Mr. William MacKenzie Hilo Electric Light Company, Ltd. P. O. Box 1027 Hilo, Hawaii 96720

Dear Bill:

As you requested in your letter of December 12, 1966, we hav~ reviewed the proposed hydro development in Waipio Valley in the light of recent work that we have been doing for HELCO. We have not made detailed studies of the proposition and this does not seem to be justified at this time.

The proposal by Reed and Martin is for 1, 000 KW of firm power or 4,000 KW peak output at an installed cost of $900,000. This amounts to $900 per iirm KW and is quite a high price to pay for capacity.

The purchase of 1, 000 KW of firm capacity for a ten year period at the proposed rate of 15 mills per KWH does r~Oj; ~ppear to be economical for HELCO. The 1,000 KW capacity is not large enough to defer an investment in additional facilities in the future since the annual load growth of the system during the period 1970 -75 is 3, 500 to 4, 500 KW. The capacity of 1,000 KW is con­sidered firm at 100% load factor or 8, 700, 000 annual KWH. However, no pr'OVision is made for reserve in case the genera­tion is not available. Acceptance of the 1,000 KW at 100o/c load factor will require displacing energy on units already existing in your system which have energy costs of 6.2 to 10.6 mills per KWH.

The recently completed Power Purchase Study for HEL(;O dated Dec. 1ber 19, 1966 shows, in Table 2, the average cost of energy in 19::' to be 6.48 mills per KWH. On this basis, it would be reas --'c~able to conclude that the price for purchased power should not e...::ceed the average cost per KWH. Therefore, a price of .. approximately 6 mills would appear to be the maximum which HELCO could justify.

Mr. William MacKenzie January 16, 1967

The location of the Waipio Yalley with respect to existing system facilities should be considered~ We have not evaluated the cost of connecting this 1, 000 KW unit to your system.

A decision concerning the Waipio Valley development should also consider alternative methods of generation which would provide a comparable amount of capacity. It would appear that diesel units could be installed to produce energy at a lower cost than 15 mills per KWH and these would have the added advantage of a deg:ree of mobility inasmuch as they could be moved from place to place on the system as the need exists •

. Ii we ca.n provide any further information or comment on the pro­posed development, please let me know.

water development prospects at the New Plant Site

of Hilo Electric Light Co.

Summary

It appears practically certain that 15 to 20 million gallons of ground water

daily can be produced at the new HELCO plant site by means of two drilled wells

each 150 feet deep, or by means of an infiltration gallery or open sump 200

f·set long. Water developed by an infiltration gallery probably will have a

somewhat lower salinity and slightly lower temperature than that from drilled

weils, and this method of development po sea less risk of causing increase in

salinity of the ground-water body underlying the area. Additional water, to

the extent of as much as 75 million gallons daily total, almost certainly can

be obtained by increasing the number of drilled weils or the length of the in-

filtration gallery without jeopardizing the quality of water in the local

groundV':ater body.. The choice between the two methods of development should

depend largely on relative costs and engineering convenience.

PUmping test on cesspool

'nle cesspool$ about 8 feet in diameter, near the we8t edge of the property.,

was deepened to 39.5 feet below ground level (approximately 2.5 feet above sea

level). The bottom of the ~avation was approximately 5 feet below static

water level, which, however, variee with the stage of the tide. 6 jackhammer

holes, about 2 inche:s in diameter, were sunk about 8 feet below the bottom of

the excavation to incre~se the rate of water inflow.

On october 5 and 6 the cesspool was pumped at a rate of approximately

700 gallons par :ninute (1,000,000 gallons daily), on the second _day continuou~ly

for 5 hours. The water was delivered from the pump through a short, pipe into &

wooden flume, from which it was dumped on the ground surface 150 feet to .the

northw6e-t. Tt spread out to fonn a 0001 up to about 8 inches deep about 35 feet

across and 100 feet lOnR. from which it seeped into the .!n"Ound.

The water level in the cesspool excavation wae gradually drawn down

tion of pumping the water level recovered 7 inches in the first minute, 24

inches; ire 3~5 minutes, and at a. decreasing rate until full recovery was

attained in 13 mi:mtee. The recovery curve is ftlown on an accompanying

A 'Northingtor. verti~al turlir~e punlp (model 14 I'\T'I<'·)) was ir,3talled with

the botton of the unit 0.52 feet above sea level, th~ runT intdke thus beir,g

5ubn,erged only a little more than 5 feet during pUII.ping. The rUJr'j' di scharged

into a 12-inch pipe, in which a lO-ir:ch orifice plate was uiserted. A tap

for a manometer and prt;;ssure ga.ge wa::. inserted iL tho:; pipe about 2 feet to­

"ard the pLU!l1J frotl the orifice plate. The W2.ter was ther, led tr.rough a

lO-inch pipe and discbarged into tr,e cesspool neC.r tbe west edge of the

1Jroperty, 500 feet ir, a straight line frc,ru the well.

