Abstract | Nang Han lake is the 80 km2-area natural inland reservoir situated in Sakon Nakhon Province, 650 km northeast of Bangkok, Thailand, The 1980 A.D population of 1 km strip around the lake were approximately 43,000 including 24,491 from Sakon Nakhon municipality. Four surface water treatment plants are withdrawing 1.7 x 106 m3 of the lake water annually while untreated sewage of 1.2 x 106 m3 is discharged back to the lake. According to the lake water quality study, the water quality nearshore along the municipality is relatively poorer than the others and it was greatly improved at the farther distance offshore. Generally, the lake is still usable as a public water supply source, and the proposed water supply planning is dependent on the lake, The municipal sewage characteristics were studied and the sewage treatment scheme employing waste stabilization ponds to treat both nightsoil slurry and sewage is proposed. The sanitary landfill is recommended for municipal solid waste disposal. These proposals are considered to be effective in controlling the bacterial and organic pollution to the lake as well as improving the health conditions of the people. Water supply quality study was also conducted and it was found that most waters from shallow hand dug wells were microbiologically unsafe. The questionnaire study was conducted to evaluate the baseline conditions of the rural inhabitants concerning the water supply, sanitation and health, From the results obtained, provisions of the properly constructed shallow hand dug wells and improvement of the existing unprotected ones are most appropriate for rural water supply. Water seal latrine employing pour flush toilet is also suggested for the sanitation scheme. Health education is recommended to be integrated as a part of the water supply and sanitation schemes to achieve the maximum health benefits. |
