Recent data is required in our bid to tackle this menace effectively. This study aimed to provide data on the status of household WASH facilities in a remote village in Southwestern Nigeria. The survey was cross-sectional in design, and total sampling was used to select 70 household respondents. Data were obtained via observational checklists, questionnaire, and key informant interview guide. Data was entered and analyzed using SPSS 20. Descriptive statistics like measures of frequency and proportions were used. The respondents had a mean age of 43.1 ± 16.4 years, only 2.9% had tertiary education. The village had two handpump boreholes provided by the Water Supply and Sanitation Sector Reform Programme (WSSSRP)-II. All the respondents reported that the boreholes were their primary drinking water source, and water was available all through the year...

Descriptive statistics like measures of frequency and proportions were used. The respondents had a mean age of 43.1 ± 16.4 years, only 2.9% had tertiary education. The village had two handpump boreholes provided by the Water Supply and Sanitation Sector Reform Programme (WSSSRP)-II. All the respondents reported that the boreholes were their primary drinking water source, and water was available all through the year. In over 80% of households, females were assigned the duty to fetch water, while most households had the boreholes within 30 minutes from their houses. The sanitation facilities were also provided via the WSSSRP-II. The majority (90%) of the respondents owned pit latrine with slab, of which only 10% shared their facilities with other households. Most (95.7%) of the respondents still practised open defecation at instances they could not access their household latrines. All the toilets had water for handwashing, and the soap commonly used by community members was palm kernel ash. The condition of water and sanitation in the village was quite progressive. However, subsequent interventions should ensure toilet facilities are available in non-household settings like farms and markets.

The coagulation efficiency of AS and composite AS and polydimethyldiallylammonium chloride (AS/PDMDAAC) coagulants were investigated using jar test and then, coupled with rapid sand filtration (RSF). The various composite AS/PDMDAAC at different intrinsic viscosity of PDMDAAC and mass ratio of PDMDAAC to AS in coagulant solutions were optimized and operated at same supernatant turbidity (SST) or same dosage mode (SD). The results showed about 7 – 10 % reduction in dosage for all composite AS/PDMDAAC and also improved water qualities compared to AS only. The patterns of water quality improvements at lower (0.65 dL/g), medium (1.60 dL/g), and higher (2.60 dL/g) intrinsic viscosity of cationic polymer PDMDAAC among different mass ratio of PDMDAAC to AS in the composite mixtures were 5:1 > 20:1 > 10:1; 10:1 5:1 > 20:1; 20:1 > 10:1 > 5:1 respectively. The percentage removal efficiencies for AS and optimal composite coagulant at intrinsic viscosity (1.60 dL/g) and mass ratio (10:1) operated at SST or SD after filtration for CODMn, NH3N and turbidity were (71.20, 72.72, 73.33 %); (69.15, 69.23, 73.08 %) and (93.89, 95.07, 97.26 %) respectively. It was concluded that enhanced composite AS/PDMDAAC coagulants operated at SST mode showed significant water quality improvement than conventional AS having 7 % and 31.8 % for COD and NH3N removal while operational mode at SD produced more significant water quality improvements than conventional AS with 9.49 %, 45.45 %, and 39.55 % for COD, NH3N, and turbidity removal before filtration respectively. More importantly, all-composite AS/PDMDAAC met stringent water quality requirements before and after filtration. This research provided new insight about the application of economical and effective alternative composite AS/PDMDAAC coagulant useful in the treatment of water for a large population.
