The main objective of this assignment is to document the proportion of Nigerians that have access to safe water and sanitation facilities and those who otherwise, do not have
The main objective of this assignment is to document the proportion of Nigerians that have access to safe water and sanitation facilities and those who otherwise, do not have, according to the following definitions:
i. Access to Water Supply: The availability of at least 20 litres per person per day of improved water supply from a source within 250 metres of user's dwelling.
ii. Access to Sanitation: Sanitation can be defined as the availability of improved disposal facilities of human wastes that can effectively prevent human, animal and insect contact with the human wastes.
iii. Improved Water Supply: The following technologies are included in the assessment as representing improved water supply:
a) Household connections,
b) Public standpipes, borehole, protected dug well, protected spring, and rainwater harvesting.
iv. Not- Improved Water Supply: The following technologies are considered “not improved”:
a) Unprotected well,
b) Unprotected spring, vendor-provided water,
c) Bottled water, tanker truck-provided water,
d) Streams and ponds.
v. Improved Sanitation: The following technologies are considered “improved”,
a) Connection to a public sewer,
b) Connection to septic system,
c) Pour-flush latrine,
d) Simple pit latrine
e) Sanplat,
f) Ventilated improved pit latrine.
vi. Not-Improved Sanitation: The following technologies are considered “not improved”:
a) Service or bucket latrines (where excreta are manually removed),
b) Latrines with an open pit,
c) Defecation in bushes

Scope
The scope of the National Water Supply and Sanitation Baseline Survey includes the following:
- Water Supply Facility Survey: To capture the location, attributes, and operational status of water supply facilities.
- Water Supply Agency Operational Survey: To collect data on the profile of water agencies in the state, in terms of production assets, capacity utilization, manpower; and financial sustainability.
- Sanitation Facility Survey: To capture the location, types and conditions of sanitation facilities.
- Water Related Diseases Survey: To collect data on reported cases of water related diseases from health institutions.
- Household Survey: To capture data on the proportion of households that have access to safe drinking water and sanitation facilities and prevalence of water related diseases in each community

Coverage
National
Households in all the 8,800 Political Wards,a total of twenty-two (22) houses for the ward
The surveys are to be carried out in all settlements that should be properly classified as:
- Rural Areas are settlements with a population of less than 5000 people
- Small Towns are settlements with a population between 5000 and 20,000 people
- Urban Areas and Towns with a population more than 20,000 people
- State Capitals and political capitals of the 36 States and FCT in Nigeria

Sampling
Households in all the 8,800 Political Wards spread across the 774 LGAs in 36 states and FCT were surveyed. The Baseline consultants administered survey questionnaires to take stock of sources of drinkable water, the volume/cost of water consumption; the sanitation facility and occurrences of water related diseases in households surveyed.
Selection of Location and Households
The Baseline consultants sensitized members of the community through the councillors and other recognized leaders about the exercise to forestall any suspicion or misconception about the survey. Baseline supervisors documented the survey process in each community by stating the names of councillors, community leaders met, list of all communities identified in each political ward and the ones selected for survey, without forgetting to state all the problems encountered in the survey process.
A typical Nigerian settlement, regardless of its population is either a multi community ward or a multi ward community. But in either case, the Baseline Consultants were to ensure that the selection of the households took into cognisance the geographical spread and socio-economic variance of the ward. It should be noted that in every ward, the selected houses were to be enumerated through a transect walk and the first sampling element, which should be the first house on the right or left, would determine the subsequent ones to be selected.
Multi-Community Ward
The Baseline consultants were to go through the list of all communities or villages in each ward out of which two (2) would be randomly selected. Starting with the first community, a minimum of eleven (11) houses would be systematically selected from the listed households, after determining the sample interval. The sampling interval for the community would be determined by dividing the total number of houses in it by eleven (11). This process would be repeated for the second community to arrive at a total of twenty-two (22) houses for the ward.
Multi Ward Community
The Baseline Consultants were to go through the list of streets, quarters, discrete areas, housing estates, or haphazardly located homes with no identifiable streets in the ward, where a random sample of 22 houses would be systematically selected. However, where there were no streets, the Baseline Consultants would demarcate the ward into appropriate blocks and select two blocks randomly. The houses in each block would be listed and eleven (11) houses systematically selected.
No deviations
Unable to calculate the response rate because the report was not accessable as at the time of archiving
The data has been weighted but the variable used was not in the data set.
Note that the data set are not raw data.
Survey instrument
The data collection forms are:
- Water Supply Facility Survey: To capture the location, attributes, and operational status of water supply facilities.
- Water Supply Agency Operational Survey: To collect data on the profile of water agencies in the state, in terms of production assets, capacity utilization, manpower; and financial sustainability.
- Sanitation Facility Survey: To capture the location, types and conditions of sanitation facilities.
- Water Related Diseases Survey: To collect data on reported cases of water related diseases from health institutions.
- Household Survey: To capture data on the proportion of households that have access to safe drinking water and sanitation facilities and prevalence of water related diseases in each community.
Data collection

| 2006 | 2006 |
The database software recommended is MS Access 2000. The MIS Consultants have developed an application software, which has an MS Access database and data entry forms (interfaces) that are very similar to the five questionnaires, which will be used by the Baseline Consultants to capture all the data on the administered questionnaires.
The Baseline consultants shall submit field data and maps (field returns) on CDs in MS Access and ArcView respectively. These data shall then be processed, analyzed and upsized to Oracle format to produce the National Water Supply and Sanitation Database by the MIS Consultant.
The Baseline Consultants shall use five forms to capture all the relevant data on water supply and sanitation and the water related diseases. While the administrators are using the questionnaires to extract data from the respondents, the GIS field officer will be geo-referencing the locations of water and sanitation facilities by reading the coordinates of such locations with hand held GPS instrument of any brand or make with 3 - 5 meters precision.
The recommended GIS software for this project is ArcView or ArcGIS and the digital maps must be in ArcView readable and JPEG format. Project files will be created for states, layouts and view for LGA. The symbols and colour codes to be used to represent promoters of water supply and sanitation facilities .e.g. well, boreholes and water plants on the map shall be as follows:
