My Digambar Nagar move-in: Water ka rona shuru ho gaya

Just got possession of my 2BHK in Digambar Nagar last month. Builder ne toh bola tha municipal water aayega proper connection, but abhi mostly tanker pe hi depend karna pad raha hai. Samajh nahi aa raha daily itna tanker ka bill kaise manage hoga. Yeh hidden cost toh kisi ne bataya hi nahi, matlab brochure mein kuch aur tha. Is this normal for Digambar Nagar? Ya sirf mere society mein problem hai? Baaki log kaise manage kar rahe ho? Koi long-term solution hai iska, ya RWA ko push karna padega?
