CITY of DENTON MUNICIPAL UTILITIES/9oi-A Texas street/Denton,7% 76201
MEMORANDUM
TO: Tom Shaw, Purchasing Agent
FROM: Glenn A. Gary, Engineering Associate
DATE: September 12, 1994
SUBJECT: WASTEWATER TREATMENT PLANT EMERGENCY PURCHASES
On Thursday, August 22, 1994, 1 was called out to the Wastewater Plant to
look at the pump discharge header on the main raw sewage pump station. The
discharge header has moved and the pipe riser for pump No. 9 is leaking about
15 gallons per minute. The pipe riser section on pump No. 8 is also starting to
leak. It appears that during the new construction of the plant the total dynamic
head was changed on the forcemain. The change in head has caused the check
valves, which are non -cushioned swing checks, to slam when pumps turn on
and off. The slamming is so violent that it shakes the entire lift station, pulling
the discharge header apart. With this type of force being applied to the header,
failure is imminent.
If the discharge header breaks then the entire plant will be shutdown. Raw
sewage will discharge to the creek until the unit can be repaired, which could
result in fines from the EPA and TNRCC. There is an auxiliary pump station but
it shares the same forcemain as the main pump station. Also, there are no
isolation valves for the main pump station. Therefore, if the main pump station
is shutdown, the auxiliary station must be shut down. To fix this problem, the
project is divided into two phases. The first phase is to add an isolation valve
to the main station so that the main discharge header can be worked on while
using the auxiliary station to run the plant. The second phase is to solve the
slamming problem and to realign the pump header.
Page 2
Phase I must be done immediately or the City risks the entire Wastewater
Treatment Plant being out of service. Phase I consists of the following:
1. Purchase of 36" Plug Valve. I called the following manufacturers
to get quotes on:
a. 36" Plug Valve
Pratt does not make 36" Plug Valve
Clow does not make 36" Plug Valves.
M&H does not make 36" Plug Valves.
Dezurik - (El') - $19,988 - 10-12 weeks delivery.
Keystone (Municipal Valve) - $17,500 2 weeks delivery.
The Keystone valve was the lowest quote and the best
delivery time and is on order.
b. Bypass pump around the main pump station. The only way
to cut in an isolation valve is to take the main station off line
and use portable pumps with 4-12" parallel pipelines from
the main wet well to the grit structures. I have contacted
Rain for Rent, a company that specializes in portable
pumping. The estimated cost to bypass pump the plant is
$16,000. 1 will be receiving a firm quote soon.
C. Flanges butt straps and welding. The forcemain that the
valve is to be inserted into is reinforced concrete steel
cylinder pipe made by Gifford Hill. Gifford Hill will provide
flanges, butt straps and weld the valve in. The original
estimate for this is $2,880. 1 am still waiting for a quote
from Gifford Hill.
Labor other than welding will be handled by in-house forces.
If you have any questions please contact me at extension 7191.
