bimr,
Thanks for your response. I might have not given enough information in my initial post so let me clarify further.

The waste water is not recycled into potable water. It is treated to a level where it could be used for toilet flushing ONLY.
The purpose of the "untreated water tank" is...
Hi
I am looking for any references on how to size a small wastewater facility for a 10 storey hotel. The system description is as follows:
Wastewater from showers and wash basins is collected in a tank in the basement. (Untreated water tank)
A treatment plant (Pumps, filters...etc) draws the...
Thank you for your responses and suggestions.
As for offsetting the pipes there shouldn't be any problem as it is architect's suggestion to combine the drainage stacks since he wants to reduce the number of shafts on the floor.
The building is actually a hotel and there are a total of 14...
Hi
I was wondering why I never see anyone combining drainage stacks. What is the logic behind it?
What I mean is:
DWV System
10 storey building and I have fixtures on both sides of the building
One 4" waste stack on each side for the sake of explanation. Both with an attendant vent stack...
Hi,
Can anyone point me to a method that can be used to estimate the water demand of a hotel? To be more specific I want to be able to estimate the daily water need of the hotel in order to size the water tanks. Is it based on the number of rooms? ..etc. Any references on the topic would be...
Hi,
I have a building of 4 stories that has a DWV drainage system.
Every waste and soil stack is accompanied by a vent stack.
Waste and waste and soil stacks are connected to inspection chambers on the ground floor level. The inspection chambers are position away from the building by a...
willard3,
There is nobody else in my office. But anyways, I suggest I will have to look harder till I find them. Thank you for taking the time to reply.

Hi,
Can someone point me to a manufacturer that makes Linear Slot Diffusers the connection spigot on the top of the plenum box. Are there any that makes those as standard? Or do they have to be custom made?
All the catalogs I have come across so far have side connections only. Thank you.
Best...
Hi,
I've been looking for some electronic product catalogs for AHUs for Cooling (Chilled water) & Heating (Electric). The exact reason is that I want the electricity load for that kind of equipment. I've went through Greenheck's CAPS Engineer but I can't seem to change the power supply taken...
Artisi,
Thank you for your response. I had already looked at it before I posted this, but what came to my mind was that power plants have different requirements from residences. I also wanted to get an idea what the standard practice was, away from all of the technical jargon and numbers. And I...
Hi,
I was wondering what is the most recommended pump combination in the following situations.
1- Underground pump room for a residential swimming pool.
A submersible pump is required for filter backwash, draining the pool...etc.
My current thinking is (duty + 100% standby)
2- Submersible...
PEDARRIN2,
Thank very much for all the help you have been offering.
-What I can conclude is that the water reaches those temperatures from direct sun radiation and not from heat transfer from ambient air. Water storage tanks over here are usually placed on buildings' roofs and are not shaded...
Hi,
Where I live temperatures get really hot in the summer, around 110°F, and during summer if a cold water supply is opened the water that comes out is too hot to touch. This lasts for around 3 months out of the year. Does this mean that the "cold" water supply network inside the house should...
PEDARRIN2,
Thank you for your response.
I am familiar with what you are talking. I've went through the ASPE Vol 2 before and took a look at the curves and tables there. But I think you are using updated versions of those since I think they are quite old (~1920s).
From the data in ASPE:

Hi,
I have a question regarding using BS 6700:1997 to size water pipes. My issue is as follows:
on page 30, under (2.5-Pipe sizing) it states
The system shall be designed and installed so that the design flow rates given in table 3 shall be available at each outlet and any group of outlets...
