The first option may be suitable for systems optimized for exterior irrigation only. But regulatory authorities may not permit the use of such seasonal systems as part of a storm water control strategy. Year round systems can be protected from freezing by locating the pipes, pumps and cistern indoors and/or below the frost penetration depth[http://www.raqsb.mto.gov.on.ca/techpubs/ops.nsf/0/ee1f1756eacc00e18525808200628fbf/$FILE/OPSD3090.101%20Rev%231%20Nov2010.pdf].

The two primary operational concerns for RWH systems are:
The two primary operational concerns for RWH systems are:
*Will the cistern require entry for inspection in the future? How will this be accessed?

''RWH systems producing higher quality water will have additional maintenance requirements. These will depend on the the treatment technologies being used.''<br>