The pump D,stallation was comrleted on rovember 10, and a orief trial

made. On Nover-lher II the pump waf: run fron:. 09:35 tc 09:43 witt free dis­

charge onto the fY'CluIld adjacent to the well. The pumpin~ rate, as deter­

mined with orifice plate and manometer, was 4,66D gal/min. (6,700,000 g/d).

The dralfdo1¥n ir. trJe well was 4.1 ir:.ches, from a static head of 7.06 feet,

and recovery on cessation of pumping "as cor.mlete wi thin le or 15 seconds.

The pump was started" again at 10: 50 and run until 16:00, discharging

throu€;fl the oir'aline into the cesspool. The dynam:tc head, determined by

usinp the pre saure gage, was 117 feet. The r>umpir!" rate was apr'roJCimately

29500 gal/min (3,0(,0,(00 g/d~. Drawdown in the wel] wae 2.6 ird:es. On

stoppiIl[ the pump, rp.cC'very of the water .ievel ir. the v,ell was cor,l! lete

in 5 seconds.

'.

On November 13 the pump was started at 07:06, the water discharging

through the pipeline into the cesspool. Fluorscein dye (about 8 Ibs.) was

dumped into the cesspool to check on any possible return of water to the

well, although this was believed to be highly unlikely. The pumping rate

was again approximately 1600 gal/min. In 20 seconds the water-level draw­

down was stable at 2.52 inches. At 08:31 pumping was stopped to remove an

obstruction at the cesspool, and resumed at 08:38. \"aterlevel recovery on

stopping the pump was complete in 5 seconds. At 11:08 pumping was again

stopped to recaulk badly leaking joints in the pipeline, and resumed. at

11:23. Pumping was again suspended from 13:12 to 14:38 for the same pur-

pose. After that pumping was continuous until 08:00 on November 16. Each

time pumping was re sumed the drawdown was the same as the original, as closely

as could be determined from the pressure gage on the air line (which read

directly to O~l Ib/in2 and was estimated to 0.01 Ib/in2•

Water levels were read hourly throughout the 72-hour pumping teat, and

are plotted on the attached curve. They indicate a daily tide in the well

with an amplitude of about 005 foot, the lesser peaks of the local mixed

tide being effectually damped out.

~~linity ranged through the tests as follows:

Nov. 11, 10:30 - 40 ppm Cl- (3.8 gr/gal NaCl) 12:00 - ,24 " (2.3 11 ) 16:00 - 22 " (2.1 " )

Nov. 13, 07:10 - 56 " ( 5.4 " ) 19:00 - 10 " (1.0 " )

Nov. 1.4, 07:00 - 32 " 0.0 " ) 19:00 - 20 " (1.9 II )

Nov. 15, 07:00 - 22 " (2.1 " ) 19:00 - 22 n (2.1 " )

Nov. 16, 07 :00 - ;a:) " (1.9 " )

..

The salinity during the 72-hour pumping test is plotted on the same graph

with the water levels. During both the 5-hour test on l"ovember 11 and the

72-hour test the quality of the water improved during pumping as compared

to what it was just before pumping commenced.

The temperature of the water, measured at a leaking pipe joint ';ust

beyond the orifice plate, remained approximately 680 F. (measured with a

mercurial laboratory thermometer) throughout the test.

":ater level measurements were made hourly during daylight hours in

test well 3, drilled in August 1960. 1.l1is well is almost directly toward

the ocean from well 4, and thus approximately on the probable line of

water movement from well 4. No effect on water level in well 3 as a re­

sult of pumpinR well 4 could be detected.

The entire discharge, except for minor amounts of water lost at leaks

in the pipe line, was dumped into the cesspool excavation throughout both

the 5-hour and the 72-hour pumping tests. The cesspool returned the water

to the ground without difficulty.

Conclusions

With a suitable pump, well 4 will almost certainly produce 10,000,000

gallons daily of water with a salinity of about 20 to 25 ppm Cl- and a tem­

perature of about 680 F., wi. thout risk of causing salt incursion in the

area. Additional drilled welle spaced as far apart as feasible across the

south edge of the property can be expected to produce similar amounts of

water with similar salinity and temperature. The total estimated irmnediate

need of 15,000,000 gallons daily almost certainly can be obtained from two

wells, though a third stand-by well and pump probably is desirable from an

operational standpoint. If additional wells are cril1ed the water mig'ht be

somewhat improved in quality 'by reducine the derth to about 150 feet. If

6.

a test indicates inadequate yield at that depth, the well can be deepened

to about 200 feet, but should not go deeper than that.

