Photo / NZME Treat Lake Tarawera the same as other sewerage reticulation schemes, and if not, explain why you can't. That's the message from Rotorua MP Todd McClay to Rotorua Lakes Council on its proposal to charge Lake Tarawera residents an uncapped $33,000 lump sum for sewerage reticulation. McClay wrote to Mayor Steve Chadwick calling on the council to give residents the option to pay the sum off over time. "Previous schemes implemented by [the] council have been paid for by users contributing each year in addition to their rates bill," he wrote to Chadwick on April 30.
