Biological and bathing pools (1.)
Biologically clear, chemical free water(Summary)
What could be a better way of getting
closer to nature than having a
dip in our own biological, environmental
friendly pool? These biological
pools – their pleasant, natural
appearance, practical filtering
systems and ornamental planting
material – make a relaxing environment
for this. The biological /
bathing pool gives interest in the
garden all year around, and as
an elementary part of the garden,
combines the advantages of the
ornamental lakes and commercial
pools. 
The biologically cleaned
water is chemical free, hence
non-allergen, does not need to be
drained for years, heats the water
up much faster; and with the endless
variations regarding pool size
and design its building and running
costs are reduced. The cost
of construction per square metre
is between 35-50 thousands forints
which includes the following:
design, geotextile and it installation,
pond liner and its installation,
water tightness test, filtering
system, its installation and accessories,
decoration, maintenance
and its tools and warranty regarding
the quality of water. |
