How does this work?

This statistics dashboard amalgamates data from various sources to show information on all systems installed by Tatirano Social Enterprise. You can see where our systems are, their capacity, rainwater harvesting potential, maintenance history, photos, and other information about the system. For most systems, you can see the amount of water dispensed, and estimated current volumes where the data is available. We also provide accurate beneficiary estimates, and water quality test results.

Types of system

School
Provides water to a school or educational institution.
Community kiosk
Provides water for public consumption for a small fee.
School/Community kiosk
Provides water to a school as well as a public kiosk.
CSB
Provides water for a public health clinic or hospital.
Household
Provides water for a private individual or organisation.

Tank types

Concrete
Reinforced concrete "Calabash" tank.
Labasy
Welded tarpaulin bladder tank.

Technical terms

Total collection area
The area (typically of a roof) in metres squared collecting rainfall which is fed into the system.
Collection potential
The total amount of water a system could be expected to harvest in a period, given average rainfall in the location and collection area.
Beneficiaries
People using a Tatirano system. Further information on how we calculate these figures is available in-context.

Water quality testing

We regularly monitor the quality of water provided by our systems to check it is clean and safe, and carry out maintenance work if there are any issues. The parameters tested are:

Conductivity
Measures the salinity of a water source. The sea, for example, has a conductivity of between 40-50,000 micro siemens per cm, whilst the WHO recommends drinking water to be <2000 micro siemens per cm.
Temperature
Measured to ensure that no extremes are experienced since extremely high or low temperatures can vary other parameters, such as conductivity and CFU.
pH
Taken to ensure that there are no spikes in acidity which can be detrimental to health upon consumption, with a target pH of 7. Acidity can be an indication of external pollution (man-made or natural) in the surrounding environment. In fact, Tatirano's ferrocement calabash tanks usually measure more alkaline (between 8-10 pH) because of the infiltration of cement into the water. High alkaline water is sometimes sought after for its health benefits.
Total Dissolved Solids (TDS)
In layman's terms, this is the amount of combined organic and inorganic solids in a water sample and can be an indicator of general water quality. The WHO states that a TDS of greater than 600g/l usually begins to become unpalatable.
Colony Forming Units (CFU)
CFU (colony forming units) or TTC (thermotolerant coliforms) per 100 ml are measured to give the microbial quality of the water. Put literally, TTCs are the number of microbes that can withstand 44°C, and thus originate from the gut of a mammal. These are the harmful bacteria that make people sick and the WHO targets 0/100 ml for drinking water, although <10/100 ml is usually considered low risk and acceptable for community water sources.
