Evans Co-op Water Pumping Station Project – Epping NH

HAWSCO was contracted by Edgewater Strategies and CSA Environmental to completely replace the Water Distribution System and Build a complete new Water Pumping Station at the Evans Coop in Epping, NH.

The Distribution System portion consisted of installing roughly 1400 linear feet of new HDPE Water Mains, associated Gate Valves, all Curb Valves and new Service Connections to all existing 19 Units. The entire Coop was loamed and seeded in the affected areas and all roads were paved at the end of the Project.

The Pump House portion consisted of Building a 16’ x 26’ Wood Framed Building with Vinyl Siding, Wood Trusses and a Standing Seam Metal Roof from foundation to finish. The existing 10 HP Well Pump and piping were replaced and a stilling well and well level transducer were installed. Inside of the pump station there are two 2050 Gallon Storage Tanks that are filled by the Well. The Well water is treated by two greensand filters and an arsenic removal filter prior to filling the storage tanks. Two 3 HP 30 GPM Booster Pumps and all SCH 80 PVC Piping and Valves were installed for all water service to the distribution piping outlet connection. The booster pumps and instrumentation are automatically controlled by the RE Prescott Control Panel with user adjustable level, flow and pressure settings and multiple user configurable alarms with time delays and Web Based Portal alarm call out ability. The interior is automatically temperature controlled by a new HVAC System. The old existing Pump House was demolished and removed and the surrounding area was restored at the end of the Project.

This is another example of HAWSCO’s ability to safely deliver a top notch, turn key Project from start to finish on time and on budget.

Rockingham County Complex – Brentwood, NH
Greensand Filtration System Design/Build

HAWSCO was contracted by the Rockingham County Complex in Brentwood, NH to complete a full design/build upgrade of its Greensand Filtration System. The water system serves a large and diverse group of buildings including general administrative offices, a nursing home, an assisted living facility, a correctional facility, engineering and maintenance buildings, and the offices of various elected officials. The project also included integrating service to the newly constructed Sheriff’s Building.

To maintain uninterrupted operation during construction, HAWSCO first installed a temporary filtration system. The existing filtration system—consisting of two 8-foot diameter greensand filter vessels, associated valves, controllers, and piping—was fully removed.

HAWSCO then furnished and installed two new 8-foot diameter pressure filter vessels, each capable of handling 120 GPM. Each vessel was equipped with inlet distributors, backwash collectors, air wash and underdrain distribution systems, and new media including gravel, anthracite, and greensand. All new Schedule 80 PVC piping was installed with resilient-seated butterfly valves and electric actuators for full control integration. A high-capacity blower and stainless steel air scour piping were installed to improve backwashing efficiency.

Instrumentation and control upgrades included new magnetic flowmeters, pressure transducers, and other control devices, all integrated with the main control panel. The project also replaced and upgraded all chemical feed systems, including new peristaltic pump skids with calibration columns, day tanks, injection quills, and safety accessories for both KMnO₄ and sodium hypochlorite.

The system’s SCADA platform was upgraded to allow for full automation and communication between the filtration system and central plant control. Filters now regenerate based on differential pressure or flow totalization, whichever occurs first. Since commissioning, the upgraded system has quadrupled filter runtime between regenerations while using only one-third of the water previously required—resulting in significant water and energy savings.

INNOVATION: NEW APP STREAMLINES WATER OPERATIONS

Mon, 06 Mar 2017 19:07:00 GMT

Clean drinking water is often something we take for granted. When we fill our coffee makers in the morning, when we ask for a water at the local eatery, or when we rinse after brushing our teeth, we trust that the water we consume is safe. This security doesn’t come easily. Behind the scenes service companies such as Hampstead Area Water Services Co (HAWSCO) are continuously monitoring water supplies.Certified water operators are required by the New Hampshire Department of Environmental Services to provide routine monitoring, testing, and sampling of well water supplies for communities and organizations to name a few. Add up a number of businesses, homes, developments, and organizations that use well water and it’s easy to see that this is a large task spread out over a large area.THE PROBLEM:Routine maintenance inspections were reported on paper for each water station, meter readings calculated manually by the operator who relied on previous written reports data.Reports were then brought back to the office, manually entered into an excel file, and brought back to the water station for the next succession of reporting.This redundant process was not only cumbersome but lacked any user validation or timeliness.THE GOAL:Develop a custom app that would automate calculations, populate real-time data to a central database, and provide administrators instant access to the reports.THE SOLUTION:The HAWSCO team utilized a new web-based coding tool known as Appsheet to develop a custom app that works on the water operators' iPads. The app integrates with online databases to produce real-time data for all of the water systems. In addition, the app sends reports by email to Charlie when they are submitted by the water operators performing the maintenance inspections. In addition, the sharing capabilities of the app allows other office personnel to access the database for additional billing and reporting to NHDES.ICING ON THE CAKE:HAWSCO started using the app and realized that the Ipads combined with the new app could also be used to instantly submit photos of potential issues to the manager allowing for pre-emptive maintenance versus reactive maintenance.WHAT WERE SOME OF THE CHALLENGES TO IMPLEMENTING THIS NEW SYSTEM?As with implementing most process changes involving technology there is always a learning curve… Both with the users, the creators of the system, and the hardware running the system. We’ve experienced a few bugs and other hiccups, but overall the application has provided numerous benefits.HOW HAS THE APP CHANGED THE WAY YOU DO BUSINESS?To give some background, the way we used to perform station maintenance reports at our water system facilities included handwriting onto paper reports that were left in binders at the stations. These binders were subject to moisture, chemicals, etc. and did not fare well. We then had to periodically bring the paperwork to the office to be scanned, entered, etc. and then brought back to the facility binders. With the new system, our water operators utilize iPads to type in their reports which then automatically update to the office in a spreadsheet and also in graphical form that all employees can easily access anywhere with an internet connection.WHERE DO YOU SEE THIS APP GOING NEXT?One of the avenues we plan to utilize this system is within our contracted services division, HAWSCO. We plan on providing customer portals on the www.nhwaterservices.com website where the customers can log in and have up to date reports regarding their facilities. We also anticipate generating custom reports in the future.WHAT WERE SOME UNEXPECTED BENEFITS TO USING THIS NEW APP?One of the greatest benefits has been the ability to deploy updated maintenance sheets real time rather than printing paper copies and having the operators bring them to the individual facilities. We’ve also found unique ways to incorporate new reports that we previously would hand write as well.For more information on water operations in NH, certified water operators in NH, or the app utilized by Hampstead Area Water Services Co. to report on community water systems data, visit www.nhwaterservices.com, call 603-362-5333, or email us at operations@hampsteadwater.com.

