Residential Swimming Pool and Hot Tub Maintenance

Stormwater Pollution Prevention Manual King County Stormwater Services 132 July 2021 R-7: Residential Swimming Pool and Hot Tub Maintenance Improper drainage or discharge of water from swimming pools, hot tubs, or spas to storm drains or ditches during maintenance activities can lead to pollution of streams, rivers, and lakes. Chemicals used in pool, spa, and hot tub maintenance can contaminate stormwater and surface water if they are not stored, used, and disposed of correctly. Potential pollutants can include but are not limited to fecal coliform bacteria, nutrients, oxygen demanding substances, pH, and sediment. Best Management Practices (BMPs) are required by King County Water Quality Code (KCC 9.12). If the BMPs included here are not enough to prevent contamination of stormwater, you will be required to take additional measures. Required Operational BMPs • Clean the pool, spa, hot tub, or fountain regularly. • Maintain proper chlorine levels, water filtration, and circulation, which will limit the need to drain the facility. • Manage pH and water hardness to reduce copper pipe corrosion that can stain the facility and pollute receiving waters. • Before using copper algaecides, try less toxic alternatives. Only use copper algaecides if the other alternatives do not work. Ask a pool/spa/hot tub/fountain maintenance service or store for help resolving persistent algae problems without using copper algaecides. • Develop and regularly update a facility maintenance plan that follows all discharge requirements. • Dispose of unwanted chemicals properly. Many of them are hazardous wastes when discarded. • Store pool chemicals under cover and in enclosed containers. Required Water Disposal BMPs If the pool or spa does not have a permanent drain connection, then water must be pumped or drained to the sanitary sewer or meet the following BMPs. • Discharging pool and spa water if sanitary sewer is not available: o Non-saltwater and saltwater pool and spa water  Have it hauled off-site for disposal at an approved location; or  Infiltrate to ground if all 9 conditions below are met. Saltwater pool and spa water must not be allowed to flow off-site, nor may it enter stormwater drainage systems or surface waters. Saltwater discharges can elevate salt concentrations in your soil and damage vegetation. o Non-saltwater pools and spas only  Drain to the stormwater drainage system if all 9 conditions listed below are met Stormwater Pollution Prevention Manual King County Stormwater Services 133 July 2021 • Conditions for draining to ground (non-saltwater and saltwater pools and spas) or to a stormwater drainage system (non-saltwater pools and spas only): 1. No copper-based algaecides were used; 2. The water must be tested to determine chlorine levels and pH; 3. The water is dechlorinated to 0.10 ppm Chlorine or less, using neutralizing chemicals or by letting the pool or spa “sit” long enough to reduce the chlorine level to the allowable limit. The pool or spa must not be used during this period; 4. The pH is neutral (6-8); 5. Free of any coloration, dirt, suds, or algae; 6. Free of any filter media; 7. Free of acid cleaning wastes; 8. Released at a rate that does not cause erosion either onsite or in the drainage system; and 9. At ambient temperature. • Saltwater pool and spa water must not be discharged to the stormwater drainage system. Either infiltrate to ground if all 9 conditions above are met or hire a professional pool-draining service to collect all water for off-site disposal at an approved location. • Diatomaceous earth (commonly used as a filtering agent) and water from back flushing filter systems cannot be discharged to surface waters, storm drainage systems, septic systems, or the ground. Dispose of diatomaceous earth filter material as solid waste. • Do not discharge pool or spa water to a septic system, as it is prohibited and may cause the system to fail. • The discharge of pool and spa filter backwash or cleaning water to the ground, surface waters or the storm drainage system is not allowed. Tips • Hire a professional maintenance company to service your pool, hot tub, or spa.

EJ League of Rhode Island, Urban Ponds and Stormwater

Summary: Urban ponds and stormwater, environmental justice, pollution in local pond, greening neighborhoods, managing stormwater in urban areas to handle pollution, heat islands, recreational opportunity access, green spaces

The EJ League, Urban Pond Procession, and Groundwork Providence are working together on a new campaign to address stormwater pollution in Mashapaug Pond, Providence’s only remaining natural pond, located in South Providence.
See below for all the great successes we’ve already had in Reservoir Triangle around the pond! Addressing stormwater pollution has a ton of positive impacts you might not even be aware of — things like:
beautifying and adding green space to urban neighborhoods
improving air quality with more trees and plants
reducing flooding on our streets
creating jobs and training opportunities for Providence residents
helping our neighborhoods be more resilient in the face of climate change impacts like heat waves, storms, and major flooding events
improving the quality of Rhode Island’s water bodies and beaches — from our urban ponds and rivers to Narraganset Bay — they’re all connected!
Solving our stormwater problem is central to achieving environmental justice in Providence and Rhode Island’s other urban centers. Our urban communities have higher poverty and unemployment rates, its where the majority of people of color in the state live, and these are the same places with poorer air and water quality and less access to good things like green space, recreational opportunities, and the beauty of the natural environment. Cleaner water means more recreational opportunities like fishing and boating can happen right in our cities and we’ll be safer when we go to beaches on the coast. Protecting our waterways, adding more green space, and improving the public spaces we already have means we’ll benefit by being more connected to the natural environment too. Investing in
green infrastructure
means more jobs can be created for residents in Providence and other cities to install and maintain rain gardens and permeable pavement, de-pave driveways and right-of-ways, cut curbs and plant trees.
Check out our resident handbook on stormwater and green infrastructure
below, created specifically for Reservoir Triangle, but can definitely be used for other neighborhoods across the state!

