Our technicians are available 24 hours a day and 7 days a week to accommodate our customers in case of an emergency. Don’t know where your septic tank is?

Cover extensions

Septic tank extensions are recommended on tanks that are 12 or more inches deep. They are essentially a sleeve installed over the septic tank cover to bring access closer to ground level. The covers are green to blend in with the lawn or can be placed just below grade. There are several benefits of a cover extension such as, less landscape disturbance, easy to locate tank cover, easy access especially after the New Hampshire frost sets in for the winter. Usually at the time of pumping a technician will evaluate the need for a cover extension. At that time he will also quote a price, which is determined by the depth of your septic tank.
