The required fire flow based on Appendix B Nevada Fire Code is as follows: a.
Existing building
5,234 sq.ft.
— required fire flow 2,250 GPM for 2 hours duration b.
New building
11,000 sq.ft.
— required fire flow is 2,750 GPM for 2 hours duration
NOTE: A 50% reduction in the required fire flow is permitted with the building is fire sprinklered
(see NAC B 105.2)
ASSUMPTION: The 11,000 Administrative Building will have fire suppression sprinkler installed.

The geo-solution for the Calvada Eye pond is reconstruction and is the best option for stopping a leaky pond. The pond must be drained, repaired and then sealed with 2,000 psi concrete slurried with 35% Montmorillonite Clay material.
Materials for Pond Remediation.
Discussion:
Review of Saponite (Montmorillonite)
Recommended Material:
Saponite is a soft material also known as Soapstone. When finely prossed into a power material and bagged it is used widely witin the drilling industry. Locally IMV mine sells the processed product under the trasde name “GEL”. Gel has near perfect cleavage (.001), and a Specific Gravity of 2.3. The CONVERSE CONSULTANTS Geotechnical Data Report and Laboratory results with comparisons of similiar products provides the following summary of saponite characteristics;
Sample C.
Processed magnesium rich saponite from IMV Mine, Amargosa Valley.
Expansion 80% that of Wyoming bentonite ie., 20 times.
Intended use as pond sealer: EXCELLENT
SAPONITE (GEL)
Sample C.
Processed magnesium rich saponite from IMV Mine, Amargosa Valley.
Pumping Viscosity: EXCELLENT
Availability: EXCELLENT
Transpotation Cost: MINIMAL
Application Recommendation, The saponite “GEL” product should be an addmixture to a batch design 2,000 psi grout mix. See attached local batch design.

BENTONITE (MONTMORILLONITE)
Wyoming bentonite clay is a premium material unique to Wyoming. This bentonite is highly expansive in water, 25 times and provides a near impervious barrier to water.
Texas Sodium Bentonite is a less desirable material in part because its properties provide less expansion therfore requiring application of more material and a slightly higher porousity.
Note: Bentonite is cheap. Transpotation is expensive.
Locally available material: LEVYNE (ZEOLOITE)
Amargosa Valley, Ash Meadows, ZEOX MINERAL MATERIAL CORP., produces a graded material which is marketed primarily as kitty litter.
A different mineral group than bentonite, Zeolite has very good properties.
The high cation exchamge capacity (C,E,C,) of zeolite makes it uniquely suited for various applications in water treatment. The first fullscale project to utilize zeolite was the Tahoe Truckee Sanitation Agency. Their use removed ammonia, and hydrogen sulfide and the resultant bad odor.
Zeolite may be colored blue-green for esthetic value
Note: Bulk Zeolite is cheap. Transpotation cost is minimal.
Reconstruction Means and Methods
Task 1.
Drain existing pools.
Task 2.
Remove deposited organic material of an offensive nature
Task 3.
Add +6.0 rock to pond bottom.
Task 4.

DISCUSSION:
The site will require a well capable of producing water for public consumption, landscaping and fire suppression.
The existing well on-site is an agricultural use well developed in 1964. Historical records indicate a water table of 58 ft.
depth. The well does not have a sanitary seal at 50 ft. depth. The age of the casing suggests a new cased well be should be considered and developed for its intented use.
The permitting and documenting is government use and should not pose any unusal conditions for the engineering design.
We propose the following estimate of Costs;
1.1
Well design for an allowable 240 gpm rate, 60psi well production.
$ 9,500.00
(1) Drilled well, 301, ft depth 8”casing with 50’ sanitary seal
