About this file

This document contains a request for proposal for utility modernization services at Chievres Air Base in Belgium. The U.S. Army Corps of Engineers is soliciting proposals for upgrades to water, wastewater, and electrical utilities at the base. Interested offerors must register to attend an in-person site visit by June 18, 2021 to receive details. The solicitation seeks design and construction services for modernizing pumping stations, water mains, sewer lines, and related infrastructure to improve base operations. Proposals are due at a later date yet to be determined. The selected contractor will be responsible for replacing aging assets to meet current standards and capacity needs at the installation in support of the Department of the Army's European Command.

Data coming from Utility Master Plan and Planning Charrette Report

Description Value Unit

2018 water consumption 47,000.00 m³

2018 Base Population 833.00 capita

2018 water demand / capita 151.00 L/cap

2018 water demand / day 128.704,00 L/D

Future on post population 1,869.00 cap

Future off post population 678.00 cap

Future total population 2,547.00 cap

On post personel flow 50.00 gal/cap/D

Off post personnel flow 30.00 gal/cap/D

On post personel flow m³ 2.19*E-06 m³/cap/s

Off post personnel flow m³ 1.31*E-06 m³/cap/s

Peak rate factor 4.00 /

Hypothesis

1) All new construction and facilities discharge their wastewater to the

Community support district.

2) The pumping system must be able of emptying the volume of the wet well in

1h30. Release can only be done during certain period of the day.

3) The system for measuring the water level in the wet well is triggered when the water level reaches 155 m³.

4) The volume of wastewater discharged between 10.00 and 12.00 am corresponds to one hour of peak flow and 5 hours of average flow.

5) The volume of wastewater discharged between 14.00 and 16.00 pm corresponds to half an hour of peak flow and 3.5 hours of average flow.

6) The volume of wastewater discharged between 22.00 pm and 06.00 am corresponds to one hour of peak flow and 9 hours of average flow. It was decided that the wastewater discharge between midnight and 06.00 am could be corrected by a factor of 3.

Flow definition total on post personnel flow (1) 93,450.00 gal/D total off post personnel flow (2) 20,340.00 gal/D

Total flow (1+2) 113,790.00 gal/D

Peak flow 455,160.00 gal/D

Average daily flow per capita 44.676 gal/D total on post personnel flow (3) 0.004094291 m³/s total off post personnel flow (4) 0.000891149 m³/s

Total flow (3+4) 0.00498544 m³/s

Peak flow 0.01994176 m³/s

Average daily flow per capita 1.96*E-06 m³/s

Wet well volume definition

Peak flow / Hour 18,965.00 gal/h

Wet well volume = 1h of peak flow + 5h of mean flow (longest waiting period : 4 pm to 10 pm) 42,671.25 gal

Wet well volume = 1h of peak flow + 5h of mean flow (longest waiting period : 4 pm to 10 pm) 161.53 m³

Wet well storage volume 162.00 m³ detection level 155.00 m³

Total Dynamic Head (TDH)

Based on the Utility Map of CAB and on the results of the topographic survey, it is possible to compute the total dynamic head (TDH).

To do this, the Colebrook-White model was used with the following parameters :

- Flow : 115 m³/h

- Viscosity: 1.569 mm²/s

- Number of pumps: 2

- Type of installation: parallel pumps

- Geometrical height: 8 m the individual discharge piping inside the wet well will be made of metal / stainless steel and will have a diameter of 100 mm (DN 100) to ensure maximum longevity.

- Pipe length: 8 m

- Roughness: 0.25 mm

- Elbows 90°, non-return valve, T-connections, … : 1.9 m

- Speed : 1.681 m/s

This shows that the pressure losses inside the wet well created by the installations are equivalent to 0.5412 m

As far as the common discharge pipe is concerned, it will be made of HDPE with a diameter of 200 mm (DN 200).

- Pipe length: 450 m

- Roughness: 0.25 mm

- Elbows 90° : 10.8 m

- Exit : 1 m

The pressure drop obtained on the force main is 5.357 m

By adding the two pressure losses obtained above, as well as the static discharge pressure.

This gives a total head of 13.9 m.

Pumps definition

The flow rate and the total dynamic head made it possible to find the most suitable pump operating point for this project as shown in the diagram below.
