Waukewan stormwater treatment practices installed

Join us on Wednesday, August 23rd, 6pm for a tour of the recently completed stormwater treatment practices installed at the Waukewan St. bathhouse in Meredith.

completed rain gardenThe Waukewan bathhouse site is one of the top 6 sites out of more than 60 sites identified in the updated Waukewan and Winona Watershed Restoration plan completed in September 2016 as contributing sediment and other pollutants to the lake.

Lake Waukewan is the town of Meredith’s drinking water supply source and is currently listed on the State of NH’s 303(d) list of impaired waters.  Issues associated with the site include surface and road shoulder erosion, bare soil in the parking area, and a winter sand-snow dump area.  Stormwater improvements made include re-grading and paving the parking area, re-directing stormwater runoff to a rain garden bio-retention basin, and retrofitting the existing catch basin to a deep sump catch basin.

The tour will be held at the bathhouse parking lot located at 72 Waukewan St., Meredith.  Lakes Region Public Access will film the program for viewing on our website.  A rain date has been tentatively scheduled for August 29th, 6pm.  For more information about the program, please contact the Lake Winnipesaukee Association at 603-581-6632.

The project was partially funded by a Local Source Water Protection grant through the New Hampshire Department of Environmental Services.

The Lake Winnipesaukee Association is grateful to the town of Meredith for providing in kind services, the Windy Waters Conservancy for their donation, and the volunteers who helped make this project possible.

Septic Sense

Effluent from failing septic systems is a major water quality concern in the Lake Winnipesaukee watershed, as the majority of properties around Lake Winnipesaukee rely on onsite wastewater disposal systems (septic systems).  Compounding the issue is the fact that many properties are seasonal, second homes or rental properties.  Many property owners may not know that they have a septic system, or where it’s located or when it was installed.

To help people better understand the functioning of septic systems and how to care and maintain this critical component of their home, LWA has sponsored several Septic Sense Seminars around the Winnipesaukee watershed over the past few years.

Proper Use and Maintenance of Septic Systems

Septic SystemEverything that goes down the drain, toilet, dishwasher, bathtub, and/or washing machine goes to some type of waste water disposal system; usually  either a private septic system or a municipal sewer system.

If a home is on a private system, that system needs to be maintained in order to function properly.  Why?

The septic system is a two-part sewage treatment and disposal system buried in the ground, composed of a septic tank and a leaching system.  The sewage generally flows by gravity; first into the septic tank where the larger particles are removed and some decomposition takes place and then into the leaching system where it soaks into the ground.

The effluent that enters the leach field contains bacteria (E. coli), nitrates, phosphorus, and other chemicals;  remember – whatever you put down your drain or toilet ends up in your septic system!

The leachate or effluent from your septic system eventually filters through the soil and becomes groundwater.  If your system was located and installed properly and maintained, this arrangement works to naturally filter out the pollutants.  However, inadequately functioning and/or failing septic systems contribute to groundwater contamination.  Wastewater from septic systems may include many types of contaminants, such as nitrates, harmful bacteria and viruses.

Protect Your Septic System

1. Regularly inspect your system and pump your tank as necessary.

2. Don’t dispose of grease, coffee grounds, diapers, cat litter, latex paint, feminine hygiene products, household hazardous wastes, etc. in sinks or toilets.  These items can clog the distribution lines or impair the function of the tank.

3. Minimize or eliminate use of sink disposal units which place an added burden on your system.

4. Care for your leach field (drainfield).  Avoid driving or parking vehicles on it.  Plant only grass over or near the leach field to avoid damage by roots.

5. Avoid use of water softeners; the salts which discharge during backwash into a septic system can crystallize and clog the distribution lines.
