| (76) Sanitary survey--An onsite review of a public
water system's adequacy for producing and distributing safe drinking
water by evaluating the following elements: water source; treatment;
distribution system; finished water storage; pump, pump facilities,
and controls; monitoring, reporting, and data verification; system
management, operation and maintenance; and operator compliance.
(77) Sensitivity--The maximum log removal value (LRV)
that can be reliably verified by a direct integrity test in membranes
used to treat surface water or groundwater under the direct influence
of surface water; also applies to some continuous indirect integrity
monitoring methods.
(78) Service line--A pipe connecting the utility service
provider's main and the water meter, or for wastewater, connecting

generally at the customer's property line.
(79) Service pump--Any pump that takes treated water

operation, or maintenance of the source, treatment, storage, or distribution
systems.
(81) Stage--In reference to a reverse osmosis or nanofiltration
membrane system, a set of pressure vessels installed in parallel.
(82) System--Public water system as defined in this

(83) Transfer pump--Any pump which conveys water from
one point to another within the treatment process or which conveys
water to storage facilities prior to distribution.
(84) Transient, noncommunity water system--A public
water system that is not a community water system and serves at least
25 persons at least 60 days out of the year, yet by its characteristics,
does not meet the definition of a nontransient, noncommunity water
system.
(85) Vessel--In reference to a reverse osmosis or nanofiltration
membrane system, a cylindrical housing unit where membrane modules
are placed in a series to form one unit.
(86) Wastewater lateral--Any pipe or constructed conveyance
carrying wastewater, running laterally down a street, alley, or easement,
and receiving flow only from the abutting properties.
(87) Wastewater main--Any pipe or constructed conveyance
which receives flow from one or more wastewater laterals.
(88) Water system--Public water system as defined in
this section unless otherwise modified (i.e., distribution system).
