Mentally harassing senior citizen

My parents who are retired govt officers senior citizens are being troubled by the entire society for water. We live in a private colony and it's been almost more than 1.5 years here since we shifted. Here we don't have any water supply except for government tubewell, through which people get water and take turns for it day wise. As we shifted everybody had problem in alloting a new no for our family because then the day will increase . So what they did that they use to give us odd timings to fill water like 10:30 pm -12:00 am and during this time the flow of water is just nothing. So many times our parents used to call personal tanker . I used to see my parents folding and unfolding the pipe late at night nd rest everybody in the colony sleeping.The point from where we fill d water is at a distance so folding and unfolding the pipe is little difficult. My mother has knee problem and is not able to walk properly . We are two working daughters so our parents never used to involve us in this matter and has always asked us to sleep early. They didn't want to create any kind of fuss and wanted to solve the matter peacefully so they never raised their voice and tried to get a fixed no for our family . They tried to treat them, gave them money but nothing worked and now it's been so long nowadays my father is not keeping well so we children tried to raise our voice but still no solution. At times one of our neighbors bosses around and abuse my mom like anything for water only. They stand together and don't listen to us at all. Nowdays there is so much of tension going on in our house just because of this water. Not only our parents but now even we are getting mentally harassed.
