“…Several researchers have developed/applied models for optimizing tank size and assessing storage tank performance (Ndomba & Wambura 2010;Campisano & Modica 2012;Imteaz et al 2012;Mun & Han 2012;Katambara 2013). Most such analyses consider fixed demand through the year, regardless of the variable nature of rainfall.…”

The extensive application of rainwater harvesting (RWH) projects is inhibited by the challenge posed by the dry seasons. In a case study of Mnyundo Primary School, Tanzania, the performance of the RWH system was evaluated using a daily water balance model. The methodology is based on defined dry season parameters – no water days (NWDs), rainwater usage ratio (RUR), and water level in local water storages; while the system operational methods involve users adopting either fixed (constant) demand or variable demand (demand varying with respect to available water in the storage tank), throughout the system utilization. Additionally, the cost of installing an RWH system to achieve a substantial reduction of NWDs to zero was calculated. It was established that the existing system cannot achieve zero NWDs under consideration of both operational methods. However, the greater the number of tanks, the lower the NWD, and in the variable demand operational method, better RUR was achieved. For mitigating water shortages in the dry season, the school should adopt RWH in two buildings under the demand scenario (300 ≤ demand ≤ 900 L/d, for the respective water levels in the storage tanks), yielding 58% RUR. The performance of the system can be improved by monitoring water levels and adhering to demand guidelines. These are useful strategies for practitioners in water supply.

“…Rainwater is considered a viable alternative where water is saline, as in the case of the study area. Scholars have, however, found that the practice of rainwater harvesting is still low in Tanzania (Katambara, 2013; Mwamila, Han, & Katambara, 2016; Umeodum et al, 2019).…”

In a bid to improve water supply Tanzania changed its water policy in 2002. It is now almost two decades and water problems have remained a prominent issue. Community leadership is required to ensure increased access to safe water by enhancing effective community engagement in operation and management of water resources. The current study investigated the roles of community leadership in water supply through self‐help initiatives in the Morogoro region. A total of 365 household heads were randomly selected for a survey. Descriptive and inferential statistics were used for data analysis. Results show that there is a significant positive relationship (r = 0.562 at p < .001) between community leadership and self‐help initiatives. Good leadership practices promote self‐help actions in water supply services. However, lack of accountability in the management of community water funds as well as leaders’ inability to lead by self‐help actions are examples of leadership ineffectiveness that currently hampers community self‐help initiatives. As such, addressing the current water problems in rural Tanzanian communities in a sustainable manner requires investments in programs that empower community leadership, and in some situations, alongside the development of water infrastructure.

Tackling rainwater shortages during dry seasons using a socio-technical operational strategy

The management of water resources during the dry season is a major challenge associated with rainwater harvesting (RWH) technology, but is necessary given the human suffering that follows from resulting conditions of water scarcity. In this study, the parameters for dry season assessment are defined in terms of ‘no water days’ (NWD) and rainwater usage ratio. A simple socio-technical operational strategy making use of a water level monitoring system is proposed for NWD reduction. This involves water level monitoring, whereby daily water demand varies with user cooperation, as based on the available water in a tank. The results of our study show that an NWD as low as 10 can be achieved as compared with the current value of 115 days, before considering investment on additional roof catchments and tank volume. These parameters are useful for analyzing any type of rooftop RWH system. Furthermore, this operational strategy can be made practical and simplified by incorporating an easily visible and understood guideline onto the RWH system. This strategy is replicable anywhere in the world, with consideration of site-specific conditions such as rainfall amounts, roof sizes, and population.
