Section 02731 <br />Irrigation Water Well <br />3.2 Preparation <br />A. Protect structures near the well from damage. <br />B. Conform to well and wellfield requirements of the authorities having jurisdiction. <br />3.3 Well construction <br />A. Drill well as required to provide required water quality and quantity. The Contractor <br />shall perform water chemical analysis test as necessary during drilling in order to <br />locate the water bearing formation that yields water with an acceptable iron and salt <br />content. The Contractor shall make all reasonable efforts to obtain water on the site <br />than has less than 0.3 -ppm iron content and less than 300 -ppm salt content. Provide <br />information to Architect/Owner as noted in paragraph 1.5 of this section. <br />B. The well casing shall be aligned and plumb. <br />C. Provide permanent casing with a temporary well cap. Coordinate well cap construction <br />with pump system installer. <br />D. Well Capacity: It shall be the responsibility of the Contractor to construct a well of the <br />type and size so that the water quality and capacity specified in this section will be <br />produced continuously. <br />3.4 Tolerances <br />A. Maximum Variation From Plumb: In accordance with ANSI/AWWA A100. <br />B. Maximum Offset From True Position: 1" <br />3.5 Cleaning <br />A. Clean work under provisions of 01700. <br />3.6 Well development <br />A. Develop well by such methods as will effectively extract from water -bearing formation <br />maximum practical quantity of sand, drilling mud and other fine materials in order to <br />bring well to a maximum yield per foot of draw down and to a sand -free condition. <br />B. Perform work in a manner that does not cause undue settlement and disturbance of <br />strata above water bearing formation nor disturb seal affected around casing. <br />C. Continue well development until water pumped from well at maximum testing pumping <br />rate is clear and free from sand and other debris larger than .030" in diameter. <br />1. Water shall be considered sand -free when no samples, taken during test pumping, <br />contain more than 2 parts per million of suspended solids by weight. <br />2. The Contractor shall submit a certified document from an approved testing <br />laboratory to the Architect and Owner indicating the results of the "Non -Filterable <br />Residual" (total suspended solids) test, EPA Manual 160.2. <br />3. Sufficient water must be filtered in order in insure a detection limit of less than 2 <br />PPM (mg/1). <br />4. Maximum iron allowed in the well water shall be less than 0.3 PPM. <br />3.7 Testing well for plumbness and alignment <br />State Road 60 and 43rd Avenue <br />
