Water and drainage Water supply Masterton's water is piped from the
Waingawa through a Masterton District Council treatment plant on the river, about 10 kilometres west of the town. The water is clarified and filtered, then chlorinated and fluoridated. Lime is added to neutralise the pH to protect the pipes. There is a fluoride-free drinking water tap in Manuka Reserve in Manuka Street. Typhoid epidemics broke out each year in Masterton and in 1896 Parliament approved a Borough Council loan to build a drainage and water supply system. Work on the water supply did not begin until 1899 delayed by disagreements over the appropriate sources for water. It was finished at the end of 1900 when at the formal opening ceremony there was enough pressure to send a jet right over the Post Office tower to the accompaniment of the Masterton Municipal Brass Band. The mayor, Mr Pownall, said he was now ready to pour cold water on the scheme's opponents. A covered reservoir and treatment plant at Fernridge was supplied by an intake from springs beside the Waingawa four miles further up river. The main was duplicated in 1915. It was replaced by the current system, completed in 1983.
Wastewater A sewage system was completed in 1901. It drained through settlement ponds and filter beds to the
Ruamāhanga River south of the town. The sewage farm's system included a newfangled "
septic tank" which was subject to failures. In 2012, after a period of heavy rain, eels were found in a Masterton street. In 2013, when the existing treatment pond at the
Homebush wastewater treatment plant was being replaced with a new pond, the council had to relocate an estimated 85,000 eels that were living in the old pond. Around half of the eels (about 20 tonnes), were rescued by the
iwi Ngati Kahungunu for relocation into other Wairarapa lakes and streams. In March 2022, following periods of heavy rain, high levels of groundwater infiltration into the sewage network led to the emergency discharge of treated sewage into the Ruamāhanga River from the Homebush wastewater treatment plant for a period of one week. In April 2023, the council was strongly criticised for continuing incidents of overflow of raw sewage into properties in Cockburn Street during periods of heavy rain, a recurring problem that dates from 2006.
Energy The Wairarapa Electric Power Board was
established in Carterton in 1920 to supply the Wairarapa with electricity from the
Kourarau hydropower station at Gladstone, southeast of both towns. Masterton was connected to
Mangahao on 17 May 1925 when the transmission line from
Bunnythorpe to Masterton (via Woodville and Mangamaire) and the Masterton substation were commissioned. The Wairarapa Electric Power Board moved to headquarters in Masterton in the 1950s. The power board, then named Wairarapa Electricity, dissolved following the 1998 electricity sector reforms. The retail business was sold to
Genesis Energy and the distribution lines business sold to
Powerco. Today Powerco continues to operate the local distribution network in the town and surrounding district with electricity fed from
Transpower's national grid at its Masterton substation in Waingawa. Masterton Gas Company was established by the Borough Council in 1886 by the corner of Bannister and Kirton Streets. About 20 years later it was moved to the end of Bentley Street, just south of the railway station. The large quantities of coal were brought in by rail. By 1945 it had become clear consumers preferred electricity and the gasworks closed in the 1950s. There is no
natural gas network in Masterton, making it the largest North Island urban area without one. There has been no more than a proposal to connect Masterton to the North Island natural gas network via a branch off the Palmerston North to Hastings high-pressure pipeline, commissioned in 1983.
Telephone The Masterton
magneto telephone exchange opened on 31 January 1897, with 53 subscribers. On 31 May 1919, Masterton became the first town in New Zealand to have a fully automatic (Western Electric 7A
Rotary) telephone exchange. Masterton and nearby
Carterton were the first towns in New Zealand to introduce the
emergency number 111, in September 1958.
Internet On 3 December 2015 the
UFB rollout to the town was completed. ==Transport==
