1663 Georgia View Road is a proposed affordable housing development on Galiano Island, BC by the Gulf Islands Galisle Affordable Rental Housing Society (GIGARHS). The preliminary concept for the development consists of 12 residential units ranging from 1 to 3 bedrooms. GIGARHS has retained MSR Solutions Inc. (MSR) to investigate water demand requirements as well as the feasibility of utilizing rainwater to supplement the water system. There is currently no plan to utilize graywater.

A well treatment system with filtration, UV disinfection, and residual chlorination will meet Island Health requirements and ensure well water is safe to consume.

Potable water storage is provided for the development. It will meet the maximum month condition for reasonably assumed flows and can be supported in an application for a construction permit to Island Health. 76 m3 of storage was required to meet fire demand, which can be sourced from rainwater collected from the roofs. Providing a connection from the fire storage to the potable system will add an additional temporary emergency source of water should the well not be able to provide enough for some reason. Proper valving should be in place to ensure usage in emergencies only.

A rainwater collection system will provide a means of additional water source to help assist in irrigation demands. Because there is no requirement to treat rainwater before irrigation it is a very cost-effective means for providing the water needed to irrigate.
