After 50 years in service, the 3 meter diameter surge shaft for the 122 Mega Watt Middle Fork Hydro Power Plant had deteriorated and was cracking, perhaps due in part to seismic activity. The water leakage was believed to be seeping into the hillside and at one point had been named as the cause of [...]
The Hyatt Place Hotel built at Reno/Tahoe International Airport in 2009 required utility trenching to 25 feet, which was below the static groundwater level of 11 feet, so dewater was required. Laboratory test results found serious contaminates from hydrocarbons and heavy metals which required significant Groundwater treatment and remediation. The earth work created high levels [...]
Hanna Court was a 50.69 acre site where a 411,106 sf Warehouse and Distribution Facility was being developed. This site had sensitive habitat due to the 1.3 acre wetland in the vicinity. ATS treated the stormwater runoff using Chitosan Enhanced Sand Filtration (CESF). The runoff was collected in various retention basins through the 50.69 acres [...]
ATS was hired by S.J. Louis Construction to conduct pH adjustment for hydrostatic testing. ATS pumped down existing pipeline effluent, corrected pH and discharged. Citric Acid was injected as needed to depress the pH value to required water quality standards. A total of 1,093,030 gallons was monitored, treated, and discharged into Skunk Creek.
ATS was brought on by FRWA to conduct pH adjustment for hydrostatic testing. ATS installed a 1,000 GPM treatment system along with an 18,000 gallon open top tank. Water was pumped from a drain vault north of Goose Creek through ATS monitoring and Treatment System and into an 18,000 gallon tank. Citric Acid was injected [...]
ATS was contract by Martin Brothers Construction to install an active treatment system for the stormwater runoff from the haul road of the Folsom Dam and the adjacent areas. The stormwater was treated for turbidity using Chitosan Enhanced Sand Filtration. ATS set up a system that collect the site runoff and conveyed it to the [...]
The Folsom Dam Auxillary Overflow project is a 110 acre site located at the Folsom Dam in Folsom, CA. ATS has set up a 3,115 GPM Chitosan Enchanced Sand Filtration stormwater treatment system. Due to limited amount of working area this site has come along with some storage problems. To solve this problem ATS had [...]
ATS, Inc. was contracted to setup and run a Stormwater Treatment Systems for Eskaton Village located in Placerville, CA. Eskaton Village was a 19 acre construction site for a retirement community. ATS treated the stormwater using a 600 GPM Chitosan Enhanced San Filtration (CESF) system. Due to pH being lower than water quality standards ATS [...]
ATS, Inc. was contracted to treat for colloidal clay turbidity problems associated with the drilling and development of a community drinking water well. Well depth is 1,100 feet and turbidity levels were expected to measure over 1,000 NTU. Chitosan Enhanced Sand Filtration was selected as a safe, cost effective method. Developing the well required the [...]
ATS was hired to set up a Stormwater Treatment System for the Elk Grove promenade which was a 110 acre commercial property located in Elk Grove, CA. ATS design was for three (3) ATS systems that treated a combined 1800 gpm. The system was designed to monitor for both turbidity and pH. ATS treated from [...]
