Cistern Specifications & Operational Standards – Updated Jan. 1, 2015
Guidelines for hook-up of curb-stop to cistern and emitter assembly
1. To standardize all member hook-ups the LNCPWC requires that members use 3/4 inch diameter, Series 200 municipal pipe (Rated to 200 PSI) from the curb-stop to the cistern. (Regular black water pipe will no longer be accepted, and if used, our operator will not install your water service).
Extra ¾ pipe must be coiled in the cistern to allow for installation and removal of the flow emitter assembly. Measure this by pulling 5 ft. extra out of the cistern neck. As an option the LNCPWC recommends using Blue Aqua G1331 flexible water pipe available at companies like Southern Drip. A 15 foot prepared pipe with ¾ inch NPT adapter fittings should cost approximate $75.00.
A minimum operating pressure of 20 PSI has been designed for at all curb stops. Remember there will be some pressure losses in your system but these are minor when compared to raises in elevation.
The math is simple – for every 2.31 feet in the raise of a pipe the pressure drops 1 PSI.
It is very important to consider this fact when determining where you are planning to install your cistern.
2. The Co-op will provide all members with the vertical mounting brackets and anchors, and will install the float & flow emitter once the landowner has properly installed the vertical mounting bracket. Please call ahead so the bracket can be dropped off ahead of time. After our operator has flushed your line and determined correct chlorine levels he will install the flow emitter assembly. This equipment will restrict flow to the number of units purchased and stop the flow to the cistern once the cistern is full.

The cost of the flow emitter is included in the final unit cost, so there is no charge at time of pickup.
(One flow emitter assembly per cistern).
3. The cistern must be “frost free” to prevent damage to the flow control assembly. The member is responsible for repairs required to the line from the cistern to the curb-stop and should frost
damage occur to any part of the flow control assembly in the cistern, a minimum $75 service
call charge and an invoice for replacement parts will result. Do Not Try to Repair Yourself, only
LNCPWC approved parts installed by our operator will be acceptable.
(Please insulate the top of your cisterns)
4. The Alberta Health Services guidelines do not allow Co-op members to connect to the curb stop until the Co-op’s lines have been flushed and chlorinated. Only the Co-op operator is authorized to do flushing and chlorine testing, and when done will he complete the water connection.
5. The Co-op will not allow water to be taken between the curb-stop and the emitter (for example
via: a cattle waterer, a hydrant, etc.). Any remedial work to correct wrong hook ups will be done at the member’s expense. The installation of any control device, or tee between the LNCPWC curb stop and the control assembly is considered as tapering and must be removed at the expense of the landowner.
6. As part of the arrangement between the Co-op and its members it must be understood that the LNCPWC operator must be allowed to inspect the emitter assembly in any member’s cistern. His job is to maintain a safe source of drinking water for you and your family. Part of his job is to rotate the curb stop valves, do end of line chlorine testing, complete locates and many other tasks. So, if you see our operator say “hello”.
