36°34'43.9"N, 118°03'19.4"W.

Description:

1. Bishop Creek Wastewater Treatment Plant

a) The Bishop Creek Wastewater Treatment plant is operated year-round and treats wastewater from the community of Aspendell (year-round) and Forest Service campgrounds usually from April through October. Flow to the treatment plant varies from 10,000 gpd to 35,000 gpd. The collection system is primarily gravity fed, except for the one lift station at Forks Campground.

Waste from an RV dump station at the Four Jeffrey Campground discharges through a settling tank to the treatment plant.

b) Flow into the treatment plant goes through a grinder and then gravity flows into the upper treatment pond. The upper pond then gravity flows to the lower treatment pond. Each pond has two 2hp/460 V aerators. Both ponds are lined with a 30-mil two-ply Hypalon rubber with single-ply nylon reinforcement.

c) Effluent gravity flows from the treatment ponds to the discharge pump vault. There are two 60 hp/90 GPM discharge pumps that alternate cycles. The effluent is pumped over the hill to the west and into one of three infiltration/evaporation disposal ponds.

d) The Contract Operator shall perform ongoing and preventative maintenance activities related to the operation of the discharge pumps such as regularly lubricating pumps and motors, observing pump motors routinely to detect unusual noises, vibrations or excessive heat, inspecting, adjusting and cleaning pump seals, packing glands and any mechanical seals when necessary.

e) Board Order No. 6-00-16, WDID No. 6B140705002 allows the Inyo National Forest to discharge treated wastewater from the Bishop Creek Wastewater Treatment Plant onto National Forest Land within the State of California.

2. Rock Creek Wastewater Treatment Plant

a) The Rock Creek Wastewater Treatment Plant is usually operated from April through October and treats wastewater from Forest Service campgrounds, Forest Service fire station, Forest Service dump station, and Rock Creek Lodge/Resort. The sewer collection system has 9.0 miles of sewer lines. Flow to the treatment plant varies from 5,000 gpd – 20,000 gpd. The collection system is primarily gravity fed, except for the two lift stations at Rock Creek Lake Campground and Rock Creek Group Campground. Waste from the RV dump station at the campground discharges through a settling tank to the treatment plant.

b) Flow into the treatment plant goes through a grinder and then gravity flows into the upper clay-lined facultative oxidation pond. The upper pond has one 1.5hp/200 V aerator. The upper pond gravity flows to the lower unlined infiltration/evaporation disposal pond. The lower pond does not have an aerator and usually contains little to no effluent due to effective infiltration/evaporation.

c) There are two groundwater monitoring wells downhill from the lower pond that are used to take the annual groundwater monitoring sample.

d) Board order No. 6-92-107, WDID No. 6B260705002 allows the Inyo National Forest to discharge treated wastewater from the Rock Creek Wastewater Treatment Plant onto National Forest Land

3. Convict Lake Wastewater Treatment Plant

a) The Convict Lake Wastewater Treatment Plant is operated year-round and treats wastewater from Convict Lake Resort (all year) and Convict Lake Campground from April through October. The waste collection system has approximately 11,800 linear feet of 6” and 4” PVC wastewater pipe.

Wastewater flow to the plant ranges from 5,000 gpd to 25,000 gpd. All wastewater goes into a lift station below Convict Lake Resort, where two grinder/pumps discharge wastewater to the upper pond of the treatment plant.

b) Wastewater gravity flows from the upper treatment pond to the lower treatment pond. Both treatment ponds are lined with a 30-mil two-ply Hypalon rubber with single-ply nylon reinforcement. The lower pond level is pumped down twice per year (Spring and Fall). The lower pond effluent is pumped uphill to irrigation fields via a discharge pump at the treatment facility.

Effluent travels to the irrigation fields through 1,200 feet of 4” PVC pipe.

c) In the spring as soon as the ponds are ice free, the aerators are placed in the ponds. The upper pond gets two 1.5 hp/200 V submersible aerators, and the lower pond gets three ¾ hp/230 V submersible aerators. It usually takes a week or two for the aerators to bring down the BOD in the wastewater to the required Discharge BOD of 45 or less. Once this level has been reached, the wastewater can be discharged.

d) Board order No. 6-95-97, WDID No. 6B260705001 allows the Inyo National Forest to discharge treated wastewater from the Convict Lake Wastewater Treatment Plant onto National Forest Land

4. Eastern Sierra Visitor Center, Lift Station

a) The lift station operates year-rounds and pumps wastewater from the visitor center to a wastewater treatment facility (operated by others). The lift station has a wet well capacity of approximately 3,000 gallons. It has two 10 HP submersible pumps, an electrical control panel and a vault box for the discharge pipes.
