Grid Score Contribution


To help us direct our investments, we use a tool called the Development Impact Grid. The Grid scores every investment we plan out of a score of four, based on two factors: the difficulty of investing in the country and whether investment in that sector will lead to jobs.

Grid score: n/a for Catalyst transactions. Roserve’s integrated wastewater recycling service model remains to be proven at scale in South Asia and Africa.


Relates to the risk that the investment will fail to catalyse the water services market in India. Considered high given i) the inherently unpredictable nature of nascent markets, and ii) Roserve currently has insufficient pipeline to deploy the facility;

Expected impact

Roserve will help to demonstrate the potential for commercial water recycling in India, this is expected to accelerate the expansion of the market for water service companies increasing the recycling rates. The facility is expected to support water savings of over 25 million litres per day.

Environmental and social aspects

As part of the investment process CDC ensured Roserve met international environmental (E&S) performance standards.

Key facts


Since 2012, we’ve only invested in Africa and South Asia. Investments outside these regions are from our pre-2012 portfolio.

South Asia

We have seven priority sectors. However, we continue to invest outside these sectors, largely in the most challenging regions, as new investment supporting any sector helps to underpin the private sector, and create jobs and livelihoods for people.
