4. Tulip filter (Kjong filter)
Revolution on low cost water filters is reached with this ceramic carbon candle filter with impregnated collodial silver. The candle is bought in India and the filter is assembled in the IaW factory. For one family 1 candle is enough for 2 years of clean drinking water. Up to 3 candles per bucket is suitable for larger groups such as a class room.
5. The ‘Gulper’
The ‘Gulper’ is a manually operated handpump specifically designed to empty pit latrines.
It reduces the risk of contact with the pit contents and the operators and is a more effective means of emptying the pit. The cost of the unit is expected to be between around $120 — $160 depending on the model.
6. Rainwater harvesting tank
a. The Rain Cap:
A plastic lined tank designed in The Netherlands. It is a light in weight and easy install tank. Just dig a meter deep hole, hang the plastic lining in the hole, connect a pipe from the roof to the tank on one site and tap water from the other site.
A waterstorage tank of 1400L, storing rainwater and keeping it at drinking water quality. BOB comes in a easy package that weight 4kg and is smaller than a 20L water bucket. Unfold BOB, connect the inner and outer bag, adjust the tap and catch the rainwater at the top.
c. Harvest Tank
This is a design of tank from Thailand which uses curved cement segments joined together and rendered. It offers great opportunity for people to assist with manufacture or do it themselves for this 3200ltr tank.
7. Building a Distribution Channel
Appropriate technology is only appropriate if people really are able to use it.
That means that the gap between innovations and possibilities for purchasing these techniques needs to be closed.
IaW is committed to set up a sustainable and donor-independent distribution channel in which
- a choice of products
- at the right and honest price
- will be offered with micro credits
This last benefit will make it possible for buyers to also build up credit history that can benefit them at a later point. IaW will be the guarantor for its products and therefore each product will be its own collateral. For the micro credit provider it means access to a large group that has never been their customer and they might be able to lower their interest rate.
IaW uses Alibre Design Professional for our mechanical design and drawings and we would like to express thanks to Alibre for their support and assistance with our work in Cambodia.
