There are installed wet wells for the direct withdrawal of mobile technics near to
industrial-fire-prevention tanks.
Sewerage. Industrial flows from equipment washing (1-2 times a year) by gravity
flow are going into treatment facilities of industrial sewage waters and after corresponding
clearing in tank of industrial-rainfall run-offs. (ЕP 12.5-200-1-1 with pump HB 50/50) and
then are pumped over on ponds-evaporators.
There are provided wells with hydraulic lock in a view of fire safety on outlets from
technological areas.
The industrial-rain sewerage is made from steel electrical-welded pipes in accordance
with GOST 10704-91 by diameter 219х4.5mm with the reinforced anticorrosive isolation.
Discharge of household flows is carried out in cesspool with the subsequent
transportation in places coordinated with SES. Network of the household sewerage is
designed from ceramic sewer pipes by diameter of 150mm in accordance with GOST 286-
82.
In camp the water is supplied for household and fire-prevention needs.
For household needs the water is supplied through pipeline by diameter of
57x3.5mm, L=500m, from water treatment installation of CGTU area.
Intra-areas networks of household water-supply line are designed from steel
electrical-welded pipes GOST 10704-91 D57х3.5; D25mm with the reinforced anticorrosive
isolation.
For fire-prevention needs the water is supplied through pipeline D108х4mm, L =
500m (two lines), from fire-control system of CGTU area.
Firefighting is carried out from fire hydrants installed on the loop network of
fireproof water-supply line.
Intra-areas networks of fireproof water-supply line are designed from steel electricalwelded
pipes GOST 10704-91 D108х4mm with the reinforced anticorrosive isolation.
Household flows are going into sewage pump station through gravity sewerage and
then into treatment facilities of household flows. Treated household flows are pumped over
by pump station on ponds-evaporators of CGTU area through pipeline D89х4.5 GOST-91
L=700m with the reinforced anticorrosive isolation.
Gravity network is designed from ceramic pipes D150 in accordance with GOST
286-82.
Internal networks of household water-supply line are designed from steel galvanized
water-gas pipes D15-32mm GOST 3262-75 with painting by oil paint for 2 times in
accordance with GOST 8292-85.
There are provided electrical water heaters for hot water preparation.
