Lack of modern sanitation systems threatens groundwater, health

from IRIN

CAIRO, 3 March 2008 (IRIN) - Nearly all Egyptians - 98 percent of the population - have access to piped water but only some have proper sanitation facilities. Not much attention has been paid to the effective and safe disposal of sewage, especially in rural areas, say specialists.

In rural areas - deserts and agricultural areas alike - only 58 percent of inhabitants have access to any kind of sanitation, said Rania El-Essawi, water, environment and sanitation officer at the Cairo office of the UN Children’s Fund (UNICEF). Most rural sanitation is primitive, and does not involve a proper sewage system.

Toilets generally have either one or two pits, with some kind of elementary filtration mechanism. They may or may not be regularly emptied, and they are not necessarily in households. Latrines may be at local community centres, including local mosques. Waste is either reused or removed by an evacuation truck.

A recent report by Water Aid ranks Egypt the 16th worst place in the world sanitation table.

Millennium Development Goal

The UN water and sanitation Millennium Development Goal implies that Egypt must provide sanitation to 77 percent of its 80 million people by 2015, El-Essawi said. Currently at 70 percent, Egypt appears to be on track, she added.

Yet numbers alone do not tell the full story. The type of sanitation, its potential for contaminating groundwater, its impact on human health, attitudes, education and behavioural change are important factors.

“Sanitation is not [measured] by square metre or by population… There are people with no access and there are people with partial access,” said Mahib Abdelghaffar, a professor of civil engineering at Cairo University.

Agricultural areas

For people in many rural areas, sanitation is simply a hole in the ground, sometimes covered by a ceramic “squat” platform.

In the Nile delta area, which makes up only 2.5 percent of Egypt’s land mass but is home to over a third of the population, people mainly use holes in the ground since they lack sewage systems, El-Essawi said.

“In many households it’s just a hole in the ground… there is no evacuation [the waste is removed for a fee], there is no filtration. They have no way to get rid of massive amounts of liquid waste,” El-Essawi said.

In agricultural areas, latrines - if they exist at all - sometimes overflow or are emptied before the faecal matter has turned into fertilizer. This often leads to groundwater contamination, potentially causing a health hazard to the local population.

“The problem is all near the delta… The houses in delta villages should all be connected to a proper sewage network,” said Abdelghaffar, adding that in some communities, stepping stones help people avoid stepping in sewage as they cross roads.

Desert areas

There is less risk of groundwater contamination in desert areas, where groundwater is deep below the surface and the sand is very porous, so liquid is absorbed and the groundwater remains clean.

A problem in rural areas generally is that toilets and latrines are not kept clean and maintained, and are sometimes built in the wrong place.

Health

Proper disposal of waste would help protect people from diseases arising from water contamination, such as typhoid, diarrhoea, polio, bilharzia and hepatitis C.

“These [diseases] are life-threatening and fatal. One fifth of child mortality deaths are attributed to diarrhoea which is a big threat in Egypt, together with bilharzia,” El-Essawi said. “People need to know how to properly use water so they don’t contaminate it.”

Intermediate solutions

UNICEF promotes intermediate sanitation technology, such as ensuring that latrines are properly built, and attempting to provide basic sanitation services to families until they can access a more advanced sewage system, El-Essawi said.

“You want to provide services such that people can benefit from them,” she said. “Everybody has a right to services that do not affect their health.”
