RAIN HARVESTING SYSTEMS

Enviremedial Services offers several different rain harvesting models, to help meet the varying needs of our customers. 

In March of 2018 we installed our first Solar Rain Harvest to Potable system on United States Army Garrison Fort Buchanan, in Puerto Rico. This off grid system supplies clean water to the Welcome Center on base, and has been completely self sufficient since installation.

 

RAIN HARVEST TO VEHICLE WASH SYSTEM

The ESI Rain Harvest to Vehicle Wash Rack System Model 3050-RH2WR-01 is designed to collect vehicle wash water and rainwater from wash pads and trench drains and store, treat and distribute water back into the vehicle wash reclaim system for wash operation reuse. 


Collected water is stored in the first collection tank which has a 4,000-gallon capacity. The first stage of treatment is through a coconut shell carbon absorber and then through a .35-micronabsolute pleated filter housing. From there the treated water is held in a sealed polypropylene tank. As water is required from the distribution point of the system, generally the pressure washers, pressure in the final treated water bladder tank is plumbed through to the pressure washers. When pressure drops to a predetermined set point in the bladder tank a multistage booster pump is activated and water from the treated water storage tank is pressurized and the bladder tank is re-filled. 


These systems are equipped with advanced remote monitoring systems connected to the Internet via GPRS cellular modems, with all remote access and control for service support by Enviremedial services and tracking of the entire system for the end user. Parameters such a filter status, carbon status, chlorine levels, tank levels, flow, totals and many other parameters are tracked on the telemetry system. Graphing and trending are also readily available via the web interface. 

RAIN HARVEST TO POTABLE

The ESI Rain Harvest to Potable Systems are designed to collect rain water from collectable areas and store, treat and distribute water to buildings for full facility potable use. These systems have also been implemented in areas where natural disasters have caused the potable water supply to be questionable and treatment is required to ensure safe water for consumption or other potable uses. 


Collected water either from rain or from distribution sources that need further treatment are collected in the first collection tank(s) which have 4,000- to 12,000-gallon capacity. The water in the tanks are initially treated with ozone to start the treatment and disinfection process. From there that tank is plumbed into the treatment and off grid power skid. The first stage of treatment is through a coconut shell carbon absorber and then through a .35-micron absolute pleated filter housing. From there the treated water is held in a sealed polypropylene tank. As water is required from the distribution point of the system, pressure in the final treated water bladder tank is plumbed through a chlorine injection vessel to provide .5 to 1.5 mg/L of residual chlorine in the water. When pressure drops to a predetermined set point in the bladder tank a multistage booster pump is activated and water from the treated water storage tank is pressurized and the bladder tank is re-filled. 


The entire system is powered by an off grid solar system with large backup battery storage system and pure sinewave inverter system that provides continuous power to the treatment system control and telemetry system. The power generation system can also accept shore power or generator power as a backup to keep the batteries charged and the system running if required. These systems are equipped with advanced remote monitoring systems connected to the Internet via GPRS cellular modems, with all remote access and control for service support by Enviremedial services and tracking of the entire system for the end user. Parameters such a filter status, carbon status, chlorine levels, tank levels, flow, totals and many other parameters are tracked on the telemetry system. Graphing and trending are also readily available via the web interface. 

Depending on feed water other pre-treatment or post treatment modules can be added to the system to ensure excellent water quality for feed a facility or distribution points in a disaster area.

OPERATIONAL BENEFITS

  • The system is designed for on-demand operation with single pass treatment. This allows for operation for multiple days where solar generation is low, and no shore or generator power is available.

  • First flush technology to clear and rinse roof surfaces / gutters of debris and other pollutants for collection in the 1st stage tank. 

  • Remote Telemetry: Remote Telemetry alerts ESI service personnel of any out-of-normal parameters. This feature is instrumental in the achievement of 99% uptime for all our rain harvest systems. Oftentimes, issues with the system can be diagnosed and corrected via the Internet saving the cost of service calls and time lost while a wash rack is non-operational.

  • Maintenance and operation of these systems are very easy and consumable materials are available from a wide range of sources, to ensure the system can be serviced and operated.

  • Transportable and Re-locatable: The ESI Rain Harvest System is fully transportable when relocation is required.

  • ESI provides monthly or quarterly preventative maintenance and inspection services by certified, trained technicians.

  • Systems are configured in a variety of ways depending on the mission. They can be built in to ISO shipping containers, deployable containers of various types specified by the customer, and self-contained skids such as shown above or containerized systems.
