The recycling centre at Wollaston could be shut to save money.
And changes could be made to the opening hours at the remaining nine sites.
As part of last year’s budget-setting process, the county council’s cabinet agreed to review the household waste recycling centre (HWRC) service to deliver £1m of savings over four years.
A plan has been drawn up as to how the service could work, following an evaluation of the HWRC provision, and the public are being asked for their views.
Proposals include closing the site at Wollaston, one of 10 centres run by the council, as well as changing the number of days sites are open and revising opening hours.
The closure of the Wollaston site has been suggested to help the county council save money.
The site receives fewer users and less waste each year than the other nine sites but costs a similar amount to run.
Additionally, Wollaston is well served by three nearby sites, including the newly redeveloped one at Rushden.
Cllr Michael Clarke, county council cabinet member for transport, highways and environment, said: “Despite making significant savings over the past few years there are still tremendous pressures on the county council to make efficiencies.
“Our household waste recycling centres are a very important service, providing hubs where people can take their waste and recycling.
“However for the service to be able to continue we need to make changes.
“We know we have to close one site, and shutting the Wollaston one makes most sense as residents have a choice of three others within five miles.
“We also know that we have to reduce the number of days all sites are open to five but we are asking people to guide us, which days suit them best.
“To save money we also need to reduce opening hours and once again, we need suggestions as to which hours are best for the majority.”
People have until October 31 to complete a questionnaire about the proposals.
The survey is available online and leaflets are being distributed at the 10 sites alerting people to the online survey.
It is hoped changes would be implemented from February 1, 2015, subject to the approval of the council county’s cabinet committee.
