The Brookfield Water Pollution Control Authority is cautioning customers that the June 1 Sewer Use bill includes a rate increase. This is the first Use Rate increase since June 2017, and even though the rate is going up, rates are still below state average. The Authority is also reminding sewer use customers that flushable wipes are not flushable and must be thrown in the garbage. These wipes do not break down when disposed of in the toilet or septic system. Clogged pipes in household plumbing and the sewer collection system are costly and result in sewer backups.
