Wastewater Treatment Operations for our Facility

There were two wastewater treatment plants serving the Town up till 2003.  The municipal secondary treatment facility serves the Town's CBD, most of the surrounding residential areas as well as the Guild area.  This plant was built in 1971 as a primary treatment facility designed to treat 1.3 MGD of flow.  It was upgraded in 1988 to a secondary aerated lagoon system with the design flow remaining unchanged.  Since that time it has been upgraded and modernized so that we were able to eliminate our chlorine disinfection system with Ultra-violet light disinfection. New fine screen trash removal equipment on the headworks was installed as well as an energy efficient fine bubble aeration system in our treatment lagoons.

The second treatment facility in Town was a large lagoon system that was built in 1971 in the Guild area behind the Dorr Woolen mills. The system was built exclusively for the treatment of the industrial discharge from the woolen mill. The lagoons were used up until the mill closed down in 2003.  Since that time they have laid dormant only taking in runoff and storm flow. It is anticipated that they will be dewatered and the sludge removed from them in 2007, with the lagoons themselves being breached so that they will no longer retain water.

The average daily flow through the municipal plant is 720,000 gallon per day.  Many or our sewer mains are extremely old and susceptible to high levels of inflow/infiltration (I/I). This results in an unnecessary overload to the plant, increasing the expense of the operation. While there has been much work done throughout the Town in recent years to replace and upgrade the water and sewer lines reducing the amount of I/I coming to the plant, there is still much more work that needs to be done.  

Septage Receiving and Treatment for our Facility

In April 1988 The TOWN OF NEWPORT WWTF implemented the conditions of our Consent Decree, in anticipation of the startup of the new secondary treatment facility. Dramatic changes were made in how we accepted and controlled the discharge of septage into our facilities.  The most important change made was that we were no longer taking any septage from other Towns; it would only be taken from Newport residents.  The Homeowner is now required to pick up a two-part permit which can be obtained at the Town Office. They retain one part of the permit which they give to the hauler when he pumps the homeowner's septic tank. The septage is brought to the plant during specific hours, logged in at the plant-noting the source and then discharged into a tank designed to specifically handle and treat the waste.  Lastly, the haulers are charged a fee equivalent to what it costs us to treat, process and dispose of the septage as well as the sludge generated by it.

This change in operations brought the septage disposal problem under control immediately. It eliminated the discharge violations by bringing the flow of it down to a more manageable level and allowed for the septage to receive proper treatment.  We have seen our septage flows go from a high of over 263,000 gallons a year to less than 122,000 gallons in 2005.  With the increased buildup in the outlying unsewered areas we will begin to see that flow numbers rise proportionately in the coming years.  This increase will put a strain on our continued ability to properly handle the septage, resulting in increased fees and expense to the plant to dispose of the additional material.

SEWAGE TREATMENT

TO FIRST UNDERSTAND SEWAGE TREATMENT (WATER POLLUTION CONTROL, WASTEWATER TREATMENT, ETC.) WE FIRST NEED TO KNOW A LITTLE ABOUT WHAT SEWAGE IS, WHAT IT CONTAINS AND WHAT ITS HARMFUL EFFECTS ARE.

1. SEWAGE CONTAINS ABOUT 99% WATER AND 1% SOLID MATERIAL,

  THE WATER IS THE METHOD OF TRANSPORTING THE SOLID MATERIAL TO WHERE IT CAN BE TREATED.

2. IF SEWAGE IS NOT TREATED IT CAN:

  A. CAUSE DISEASE;

     1. DIARRHEA

     2. DYSENTERY

     3. CHOLERA

     4. TYPHOID

  B. CREATE BAD ODORS AND VISIBLE CONTAMINATION

  C. USES UP DISSOLVED OXYGEN IN RIVERS, LAKES & OCEANS THAT AQUATIC ANIMALS REQUIRE

  D. KILLS ANIMALS, BIRDS, FISH AND OTHER WATER LIFE

  E. IT COULD END UP CONTAMINATING DRINKING WATER SUPPLIES

3. SEWAGE MAY CONTAIN ANY OR ALL OF THE FOLLOWING POLLUTANTS:

  A. OXYGENDEMANDING WASTES

  B. DISEASE CAUSING AGENTS

  C. NUTRIENTS

  D. SYNTHETIC ORGANIC CHEMICALS

  E. INORGANIC CHEMICALS & MINERALS

  F. HEAT

  G. SEDIMENT/SILT

  H. RADIOACTIVE SUBSTANCES

4. POLLUTANTS CAN COME FROM:

  A. HOMES

     1. IMPROPER DISPOSAL OF HOUSEHOLD HAZARDOUS CHEMICALS, PAINTS, SOLVENTS, MOTOR OIL, OLD MEDICATIONS, PERSONAL CARE PRODUCTS, ETC.

