Sand dam road crossings

At Excellent Development we believe incorporating the principles of sand dam technology with low volume road crossing designs will deliver a more robust and cost-effective rural roads infrastructure.

Sand dam road crossings will:

Minimise costs of repair and reconstruction.
Improve reliable access to markets and services.
Reduce local fl ooding and erosion.
Recharge groundwater.
Supply millions of litres of safe water for multiple use.
Contribute to climate change resilience.

"With this new water tank, life in school will be more fun"

The difference made by having water at school

Attending a school that lacks a reliable water source presents many challenges for students. Speaking to members of the Kasunguni Secondary School community, we find out the ways a school water tank has helped them to address these challenges.
Tsavo, Kenya (Partner: Tsavo Trust)

The objectives of the sand dam programme are to both provide year round water for the wildlife living in Tsavo National Park, as well as restore degraded and fragile land through enabling vegetation re-growth.

School water tanks

Water tanks store rainwater collected from the roof of schools. A typical school water tank can collect up to 104,000 litres of water, and they refill every rainy season. Each water tank can last over 25 years and require little maintenance. Each one provides water for generations of children.
Rock catchments

Since 2002, Excellent has supported communities to build 12 rock catchments, with each one able to collect up to 104,000 litres per tank for domestic use.

A brighter future with water
