| Swanland’s village pond greatly enhances the centre
of the village. However the water quality is often very poor in hot
weather and especially so after the borehole in the old pump house
was capped off, thus cutting off the pond’s only supply of clean
make up water. The only replenishment water the pond gets now is from
rainfall into the pond and some run off from the road drains to the
west of the pond. The road drain is polluted both from traffic oil
and grease and also from nutrients running off adjacent agricultural
land. |
| A comprehensive report by Hugh Roberts of Pond
Conservation has recently been submitted to the Parish council
to attempt to remedy this and other causes of the problem.
The black square raft that is floating at the west end of the pond
is an ultra sonic device that (hopefully) will eliminate, or at least
reduce algae in the water - this picture shows it being installed. |

Beneath the floating raft is an electrical powered ultra sonic transmitter
beams ultra sound waves across most of the pond. These are not harmful
to fish or plants but it is claimed they will destroy the algae.The
unit is being loaned free for a trial period and we have yet to see
how effective it will prove. However it is only tackling one symptom
of poor water quality and not its true cause. |
