Annual Maintenance Agreement between Biotank Ltd. and the Householder
for 5 PE system.
This annual maintenance agreement for the BioKube wastewater treatment system is
priced at an annual subscription price of £110. The amount includes VAT, but
excludes consumables and spare parts. The amount is index-linked.
The maintenance agreement comprises an annual inspection as well as service visits in

system. If
a specific alarm is not caused by a treatment system malfunction, the visit
in question will be invoiced at standard service rates. (Available at