  B. INDUSTRIAL/COMMERCIAL SOURCES

      

     1. FACTORIES, MINES, REFINERIES, POWER PLANTS, SERVICE STATIONS, LAUNDROMATS, RESTAURANTS, ETC.

  C. FARMS

     1. FERTILIZERS, ANIMALS, INSECTICIDES, ETC.

     2. LARGE CONTRIBUTORS OF NONPOINT SOURCE POLLUTION W/MANURE RUNOFF.

  D. AIR

      

      1. WHEN IT RAINS IT CAUSES AIR POLLUTANTS/NUTRIENTS TO RETURN TO THE GROUND, RIVERS, LAKES, ETC.

   E. WILDLIFE

   

      1. ANIMALS, BIRDS, ETC.

      2. ALLOWING GRAZING CATTLE, HORSES, ETC. TO HAVE STANDING ACCESS TO RIVERS AND STREAMS.

5. SEWAGE TREATMENT PLANTS SPEED UP THE NATURAL PROCESSES BY WHICH WATER PURIFIES ITSELF, USING PIPES, TANKS, SCREENS

   AND OTHER PROCESSES BY DIRECTING THE FLOW OF SEWAGE TO THE RIGHT PROCESS AT THE RIGHT TIME.

   YEARS AGO BEFORE THE TREMENDOUS GROWTH IN POPULATION, IT WAS FELT THAT NATURE WOULD CLEAN THE FAST MOVING BODIES OF WATER, LIKE THE SUGAR     

   RIVER, WITHOUT THE HELP OF MAN. AN OLD POPULAR SAYING IN THE SANITARY ENGINEERING FIELD WAS "THE SOLUTION TO POLLUTION LIES IN ITS DILUTION".

   NOW TODAY WITH A GREATLY INCREASED POPULATION, MAN MUST ASSIST NATURE, FOR OBVIOUS REASONS.

6. THERE ARE TWO MAJOR TYPES OF TREATMENT PLANTS.

  A. BIOLOGICAL PLANTS WHERE THE BACTERIA WITHIN THE SEWAGE USES UP OR CONSUMES OTHER BACTERIA. (NEWPORT'S SYSTEM)

  B. PHYSICAL CHEMICAL PLANTS WHERE CHEMICALS ARE USED TO HELP SETTLE OUT THE BACTERIA AND OTHER HARMFUL CHEMICALS AND/OR MATERIALS IN THE   

      SEWAGE.

7. THERE ARE THREE MAIN STAGES OF TREATMENT VARIATIONS EXIST

  A. PRIMARY USED IN NEWPORT

     1. SCREENS OUT OR GRINDS UP COARSE MATERIALS SUCH AS RAGS, STICKS, STONES, ETC.

     2. REMOVES GRIT, SAND, SMALL STONES, ETC.

     3. REMOVES SOME SETTLEABLE SOLIDS AND FLOATING SCUM

  B. SECONDARY USED IN NEWPORT

     1. BACTERIA AND AIR ARE MIXED TOGETHER IN THE CORRECT AMOUNTS TO USE UP OR CONSUME THE DISSOLVED AND SUSPENDED MATTER THAT CAN NOT BE REMOVED IN THE PRIMARY STAGE.

     2. ADDITIONAL SETTLEABLE SOLIDS ARE REMOVED AND IN SOME INSTANCES, NUTRIENTS ARE REDUCED &/OR REMOVED

  C. DISINFECTION  USED IN NEWPORT

     1. USE OF ULTRAVIOLET DISINFECTION, TO ACHIEVE A PATHOGEN KILL, WATER PASSES AT CLOSE RANGE THROUGH BANKS OF ILLUMINATED UV BULBS.

     2. THERE ARE SEVERAL OTHER TYPES OF DISINFECTION AVAILABLE SUCH AS CHLORINE GAS, HYPOCHLORITE, OZONE

LEAF DISPOSAL

The treatment plant will accept leaves from all Town residents at anytime throughout the year.  We prefer that you bring them down in paper bags or in bulk. We will accept them in plastic, but we ask that you please empty them out at the compost pile and you can either take the bags back with you or drop them off in our dumpster at the main control building.  We also ask that you please only bring in leaves, green waste, grass clippings and miscellaneous small brush when you are loading the bags. We do not want any household trash or garbage in the bags when they are left here for disposal, there are dumpsters for that type of waste.  Please do not ruin the privilege for others.  

Please call the plant at 863-4338 before you plan on coming down to drop them off, while we have regular hours we can be offsite or at a class and the compost pile would not be accessible to the public for disposal.  

There is no charge for this privilege, we just ask that you empty out your plastic bags and please do not leave us with your trash. 

TOURS

We are located on Putnam Road, which is across the road from the High School on Route 10 North.  We are more than happy to give anyone who is interested a tour of our facility, especially school groups from any area school that might be interested in learning about wastewater treatment. We just ask that you call 603.863.4338 5-7 days in advance of your planned visit to be sure that an operator will be at the facility and that we will be able to accommodate your request, occasionally we are working on projects that preclude us from allowing visitors onsite due to safety concerns.
