In order to evaluate whether installed water storage capacity for single-family households in Accra are large enough to harness the full potential of rainwater harvesting (RWH), we compare this capacity, and its associated days storage, with that required for RWH, and examine the relationship between roof area, household size and each of these storage capacities. Results show that (1) installed capacity is 25.6 m3 significantly smaller, and more varied, than that required for RWH; (2) consequently, the associated days storage for installed capacity is 110 days significantly smaller, and more varied, than that for RWH; (3) unlike the capacity for RWH, which had a significant relationship with only roof area, there was no significant relationship between roof area, household size and installed capacity. We conclude that the decision on installed storage capacity ignores the potential of RWH, thereby, making it smaller than what is required to harness this potential.
