Installation of water tanks – Jambiani

Identification of the need

Jambiani is a region located in eastern Zanzibar, Tanzania. In Jambiani, water is a limited resource, and one of the main problems is the lack of access to drinking water in the homes of local inhabitants of the area.

Currently, they have a well from which water is obtained through pipes that reach the center of Jambiani Village. The route of the pipes goes from the well to different strategic points in Jambiani; where, through taps already installed, inhabitants have the possibility of obtaining water (not purified) for washing, cooking, etc.

This installation has greatly helped the population to avoid long trips to get water. However, there are still some drawbacks that prevent adequate access to this resource:

• The water from these taps comes from the aforementioned well; However, only for a duration of 4 hours a day and during the morning, preventing the inhabitants from having water for the rest of the day.
• The pipe network is extensive and sometimes the electrical power is not enough for the water pump to generate enough pressure to reach the different points of the network, especially if the different access points are used simultaneously.
• Power outages are common in Jambiani, which in turn means that residents do not have access to water during these outages.

Proposed solution

To address this issue, water tanks have been installed to facilitate collection. This ensures that the water tank reserve can be utilized in situations where access through the taps is unavailable.

Each water tank installation consists of:

• A brick base on which the tank will be installed.
• A tank with a capacity of 5,000 litres.
• Pipes and taps for connection to the water network.

A total of 4 water tanks are to be installed, and their current situation is as follows:

• Water tank 1: Installation completed.
• Water tank 2: Base built and pipes installed.
• Water tank 3: Base under construction.
• Water tank 4: Not started.
