Tenders Are Invited For Preparation Of Design Documentation For The Construction Of A Sanitary Sewage Networ ... in Poland

Work Detail

1. The Subject Of The Order Is The Preparation Of Design Documentation For The Construction Of A Sanitary Sewage System In The Towns Of Radkowice, Radkowice Kolonia And Part Of The Town Of Bronkowice In The Pawłów Commune. For The Purposes Of Building A Sanitary Sewage Network In The Commune, The Concept Of The Sanitary Sewage System In The Towns Of Nieczulice, Wieloborowice, Trzeszków, Pokrzywnica And Radkowice Kolonia, Pawłów Commune Was Developed, Which Is An Integral Part Of This Swz (The Concept Is The First Stage Of Preparing The Construction And Executive Design Documentation, Therefore It Is Illustrative And May Change During The Implementation Of The Project). The Sanitary Sewage System Was Designed Along The Existing Buildings. Variant I (Adopted By The Ordering Party As Binding) Assumes The Construction Of A Sewage System As A Gravity-Pressure System Using Network Sewage Pumping Stations. In Places With A Significant Decline In The Terrain And In Remote Areas, It Is Planned To Use A Pressure Sewage System With Home Sewage Pumping Stations. Pressure Channels From Individual Pumping Stations Were Run Parallel To The Gravity Channels. The Gravity Sewage System Is Designed From Pvc Pipes Sn8-12 Kn/M2, In Accordance With The Pn-En 1401:1999 Standard, With Diameters Dn160-200Mm. The Designed System Of Gravity Channels Will Ensure The Minimum Flow Speed In The Channel, Ensuring Its Self-Cleaning, But Without Exceeding The Maximum Speed. The Designed Sanitary Channels Will Be Equipped With Through-Connection, Break, Cascade, Expansion And Cut-Off Wells In Front Of The Network Pumping Stations. Plastic Wells And Concrete Wells Are Expected To Be Used. The Use Of Plastic Manholes Will Enable Their Inspection And Thus Facilitate The Operation Of The Sewage Network. The Use Of Non-Accessible Plastic Wells Will Facilitate Installation And Increase The Tightness Of The Sewage Network, And Thus Reduce The Operating Costs Of The Sewage Treatment Plant Due To The Reduction Of Groundwater Infiltration. Wells Are Designed In The Network Approximately Every 60 M, And At Every Change In Slope And Bend In The Canal. The Route Of The Designed Sewage Networks Has Been Adapted To: The Existing Buildings; Area Infrastructure: Underground And Above Ground; Elevation System Of The Terrain; Grade Of Existing Roads. The Area Covered By The Above-Mentioned Concept Has An Existing Single-Family Residential Development, Which Has Not Yet Been Connected To The Sanitary Sewage System. As A Result Of The Implementation Of The Planned Investment, Sewage Management In These Towns Of The Pawłów Commune Will Be Organized Through The Construction Of A Sanitary Sewage System. Collecting Municipal Sewage In Tight Sewage Systems And Transporting It To The Sewage Treatment Plant Will Significantly Improve The Condition Of The Natural Environment Directly In The Investment Area And Will Contribute To The Protection Of Surface And Underground Waters. The Result Of The Implementatio
