City crews will flush water mains in Clear Lake next week, which may cause some changes in service for residents.
    The flushing of the hydrants will begin Monday, Oct. 1, and continue through Friday, Oct. 5.  
    The water is safe to drink, but people may note some discoloration.  The discoloration may affect laundry.  People may also notice a loss of pressure at some times.  The crews will be starting in the middle of the city and working outward.
