Maximising the Use of Waste Water

We are now in the middle of November and are still waiting for the first serious rains of the winter. The Sea of Galillee is fast approaching its black line, the line at which serious damage to the eco system will occur.

Desalination plants are coming on stream one by one, but the need to recycle waste water is paramount.

Out of a total of 500 million cubic meters (MCM) of sewage produced in Israel in 2008, about 70% of the effluents were reclaimed, a figure not many countries can claim to reach.

Local authorities are responsible for the treatment of municipal sewage. In recent years new or upgraded intensive treatment plants were set up in municipalities throughout the country. The ultimate objective is to treat 100% of Israel's wastewater to a level enabling unrestricted irrigation in accordance with soil sensitivity and without risk to soil and water sources.

Some Facts and Figures

500 MCM of wastewater were produced in Israel in 2008

31% MCM of the effluents underwent tertiary treatment (155 MCM)

55% of the wastewater underwent secondary treatment (275 MCM)

92% of the wastewater was adequately treated (460 MCM)

8% of the wastewater remained untreated.

We still need to pray for rain and after the current hot spell with temperatures in the 90's is due to end tomorrow, we have been told by the forecasters to expect rain. Let's hope they are right.
