Work Detail

1. The Subject Of The Order Is The Service Called Preparation Of 2 Complete Design And Cost Estimates For The Construction Of A Sanitary Sewage Network In Zagrody And Przybysławice For Stage 1 And Stage 2. 2. Estimated Lengths Of The Designed Networks: 2.1. Stage 1 - 4328.5 M - Main Gravity Network - 1778.5 M - Side Gravity Network - 1176 M - Pressure Network - 1374 M2.2. Stage 2 - 2853.5 M - Main Gravity Network - 1771 M - Side Gravity Network - 838.5 M - Pressure Network - 244 M3. Description Of The Stages Of The Designed Sanitary Sewage Network: 3.1. Stage 1 - Gravity Sanitary Sewage Network Along The Municipal Road Ul. Nadstawna In The Towns Of Zagrody And Przybysławice. Due To The Terrain Of The Road With A Slope Towards The West, Two Gravity Collectors Were Planned Running Along The Road. One From The Side Of The Provincial Road Will End With The P1 Pumping Station And A Discharge Pipe Leading Sewage Towards The Swł1 Connection Point In The Vicinity Of The Newly Designed Sewage Treatment Plant. Due To The Presence Of Shallow Groundwater Near The Ponds, It May Be Necessary To Use An Additional Sewage Pumping Station To Cover The Sewage System In The Area Of ​​The Intersection Of Ul. Nadstawna With A Provincial Road. In Agreement With The Investor, The Garbów Commune Recommends Running The Sewerage Network Along Roads On Private Plots Or In A Way That Does Not Interfere With The Road Infrastructure. In Stage 1, The Area Intended For An Investment With Dense Buildings Close To A Municipal Road Often Does Not Allow Running The Network On Private Plots Due To The Lack Of Sufficient Space. At The Design Stage, Appropriate Arrangements Should Be Made With Land Managers To Determine Optimal Network Routes. With The Investors Consent, It Is Permissible To Use Tees Instead Of The Shown Inspection And Connection Chambers In Cases Where There Are A Significant Number Of Them On Straight Sections. Branch Sections Of The Network And Changes In The Direction Of The Network Route Must Be Carried Out Using Inspection Wells. 3.2. Stage 2 - Gravity Sanitary Sewage Network Along The District Road Ul. Lubelska And On The Section Connecting Ul. Lubelska And Ul. Nadstawna And The Streets In The Area Of ​​The Old Sugar Factory, Ul. Cicha, Cukrowa, Jana Pawła Ii, Zielona In Zagrody. The Stage Reaches The Primary School, Galeria Cukrowa, And A Housing Estate. Due To The Terrain And The Need To Add Further Stages, It Is Necessary To Use A P7 Pumping Station. At This Stage, Two Main Collectors Collect Sewage From The Catchments Preceding Them, From The Towns Of Zagrody And Wola Przybysławska. The Sewage Is Discharged Towards The Connection Point Near The Newly Designed Sewage Treatment Plant. Taking Into Account The Area Of ​​The Center Of Zagrody, Which Partially Has A Sewage System, It Is Necessary To Check Its Condition And Patency Before Implementing The Project Or At The Design Stage. It Is Recommended To Renovate Or Replace The Existing Sections Of The Sewage Sy
