The Service Provider shall assist the County with site selection for flow monitor and rain
gauge equipment relocations, installation, diagnostic, maintenance, repair, field
confirmation, data analysis and reporting services for the County's network of permanent
monitors and rain gauges at various locations throughout New Castle County. The Service

hydraulics. The Service Provider shall be provided with as-built drawings where available,
but shall not rely upon as-built drawings to confirm site suitability.
NOTE: Service Provider shall provide all wireless communication, including any necessary
cellular upgrades (e.g. SIM Card), for the flow monitors and rain gauges as part of this

for a minimum of two (2) rainfall events, each event with a minimum rainfall amount of
0.25". The Service Provider shall provide the County with a written summary of the data
review and recommendation regarding the monitor/rain gauge site suitability. If the site
is found to be unsuitable, an alternate location shall be selected, and the monitor/rain
gauge installed at no additional expense to the County. The site selection and installation
requirements are also applicable to the monitors rotated across the various County sewer
basins.

monitors. Confirmations shall also be performed after any repair/maintenance at a
specific monitor location.
3. Records of the confirmation, including monitor site, date and results shall be
included as part of the web-based reporting system. Field confirmation data shall
also be displayed on the monitor site's hydrograph and scattergraph.
