrowly in its post town. [6] [7]
By the 19th century six grain mills stood on the river: Rookery, Westcott, Milton Court, Parsonage, Pippbrook and Pixham Mills. [8] All were defunct by the mid-20th century when bread production was widely commercialised and the product nationally was transformed to slow its staleness. Pippbrook Mill and Pixham Mill survive and are Grade II listed buildings. [9] [10]
The Environment Agency measures the water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations, is rated good or fail. [11]

Dorking is a market town in Surrey in South East England about 21 mi (34 km) south of London. It is in Mole Valley District and the council headquarters are to the east of the centre.

Westcott is a village in central Surrey, England, about 1.5 miles (2.5 km) west of the centre of Dorking. It is in the Mole Valley district and the Surrey Hills Area of Outstanding Natural Beauty. The Pipp Brook, a tributary of the River Mole, runs to the north of the centre and the settlement is between Ranmore Common on the North Downs and Leith Hill on the Greensand Ridge.
The Greensand Way is a long-distance path of 108 miles (174 km) in southeast England, from Haslemere in Surrey to Hamstreet in Kent. It follows the Greensand Ridge along the Surrey Hills and Chart Hills. The route is mostly rural, passing through woods, and alongside fruit orchards and hop farms in Kent and links with the Stour Valley Walk near Pluckley in Kent. The trail was opened on 15 June 1980 and is jointly managed by Surrey and Kent Councils who fully updated it in 2012.
Betchworth is a village and civil parish in the Mole Valley district of Surrey, England.

The River Tillingbourne runs along the south side of the North Downs and joins the River Wey at Guildford. Its source is a mile south of Tilling Springs to the north of Leith Hill at grid reference TQ143437 and it runs through Friday Street, Abinger Hammer, Gomshall, Shere, Albury, Chilworth and Shalford. The source is a semi-natural uninhabited area. The catchment is situated on sandstone which has a low rate of weathering. The Tillingbourne is 24 km (15 mi) in length.
Wotton is a well-wooded parish with one main settlement, a small village mostly south of the A25 between Guildford in the west and Dorking in the east. The nearest village with a small number of shops is Westcott. Wotton lies in a narrow valley, collecting the headwaters of the Tilling Bourne which then has its first combined flow in the Vale of Holmesdale. The parish is long north to south, reaching to the North Downs escarpment in the north to the escarpment of the Greensand Ridge at Leith Hill in the south.
Betchworth Castle is a mostly crumbled ruin of a fortified medieval stone house with some tall, two-storey corners strengthened in the 18th century, in the north of the semi-rural parish of Brockham.

Holmesdale, also known as the Vale of Holmesdale, is a valley in South-East England that falls between the hill ranges of the North Downs and the Greensand Ridge of the Weald, in the counties of Kent and Surrey. It stretches from Folkestone on the Kent coast, through Ashford, Harrietsham, Maidstone, Riverhead/Sevenoaks, Westerham, Oxted, Godstone, Redhill, Reigate, Dorking, Gomshall, and Guildford – west of which it is also called by the local name of "Puttenham Vale" – as it continues through the village of Puttenham, to the market town of Farnham.
The River Wey is a main tributary of the River Thames in south east England. Its two branches, one of which rises near Alton in Hampshire and the other in West Sussex to the south of Haslemere, join at Tilford in Surrey. Once combined, the flow is eastwards then northwards via Godalming and Guildford to meet the Thames at Weybridge. Downstream the river forms the backdrop to Newark Priory and Brooklands. The Wey and Godalming Navigations were built in the 17th and 18th centuries, to create a navigable route from Godalming to the Thames.
