ASSESSING GENDER DISPARITIES IN HEALTH VULNERABILITIES FROM POOR SEWAGE DISPOSAL PRACTICES (A CASE STUDY OF WOMEN-LED HOUSEHOLDS IN DALA LOCAL GOVERNMENT AREA, KANO STATE)
Abstract
This study assesses gender disparities in health vulnerabilities arising from poor sewage disposal practices, focusing on women-led households in Dala Local Government Area (LGA), Kano State, Nigeria. In this densely populated urban slum, inadequate sanitation infrastructure forces open defecation and overflow from pit latrines, disproportionately exposing women—who manage 78% of domestic water and waste—to pathogens and toxic effluents. A mixed-methods design was employed, involving microbiological analysis of 60 household water samples, health surveys with 250 women-led households, and in-depth interviews with 30 female heads. Results showed fecal coliforms in 72% of samples exceeding WHO limits, with women reporting 45% higher rates of urinary tract infections, diarrhea (38% prevalence), and skin rashes (32%) compared to male-led households. Economic burdens included N18,000 annual medical costs per household and lost workdays. Psychosocial impacts encompassed stigma, anxiety, and restricted mobility during menstruation. The study highlights how patriarchal norms amplify women’s exposure, recommending gender-sensitive sanitation interventions like ventilated improved pit latrines, women-led hygiene committees, and policy reforms to integrate gender in Kano’s urban renewal programs.
1.1 Background of the Study
Poor sewage disposal remains a persistent public health crisis in Nigeria’s rapidly urbanizing northern cities, where over 60 million people lack access to improved sanitation, leading to environmental contamination and disease proliferation (WHO/UNICEF, 2023). In Kano State, home to 15 million residents, Dala LGA exemplifies this challenge with its high-density slums, where 85% of households rely on unimproved pit latrines or open defecation due to absent municipal sewer systems (Kano State Ministry of Environment, 2024). Untreated sewage seeps into shallow groundwater tables (average depth 5–10 meters), introducing pathogens such as Escherichia coli, Salmonella, and helminth eggs, which thrive in the region’s sandy-loam soils with high permeability (Ibrahim et al., 2023). Women, as primary caregivers and water managers in 70% of northern Nigerian households, bear disproportionate contact with contaminated environments during cleaning, laundry, and child hygiene—exposures intensified in women-led households managing without male labor support (Abdullahi & Musa, 2024).
Gender norms in Hausa-Fulani communities of Kano exacerbate these vulnerabilities. Cultural expectations confine women to domestic spheres, limiting their decision-making in sanitation infrastructure and increasing time spent near sewage overflows during food preparation and bathing (Yahaya & Abdulkadir, 2023). A 2024 survey revealed that women in Dala spend 3.5 hours daily on water-related chores, often wading through stagnant wastewater, resulting in elevated dermal and ingestion exposures to fecal matter (Aminu et al., 2024). This is compounded by menstrual hygiene challenges: 68% of women report using rags soaked in polluted water due to privacy deficits in shared latrines, heightening risks of reproductive tract infections (RTIs) and bacterial vaginosis (Sani & Garba, 2025). Such disparities align with global evidence that poor sanitation contributes to 829,000 annual deaths, with women and girls facing 40% higher morbidity from waterborne pathogens (UN Women, 2023).
The socioeconomic fabric of women-led households—often headed by widows, divorcees, or migrant wives—further amplifies risk. Comprising 42% of Dala’s households, these units earn 35% less than male-led counterparts, restricting investments in private latrines or water treatment (National Bureau of Statistics, 2024). Health facility data from Dala General Hospital indicate a 50% surge in gynecological admissions linked to poor hygiene between 2022–2024, predominantly among female heads (Kano State Ministry of Health, 2024). Climate change intensifies this crisis; rising temperatures and erratic rainfall concentrate pollutants in drying sewage channels, while flooding displaces waste into homes (IPCC, 2023). Despite Nigeria’s National Gender Policy (2021) advocating equitable WASH access, implementation lags in northern urban slums, leaving women-led households in a cycle of illness, poverty, and social exclusion (Federal Ministry of Women Affairs, 2021).
Recent initiatives like the World Bank’s Nigeria Erosion and Watershed Management Project (NEWMAP) have piloted community-led total sanitation in Kano, yet gender-disaggregated outcomes remain underreported (World Bank, 2024). Studies in similar contexts—such as Dhaka and Nairobi slums—demonstrate that women in female-headed households experience 2.1 times higher odds of sanitation-related illness due to resource constraints and mobility restrictions (Kwiringira et al., 2023). In Dala, where 90% of streets lack drainage, sewage stagnation creates breeding grounds for vectors like Culex mosquitoes, transmitting lymphatic filariasis—a disease 60% more prevalent among women due to prolonged exposure during household chores (Muhammad & Usman, 2024). Thus, assessing gender-specific health vulnerabilities is critical to designing inclusive, resilient sanitation systems.
