ADDITIONAL CONSIDERATIONS IN THE DESIGN,
INSTALLATION, AND OPERATION OF HOLDING TANKS
Item
Consi dera ti on
Sizing
Liquid holding capacity >7 days
wastewater flow generation. Minimum
capacity : 1,000 gallons.
Discharge
There should be no discharge.
Alarm System
High water alarm positioned to allow at
least 3 days storage after activation.
Accessibility
Frequent pumping is likely; therefore
holding tank(s) must be readily accessible
to pumping vehicle.
F1 otati on
Large tanks may be subject to severe
flotation forces in high groundwater areas
when pumped.
Cost
Frequent pumping and residuals disposal
results in very high operating costs.
Assessing the reliability of wastewater modification methods is a com-
plex task which includes considerations of a technological, sociologi-
cal, economic, and institutional nature. Major factors affecting
reliability include:
1. The actual wastewater characteristics prior to modification
compared to the average.
2. User awareness and influence on method performance.
3. Installation.
4. Method performance.
5. User circumvention or removal,

All work shown on the "M" & "P" series drawings and 15000 series specifica-
tion is to be provided unless otherwise stated.
The drawings and specifications are complementary to each other. What is
shown' on one is as binding as if called for in both. The mechanical
drawings are generally diagrammatic and are intended to show mechanical
details in a schematic fashion. Do not scale mechanical drawings. Exact
locations are not shown unless so indicated or specifically dimensioned.
Typical connection diagrams are schematic and do not show the actual physi-
cal arrangement of equipment. The plans do not necessarily show complete
details of all the features which may affect the mechanical installations;
however, it is the intent of the contract documents to provide a complete
and satisfactorily working installation.
Submit in writing to the Architect for review details of any necessary or
proposed departures from these Contract Rocuments and reasons therefore, as
soon as practicable and within 30 days after the award of the Contract.

adjacent to the feeder connection and shall be injected through a cor-
poration cock, hydrant or other connection ensuring treatment of the entire
line. Water shall be fed slowly into the line with chlorine applied in
amount to produce a dosage of 40 to 50 parts per million. Porti6ns of the
existing mains which have been connected to a new line or otherwise con-
taminated by construction shall be included in the system being sterilized.
A residual of not less than 10 parts per million shall be produced in all
parts of the line at the end of a 24-hour retention period. During the
chlorination process, all valve operations shall be performed.
Final Flushing: After chlorination the water shall be flushed from the
lines at the extremities until the replacement water tests are equal, che-
mically and bacteriologically,, to those of the permanent water supply.
Upon completion of sterilization, certify to the Architect in writing the
specified sterilization .has been performed.
Heating System: After above specified flushing, draining and refilling,
boil out heating system, for a period of four (4) hours, with water con-
taining I lb. Trisodium Phosphate for each 60 gallons of system capacity.

ces. The total volume of water in the well will be estimated, and a con-
centration of chlorine to 5D PPM for 24 hours shall be added for
disinfection of the well. Hypochlorite, in solution form, may be intro-
duced directly into the well by using gravity, pump or drip feeders. After
chlorine has been added and allowed to stand for a contact period of 24
hours, the well will be pumped to waste until the residual chlorine is less
than 1.0 PPM. Provide certification. All tests and analysis shall be in
accordance with applicable locat, State and Federal regulations.

masonry work for installation of electrical fittings.
Locate boxes in masonry walls so that only a corner need be cut from masonry
units.
Do not use sectional or handy boxes.
For boxes mounted in exterior walls make sure there is insul.ation behind
outlet boxes and vapor barrier is adequately patched to prevent condensation
in boxes or on building surfaces. Seal all conduit penetrations with silicone
sealant in each box installed after all conductors have been installed.
For outlets mounted above counters, benches and backsplashes, coordinate loca=
tion and mounting heights with built-in units. Adjust outlet mounting height
to agree with required location for equipment served, to avoid interference
with casework and to coordinate with other building features.
All boxes shall be mounted square and plumb. Boxes mounted at angle to true
horizontal, vertical and/or building lines shall be adjusted or removed and
reinstalled completely at discretion of Architect without cost to ~wner.
