Cambodian “Easy Latrine” wins international design award

A low-cost pour-flush latrines, especially developed for a project in Cambodia, has won a prestigious international design award.

The ‘Easy Latrine’, designed by Jeff Chapin while on sabbatical from IDEO, was one of three winners named Best in Show by the jury of the 2010 IDEA awards. The International Design Excellence Award (IDEA) is an annual competition organised by IDSA, the Industrial Designers Society of America.

Chapin designed the ‘Easy Latrine’ at the request of International Development Enterprises (IDE) for the Sanitation Marketing Project that was launched in Cambodia in early October 2009, under funding from USAID and the World Bank Water and Sanitation Program (WSP).

Village masons can build ‘Easy Latrines’ themselves from locally available parts. It consists of a pan, a bucket of water with a ladle, and pipes to connect a hut to a latrine buried in the ground. The latrine itself has three receptacles made of rings of concrete bound by the ash of rice husks — material that’s readily at hand and much cheaper than cement. Once a receptacle is full, it can be capped, and after two years, the sediment can be used as compost.

One latrine costs about $25 and more than 2,500 have already been purchased and installed by villagers. The aim to install 10,000 latrines by April 2011, all without subsidy as prescribed by the Community-Led Total Sanitation (CLTS) approach that the project is following.

Local producers are receiving training in sanitation and hygiene education, latrine production, and basic business and sales management. They are asked to invest a minimum of US$500 and produce three latrines per day.  A local mason—having seen his monthly income jump from US$50 to nearly US$400 in a matter of weeks—decided to invest more by purchasing another trailer for his motorbike in order to deliver more latrines to villages. He has also begun to sell his latrines to supply shops in the region as a secondary means of distribution. One supply shop is even selling the latrine core without making a profit, as they expect to earn their profits from the above-ground components that they will sell in conjunction with the core.

The IDEA jurors loved the clear thinking behind every aspect of the design of the ‘Easy Latrine’. Chapin and his team “understood how to bring the idea to the community, how the product would be made, and how it would be sustained,” says jury head John Barratt. “It’s an integration of strategy, service design, and product design.”

India: government announces that four more states have no dry latrines

According to Housing and Urban Poverty Alleviation Minister Kumari Selja, within the last one year, the states of Andhra Pradesh, West Bengal, Nagaland and Assam have announced that they have no dry latrines, implying that manual scavenging has effectively been abolished.

The government claims there are only four states left with dry latrines: Bihar, Uttarakhand, Jammu & Kashmir and Uttar Pradesh. This contradicts a May 2009 news report that the Supreme Court had sent notices to the governments of Delhi, Punjab, Haryana and Rajasthan seeking an explanation for their failure to demolish dry latrines and prosecute the owners.

Under the revised guidelines of the government’s “Integrated Low Cost Sanitation” (ILCS) scheme, a total of 241,931 dry latrines are being converted into pour-flush latrines and 32,305 new pour-flush latrines are being constructed during 2008-2009 and 2009-10 (up to 31.08.2009).

The ILCS scheme was initiated in 1980-81 through the Ministry of Home Affairs and later through Ministry of Social Justice & Empowerment. The scheme was transferred in 1989-90 to the Ministry of Urban Development & Poverty Alleviation and from 2003-2004 onwards to the Ministry of Urban Employment and Poverty Alleviation/Housing and Urban Poverty Alleviation (UEPA/HUPA). The scheme has helped in constructing/converting over 2.8 million latrines to liberate over 60,000 scavengers so far. To improve the programme’s performance revised guidelines were introduced in January, 2008.

The main objective of the Scheme is to convert low cost sanitation units through sanitary two pit pour flush latrines with superstructures and appropriate variations to suit local conditions (area specific latrines), but 25% of the funds of the scheme are also made available for construction of new latrines where economically weaker section (EWS) households have no latrines.

Under the Scheme, the central subsidy is 75%, State Subsidy 15% and beneficiary share is 10%. The upper ceiling cost is Rs.10,000/- (US$ 214) for the complete unit. For the States falling in the category of difficult and hilly areas, 25% extra cost is provided.

The Scheme is scheduled to end in 2009-10.

India: use pour flush system in toilets to save water, UNICEF

UNICEF has called for promoting Pour Flush System in toilets stating it is far better than the traditional Tank Flush System as it saves water.

Water Environment Sanitation (WES) specialist from UNICEF, Amit Mehrotra, said this in a press conference on Total Sanitation Campaign in Lucknow, India.

He said a large quantity of water gest wasted in the old Flush Tank System in urban areas. To preserve water, Pour Flush System should be promoted in the country.

”More than 65 per cent people go outside for defecation in our country and without changing this picture, we cannot even think about the healthy India,” Mr Mehrotra said.

He added that UNICEF has set a target with government’s collaboration to construct two crore [20 million] toilets in rural areas. One crore [10 millon] toilets have been constructed so far.

”We do not have enough trained workers to construct such toilets. As per the requirement, at least one trained worker is needed in one village to reach the target but we have only 16 per cent trained workers till date,” said Mr Mehrotra.

He said UNICEF has worked on sanitation in 10 districts of Varansai region.
