Comparative water quality analysis for road runoff water, case-study Kenya

A report that compares water quality parameters of water harvest from roads, rock catchment, river, borehole and a shallow well. It concludes that the water quality of road runoff is better off compared to other sources, only issues along road being exceeding values of high iron and turbidity. This can be prevented/treated with appropriate measures. Overall there is huge potential of road runoff also to be used for domestic use.

How to make roads work for resilience in Nepal?

Nepal is a challenging country for road design and construction: the low-lying plains that are prone to flooding and inundation, hilly areas with a lot of irrigation potential, and the mountains with very steep slopes.

We presented and discussed the challenges and opportunities at the Department of Roads. There is a lot of potential to turn roads into an asset for water management. The engineers indicated that the policy-aspect is very important, it needs to be included in decision-making.

Roads for Water Guided Learning Package

This training course has been established to familiarize participants with road water management
approaches and technologies. The participants will be enabled to apply the acquired knowledge
and skills in their area to find possibilities to improve the present situation and plan for the
future.

Road Crossings for Water Harvesting in Dry Rivers: Non-Vented Drifts as Sand Dams

This Practical Note discusses the siting, the design and the construction of road crossings in dry
riverbeds to harvest and retain flood water. With extensive road construction programs ongoing in
most part of the world and 60% of new roads to be added from 2010 to 2025 globally, the
opportunities to combine road development with water management are substantial. Within this the
use of road drifts – in particular the use of nonvented drifts functioning as sand dams in semiarid
and arid areas – is an important and in most countries underutilized opportunity to harvest flood
water. Read the note here.
