MACHIAS WASTEWATER TREATMENT FACILITY 2016
The Town of Machias’ Wastewater Treatment Facility consists of eight miles of sewer collection system piping, one inverted siphon station, two pumping stations and a treatment facility with the capacity to treat an average of 900,000 gallons of wastewater per day.
As we reflect on the past year, we want to personally thank the residents of the Town for all they have done, not only by supporting wastewater personnel in their jobs, but also by giving us the tools we need to do our job effectively. Through your actions, you have proven your commitment and respect for the environment. We would invite anyone interested in touring the facility to please call us at the Machias Treatment Facility, and we would gladly show you around, as well as explain how the process works.
2016 WASTEWATER TREATMENT FACILITY REVIEW
Process treatment summary:
73,800,000 gallons of wastewater was treated at the facility.
Effluent Biochemical Oxygen Demand (BOD) averaged 4.6 mg/l with a removal rate of 99%.
Effluent Total Suspended Solids (TSS) levels averaged 5.8 mg/l with a removal rate of 99%.
The licensed TSS and BOD monthly average limitations are 30 mg/l with a minimum removal rate of 85%.
Collection system progress:
A lot of work was completed within the collection system over the past year. Two manholes were raised on Court St. to bring them up to grade with the road. The wastewater crew, with the assistance of the fire department, cleaned and flushed the sewer lines and manholes on Stackpole Road, Harwood Street, Salem Street, Bedford Street, Fremont Street, Dublin Hill, Grove Street and the East and West-side cross-country lines to the siphon. This is very important to prevent sewer back up events.
Inspected cross-country lines from West Street to Water Street and Cooper Street to the treatment facility. The siphon station was cleaned and the three lines that run under the Machias River were flushed twice.
Manholes were raised on Center St., Bowker St., Bruce St., Cooper St., Water St. and Prescott St. to bring them flush with the new pavement.
Wastewater Treatment Facility:
The wastewater staff spent a lot of time in 2016 completing housekeeping and maintenance to improve the overall appearance of the plant. This work included the following key items:
- All three clarifiers were drained and cleaned and pressure washed. New squeegees and flush arm gaskets were installed. Also, a motor for one of the clarifier drives was replaced.
- Both aeration tanks, digester, wasting tank, contact chamber and conditioning tank were drained and cleaned. The amount of debris that was removed from these tanks was significantly less than last year due to regular cleaning and maintenance.
- Rebuilt High Tide Actuator Valve internal parts and replaced electronics.
- Replaced magnetic motor starter on grit pump.
- Replaced clarifier drive motor.
- Replaced fencing that was torn down and damaged around the plant.
- Patched the roof due to minor leaks.
- Completed new maintenance and collection system plans.
- Installed kick plates around all aeration tanks.
The Town of Machias Wastewater Staff is requesting your assistance to prevent blockages in sewage infrastructure, pipes and pump stations, resulting from improper disposal of consumer products. Preventing blockages by disposing of these products properly will prevent inconvenience to users of the system, caused by backups, avoid increased cost of maintenance operations and help prevent violations of our discharge permits. Examples of the consumer materials that can cause sewer blockages when disposed of in sewers include the following: – Baby/disinfecting wipes – Disposable toilet cleaning pads – Moist towelettes – Makeup removal pads – Disposable mop heads – Dental floss – Surface cleaning wipes – Candy wrappers – Towels. While many of these products are marketed as “flushable”, several studies, and the experience of utilities across the country, have shown that they do not break down after disposal like common toilet tissue. The synthetic fibers that make the wipes and other products strong and effective can cause them to form clumps that easily entangle in pumps without ripping. Sewage can back up behind these clogs, sometimes causing wastewater to discharge into homeowner basements. These products should be disposed of in the trash.
The wastewater treatment industry is working with the manufacturers of these products to provide more accurate labeling, to define the term “flushable”, and to ensure that products are disposed of in a responsible way. Additional consumer items that may be labeled as “disposable”- such as diapers, feminine hygiene products, bladder control undergarments, plastic bags, and fabric cloths- should never be flushed. None of the products listed above should be disposed of in sewer or storm drain systems. Your cooperation in disposing of these wastes properly will protect not only your local surface waters but also your bottom line by reducing the need for tax increases to fund expanding maintenance requirements.
Please contact me at 255-3295 if you have any questions.
In closing, we would like to thank the Board of Selectmen, Town Manager and the Highway crew for helping to keep the wastewater infrastructure in top condition. Again, we would also like to thank the taxpayers for their support, because without your help, it would be extremely difficult to keep our Town and the environment the way we all expect it to be.
Charles Croan, Superintendent
