The Nilavarai Well is popular attraction in Jaffna lying in Puttur in the Navakkiri GS area of Valikaamam East division. Some times referred to as a bottomless well or Deep Well, this well is caused by collapse of the top layer, exposing a limestone cavern connected to a underground water source. It is said that this well never dries up even during severe drought and the water is used by the farmers in the surrounding area. The dimensions of the well is 25 feet in length and 40 feet in width. As in many large public wells in the area, a flight of steps lead to the water level which is 14 feet below the surface level.

It is said that the 1st 40 feet of water in the well is fresh and turns saline further down. It is believed that this water source is connected to the Keeramali Freshwater Pool and said that a lime fruit thrown to to the well will appear in the Keeramali sea which lies 10km way from this well.

It is also said that the water level of the well falls and rises in synchronization with the low and high tide of the sea. Unfortunately no study of this well has been carried out partly due the 30 year bloody war with with Tamil Tiger Terrorists in this part of the country which ended in 2009. Fortunately a study of this curious well has been done in mind 1800’s and was published in the 1865-66 edition of the Journal of the Ceylon Branch of the Royal Asiatic Society of Great Britain & Ireland.

To ascertain at which depth the fresh water turns in to salt water, samples of water was taken at the depths of 45 feet, 95 feet and 145 feet using a special instrument with a valve and sealed in sealed. These bottles were sent to England for chemical analysis of the content. During the test it was found that the well was definitely not bottomless but reached the bottom at a death of 145-150 feet. It was observed that the samples of water brought from the bottom smelt of strongly of sulphureted hydrogen. It was also observed that the brackishness started between 40-50 feet in depth thus it was certain that the salt water enters the well at this height.

In the next experiment three researchers measured the water levels of the Jaffna Lagoon, Valvettithurai seas and the Nilavarai well every half an hour from 6 am to 6 pm. These measurements indicated that Valvettithurai and Nilavarai sea levels started to fall at 6.30 am and started to rise around 2-2.30 pm. But the water levels at the Nilavarai well fell in parallel with the seas at 6.30 but started to rise at 9.30 am and again fell after 2 pm. This meant that water levels in the well alternated 3 times a day while the tides alternated twice a day. Therefore the connection of the change of the water level in the well to the tides in the sea was disproved left the reason for the thrice daily water level changes in the well unanswered.

Recently (150 years later) an automated diving robot with divers of the Sri Lankan Navy conducted an expedition to the bottom of the well. They discovered that the bottom of the well lies 52.5 meters (172 feet). It was also discovered that fresh water existed in the first 18.3 meters (60 feet) and turned in to salty as it goes down.

Om Jaffna-distriktet

Jaffna er hovedstaden i den nordlige provins i Sri Lanka. 85% af befolkningen i distrikterne Jaffna og Kilinochchi er hinduer. Hinduerne følger den saivitiske tradition. Resten er overvejende romersk-katolikker eller protestanter, hvoraf nogle er efterkommere af koloniale bosættere, kendt som burgere. Tamilerne er opdelt langs kastelinjer, hvor landmandskasten Vellalar udgør flertallet. Fisk og skaldyr, rødløg og tobak er de vigtigste produkter i Jaffna.

Jaffna er hjemsted for smukke hindutempler. Et gammelt hollandsk fort står stadig velbevaret, indeni er en gammel kirke. Et andet eksempel på hollandsk arkitektur er Kongens Hus. Intet besøg i Jaffna er fuldendt uden at smage den udsøgte Jaffna-mango, der er kendt for sin sødme. Omkring 3 km væk ligger det majestætiske Nallur Kandaswamy-tempel, hjemsted for den største religiøse festival i Jaffna. Kayts Havn er et gammelt skibsdokningssted i Jaffna-regionen.

Om Nordprovinsen

Den Nordlige Provins er en af ​​Sri Lankas 9 provinser. Provinserne har eksisteret siden det 19. århundrede, men de havde ingen juridisk status før 1987, da den 13. ændring af Sri Lankas forfatning fra 1978 oprettede provinsråd. Mellem 1988 og 2006 blev provinsen midlertidigt fusioneret med den Østlige Provins for at danne den Nordøstlige Provins. Provinsens hovedstad er Jaffna.

Nordprovinsen ligger i det nordlige Sri Lanka og kun 35 km fra Indien. Provinsen er omgivet af Mannar-bugten og Palk-bugten mod vest, Palk-strædet mod nord, Bengalbugten mod øst og de østlige, nordlige centrale og nordvestlige provinser mod syd. Provinsen har en række laguner, hvoraf de største er Jaffna-lagunen, Nanthi Kadal, Chundikkulam-lagunen, Vadamarachchi-lagunen, Uppu Aru-lagunen, Kokkilai-lagunen, Nai Aru-lagunen og Chalai-lagunen. De fleste øer omkring Sri Lanka findes vest for Nordprovinsen. De største øer er: Kayts, Neduntivu, Karaitivu, Pungudutivu og Mandativu.

Den nordlige provins havde 1.311.776 indbyggere i 2007. Størstedelen af ​​befolkningen er srilankanske tamiler, med et mindretal af srilankanske maurere og singalesere. Srilankansk tamil er det primære sprog, der tales i provinsen af ​​langt størstedelen af ​​befolkningen. Det andet sprog, der tales, er singalesisk af 1 procent af befolkningen. Engelsk tales og forstås bredt i byerne.
