Tenders Are Invited For Construction Of A Water Main, Pressure Tank And Internal Water Network In The Village Of Zlatolist, Municipality Of Sandanski

The Investment Project Includes The Construction Of A Water Supply Pipeline, Pressure Tank And Internal Water Supply Network In The Village Of Zlatolist, Municipality Of Sandanski. The Pressure Tank (Reservoir) Has A Volume Of 100 M3. The Reservoir Will Be Made Of Reinforced Concrete And Will Consist Of Two Water Chambers And One Dry Chamber. The Pipe Systems Will Be Located In The Dry Chamber - Inflow System, Overflow - Discharge System And Feeding System. The Water Chambers Have One Circulation Wall Each. A Cement Screed Will Be Filled Along The Bottom Of The Tank With A Slope. Waterproofing Will Be Done On The Outside Of The Enclosing Walls And On The Inside Of The Walls, Floor And Cover Plate Of The Tank. The Newly Built External Water Supply Will Connect With The Existing Eternite Water Supply Ф60, Passing North Of The Plot Of The Rozhensky Monastery And Will Reach The Pressure Tank Falling Under The Regulation Of The Village Of Zlatolist. The External Water Pipe Is 4,991.10 M Long And Will Be Made Of Pevp Pipes Ф75 Pn10. The Level Difference From The Water Intake Point To The Lowest Point Of The Village Of Zlatoist Is About 270 M. On The Steep Sections, It Is Planned To Strengthen The Embankment With A Geotextile System. Relief Shafts, Outflow Shafts And Av Shaft Will Be Built Along The Route Of The Water Pipeline. Before Crossing The Regulation Of The Village Of Zlatolist, The Water Pipeline Will Cross The River Zlatolishki Stream. After Crossing The River, The Aqueduct Enters The Regulation Of The Village And Reaches A Newly Built Road And A Drainage Channel. The Crossing Of The Road And The Drainage Canal Will Be Done Without A Trench Through A Horizontal Borehole. For The Internal Water Supply Of The Village With Water For Drinking And Domestic Needs, One Main Water Supply Branch Was Designed From The Water Meter Shaft To The Church St. George. The Water Meter Shaft Is Designed In Close Proximity To The Pressure Tank. Branches From The Main Water Supply Branch Were Designed For The Remaining Properties, The Routes Of Which Are Along The Existing Streets. The Internal Water Supply Network Is 1,659.10 M Long And Will Be Filled With Pe-Hd Pe100 Dn90 Pn10 Pipes. The Connection Between The Pipes And The Connecting Parts Will Be Butt-Welded. It Is Planned To Install 11 Fire Hydrants And Build 48 Fire Extinguishers. At 90° Elbows, Tees And Where The Water Pipe Is Plugged, Concrete Support Blocks Will Be Installed. The Design Depth Of Laying The Pipelines Is 1.50 M. Excavations Will Be Carried Out Unreinforced. The Pipes Are Laid On A Sand Bed And Filled With Sand 30 Cm Thick, After Which The Trenches Are Filled With The Excavated Soil. The Constructed Water Pipes Are Subjected To A Hydraulic Test And Disinfected.