A total yield of 50 to 75 million gallons daily probably will not cause

any important increase in salinity of the water, particularly provided the

water is returned to the ground-water body between the well field and the

coast. Reinjection of the water into the ground ia hi~ly recommended.

It call be accomplished either by means of negative wells operating in the

manner the cesspool did during the tests of November 11 and November 13-16,

or by infiltration from a ditch. If it is left unlined, the proposed oil

pipe-line ditch could serve in this capacity.

Approximately 10 million gallons of water a day probably could be ob­

tained from a sump or collection gallery 8 feet wide, 100 feet long, and

extending at least 5 feet below the average lo~-tide level of the ground­

water table. The salinity probably would be less than 10 ppm Cl-, and the

temperature might be as low as 66° F. The ditch or ~allery should run in

an approximately east-west direction. ~ending the gallery across the

southern edge of the property would increase the amount of available water

approximately in prorortion t c its length, and a series of shallow drill

holes into the floor of the gallery would increase its yield still further.

A total yield of 50 million gallons or more per day almost surely can be

obtained il. tt.is way_ h developl'lent of tllis sort would constitute even

less of a potential threat to the saline quality of the local ground-water

body than would the series of drilled wells mentioned above.

,.., I •

Pumping from the gallery or from sumps in it can be by means of

centrifugal pumps set in a pum}: chamber at gallery level, or by deep-lI'ell

type vertical turbines operated at the surface.

The choice of develo~t by means of p series of crilled ~lls, or

by means of an infiltration gallery, depends on relative costs and engineering

convenience. The choice should be made by the engineers, taking into con-

sideration the respective salinities and water temperatures to be expected

in each type of development.

The Pacific Science Congreee is over, and ! finally haTe time to tum again to TOur probleml

In the last f n days I have given it considerable study, and ha .... dis­cussed. it with both Mr. Doak Cox, formerly hydrologist tor the H.S.p.A. Experi­ment station, and Mr. D. A. DaTis, District C'reologist tor the U. S. neo10gical SurTe1, Ground ',Vater Branch. As a result, ! haTe the following cOlllTlents and reco.endations to make:

Firstlr, we are a little concerned about the unusual~ high head (leTe1 ot the water table) in the area ot your new plant site. Can ~u tell .. in detail who ran tne level. to the test holes on which the water-level measureaent. were baNd." whether or not the level line wa. cloaed, whether the reduction ot the field note. haa been checked" what benchmark was used as a startin&' point tor the leTel.!nc, and how that benchllark was establiahed (whether it was properlr tied to an actual determination ot mean ... level)?

Seoondl7, t.ald.n& TOur immediate needs to be appro.xim&tel1 15 JdlUon gallons ot water d&il.r, we teel confident that you can get that lIIIOunt ot water trca the (]h7ben~e"berl len. (the lens ot fresh water that overlie. the salt water that _turate. the ba_ ot the island) at your nn plant site. The best aeana ot develOJact _ •• probablT to be a row ot larp-diaeter (ca. 16 inch) drilled welle, preterablr along the side ot your propertr next to Pohaku st., the ... well. bein, spaced as tar apart a. possible within the boundariee ot JOur propertr. It ia our beet guese that the. weU. should utend to a depth ot about 200 tNt below eround surtace, to obtain adequate draft potential and. ainiJaua water temperature and. yet not be 80 deep ae to inrlte alt water in­curaion tro. below. Probably the water temperature will be about 650 1"., unle •• 001'11&1 ground.-_ter condition. are disturbed br ~lcanie heat. ~ch .elle pl'Obab17 will yield 3 million gallons daily or more each, 80 that 5 welle would give 10u the presentlY' required amount ot water, though you probablr would want 110M additional .. lle as standbys in case ot pump breakdowns. '!he Y.l.1nitr ot the _ter lIhould be very low.

2. o

Mr. Jitalo Niwao, Sept. 15, 1961, cont1nueci:

'!he above are all tentatiye opinions buecl on general. u;perience ill the Hawaiian Ial..aDd., and they d.linite17 aboulcl be checked. with a teat _11 betore tinal recommendations are JlAde. I theretore reca..end that 1QU drill a 16-inch well to • depth ot a:x> teet and. inet&l.l in ita pUIIp capable or deUvenn. at leaat 3 aillion sallona ot water dally, to teat the 11e1d 01 the well and the t.aperature and. Nl.1nity ot the water. illowance Ihould be Mde tor a drawdown ot at leallt 15 teet, though lt ... y not be that .ch. The tellt, at .ax1a1. PWllping rate, Ibould be run at least 72 hour.. '!'he teet well can later be used as one ot the aetual producing well ••

I turther recoaamd that surface casin, be set in the dense central. part of the aa laYa now penetrated 46 t.et below the ~ace in teat hole 2. It the well is cased off to that level, the denae aa la,..r will help prevent the .am used water returned to the gNUnd fl"Oll reenterin« the producln, part ot the aquiter and raiaing the temperature of the water being pwaped fro. the .. 11.

