Coalville City now produces SAFE, fine quality, rich composts and yard mulches for home or commercial use. These products are a wonderful
soil amendment for your lawn, flowers, even in your home garden.
Process: These products are produced in accordance with State and EP A guidelines to be safe for home use. This is accomplished by mixing the treated biosolids from the plant with wood chips, bark, green yard waste and straw and forming the mixture into piles. These piles are turned frequently. High temperatures are allowed to build up within the piles by the activity of microorganisms which stabilize the mixture and give off heat. During the first phase, the temperatures within the piles are raised to over 135 F to kill any possible pathogens which mayor may not be present. These temperatures are maintained for over two weeks. Also during this phase the temperatures are allowed to climb even higher to destroy any weed seeds. The piles are then allowed to cure several months, resulting in a very stable end product that has a pleasant earthy smell. Each pile is sampled and tested for pathogens to insure it is safe before it is made available.

Facility: The facility is a "state of the art" water reclamation facility and has received many awards from USEPA, even a National USEPA Award, as well as Water Environment Association of Utah.

BENEFITS OF USING COMPOSTS AND MULCHES
Compost is a wonderful soil amendment with some fertilizer value. It is derived from the natural decomposition of leaves, plants, manures, and biosolids by microorganisms. The end result of this process is a dark, crumbly, earthy smelling material called compost.
Not all composts are alike. Composts originate from a variety of sources, therefore, the quality and use of the composts vary. Generally, if compost resembles soil, it can be used in potting mixes, as a garden soil amendment, and in turf applications. If the light colored and composed of larger amounts of wood chips, bark or straw, it should be used as mulch.
Composts improve the aeration and drainage of heavy clay soils, Improve water-holding capacity of sandy soils, and increase the ability of all soils to retain nutrients. Using compost can improve turf performance and soil quality for gardens, vegetables, flowers, etc.. Composts can aid in reducing surface crusting and compaction. Composts contain organic forms of plant nutrients which are released as microorganisms break down the material. Compost nutrients become available to plant roots slowly and are less likely to be lost by leaching. These improvements promote faster turf establishment and better rooting, Improved stand quality, and reduced fertilizer needs.
Mulches reduce moisture loss from soil and promote rooting near the surface. Greater rooting near the surface increases water, nutrient, and oxygen absorption, leading to healthier plants. Mulches can also moderate surface soil temperatures, control annual weeds and grasses, reduce compaction and the need for tillage, decrease runoff and soil erosion, protect the trunk of woody vegetation from mower damage and allow easier movement through landscapes and gardens during wet periods. The properly selected mulch also adds visually to a landscape, and can be used to direct human movement.
