Losses in supply infrastructure Refik Samet samet <a href="mailto:samet@eng.ankara.edu.tr">samet@eng.ankara.edu.tr</a>Dear friends,

I am interested in modeling the losses in supply infrastructure using WEAP. Does anybody have any experience to determine where the losses are greatest in supply infrastructure?

The greatest losses are usually in urban areas, particularly where the distribution infrastructure is ageing.

RE: Losses in supply infrastructure Jeff Rempel jeffreyrempel <a href="mailto:jeffrey.rempel@postgrad.plymouth.ac.uk">jeffrey.rempel@postgrad.plymouth.ac.uk</a>Dear Refik,

As part of a groundwater management strategy that I developed for the City
of Calgary in 2005 we estimated urban groundwater recharge from surface wat
er fed supply mains.

According to the folks i spoke to from city infrastructure - waterworks, th
ey lose approximately 12 % of water from the water main connections and L's
. I would suggest that connections would be responsible for the majority o
f losses but do not have a reference for you.

Supply Losses Mohammad Rayej rayej <a href="mailto:rayej@water.ca.gov">rayej@water.ca.gov</a>Generally, major losses in supply infrastructure (Storage and
Conveyance) are direct evaporation and seepage.
where both can be modeled by WEAP.

On Storage side, direct evaporation is a major loss which can be
explicitly specified in WEAP's Reservoir module.

On Conveyance side, "irrecoverable" seepage loss and evaporation can be
modeled as loss in Transmission Link
expressed a fraction of supply delivered at the upstream end of the
Link. The "recoverable" seepage losses, however,
can be captured and routed to a ground water element in WEAP.