September 15th, 2012 – Kick-Off – Mashapaug Pond Party:
We want to make sure people see Mashapaug Pond as a
real asset and natural resource in our city
. Duck Truck Tours are a good first step! We took about 75 people out on the water at our kick-off event in September and had a great time with food, music, and games for kids.

October 20th, 2012 – Stormwater Walk
led by George Harvey, Landscape Designer and project partner from
Groundwork Providence
: 20 people from the neighborhood and allies from partner organizations participated in a walk around Mashapaug Pond, focusing mostly on JT Owens ballfield and the Huntington Industrial Park.
George talked with us about various ways stormwater could be better managed to prevent runoff from the fields and businesses
there including:
raising grated storm drains located near baseball fields to slow down water rushing into pond
planting native plants to prevent soil erosion and slow water down, help it be absorbed
identifying specific pollution sources and stopping them at the source (see photo below)
raising the top of a building’s downspout just a couple inches so that rainwater can collect on the roof of the building and naturally evaporate rather then run down the downspout into the street
directing downspouts into plants, grass, or other vegetated areas
Check out this presentation created by Ana Mendiburu, a Reservoir Triangle resident, that summarizes what we learned on the stormwater walk:
Stormwater Walk Overview
(pdf)
Starting in November, members of our team reached out to businesses in the industrial park, many of which have been very receptive to our ideas about better managing stormwater runoff from their properties. We’re looking forward to working with them to improve their stormwater management practices, including a springtime tree planting among other projects. Stay tuned for more updates on this!

January 19th, 2013 – Residential Stormwater Workshop:
Neighborhood residents, City staff from the Parks Department and Office of Sustainability, among others, participated in a workshop to look at how individual residents could improve stormwater management at their homes and in the neighborhood as a whole.
Residents will begin meeting together to plan out springtime activities and outreach in the neighborhood to get more of their neighbors involved.
George Harvey co-led this workshop and prepared incredibly useful documents (see below) to help residents see tangible ways they could
prevent stormwater runoff from their homes, roofs, and lawns
. While a significant portion of the Reservoir Triangle neighborhood’s stormwater flows into the pond, especially from the homes right on the edge of the pond, much of the neighborhood’s stormwater goes into Combined Sewers (pipes where wastewater and stormwater combine) that are directed to Fields Point, the wastewater treatment facility off Allens Avenue. Ultimately all this treated water goes into Narragansett Bay. This still means stormwater can overburden the system and cost taxpayers and the City money — so figuring out ways to absorb more stormwater in the neighborhood will help a great deal.
Here are some photos of typical downspouts in Providence
– almost always letting out water from the roof onto concrete or some other non-absorbing material. Changing this can be easy though. We’ll be piloting some ideas in Reservoir Triangle this spring!

Here are some of the ways residents can help absorb more water coming off their roofs, lawns, and driveways.

May 4th, 2013 – De-paving Demonstration Project at 46 Crescent St.:
Reservoir Triangle resident, Laura Maxwell, volunteered her driveway to our project, allowing the Groundwork Providence green job training program to remove a layer of asphalt and about 6 inches of concrete from her driveway, replacing it with geoblock material and grass that will still allow her to drive across it to get to her garage but will absorb rain water coming off the roof of her house — helping reduce the stormwater load on Mashapaug Pond. Thanks Laura!
Check out these photos of the process:

The end result: A grassy area that can absorb roof runoff and stormwater!
October 2013 – Right-of-Way Depaving and Planting:
Nellie Richardson and her family gave the EJ League the go-ahead to cut the concrete in front of their home on Algonquin St and create a planted buffer in its place. This was done with permission from the Providence Department of Public Works, with some materials donated by the Parks Department. The work was conducted by Groundwork Providence’s job training crew. Thanks everyone!
Check out the before and after photos:
The planted buffer captures roof runoff, filters pollutants, and prevents flooding on this street corner!
The EJ League is also working with businesses on the other side of Mashapaug Pond in the Huntington Business Park to implement stormwater solutions.
Ximedica, RI PBS, and Brown University’s Library Collections Annex all participated in a spring tree planting in 2013:
And we’ll be continuing this outreach in 2014!
The RI Department of Environmental Management, in collaboration with our project, was awarded $50,000 through a legal settlement against Southern Union (an oil/gas company that was found guilty of illegally storing mercury in an unlocked shack in Pawtucket). This money will go directly to support green infrastructure projects in the Huntington Business Park — and give Groundwork Providence’s job training graduates — GroundCorp — an opportunity for paid, on-the-job professional development. More details to come on this exciting development!

