Part 3.00 — Execution <br />3.01 Installation <br />protect <br />A. The structural stormwater treatment system shall be constructed according to the sizes shown on the <br />drawings and as specified herein. Install at elevations and locations shown on the drawings or as <br />otherwise directed by the engineer. <br />B. Place the pre -cast base units on a granular sub -base in accordance with the governing city's <br />requirements. The granular sub -base shall be checked for level prior to setting and the pre -cast base <br />sections of the stormwater treatment system shall be checked with a horizontal level at four <br />quadrants after setting. If the slope exceeds 0.25 %, the base section shall be removed and the <br />granular excavation floor material re- leveled. <br />C. The ecoStorm Stormwater Treatment System is designed to be watertight. The final installation must <br />guarantee a watertight structure either through infiltration or exfiltration testing. Failure to achieve a <br />watertight structure is grounds for rejection. <br />TODAY by <br />building forTOMORROW <br />END OF SECTION <br />ecoStorm <br />Page 4 of 4 <br />www.royalenterprises.net • 651- 462 -2130 • 800 - 817 -3240 <br />3.09 <br />
