- 9,427m of pipes
- 254 manholes
- 1,555m of open channel
- 2 storage / retention ponds

There are four main catchments in Edgecumbe delineated by the Rangitaiki River running south to north through the township and the railway embankment running east-west. Edgecumbe southwest and northwest are on the west of the Rangitaiki River. Edgecumbe southeast (Konini Place and Hydro Rd area) is on the east bank. Edgecumbe northeast is occupied by the Fonterra Dairy factory and the EastPack kiwifruit packhouse and cool store.
