The

was

inaugurated

in

January

...

of

2007

with

that

members,

and

...

.

...

The

ceremony

...

marked

a

signficant

...

milestone

...

of

...

the

...

end

...

of

...

the

construction

...

phase,

...

but

...

it

...

wasn't

...

until

...

later

...

in

...

the

...

year

...

that

...

we

...

were

...

able

...

to

...

bring

...

the

...

plant

...

fully

...

online

...

and

...

operating

...

according

...

to

...

design.

...

The

...

first

...

year

...

of

...

plant

...

operation

...

was

...

a

...

learning

...

experience

...

for

...

everyone

...

involved

...

as

...

we

...

developed

...

operating

...

guidelines,

...

made

...

improvements

...

to

various

...

components,

...

and

learned

the

art

...

of

adjusting

the

alum

dose

...

to

...

obtain

...

clean

...

water.

...

At

...

the

...

inauguration

...

ceremony

...

we

...

committed

...

to

...

providing

...

upgrades,

...

technical

...

support,

...

and

...

whatever

...

else

...

was

...

required

...

to

...

produce

...

clear,

...

safe

...

water

...

at

...

the

...

Ojojona

...

plant.

...

Due

...

to

...

the

...

number

...

of

...

technical

...

innovations

...

required

...

to

...

build

...

and

...

operate

...

a

...

small

...

scale

...

gravity

...

powered

...

water

...

treatment

...

plant

...

it

...

took

...

an

...

additional

...

9

...

months

...

after

...

construction

...

was

...

completed

...

to

...

reach

...

that

...

goal.

...

During

...

those

...

months

...

we

...

developed

...

new

...

fabrication

...

techniques

...

for

...

modular

...

baffles

...

and

...

plate

...

settlers,

...

learned

...

the

...

importance

...

of

...

controlling

...

the

...

plant

...

flow

...

rate

...

to

...

eliminate

...

flow

...

spikes

...

after

...

rain

...

storms,

...

developed

...

a

...

much

...

simplified

...

plant

...

operating

...

procedure,

...

devised

...

maintenance

...

procedures

...

that

...

optimize

...

plant

...

performance,

and

...

designed

...

and

...

fabricated

...

the

...

next

...

generation

...

of

...

flow

...

control

...

modules.

...

The

...

result

...

is

...

a

...

water

...

treatment

...

plant

...

that

...

is

...

easy

...

to

...

operate,

...

easy

...

to

maintain,

...

and

...

that

...

already

...

performs

better

than

...

many

...

of

the

...

"high"

...

tech

...

plants

...

in

Honduras.

As Honduran communities learn of the AguaClara technology an ever increasing number are requesting that they be considered as potential sites for future water treatment plant projects. Site selection proved to be a challenge during the fall of 2007. The community of Moroceli was a top candidate because of its proximity to Tegucigalpa, size, and the recent construction of a new water storage tank at an ideal site overlooking the town. Unfortunately, poor engineering by the agency responsible for building the new tank left the tank high, dry, and unusable. Without water in the new storage tank Moroceli was no longer a viable candidate and APP helped identify additional communities that were close to Tegucigalpa in the Amarateca valley. A series of community meetings and engineering studies ensued and before long Tamara was identified as an ideal community. Tamara has a population of 3500, a well organized water board, and a single water supply serving the community. APP was already working with Tamara to extend their distribution system and so the addition of a water treatment plant was a logical next step.

the

worked

with

the

3

plant

We

anticipate

that

the

training

period

will

be

shorter

in

but

a

significant

training

period

...

of

at

least

...

several

months

...

will

always

be

necessary

to

ensure

that

have

the

experience

and

confidence

to

continue

...

operating

...

the

plant.

...

It

...

is

essential

that

the

become

completely

familiar

with

all

of

to

make

changes

and

...

repairs

...

to

the

as

needed.

...

One

...

of

...

the

...

reasons

...

that

...

the

high

tech

fail

is

...

because

the

It

is

our

a

that

the

construction.

...

We

...

are

...

currently

...

building

...

water

...

treatment

...

plants

...

with

...

a

...

capital

...

cost

...

of

...

$20

...

per

...

person

...

served.

...

We

...

anticipate

...

that

...

we

...

will

...

be

...

able

...

to

...

lower

...

that

...

cost

...

as

...

we

...

move

...

from

...

the

...

prototyping

...

phase

...

to

...

steady

...

construction.

...

Assessing

...

and

...

developing

...

appropriate

...

funding

...

sources

...

for

...

the

...

capital

...

costs

...

became

...

a

...

priority

...

during

...

the

...

latter

...

half

...

of

...

2007.

...

Our

...

circle

...

of

...

partners

...

has

...

continued

...

to

...

grow

...

with

...

the

...

addition

...

of

...

the

...

First

...

Congregational

...

Church

...

of

...

Ithaca

...

and

...

Somers

...

Rotary

...

Club.

...

The

...

Somers

...

Rotary

...

club

...

is

...

taking

...

the

...

lead

...

in

...

funding

...

the

...

Tamara

...

project.

...

We

...

hope

...

to

...

build

...

5

...

water

...

treatment

...

plants

...

in

...

2008

...

and

...

thus

...

we

...

will

...

continue

...

to

...

explore

...

additional

...

funding

...

sources.
