Assalamu alaikom.
I work for a water company. My role is to develop computer systems which show where the sewage flows in the pipes. My colleagues use these systems to see if the sewage will enter cities, rivers, habitats but also water where people swim (lakes or beaches). Since public swimming is filled with haram (awrah uncovered, free mixing), does this mean I am sinful for developing the computer systems which are used to see where spilling occurs to reduce it?
