Tissa
Wewa
is
an
ancient
irrigation
tank
was
built
by
King
Devanampiya
Tissa
(250-210
BC).
Only
Panda
Wewa
and
Abhaya
Wewa
are
considered
to
be
older
than
Tissa
Wewa.
The
embankment
of
Tissa
Wewa
is
11,000
feet
long
(Two
miles)
and
25
feet
high.
The
width
of
the
top
of
the
reservoir
was
found
to
be
12
feet
to
18
feet.
Base
of
the
embankment
is
160
feet.
Tissa
Wewa
has
an
area
of
approximately
550
acres.
Mahawansa
reports
that
King
Bhatikabaya
(20
BC-9
AC)
pumped
water
using
a
machine
up
to
Ruwanweli
Seya
and
sprayed
water
to
flowers
which
covered
the
full
stupa.
Further,
water
from
this
reservoir
was
also
used
to
fill
the
tanks
of
Ranmasu
Uyana,
the
Royal
water
garden
next
to
the
Isurumuniya
Viharaya.
Tissa
Wewa
receives
water
through
the
ancient
canal
of
Jaya
Ganga,
an
ancient
canal
originating
at
Kala
Wewa.
The
excess
water
is
released
to
the
Malwathu
Oya
river.
The
embankment
of
the
Tissa
Wewa
tank
is
approximately
3
km
long.
Parker
in
1909
reports
that
the
embankment
appears
to
be
in
original
state
(
that
of
1100
years
ago)
and
its
so
solidly
built,
with
little
maintenance
this
bund
will
last
forever.
Just
as
he
commented,
the
Tissa
Tank
continues
feed
water
to
the
Anuradhapura
even
today.
