In 1974 the site
Siriu storage lake is founded for
the complex development works of
river Buzau.
This site has known a constant
development and therefore in 1984
it was turned into the Siriu –
Surduc subsidiary and later on the
Siriu – Buzau subsidiary.
The works for the Siriu storage
lake include: the dam made of local
materials with a clay concrete core,
the storage lake, the water catchment,
the irrigation galleries, the bottom
discharge gallery, the high water
outlet, the power dissipater which
were financed by MAPPM.
In 1979 the Surduc Siriu development
was promoted financed by the Ministry
of Electricity and then by RENEL:
the HPP Nehoiasu – water head
Siriu Pi=42 MW, rockfill dam h –
65 m, V = 1600 thousand cu.m. fillings,
lake V = 175 million cu.m., water
storage, HPP Surduc, Pi=166 MW,
HPP Surduc – water head Ciresu,
Pi=20MW.
Along the time, besides the hydropower
and hydrotechnic works, the subsidiary
also performed other works like:
edilitary ones, hydro upgrading,
road and bridge constructions, railways,
industrial platforms, civil construction,
administrative and social –
cultural buildings, industrial,
farming constructions, land upgrading
works, slope consolidation by means
of long anchors, rock consolidation
by means of high pressure groutings,
in-depth tightening, etc.
The drop in investments starting
with 1990, had an impact on the
“Hydropower Siriu –
Surduc Development”.
Therefore the Subsidiary Siriu
had to cover its working capacity
by performing a number of works
like for instance: water supply
of villages Minzalesti – Vintila
Voda, head office of CEC Patirlagele,
of CEC Siriu, of CEC Gura Teghii,
water supply of Gura Teghii, frame
saw hall and technologic platform
for wood processing Patirlagele,
market Patirlagele, the bridge over
motorway Viperesti – Tronari,
assembly center Movilita within
the Wholesale Market Bucharest,
Water Supply Brasov, regulation
river Sarata at Telejen financed
PHARE, water supply Ion Roata.
