Irregular water supply

We the residents of SAI DEEP CHS,Sector-10,New Panvel facing lot of problem regarding water supply from CIDCO .Previously we are getting sufficient water supply to our society, but from last 8 to 10 months the water supplied is getting with very low pressure and sometimes, it doesn't came also. So that we have to use our boring water supply for drinking and other usage.
Whenever Cidco announce for no water supply for one day, it takes at least one week to normalise the supply. After it gets normalized suddenly in between it again starts with above scenario of very low pressure supply.
I don’t know why this condition always happens for sector 10 only, because on enquiry to other sector residents they don’t face such type of problem.
So, requesting to please solve this problem as early as possible.
