Opening hours at tips and recycling centres could be cut back to save cash.
Leicestershire County Council wants to save £300,000 from the £3.9 million spent annually running 14 sites.
These are currently open seven days a week, from 8am to 8pm in the summer and 8am to 6pm in the winter.
Options include opening at 9am and/or closing at 6pm in the summer and closing at 4pm in the winter.
Sites could also shut one day a week.
Liberal Democrats said a reduction in hours would lead to more illegal tipping, which is expensive to clear up.
Oadby Liberal Democrat councillor Jeff Kaufman said: "Any saving will be negated by the cost of dealing with illegal tipping."
A survey about the changes will run on the council's website for six weeks from Monday.
Surveys will take place at the sites from July 1.
Cabinet member for waste Blake Pain said: "At a time the council has to save £100 million, we have to look at reducing opening hours."
