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.

John Gives A Dam

I'm participating in the Kenya February 2020 expedition to provide water access to rural Kenyans, but more importantly, to give the women and children of the community closer access to quality water sources so they can spend more time on education, health care, and economic development. I'm excited for what should be a trip of a lifetime!

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.
