CALCULATING A BUDGET WATER USE VALUE

The actual water applied in 2018 was 39,543, 543,711 g 711 gallo lons, making the existing irrigation system 61.06% e

06% effici cient ent.

• The new irrigation system could apply up to

30, 30,182, 182,443 43 g gal allons p per er day.

• This would equate to a theoretical water use

reduction of approximately 23.

23.7% over

er 2018 2018 reported ed w water ter usage.

EXPECTED EFFICIENCY OF A NEW IRRIGATION SYSTEM

LOS ALAMOS COUNTY GOLF COURSE

• Edge-to-edge spray irrigation system, covering

approximately 79. 79.00 acr 00 acres es of turf.

• Designed for long term maintainability and effective

irrigation control.

• It is estimated to require approximately 1,

1,500 500 valve- in-head style golf sprinklers.

• Proposed irrigation control system will be a

computer-controlled system.

PROPOSED DESIGN FEATURES

LOS ALAMOS COUNTY GOLF COURSE

• Large mainline hydraulic structure capable of

applying the maximum daily evapotranspiration rate of 0. 0.26” 26” within an 8-hour hour water window.

• All golf sprinklers will be “electric-valve-in-head”

which will enable them to operate individually, allowing for precision control and management when needed.

• Quick couplers located at greens and tee complexes

facilitates easy access locations to plug in hoses and utilize a high-volume water connection.

PRELIMINARY COST ESTIMATES

Based on a per-sprinkler base cost of $1, $1,250 p 250 per er sprin rinkle ler, plus a “premium” of between 15% and 30% for the likely scenario of perceived “rock- trenching” conditions, the estimated installed cost of the basic golf course irrigation system is expected to range between:

$2,157, 157,000 000 ($1,438/per sprinkler)

AND

$2,437, 437,500 500 ($1,625/per sprinkler)

Plus costs of taxes, fees, permits, options, etc.

ADDITIONAL DESIGN CONSIDERATIONS

Turf rf R Reductio ions:

• There are approximately 3.

3.61 acr 61 acres es of fairway where some potential areas of turf may be reduced.

• This could result in a potential annual water

savings of approximately 1, 1,103, 103,17 178 g 8 gal allons.
