The Project Includes Reconstruction Through A Complete Replacement Of The Pipes Of The External Supply Water Supply From The Water Points To The Pressure Tanks Of The Villages Of Filaretovo, Malko Selo, Sokolartsi And Topuzevo, Following The Existing Route. Through The Reconstruction, A Problem-Free And Permanent Supply Of Drinking Water, With The Necessary Qualities, Pressure And Quantities, Will Be Ensured For The Population Of These Villages. The Total Length Of The Water Pipe, Distributed By Sections With Diameters, Is As Follows: Route 01 - Gravity Pressure Water Pipe From Catchment Area 1 To Catchment Area 2 With A Length Of 410.96 M, Is Replaced With Pe100rc ∅90, Pn10; Route 02 - Gravity Pressure Water Pipeline From Collection Shaft 2 (After Catchment Areas) To Hp 300 M3 With A Length Of 5759.52 M Is Replaced With Pe100rc ∅110 Mm, For Different Pressures, According To The Graphic Part; Route 03 - Gravity Pressure Water Pipeline From Hp 300 M3 To Hp Sokolartsi With A Length Of 4648.16 M Is Replaced With Pe100rc ∅110 Mm From Hp 300 M3 To Shsk To Hp Topuzevo (3621.16 M) And With Pe100rc ∅90 Mm From Shsk To Hp Topuzevo To Hp Sokolartsi (1027 M); Route 04 - Gravity Pressure Water Pipeline From Shsk To Nr Topuzevo To Nr Topuzevo With A Length Of 72 M Is Replaced With Pe100rc ∅90 Mm, Pn16. Rehabilitation And Replacement Of Fittings In Existing Facilities - Reservoirs, Shafts And Others Is Planned, Namely: Replacement Of Fittings In A Dry Chamber Of An Existing 300 M3 Nr And The Reservoir Adjacent To It, In The Same Property Supplying Water To The Village Of Filaretovo And The Village Of Malko Selo; Replacement Of Fittings In The Dry Chamber Of The Existing Nr Sokolartsi; Replacement Of Fittings In The Dry Chamber Of The Existing Nr Topuzevo; Existing Relief Shafts Are Shut Down As Part Of The System; New Manholes Air Bag With Triple Action For The Prevention Of Airbags, Negative Pressure Or Hydraulic Shock, In The Necessary Places Indicated In The Graphic Part Of The Project; New Drain Shafts (High And Low), In The Necessary Places Indicated In The Graphic Part Of The Project; New Shafts With Pressure Reduction, In The Necessary Places Indicated In The Graphic Part Of The Project; New Shaft Shut-Off Valves At The Diversion To Nr Topuzevo. To Regulate The Pressure In The External Water Pipes, It Is Necessary To Install Pressure Regulators In The System. For Emptying The Water Pipes In Case Of Accidents And / Or Repairs, Manholes (Outlet) Are Provided. Automatic Air Vents Are Provided For Venting The Network During Filling And/Or For Releasing Air When Emptying A Given Section Of The Network. A Separate Shaft With Shut-Off Valves Is Provided At The Branch From The Water Pipeline From Nr300 M3 To Nr Sokolartsi To Nr Topuzevo. Stopcocks Are Manually Operated. Route 2 Of The Pressure Water Pipeline From Nr 300 M3 To Nr Sokolartsi From Km +1 100 To Km +1 510 Passes Through The Regulation Of The Village Of Filaretovo. A Part Of It, With A Length Of Almost 20 M Falls Within The Scope Of The Iii-706 Republican Road. The Existing Crossing Will Be Used For The Passage Of The New Water Pipeline Under The Golyama Kamchia River. Support Blocks Are Provided For The Horizontal Breaks Of The