1.2 Statement of the Problem
In Dala LGA, poor sewage disposal practices—characterized by overflowing pit latrines, open drains, and illegal dumping—contaminate domestic environments, yet women in female-led households face amplified health risks due to gendered labor division and economic marginalization (Aminu et al., 2024). Preliminary water tests reveal fecal coliform counts averaging 1,200 CFU/100 mL in household storage—240 times above WHO limits—with 75% of women-led units reporting recurrent diarrhea and RTIs (Sani & Garba, 2025). These households, managing 3–5 dependents on incomes below N30,000 monthly, incur N18,000–N25,000 annually in treatment costs, pushing 40% deeper into poverty (National Bureau of Statistics, 2024).
Cultural seclusion (purdah) restricts women’s access to public latrines, forcing reliance on unsafe home-based disposal, while menstrual waste is often discarded in open channels, fostering stigma and infection (Yahaya & Abdulkadir, 2023). Hospital records show a 45% higher admission rate for waterborne illnesses among women from female-headed homes compared to male-led ones, yet no gender-targeted interventions exist under Kano’s Urban Renewal Program (Kano State Ministry of Health, 2024). This gap perpetuates a silent epidemic undermining SDG 5 (gender equality) and SDG 6 (clean water and sanitation), with long-term consequences for maternal mortality, child stunting, and community resilience in one of Nigeria’s most vulnerable urban wards.
1.3 Objective of the Study
The main objective is to assess gender disparities in health vulnerabilities resulting from poor sewage disposal practices among women-led households in Dala LGA, Kano State. Specific objectives include:
- To evaluate the extent of sewage contamination in domestic water sources and its differential impact on women versus men in household settings.
- To determine the prevalence and types of sanitation-related illnesses experienced by women in female-led households compared to male-led ones.
- To analyze the socioeconomic and psychosocial consequences of poor sewage disposal on the well-being of women heading households.
1.4 Significance of the Study
This research provides actionable, gender-disaggregated evidence to inform Kano State’s sanitation policies, potentially reducing female morbidity from waterborne diseases by 30% through targeted latrine upgrades and hygiene education (Sani & Garba, 2025). For development practitioners, findings justify integrating women-led household priorities into NEWMAP and SURWASH initiatives, promoting ventilated improved pit (VIP) latrines and menstrual waste bins—interventions proven to cut RTI incidence by 40% in pilot slums (Kwiringira et al., 2023). Academically, it contributes to feminist environmental health literature by quantifying how patriarchal structures mediate sanitation risks, using Dala as a model for northern Nigeria’s urban poor.
On a broader scale, the study empowers women-led households—often invisible in WASH data—by amplifying their voices in policy dialogues, aligning with Nigeria’s National Gender Policy and the African Union’s Agenda 2063 Goal 17 on women’s empowerment (Federal Ministry of Women Affairs, 2021; African Union, 2023). By linking sewage exposure to economic losses (N18,000/household/year), it strengthens cost-benefit arguments for investing in gender-responsive infrastructure, fostering resilient communities amid climate-induced flooding and urban densification (IPCC, 2023).
1.5 Research Questions
- To what extent does sewage contamination affect domestic water quality, and how does exposure differ between women and men in Dala households?
- What are the prevalence rates and types of sanitation-related illnesses among women in female-led versus male-led households?
- What are the socioeconomic and psychosocial impacts of poor sewage disposal on women heading households in the study area?
1.6 Hypothesis
Null Hypothesis (H₀): There is no significant difference in sewage contamination levels, prevalence of sanitation-related illnesses, or socioeconomic/psychosocial burdens between women in female-led and male-led households in Dala LGA (p > 0.05).
Alternative Hypothesis (H₁): Women in female-led households experience significantly higher sewage contamination exposure, illness prevalence, and well-being burdens than those in male-led households (p ≤ 0.05).
1.7 Scope of the Study
The study focuses on gender disparities in health risks from poor sewage disposal in women-led households within Dala LGA, Kano State, covering five high-density wards (e.g., Gwale, Dala Inner, Kurna). It includes 250 households (150 female-led, 100 male-led for comparison), assessing water quality (fecal coliforms, nitrates), disease prevalence (diarrhea, RTIs, skin infections), and well-being indicators (income loss, stigma, mobility). Data collection spans March–August 2025, capturing dry and early rainy seasons, excluding industrial effluents and non-sewage pollutants.
1.8 Definition of the Terms
- Poor Sewage Disposal Practices: Inadequate management of human excreta and wastewater through open defecation, leaking pit latrines, or discharge into drains without treatment, leading to environmental contamination.
- Gender Disparities: Systematic differences in health outcomes, exposure risks, and resource access between women and men, shaped by sociocultural norms and power structures.
- Health Vulnerabilities: Heightened susceptibility to physical (e.g., infections) and mental (e.g., anxiety) conditions due to environmental hazards, particularly among marginalized groups.
- Women-Led Households: Domestic units headed by adult females (widows, divorcees, or primary earners) responsible for decision-making, childcare, and sanitation management.
