Mahaweli
could solve sand crisis if properly managed
By Quintus Perera
Welikanda -- Passing Polonnaruwa, the Manampitiya Bridge that accommodates
the railway track and the road on the same passage alternately could
be one of the longest bridges in Sri Lanka.
Beneath
it flows the great Mahaweli river, which could be a great source
of sand for construction if properly used. Two weeks ago when The
Sunday Times FT team visited the area, the entire stretch of the
river across measuring about 160 metres could be seen as a huge
sand mass and within this sand mass there were small patches of
water holes.
Manampitiya bridge is the gateway to the East from Polonnaruwa and
due to security risks, it is heavily fortified with troops on other
side. Little beyond Manampitiya is Welikanda. Mahaweli means great
sand and Welikanda means mountain of sand.
True to this connection to sand in the river plus the area a little
beyond the bridge towards Welikanda, there is hectic activity: Mountains
of sand piled up, rows of tractors unloading sand and a large number
of huge trucks being loaded with sand to be transported to areas
where sand is scarce, but at a great price. Most of these trucks
travel to Colombo.
There
is a scarcity of sand for construction purposes in most parts of
the country especially in the Western Province. Manampitiya sand
dealers said the sand here is classified as the best and a cube
of this sand in Colombo would cost Rs 6,000 to 6,500 per cube. Normally
sand costs around Rs 4,500.
We wondered whether miners had got permits to remove this large
resource or sand or whether it was an illegal operation that was
going on. An army officer nearby said sand mining is on permits
and mostly upstream.
When we walked upstream around four kilometres through scrub jungle
on a tractor track there were a large number of people dipping in
some of the water holes in the vast sand mass and bringing up basket
loads of sand to the shore which are then briskly loaded to tractors.
Sand
mining at Manampitiya is legal and 80 people around the area have
formed the Mahaweli Sand Mining Co-operative Society Ltd for this
purpose. Each member employs four sand miners and each miner brings
in one cube of sand per day. The daily average is around 400 cubes
per day.
K
Bandara, President, Co-operative Society said, “Manampitiya
sand is the best. There are no stones and a cube of it in Colombo
fetches around Rs 6,000 to 6,500 but we are selling at Rs 900 to
Rs 1,000 maximum”. He said that most of the sand is taken
to Colombo and the day’s collection is cleared the same day.
Usually miners dip in the water and bring up the basket of sand
and fill the barges. But in Manampitiya it is quite different and
difficult because after mining it has to be carried across sand
dunes of about 50 feet with each load weighing around 200 ilos.
When asked whether the Co-operative Society itself could transport
the sand to Colombo so that they could have a better margin of profit,
Bandara said that they are very poor and cannot afford such heavy
investment. He said that a truck normally holds about four cubes
and to transport that load to Colombo the transporter charges Rs
16,000 to 20,000.
In
addition to the 320-odd miners, there are also the tractor drivers,
loaders and truck drivers and cleaners and altogether there are
about 750 workers on site. In this sand project there are also several
thousands employed indirectly.
An experienced transporter in Colombo said that the cost of transport
per cube to Colombo could be Rs 2,000 maximum. Considering the selling
price of sand per cube at Rs 1000 at mining site and the actual
transport cost of Rs 2,000, the price of a cube of Manampitiya sand
would be Rs 3,000. As in many other cases, the middleman’s
exploitation appears to be criminal as he would get up to Rs 3,000
to 3,500 as his profit.
Bandara
said that a large number of poor people who live around the area
are entirely dependant on sand mining here. But the sand mining
operations is seasonal and lasts only for six months per year. During
the dry season the entire river resembles a huge patch of sand,
but with the coming of the wet season the entire sand mass would
be covered with a huge sheet of water impacting on the miners and
their jobs and with them several thousands in-between.
Considering
all the data available on sand mining and availability, it is reasonable
to assume that there is sufficient sand available in the country.
The biggest problem is transport. There also appears to a failure
of forecasting the quantum of sand that is available for mining
by official agencies.
According to a high official of the Geological Survey and Mining
Bureau (GSMB) , prospects of an impending sand shortage were known
more than three years ago.
However no mechanism was created to get sand from any other source
with sand mining being prohibited in various places. The sea sand
available at Muthurajawela is not mined for the use of construction
work, but because the authorities failed to find any alternative
way for the last three to four years, the sand that was mined for
the use of the Katunayake Colombo Expressway is now allowed to be
used for construction purposes.
The
GSMB was unable to indicate the quantity of sand available for mining,
the demand and supply positions. It was also unable to say in the
prohibited areas, how much of sand has been mined in the past.
Though GSMB accepted treated sea sand as an alternative to river
sand, for the last three years the authorities have failed to commence
any tangible work on off-shore sand mining. On the other hand private
sector entrepreneurs are forging ahead in finding out new processes
to obtain large quantities of sand inland.
At
a recent seminar conducted to educate contractors the suitability
of sea sand for construction work it was revealed that large quantities
of sand is available in the North and East, especially in areas
such as Jaffna, Mannar and Kilinochchi. It appears that even the
Mahaweli, if systematically operated, has a large resource of sand
that could be extracted.
