Abstract

The purpose of this Bachelor’s Thesis was to design two dry toilet models for the households in urban and rural environments in Ho Municipality in Ghana, and to study which kind of support systems households need to obtain a latrine and properly maintain it. To provide a starting point, a standard urban and a standard rural family were defined in the study. The thesis was commissioned by Lahti Region Development LADEC ltd, which is coordinating a North-South Local Government Co-operation with Ho Municipal Assembly on behalf of City of Lahti. The results will be utilized in the ecological sanitation project implemented in Ho Municipality in Ghana. A special notice on the study was paid on the environmental health officers’ aspect. The research is based on literature analysis and environmental health officers’ interviews and results from workshops conducted for builders and officers during my practical trainee period in Ghana. The recommended model for the urban family is a compact double-vaul dry toilet. The design is durable and therefore more cost-intensive compared to the rural choice. It is advised that the environmental health officers focus dry toilet promotion in urban areas to landlords and areas where the technique is already acknowledged by schools that have dry toilets. The recommended model for the rural areas is a bucket latrine with communal composting site. The design is a low-cost latrine, with a traditional outlook built from local materials. Environmental health officers should focus the promotion work to areas where field tests, composting training or Community-led Total Sani-tation programme have been implemented. Instead of subsidies, the focus of the promotion work should be on behavioral change and motivating the dwellers. Sanitation clubs in the communities bring sustainability for the latrines and DT knowhow. Introducing dry toilet technology to households will improve the poor sanitation situation in Ho Municipality and provide better income for the households as a result of utilizing the urine and composted faeces in agriculture.; Opinnäytetyön tavoitteena oli suunnitella kuivakäymälämallit kaupungin ja maaseudun kotitalouksille ghanalaisen Ho:n kunnan olosuhteisiin ja tutkia, millaisia tukitoimia kotitaloudet tarvitsevat käymälän hankkimiseen sekä kestävään huoltoon ja ylläpitoon. Keskiverto kaupunki- ja maaseutuperhe, jolla ei ole sanitaatiotiloja, määriteltiin osana tutkimusta. Opinnäytetyön toimeksiantajana toimi Lahden Seudun Kehitys LADEC oy, joka koordinoi Lahden kaupungin ja Ho:n kunnan välistä kehitysyhteistyöhanketta. Tutkimuksen tuloksia hyödynnetään kuivakäymäläprojektissa, joka on käynnissä Hon kunnassa Ghanassa. Tutkimuksessa keskityttiin ympäristöviranomaisten näkökulmaan. Tutkimus on toteutettu kirjallisuustutkimuksena ja aineistona on käytetty alan kirjallisuutta sekä Ghanassa työharjoittelujakson aikana tehtyjä haastatteluja ja järjestettyjen työpajojen raportteja. Kaupunkilaisille suositeltu kuivakäymälämalli on kompakti, helppohoitoinen kaksi säiliöinen kuivakäymälä.…
