History: How Did We Get Here?
History
• 2006 & 2007 – Developer constructed gravity sewer system for
planned Watuppa Plantation development. Central pumping
station for development is not built.
• April – November 2011 – New developer constructed pressure
sewer system sleeved through gravity line for planned Watuppa
Plantation development.
• November 2014 – Developer began tying in homes to the sewer
line.
History
• September 2015 through December 2015—Per the intermunicipal agreement and in accordance with the original design
and plans for the system, Fall River puts sewer infrastructure in
place in Lake Avenue area to serve 50 residential units that will
flow through the Watuppa Plantations sewer infrastructure and
to TWWD’s Blackbird Court pump station.
• December 15, 2015-- Fall River notified TWWD that a flow test
that was successful through the Fall River infrastructure failed
upon reaching the Watuppa Plantations system. Test flow
bubbled up to the ground surface of the Plantation Drive
roadway shoulder.
History
• January 6, 2015--Developer locates buried manhole, raises to
grade, and makes a repair to the sewer piping.
• January 7, 2016– Watuppa sewer system subsequently fails a
second flow test by the City of Fall River.
• February 3, 2016-- City of Fall River starts giving mutual aid to
the TWWD by vacuuming the surface manholes and gravity
sewer lines.
• February 9, 2016—TWWD contracts with C & E Engineering to
investigate cause of failure and to develop a plan to repair the
sewer system.
• February 29, 2016-- C&E Engineers issues evaluation of system
failure and recommends replacing the sewer with new pressure
line as most cost effective.

Project Timeline
• Week of April 11, 2016 project begins
• 3-4 weeks for project completion
What does this mean for your property?
• TWWD will need Temporary Right of Entry to
coordinate pumping of holding tank (4 existing
connected homes)
• Sewer connection will have to be
disconnected for 2-3 weeks
• Septic hauler will come and pump tank each
day in the morning and afternoon
What does this mean for your property?
• Homeowners should limit their water use:
– Limit laundry by running no more than 1 load per day
and/or use off site laundry facilities
– Conserve water by limiting shower time, turning off water
while brushing your teeth etc.
• If the grinder pump alarm comes on and the station
needs to be pumped, the septage hauler will be on-call
as needed. The four connecting homes will be provided
with the hauler’s emergency phone number in the
event the system needs to be pumped out prior to the
normal a.m. and p.m. pumpouts.
What does this mean for your property?
• TWWD is asking builders/property owners to
have deliveries (excluding mail, UPS and small
vehicles) occur outside of the contractor’s
working hours of 7am-3:30pm.
• Contact TWWD if you have questions or to
coordinate a special situation.
