3. About Riverdale Water Company
 Northbridge-based Riverdale Water Company, LLC was formed in
2003 to engage in the distribution and sale of water for drinking,
domestic and industrial purposes, and the protection against fire in
within the Town of Northbridge
 Riverdale Water Company was founded in 2000 with the purchase
of a 47-acre parcel located off Quaker St.

excellent aquifer material was protected by an overlying clay layer
 RWC currently sells water to bulk water haulers who use it for
swimming pools and cooling water for power plants

4. Town of Northbridge: Current Situation
Excessive levels of iron in
the brain have been linked
Two Piping Systems
 Whitinsville Water Company (WWC) to Alzheimer's and
owned and Town of Northbridge owned Parkinson’s disease
 2,234 households are served by the
Northbridge system
Northbridge’s Current Water Supply, provided by
WWC, Contains Levels of Iron and Manganese
That Sometimes Exceed The National Secondary
Maximum Contaminant Levels
 Undesirable aesthetics
 Damage to water handling equipment
WWC’s supply, influenced by surface water, must
be treated, driving up cost for Northbridge
residents
 WWC, in a report to the Department of
Public Utilities projected the construction Certain populations should
cost of the now operational water not ingest more than 0.3
treatment plant to be $5.9 M mg/L of manganese for
greater than 10 consecutive
days

5. Town of Northbridge: Current Situation
No Secondary Source of Water in Case of Emergency
Wasting Water
 30% of water pumped through the Northbridge system is being
wasted because of leaking, inefficient water pipes
 One of the highest unaccounted-for-water percentage in the
state
 MassDep recommends that unaccounted-for-water should be
10% or lower

6. Solution: It’s All About the Water
RWC has developed, permitted and constructed a new source of water
at no capital cost to Northbridge
 More than $1.1 M has been spent to develop the source and
build a pumping station
Since our last meeting…
 Completed two pumping wells
 Built a pumping station that will be operable in March

7. Solution: It’s All About the Water
RWC’s source is unique as it has no iron
or manganese
 The concentration of iron found
in WWC’s water supply ranges
from 0-2 mg/L and the
concentration for manganese
ranges from 0-0.36 mg/L
RWC’s aquifer, at 90 to 124 feet below
ground, is protected by a thick layer of
silt and clay, ensuring no surface water
is able to cause contamination
RWC has the ability to supply 277 million
gallons per year
 Town purchased 191 million
gallons wholesale from WWC in
2009

8. Why Is This Important to Northbridge?
Health
 Residents of Northbridge will receive healthy, quality water free of iron and
manganese
Aesthetics
 Northbridge’s water supply will not cause damage to property coming into
contact with water
Emergency Preparedness
 With a secondary supplier such as RWC, Northbridge will be prepared in
case of drought or other emergencies

drought-season approaches

9. Why Is This Important to Northbridge?
Economic
 Leaking, inefficient pipes will be replaced as RWC stands ready to
apply for Federal and/or State grants to upgrade pipes
 By conserving water, excess water would be available to sell to
adjacent towns, generating revenue for Northbridge
 Estimated $150,000 to $260,000 in revenue based on water
saved by repaired pipes
 Potential reduction in water costs for residents and businesses
connected to Northbridge pipes
