Notes :
Analysis based upon drawings and data provided.Station recommendations are preliminary.
GPD values impact retention times only, not line sizing or hydraulics. GP laterals to be
1.25".
Analysis valid only with pipe type listed .
General recommendations for valve placement are: clean out valves at intervals of
approximately 1,000 ft and at branch ends and junctions; isolation valves at branch junctions;
and air release valves at changes in grade of 20 to 25 ft or more and/or at intervals of 2,000
to 2,500 ft. Lateral kits comprised of a ball and check valve are required to be installed
between the pump discharge and street main on all installations. Laterals should be located
as close to the public right of way as possible.
Quantities of grinder pumps, pipe, and valves are indicated on the cost page. The model of
grinder pump(s) indicated is based upon the initial information provided to us but may not be
the most appropriate for the specific location or requirements of the project. Costs of these
items and their installation are best obtained from sources in your region. We recommend
you contact your local distributor of Environment One products for additional
recommendations.
