Nearly one third of the households had never attended formal education and 51.6% of them were at primary level. Over 45% were farmers. These lower formal educational levels might influence the sanitation awareness of the respondents although other sources of knowledge are there. Educational status were significantly associated with use of improved water source and sanitation [8, 2]. Individuals with High school completed or above educational level demonstrated better latrine utilization than those without formal education [12]. Possession of Larger family size (5 and above by 40.2% of the households) could increase the time and energy expend to fetch water and the magnitude of open defecation when latrine and pure water coverage is low as revealed in the current study.
Latrine coverage of the town varied among its zones, being lower in Eastern zone. The overall latrine coverage of the town (45.3%) was lower than those reported for Dukem town (70.1%; [18]), Wolaita Sodo town (91%; [8]), for Ilu Aba Bor Zone (88.2%; [13]) and the overall Oromia region (72.7%; [14]) in which Negele town is found. This difference might be due to factors like variation in awareness and economic status of the people among others.
Besides lower coverage, most of the existing latrines (64.5%) were closer than the minimum recommended distance (6m) from a kitchen according to [4]. So, it is easy for bad odour to reach houses and for flies to carry pathogens to the kitchen where food is prepared and kept. Similarly, about 76% respondents from Nepal indicated latrine distances from their homes were less than 6m [15]. The absence of latrine roof (52.3%), door (53%) and hole cover (100%) promotes the invasion and breeding of flies which spread diseases. Moreover, latrines may be filled during rainy seasons and discharged to the environment posing human health and environmental sanitation problems. Lack of cleaning water not only enhances bad odor to reach homes but also hand washing activity after using toilet. Lack of sewerage service had forced the households either to dig new toilets (70%) or drain to the environment (30%) (Table 3) that could lead to economic constraints and environmental pollution. Perception of their latrine as clean, standardized and good for health (by 3.5% of the households) in the absence of water for cleaning could be due the household’s lack of good knowledge of sanitation implying the need to raise public awareness and provide technical assistance in building latrines. In similar study, [16] reported the presence of laterine hole cover in 47.6 % of the latrines in Dembia town, northwestern Ethiopia and [10] reported that 13% of the respondents were using improved latrine in Chiro Zuria Woreda, eastern Ethiopia
Lack of enough land and money was raised as the main factor that hindered the households from having their own latrine letting them defecate in various sites of the environment including open fields , in bush and house compound as there was no alternative like public toilet. This influences environmental sanitation, human health and psychology [17]. The administration of the town and other concerned bodies should target provision of land, searching for fund and building public toilet to improve the latrine coverage of the town. Moreover, public awareness creation and mobilization should be given due attention as 67% and 50% of latrine lacking households expressed that they had no plan and did not get advice, respectively to build latrine. [16] indicated that 88.6% of the respondents who had latrines were advised to construct latrine by health extension or community health agent personnels in a northwestern Ethiopian town, Dembia.
The coverage of pure water (7.64%) of the town was low compared to other towns like Dukem (98.5%; [18]) and Wolaita Sodo town (68%; [8]) forcing most of the households to use unprotected Nano River without heat or chemical treatment and to suffer from waterborne diseases. Even [19] reported a 70% access to improved water of various sources (hand dug well, developed spring and rope pump ) for a rural district in western Ethiopia. This shows the need to act immediately by the concerned bodies to expand pure water supply, and create awareness of the community to boil or treat the water using chemicals used to treat water in Ethiopia like “Wuha agar (chlorine-based water treatment solution ) or Bishan gari (aluminum sulphate and calcium hypochlorite),
The responses of the key informants supported that of households regarding lack of public toilet, presence of widespread open defection and its consequences, and shortage of pure water. However, most of the key informants raised low involvement of administration and residents’ awareness/attitude related issues in contrast to the households’ land and money shortage as major factors for low coverage of latrine.
The key informants enumerated non-functioning public pipes, low involvement of the administration, inadequate amount water from the source and lack of storage tanker as contributing factors to low water coverage of the town. This implies that the water coverage of the town can be partly improved through pipe maintenance, drawing the attention of the town’s administration and establish water storage facility.
The administration of the town raised shortage of water from the source and widespread illegal houses as the main factors against pure water and latrine coverage of the town, respectively. It was interesting that the administration of the town had planned to improve pure water coverage to 70% through establishing water storage tankers and public pipes, and improve latrine coverage via building four public toilets in the town by 2018/2019. However, the administration should also employ reliable alternative water resource like ground water to solve shortage water and achieve the country’s target of providing-safe water to 100% city dwellers by 2020 [20] Moreover, building four public toilets is not expected to solve the toilet shortage of the town so that public awareness creation and mobilization and provision of necessary assistance to build their own toilet should be given due attention.
Observational survey by the investigators supported the households’ and key informants’ data .It was founded that most of the households lack latrine and even the existing latrines were open to the environment, built from non-durable materials. As the latrines have not been connected to sewerage system, all need to be abandoned once became full leading to land or money constrains, and defecations in the environment. The few available private taps were also featured by infrequent and insufficient water worsening the pure water coverage of the town. Generally, the pure water and latrine coverage of the town was found to much lower than the national Millennium Development Goal (MDG) targeting which targeted a 100% improved hygiene and sanitation to be achieved by 2015 [21] though the country managed to improve sanitation coverage from just 8% (1990) to 71% (2015) and reduce open defecation from 44.3 million (1990) to 28.3 million (2015) [14]
