Bangalore Water Supply & Sewerage Board [Bwssb] — Reverse Rain water harvesting charges

Address: Vijinapura

Dear Sir/Madam
I have a newly constructed house in 2019 on a 900 square feet area. While taking bwssb connection I had applied for same. By mistake your officials updated as 1200 squarefeet in your systems. As my site does not need RWH as per current regulations, I did not do. In jul and August I got other charges for RWH. I paid the bill and also submitted application form. Now they cancelled but they are not reversing rwh charges saying it is fine. But whose fault is this to update system wrongly. Kindly look into this and reverse the charges. E-308003,
