Hamilton Township Mayor Jeff Martin and Robbinsville Township Mayor Dave Fried jointly announced today that both municipalities deem it necessary to raise residential and commercial sewer rates for the first time in over a decade. The Hamilton Township wastewater facility is in dire need of infrastructure upgrades, officials said.

Hamilton and Robbinsville, which have two of the lowest sewer rates in all of Mercer County, have agreed to share the cost of a rate study. Following a comprehensive review by each township, residential sewer rates in each municipality will increase effective in July and reflected on the Oct. 1 bill. For Robbinsville residents, the proposed increase is $85 per-household for a total annual cost of $425. For Hamilton residents, the increase would amount to $78 per-household to $390. Non-residential rates in both towns also will be adjusted.

Previously, Hamilton and Robbinsville mutually agreed to dismiss a pending lawsuit regarding past sewer payments without prejudice. Both sides continue to work on reaching a long-term settlement, without the cost of attorneys, in another step toward fostering continued good relations between the neighboring townships.

Every utility is required to file financial reports annually to the State of New Jersey by Feb. 10 of each year.  As part of this reporting, a calculation done to ensure the utility is solvent, known as “self-liquidating.”  It is important to maintain a self-liquidating status in order not to impede or effect municipal operations, officials said.

The municipalities will rely on that data upon completion of the rate study to establish future shared costs.

In an April 2018 wastewater utility financial survey conducted by the Hamilton Township Water Pollution Control, the total annual cost of a residential family of four in neighboring municipalities in Mercer and Burlington Counties ranged between $600-900. The proposed increase must be presented and approved by each municipality’s governing body. Such approvals still would result in a revised average household sewer bill below the rate of neighboring municipalities.

Hamilton Township last raised its sewer rate in 2008. Robbinsville has raised sewer rates just once, in 2011, since 1990.

“Both towns are equally committed to running the sewer utility in a responsible manner that accommodates the needs of both townships fairly,” Fried said. “The previous administration in Hamilton used all of its surplus and one-time revenue, among other gimmicks, to avoid this inevitability. We know how important this infrastructure is to the residents and businesses of Hamilton and Robbinsville. This is also a health and safety issue with no room for politics. While no one likes a rate increase, especially amid a pandemic, this is the only action that will ensure the facility is highly functional and properly run while we await the conclusion of the rate study.”

“We have a plant that is very well run and could not survive any longer at its current rates without jeopardizing its operations,” Martin said. “Under the new rate, each Hamilton residential ratepayer would only spend $1.07 per day for their sewer service.  This increase will solidify the utility’s financial position to ensure continued and uninterrupted service for our residents.  Hamilton has seen what happens when a township neglects a utility and I cannot permit that to happen here in Hamilton.”

Hamilton operates a regional wastewater treatment facility serving residents of both Hamilton and Robbinsville. The sewage is ultimately treated at Hamilton’s Water Pollution Control plant before being discharged into Crosswicks Creek. Hamilton and Robbinsville have had a joint sewer agreement since 1976.
