Introduction to Operation OASIS

The massive waste water problem that currently pollutes our bathing waters costing £billions to process throughout the world can be used to irrigate and reforest desert coastlines to induce rainfall.

Our aim is to use the return ballast capacity of super crude carriers which currently transport sea water half way around the world at great financial and environmental cost. This ballast is discharged into the sea, often introducing invasive marine species which affects the stability of indigenous species of flora and fauna.

The E.U. is legislating against this practice and tanker operators will be forced to seek an alternative.

Operation OASIS offers an exciting opportunity for ballast water. Transporting treated waste water to irrigate and reforest arid coastlines to induce rainfall has to be the way forward.

One tanker loaded with 300000 cubic meters of treated waste water would support 57 hectares of forest for a whole year.

Reclaiming deserts to enable people to feed themselves and grow great forests will offset the carbon emissions from shipping.

With global food shortages upon us we are already feeling the strain on our pockets in the developed world and renewable resources are in rapid decline. Drought is affecting all major food producing countries and wells are running dry. Water scarcity poses major problems for us and our children. We need to act fast in order to avert a major global catastrophe.

When the mighty river Amazon dries up and it's fish stocks die it is time to take stock on how we manage our fragile environment. For more detailed information visit our website and forum at:

Duchy Sewage could help the desert bloom

Cornish Guardian, 23/9/93 by Sue Doyle
Duchy Sewage could help the desert bloom
Ships that pass in the night could well link Cornwall and the land of the Nile if the vision of one of the campaigners who visited the Surf To Save contest last week is realised.
Mr Andrew Fletcher from Paignton, travelled to the contest to promote "Operation Oasis"-the use of sewage and waste water as a fertiliser in the arid deserts of Egypt. He thinks it should be possible to use the returning super tankers after they have offloaded oil in this country, to transport effluents back again.
Once unshipped in the Near and Far East, whole areas of desert could be sprayed with liquid mulch made from sewage and waste water. The Mixture would bind with the sand grains to create a fertile crust of top soil, where trees and plants could grow to slow down evaporation.
If additional water was needed it could be pumped from underground using methane also derived from the sewage.
Mr Fletcher's occurred to him some years ago, but only recently has he decided to follow it up, following a discussion with an Egyptian Doctor, Dr Awad told him that as only three per cent of the land on either side of the Nile is fertile, the populations there suffer from a paucity of good soil. He urged him to make his plan public.
The Egyptian Embassy in London has responded with interest in the idea.
One persons annual faeces outlet is equivalent to a 25kg sack of EEC 20:10:10: NPK fertiliser.
Despite its potential no ultimate strategy has ever evolved for dealing with it usefully in a widespread way.
Recently South West Water has been encouraging experiments with land reclamation in the baron clay tip areas of Cornwall, by giving treated sewage cake or powdered form to the ECCI horticultural department.
Experiments are underway to see what combination of sewage and infertile soil are best for growing grass and later trees and crops.
These experiments started only last Spring-an indication of how recent an idea this is.
A SWW official explained that all the sewage sludge collected from cesspits in the county is used on farmlands here (on two hundred and fifty farms in all).
He thought that demand far outstripped the ability to supply as only 1/200th of available land is covered. 'Possibly because no one wants the stuff and already have a massive problem dealing with the waste generated by farm animals,'
If there were inland treatment works for sewage from areas such as Newquay, eventual export of effluents would become more likely, but at present there are only limited supplies of "human fertiliser" for land use.
Mr Fletcher's comments that if we continue dumping sewage in the sea, not only will we ruin the marine environment, we will lose a valuable soil compost.
His idea compares with a scheme piloted some years ago in Kinshasa, Zaire, for using grow-bags filled with a mixture of earth and excrement.
Called "The Eco-Lavatory" the bags were used to nurture plants again in arid and infertile regions.
Seeds where sown in holes in the plastic bags, which were sunk into the land.
The bags had the advantage of preventing the spread of contamination and retaining water.
Perhaps the most novel use for sewage is the one sited by Surfers Against Sewage in its Campaign Journal, Pipeline News.
In Japan treated sewage is compacted into paving slabs... insoluble it is hoped in water.
