The '''Jaison Water Tap''' or '''Jayson Water Tap''' (also known as '''Waste Not Water Tap''') is a self-closing water-saving tap<ref name="book_1978_nepal_pipe_fitting"/> invented in the early 20th century

by [[J.P. Subramonya Iyer]] at [[Travancore]], South India.
These taps were a common sight on the roads in erstwhile [[Travancore]], part of modern-day [[Kerala]] state in South [[India]].
They are quite popular throughout the Indian sub-continent and can still be commonly found in most of the traditional railway stations operated by [[Indian Railways]].

== History ==
J.P. Subramonya Iyer, who invented the tap, served as an insurance officer in the erstwhile [[Travancore-Cochin]] state.<ref name=achuth_13Jan2017/> The tap was meant to reduce the water wastage which occurred when road-side water taps were left open by their users. With the help of a few friends who were engineers, such as [[Sri Rajangam]] (Deputy Chief Mechanical Engineer of [[South Indian Railway Company|South Indian Railway]]) and S.L.Narayanan, he developed the tap.<ref name="sri_rajangam_biography">{{Cite web|url=http://ravanasamudram.com/know-your-past-generation/|title=Ravanasamudram: Know Your Past Generation - Sri Rajangam|website=ravanasamudram.com|language=en-US|access-date=2017-12-13}}</ref>
He patented the invention, improved it further and patented the improved tap version as well. The Jaison water tap was the first of its kind to be patented.

In order to facilitate large-scale production, Subramonya Iyer set up a factory at [[Karamana]]. Due to militant trade union activism prevalent in the region, the factory had to shut shop and moved to [[Coimbatore]].<ref name=achuth_13Jan2017/>

== International use ==
The Jayson Tap has been used in many countries such as [[Nepal]],<ref name="book_1978_nepal_pipe_fitting">{{Cite book|url=https://archive.org/details/fa_Rural_Water_Supply_in_Nepal-Pipe_and_Fitting_Course|title=Technical Training Manual No. 4, Pipe and Fitting Course, Rural Water Supply in Nepal|publisher=Local Development Department, Ministry of Home and Panchayat, SATA - Series Association for Technical Assistance, UNICEF|year=1978}}</ref> [[Sri Lanka]]<ref name="paper_1984_sri_lanka">{{Cite web|url=https://www.ircwash.org/resources/public-standposts-colombo-sri-lanka|title=Public Standposts in Colombo, Sri lanka: A Support Paper by Bep.

[[HydroPlan]], a German company, purchased the rights to produce, sell and distribute the tap worldwide except in India and Sri Lanka. Subsequently, the tap spread to [[Europe]], [[England]] and [[Japan]].<ref name=achuth_13Jan2017/>

== Current deployments ==
Ironically, usage of the tap in its birthplace, Kerala, has steeply declined in the 21st century. Public water taps on roads face extinction in Kerala, due to increased usage of bottled water by the state's relatively affluent population.

[[Indian Railways]] still uses the Jaison water tap widely across India,<ref name="madras_musings_jul_2006">{{Cite news|url=http://madrasmusings.com/older-archives/Vol%201/Vol%20I%20-%20No%2006.pdf|title="Foods and Fads: Hope for the head"|last=K|first=V|date=July 1–14, 2006|work=[[Madras Musings]], Vol.1, No.6, Page 6|access-date=2018-01-14|archive-url=https://web.archive.org/web/20180114111139/http://madrasmusings.com/older-archives/Vol%201/Vol%20I%20-%20No%2006.pdf|archive-date=2018-01-14}}</ref> both inside trains and at stations. Both metal-based and plastic-based variants are in use.
