Dear Van Vander Plas, Both ...

Dear Van Vander Plas,

Both option some merits & demerits the tanker supply running cost is high and the pipe line supply one time investment I am giving my thought on that , firstly ,there is need of calculating the quantity of water that we have to supply to customers then line losses to be added to calculated quantity of supply and some % of addition of supply quantities for our new service reservoir design,however the increase in population would also lead to the increased waste water flows as well. Population is 60000 suppose one people requirement is 100 lit then total water requirements is 6000 m3/day or 250 m3/hr. According to capacity you can design line ID. Submarine pipelines may be very effective under favourable conditions. Investigations and feasibility studies are necessary to determine the costs and risks involved.

Advantages

This technology incurs minimal operational costs if operated with a gravity-fed supply. It also permits diversion of water from water-rich areas to water-poor areas.

Disadvantages

This technology incurs very high engineering and construction costs, the line can damaged by tides, storm etc.

Some examples of pipe line under ocean

1. Northern Cyprus Water Supply Project, Turkish Republic of Northern Cyprus Water Supply Project

The Northern Cyprus Water Supply Project for transporting water to Cyprus was to be completed in September 2014

The high-density polyethylene underwater pipeline with 1,600 mm (5 ft 3 in) diameter is 80.151 km (49.804 mi) long and is suspended at a depth of 250 m (820 ft)

The pipeline has transferrd annually 75 million m³ water from the Alaköprü Dam on the Anamur-Dragon Creek in Turkey to the Geçitköy Dam in Northern Cyprus.

3. In late 2013, Makai was contracted by a joint venture between Sigur Ros and Kalyon Group to perform deployment analysis for the on-bottom portion of a 63” (1.6m) diameter, 66 mile (107 km) long HDPE pipeline to transmit drinking water from the Turkish mainland to the island of Cyprus (Turkish Republic of Northern Cyprus). Makai performed pipe stress analysis, design of the holdfasts, pipe weights, and bridle system, and final deployment analysis and guidelines.
