Education

Waterloo School is a co-educational state primary school for Year 1 to 6 students,[10][11] with a roll of 524 as of October 2025.[12] It opened in 1938.[13]

The Open Polytechnic of New Zealand is in Waterloo.[14]

Waiwhetū Stream

The Waiwhetū Stream is a small watercourse that flows through Waterloo and drains the eastern side of the Hutt Valley. It enters Wellington Harbour at the Hutt River estuary. Development and urbanisation of the Hutt Valley since the arrival of settlers led to increasing pollution and degradation of the stream environment. The stream was diverted into concrete culverts in many sections in an attempt to reduce flooding. Industrial development in the area around the lower reaches of the stream led to that section becoming an industrial sewer. In 2010, the stream was described as one of the most polluted waterways in New Zealand.[15]

Pressure from the community beginning around 2003 helped to trigger a major project to clean up the lower reaches. This project was declared complete in June 2010, after the removal of 56,000 tonnes of toxic waste. In 2010-11, a community group was formed to lead restoration of the upper reaches of the stream. Over a period of 10 years, volunteers cleared invasive aquatic weeds and rubbish from 6 kilometres (3.7 mi) of the stream bed and established around 34,000 locally sourced native plants on the banks of the stream.[16]

Infrastructure

Railway station

Waterloo railway station (previously known as Waterloo Interchange or Hutt Central) is a dual-platform suburban railway station serving the suburbs of Waterloo, Lower Hutt Central and Woburn. The station is on the Hutt Valley section of the Wairarapa Line, 15.5 km (9.6 mi) north of Wellington. Waterloo serves as a major bus-rail interchange, connecting buses to and from central Lower Hutt, Naenae and Wainuiomata with trains to and from Wellington.[17]

Water treatment plant

A large water treatment plant is located alongside the Waterloo Railway Station. The water treatment plant is a significant part of the water supply in the Wellington Region, and draws water from the Waiwhetu aquifer via a bore field of eight wells.[18]
