Suggest thinking carefully about two toilets per ward (so one always available while other being cleaned / repaired) also to making sure all surfaces including lower section of walls can be cleaned easily - note enormous challenges in UK hospitals around hygiene. Some patients will have possibly highly infectious diseases... There are lots of useful references on line. Googling "pit latrine hospital ward" for instance throws up documents by both UNICEF and WHO. I am sure others will be available from IRC, WEDC, MSF etc. Finally the question does not mention whether water is available. If it is, then other solutions might be better. I would suggest focusing on hygienic latrines which are used well (big enough challenge) before exploring whether composting for agricultural (health risks and cultural practicse!!!) use is also an option.
