Houston City Council approved an $8.5 million plan Wednesday to replace some of the oldest water meters in the city.

KPRC 2 Investigates has exposed systemic meter reading and water billing issues at the city of Houston's water department for the past 2 years. Just this month, the water department used ordinance changes City Council approved in December to wipe out hundreds of high balances.

KPRC 2 Investigates has received a flood of complaints against the city of Houston water department. Customers are calling us when they receive abnormally high, astronomical bills that they believe must be the result of a mistake or billing error. They say their calls and emails to the city go unanswered or drag on for months without resolution.