What's My Risk of Running Out of Water in a Drought?

Thu, 29 Sep 2016 15:49:00 GMT

The current drought situation in southern New Hampshire has brought on a wave of questions regarding appropriate water use, consumption, and supply. Here at HAWSCO, we're often asked the question, "How's my water supply looking?" Several inquiries have also been submitted asking "why?" or "why hasn't?" a water ban has been issued. In this post, we'll lay out some of the underlying factors that hopefully provide answers to these types of questions. We'll do our best to keep things simple, but if you have specific questions, don't hesitate to contact us.

First things first, let's review the types of water systems:If you live in New Hampshire, you're most likely on your own private well, a community water system, or a municipal water system which may operate on wells or draw from a water reservoir such as Lake Massabesic for the City of Manchester. These systems all have differences even when they are of the same type.One big misconceptionA common misconception is that we all draw water from the same giant underground pool of water. The reality is that underground water fills pores and cracks in, around, and between sand, silt, gravel, and bedrock. Your water supply might come from one deep crack in the bedrock while your neighbor's from a shallow gathering of water-soaked sand and gravel. You could run your well dry and your neighbor's well might not even flinch because their well draws from different pores and cracks.

The diagram below explains how the various water systems work and where the water comes from:Diagram depicting various types of water systems and the underground sources of water(click diagram to enlarge).Private wellsA private well, much like the artesian/drilled one that my family relies on, only services my house and therefore is my responsibility for maintenance and repairs. My well was drilled down 240 ft into a water-bearing bedrock fracture yielding 60 gallons-per-minute of water.Click diagram to enlargeMy well pump is located 140 ft down into the well. The static water level (water table) was initially recorded at 10 ft below ground surface, meaning I should have 130 ft of "available" water draw-down before the well runs dry and needs to recover. At 60 gallons-per-minute though, I might expect the well to recover rather quickly.When my house was built, long before my family moved in, the well driller determined these specifics. The well was drilled to 240 ft because there is likely a water-bearing fracture in the bedrock located near that distance below ground. In NH, most wells installed after 1984 have these details recorded at: http://www2.des.state.nh.us/DESOnestop/BasicSearch.aspxMy neighbors on each side have wells spanning 200 ft to 400 ft with between 2 and 8 gallons-per-minute of supply. They need to be a little more cautious drawing water down too quickly since their water-bearing fractures do not yield much water.Not all private wells are artesian or drilled. Some are dug wells and some are sand & gravel wells. A dug well might be more prone to dry out during a drought mainly because they are so shallow. A dug well at 15 feet below ground only has a few feet of available water draw-down before it reaches the pump level.A sand & gravel well located in a stratified drift aquifer might be just as shallow, but has such a strong yield (gallons-per-minute of water supply) that it is constantly replenishing despite usage.Stratified Drift Aquifers Southern NHSource: http://granitviewii.unh.edu/(click map to enlarge)While homeowners with private wells typically have the freedom to use or conserve water at their own discretion, it is wise to follow the New Hampshire Department of Environmental Services' recommendations especially in times of drought. It is also important to recognize that the town can still enforce watering bans on you even if you own a private well. Community/Association Water SystemsIf you live in a condo or homeowner's association outside of the main metro areas, it is likely that your water comes from a community water system. While they are all different, these systems usually consist of one or several wells connected to a water storage tank and pump house (360 photo shown above). The pump house might contain various meters, booster pumps, filters, and treatments to provide safe drinking water to the entire association or community. These water systems have state requirements that Certified Water Operators monitor the water supply 24/7.

You can learn more about this at HAWSCO's website www.nhwaterservices.com . If you are concerned about drought conditions affecting your community water system, it might ease your worries to know that certified water operators are analyzing usage data with historical data and forecasts to determine if water supply is a concern.Public Water UtilityA public water utility system sometimes referred to as "town or municipal water" is typically drawn from a water reservoir, but might also contain wells. The water is treated at a much larger facility than a community water system pump station. While the water utility will monitor reservoir levels, storage tanks, and reservoir sources to determine if a water restriction is needed the decision might be influenced by government officials and bureaus who regulate the water utility. So, to answer the big question, "What's My Risk of Running Out of Water in a Drought?"It really depends on all of the above factors (and a few more that would make this post longer than it already is). Hopefully, you can use the information in this post and the details of your specific well provided at: http://www2.des.state.nh.us/DESOnestop/BasicSearch.aspx to determine if you should be concerned during a prolonged extreme drought.In summary, if your neighbor's well run's dry, or if they are excessively watering their lawn, consider the differences they might have in their well or water system before making judgments or accusing them of using up all of the water in the neighborhood. With that in mind, let's not forget that water conservation/waste in general, might have an effect on our children's future.
