Calculation Details
1. Determining Functionality of Point water sources
=
Sum of Fuctional (PS +SW + DBH + RHT + PSP + KSK + YT) x 100
Sum of Fuctional & Non-Functional (PS +SW + DBH + RHT + PSP + KSK + YT)
2. WfP functionality
=
Sum of Fuctional (Dam + VT) x 100
Total (Dam + VT)
3. Total sources
Sum of Fuctional & Non-Functional (PS +SW + DBH + RHT + Dam + VT + PSP + KSK + YT)
NB: However in calculating some indicators, Dams and Valley tanks are not included as
shall be specified in this document.
4. Population served
This calcualted in a series of steps given that this data is being picked from 3 different but
related sources. i.e.
i. Form Ones (Point Water Sources ),
ii. Form Two (Piped Schemes),
iii. NWSC (National Water & Sewerage Corporation)
STEP 1: Population served for Point Water Sources a.k.a Form One
POPSERVED_1 =
(PSx200) + (SWx300) + (DBHx300) + (Damx0) + (VTx0 ) + (PSPx150) + (KSKx150) + (Ytx150)
+ (if RHT < 10000 or RHT = 0 then RHTx3 ELSEIF (RHT > 9999) then RHTx6 )
STEP 2: Population served for Piped Schemes a.k.a Form Two excluding public taps
POPSERVED_2 =
(HCx6) + ((YTF2-YT_F1)*24)X + (ICx100)
NBX: A correction factor on Yard taps has been included. There are yard taps in Form One
(Point Water Sources) and yard taps in Form Two (Pumped Piped Schemes). Many of these
yard taps had been counted twice i.e. once in each form and this would inflate the
population figures. Thus a correction fcator was required. This has been done as follows.
(YT F2-YTF1)*24 + YT F1 *150
STEP 3: Population served for NWSC
POPSERVED_3 =
Population served as stated by NWSC
NB: In areas served by NWSC only NWSC data has been considered. E.g. Bushenyi TC,
Iganga TC, Jinja Municipality among others. The Point water sources have been deleted.
STEP 4: Total Population Served
POPULATION SERVED = [ POPSERVED_1 + POPSERVED_2 + POPSERVED_3]
STEP 5: Capping Total Population Served
IF POPULATION SERVED > 95% of Population (UBOS)
THEN POPULATION SERVED = 95% OF Population (UBOS)
ELSE POPULATION SERVED = POPULATION SERVED

8. Rural/Urban Administrative units
Most subcounties are either rural or urban. However some subcounties are partly rural
and partly urban as they contain TC’s. The official UBOS population data exists for this TC’s
in subcounties in the SIM document. Thus by using the TC population figures as
percentagess of the total subcounty population data, we are able to derive a percentage
for urban & rural population.

The percentages derived from these calcualtions become the basis of calculations that
have a breakdown of Rural/Urban e.g. Functionality, Population served, Coverage and
equity
NB: Total sources =
Sum of Fuctional & Non-Functional (PS +SW + DBH + RHT + PSP + KSK + YT) i.e. exclusive
of Dams and Vallet Tanks
A. Rural Functionality
=
Rural % x Sum of Fuctional (Total Sources)
Rural % x Sum of Fuctional & Non-Functional(Total Sources)
B. Urban Functionality
=
Urban % x Sum of Fuctional (Total Sources)
Urban % x Sum of Fuctional & Non-Functional(Total Sources)
C. Rural Population Served
=
Rural % x Population Served
Rural % x Population (UBOS)
D. Urban Functionality
=
Urban % x Population Served
Urban % x Population (UBOS)
E. Etc
NB: If an administrative area is all rural then all items e.g. Functional (Total sources) are all
considered as rural. i.e. nothing gets left out. This is the same for cases where the wholes
subcounty is urban.
9. Deviation and Equity
NB: Only Rural areas (subcounty) have been considered in calculating deviation and equity
This is done at National Level & District Level
Steps 1:
Sum all Functional & Non-functional Point Water sources (Form One) excluding Dams and
Valley tanks in rural areas only i.e.
Total sources = Sum of Fuctional & Non-Functional (PS +SW + DBH + RHT + PSP + KSK + YT)
NB: If this subcounty is partly rural & urban then take the derived percentage/fraction of
its rural part then multiply it by the total sources. However if it is 100% rural then take all
sources.
STEP 2:
Pick the population for the subcounty.
NB: If this subcounty is partly rural & urban then take the derived percentage/fraction of
its rural part then multiply it by the total sources. However if it is 100% rural then take all
sources.

Parameters for all Calcualtions:

Population projections - 2010 – 2011

Down time -

Coverage capping -

Urban Areas - All Town Councils and Municipalities (including their subcounties are
considered 100% urban). Added to these are subcounties that have a town council. Here a
percentage of the urban and percentage of rural is derived. This is done only for TC that have
a population data in the SIM document.

NWSC
- In areas where NWSC is operational no DWD data (point sources or piped
schemes data has been considered in the calculations)
