The quality of the water has generally been <br />good, except for some turbidity occurring in the spring. There is no raw water or <br />treated water storage, except that which occurs in the pipeline system. Usage <br />amounts are unknown, but it is believed minimum usage occurs in the late spring <br />and maximum usage occurs in July and December. Water shortages have not <br />occurred. <br /> <br />The system currently serves about 40 single family residences, of which 17 are <br />occupied year-round. There are no multi-family or commercial customers. At <br />ultimate buildout, the system must serve 179 units. Plans are under development <br />to construct a new raw water treatment facility. <br /> <br />Sewage Treatment <br /> <br />The Meridian Lake Park Corporation uses an aerated lagoon and polishing pond in <br />one cell with a baffle wall divider. It holds a total volume of about 0.358 MG. <br />The existing rated plant capacity is 0.014 MGD, and average peak monthly flows <br />are currently 0.014 MGO. <br /> <br />A Colorado Department of Health Cease and Desist Order is in effect due to BOD <br />and fecal coliform violations. The main deficiency of the lagoon is inadequate <br />hydraulic capacity or volume to properly treat the wastewater. A second <br />deficiency is that there is only one lagoon separated into two sections by the <br />baffle wall. It would be desirable to have a second lagoon separated from the <br />first by an earthen embankment. This would allow taking the first lagoon out of <br />service for cleaning and repair. State regulations require a minimum of two <br />aeration cells and one polishing pond. An aerated lagoon cannot achieve a low <br />level of ammonia removal; but this facility should handle ammonia removal unless <br />future growth is excessive. Also the extreme winter temperatures slow down <br />bacterial action and deep snows interfere with aerator operation and access to the <br />site. The facility discharges to Washington Gulch and uses chlorination and <br />dechlorination. Recent studies have recommended replacing the plant or piping <br />flows to a downstream facility (I.e. at Mt. Crested Butte). The Mt. Crested Butte <br />Water and Sanitation District has received and accepted a petition for inclusion <br />from Meridian Lake Park. RTW has projected average peak monthly flows of <br />0.028 MGD by the year 2013 and 0.036 MGO by 2033, indicating a need for <br />significant plant enlargement. <br /> <br />62 <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
