Water and Sanitation Agency (WASA) has suggested 25 percent increase in charges of water bills for over 5 marla houses and commercial consumers. According to sources, the consumers of 5-marla houses are being exempted from that increment while water bills of educational institutions are being reduced. Sources further said that the proposal would be given in meeting of RDA. According to officials of WASA, the authority is facing immense financial difficulties due to 50 percent raise in employees' salaries, increased in electricity tariff and no grant is being provided to the authority from the government.
