Cistern Water Supply Inspections
In
many rural communities in Atlantic Canada, adequate groundwater or
treated piped-in supplies of potable water are not available. For
example, property around many coastal shoreline areas, such as Cow
Bay and Peggys Cove, have little surficial material to allow for dug
well construction or the drilled wells experience either iron and
manganese, arsenic, uranium and saltwater problems. So as an option
use of a cistern is a viable economic option. The collection of
rainwater from the roofs of buildings may be the only or best
alternative to supply household demands. This is especially true in
other areas of the province where dug wells have an insufficient
yield and drilled wells contain elevated levels of contaminants such
as hardness, sulfates, or chlorides. A residential cistern system is
approximately $10,000 to $15,000 if constructed at the time of
laying the building foundation, about the same price as a drilled
well with a treatment system or a large holding tank system,
however, it requires treatment, yearly cleaning, and space for a
storage compartment.
As each location and project differs in climate, water demands and
physical characteristics, past experience has shown that an on-site
evaluation of the property is a definite necessity. There are many
factors which have to be observed and information obtained by an
on-site visit identified by a detailed water supply survey.
In general, the amount of water that cistern systems can supply is
dependent on several factors:
- the amount of rainfall
- the area collection surface (ie. roof size)
- size of the storage tank
