Wastewater Home Owners Information


Dear homeowner:

Thank you for visiting our site. Choosing a wastewater treatment system for your home is a huge decision and you should seek professional advice from an engineer or architect before making a final decision.

One of the first steps toward choosing a system is to get yourself informed. You have taken the first step by coming to this page. I encourage you to do your research, check out other systems and ask questions. Don’t be afraid to pick up the phone and call us or send us an email. We are glad to help you through the process whether it is for choosing a system, seeking grant funding or getting help servicing your equipment Roman Stone is here to help you through the process.

Below you will see some photos showing installations from several different sites on Long Island. We want you to realize that your yard will be dug up and that some restoration work will have to be done either by you or a professional landscaper. Grass will grow back but hardscaping, trees, gardens, sprinkler systems might get damaged.

The second thing you should see from the photos is that there will be big pieces of equipment in your yard and we will be digging a giant hole. The Singulair tank has one of the smallest footprints (9’3”long  x 5’6” wide x 6’ tall ) of any I/A system but it still weighs 12,000 pounds and is built to last longer than the lifetime of your home. When it comes to heavy duty construction materials, concrete is your best choice. It is less buoyant, stronger and our tanks are manufactured here on Long Island by people who live and work on Long Island just like you.

The third thing you should see is that once the installation is completed you will have at least three covers to grade on your lawn. These covers must not be buried as the system requires maintenance and the covers have to be removed to access the blower and filters below. Wonderful things can be done with your landscaping but you must leave access to the lids.

The last thing to take from these photos is that every I/A system has electrical components that runs on electricity and like anything mechanical can fail and need to be repaired or replaced. But the Norweco Singulair only has the one mechanical aerator component. It has been designed to last a really long time and of most importance to you is that even without the aerator, the system will act like a regular septic tank that is gravity fed. So even if you lose power or the aerator stops working the system will still remove the waste form your home. Once the motor is repaired or the power restored the denitrifying of the wastewater will commence like normal.

Now here is the sales pitch on why you should choose Norweco and Roman Stone.