'l'blrd.ly, if Bechtel Corporation's projection of your tuture needs at about 70 mil110n gallons da1171. correct, we belieYe it ls quite unllke1y that you can ~t that wch fresh water at your aite'without doin~ serious d&IIa,. to the Chyben-Herzberg len.. It is, however, practiaa1.1y certe.1n that you can get almost unlimited amount. of salt water by drilling through the len. and producing the salt water fro. beneath it. If the .. 11 is eased off throUih the lens, pumping fro. below the lens mould not Hriousl1 di .. turb it. 'lbe ealt water will rise in the well caaing approximately to sea leyel, an:i your PUllLping lift would be approximately the distance to .... level plue the efrective drawdown in the well. W1 best guees is that at a depth ot 400 feet the t_perature of the water is about 700 .,., and that the ealinity is approximate17 that ot water at the aa.me depth in the open ocean.

Obviously, this aleo lIbould be checked betore developamt. plans are baaed on it. It it is considered desirable to tellt now tor tuture plann1nc I auggeat. " second teat bole extending to about 400 teet below ground 1e..,..1. Th. II&i.n purpose of this hole would be to obtain data on Mlinity and temperature ot the water. .l full proclu.etlrltr teat is not ot pat. iaportance in this ca .. , be­eaUN it the 71elcl ot a ltOO-toot well proves inadequate it can be increased indetinitely by deepcUn, the well, the only real llait being pract.1eal drill­ing depth. In fact, the COlt ot deeper dri1lin, abould be to eo.e degree otf­set by alighUr lower taper&ture ot the _tel'. Since a aall production i. adequate for the teat ot salinity and temperature, this teat well can be ot IlUch 8II&l1er di .. eter than the other one auggeated above, and need only be large enouch to take the pump and re.uaite casin,. ('nle driller can aupply figure. on this.)

k'ftct: Note. on Likelihood Gf Developitl. 50, tlGe .,.. from Ground .. Water Sourcel at HUo .... . ...

A. you !'eque.ted, Mr. McClure ha. re'riewed the Iround"wllter data tOl' the HUo area with relard to the po.sibUity of dev.lopin, a ".,Wld .. water .ouree that would yield about 50,000 aallCl1ft. 01 ~at.r per minute fer cooUnl purpo.e. at the propo.ed new locatioll lor the kUo plant.

The data from the publication by StearA. and. MaeDonl.ld, ".U.la..t in 1946, indlt:at •• that at that tittle there wel'e a'bout Ilx exi.ting weU. ill the vicinity of the new plant .ite. The.e were 01 the Maul type or roek eollector, and the maximum producer yielded about 1 m.il1iofJ la11on. per day or about 1/10 of the requirement for thil plant.

In order to .ucce •• fully evaluate whether or ftot We can develop a Iround~water supply of adequate capacity in the HUo ai'~a, ce't'taln. factual data are tequired. The.e include:

1. An up .. to .. date around-water iftventbry of the area:

<a) Lotation of exiltinl welh, ehternl. &te.

(b) Elevation of ext.ting weill, elltern., etc.

(c) Their yield and companion drawdown.

(d) Depth to aquiter.

(e) Quality.

(f) LOI and .urfaee l.ololY of exiltin. welll.

o o Mr. J. R. Kiely - 2 - July 21, 1961

2. An aquifer performance test to determine yield verSlus clrawclown:

(a) The test should be made with pumps capable of delivering at least 10,000 gallons per minute.

(b) Teet should start with deli very of about 2 ~OO gprn, then 5000 gpm, then 1500 8pm, and fitlally 10,000 gpm or greater if well will yield.

(e) Effect of test on neighboring wells, water supply tunnels. etc.

(d) Test should be run at least 72 hours.

(e) Effect of salt water intrusion resulting hom test.

The problem appears straight forward providing balie data are a.vailable and phys ieal arrangements for a suitable test can be made.

It may be that local agencies there, such all the Hawaiian Division of Hydrography or U. S. Geological Survey office might have the necel!lsary basic data. With presently available information, and using data 15 years old, it appears that a ba.ttery of wells capable of deliverying 50, 000 gpm h unlikely, or if possible, would adversely affect surrounding Iround-water supplies.

We will await further instruction. from you as to what additional .tep. you may wish to take.