The main goals of our Mashapaug stormwater project are to:
Develop a core group of resident leaders to design and lead this project
Educate and engage residents and schoolchildren in the Reservoir Triangle neighborhood on ways they can contribute to the pond’s restoration through outreach, workshops, as well as hands-on trainings in basic stormwater management techniques led by
Groundwork Providence
Engage businesses in the Huntington Industrial Park located between Niantic Avenue and the pond, get commitments from them to reduce runoff from the business’s properties, and help them achieve these goals
Explore the potential to create jobs for Providence residents in the area of stormwater management and adding more green space to our city through innovative funding strategies
Urban stormwater runoff is a major source of pollution for all of our city’s waterways, including Mashapaug Pond, which creates unsafe conditions for people and ecosystems. Too much phosphorus from pet waste, fertilizers from people’s lawns, oil from the road, road salt, etc. wash into our waterways when it rains and contaminate them. In Mashapaug Pond, this process helps toxic bacterias develop that are a hazard to people and pets and reduce oxygen levels in the water, making it difficult for healthy plant and animal life to survive.
The solutions to this problem lie in eliminating these pollutants from runoff in the first place (picking up pet waste, not feeding geese or other birds, not using lawn fertilizers, ensuring motor oil is securely disposed of, etc) and increasing the amount of absorptive surfaces in our city — meaning increasing the amount of grass, plants, and trees, and reducing the amount of asphalt, concrete, and other surfaces that don’t absorb rain water.
Check out these
maps of Reservoir Triangle
created by George Harvey/Groundwork Providence that show
how much of the land us taken up by impervious surface
(meaning surfaces that don’t absorb water). Unfortunately this is all-too common all across Providence and is the biggest reason for polluted water quality in our city and state:

History of the UPP:
Artist Holly Ewald started the Mashapaug Pond Procession as a culminating public event in June 2008 after a several-month residency in local schools and community centers educating young people about the pond and creating silkscreen posters and fish costumes. The posters were then the inspiration for 4 new more pictoral signs with text translated in 3 languages warning pond visitors of the health hazards of the pond site. Eight new signs fabricated by the Department of Transportation are permanently in place around the pond.
The new signs placed around Mashapaug Pond.

2023 Fact sheet for Non-vegetated Filtration Swale Effectiveness Study

Summary: Fact sheet, non-vegetated filter strip, eastern washington, study results non-vegetated filtration strip, BMP efficacy study results, West Richland study fact sheet

NON-VEGETATED FILTRATION SWALE EFFECTIVENESS STUDY
Non-Vegetated Filtration Swale Effectiveness Study | Fact Sheet
Study Goal and Background
The goal of this study was to evaluate the
effectiveness of a non-vegetated filtration swale
BMP. Effectiveness was based upon whether the
BMP could provide basic treatment (80% reduction
of total suspended solids) in accordance with
Ecology treatment performance goals.
Constructing a non-vegetated filtration swale is
highly desirable for locations with hot and dry
summers or in areas where dry periods cause
grass to become dormant or where supplemental
water is needed to establish vegetation. A non-
vegetated BMP will benefit multiple Washington
State Permittees by providing a BMP option that
does not require irrigation. This fact sheet is a
summary of the information found in the Non-
Vegetated Filtration Swale Effectiveness Study
Technical Evaluation Report.
Study Description
The study goal was accomplished through controlled tests conducted at a test site in West
Richland. Four swale design alternatives (alternatives) were tested in 200-foot-long swales at
the site followed by one final swale design alternative (final alternative) as shown in Figure 1.
The final alternative was selected based on the treatment performance of the four alternatives.
A cross-section of the final alternative swale design is shown in Figure 2.
Figure 2: Final Swale Alternative Cross Section
Figure 1: TEST SWALE AND SAMPLE LOCATIONS
NON-VEGETATED FILTRATION SWALE EFFECTIVENESS STUDY
Non-Vegetated Filtration Swale Effectiveness Study | Fact Sheet
Treatment performance was measured from
samples collected from each alternative, which
were analyzed for total suspended solids (TSS). An
influent distribution system mixed and pumped
synthetic stormwater to the swale at the design
flow rate to simulate a storm event (as shown in
Figure 3).
As the synthetic stormwater flowed through the
swale, grab samples (shown in Figure 4) were
collected in eight sample locations that were
spaced at 25-foot increments along the swale.
After each simulated storm event, an amount of
TSS equivalent to one year of loading was
distributed to the swale to stress-test the swale
and determine when the swale would require
maintenance.
The travel time for stormwater to flow through the
swale was recorded at each sample location. The
measured travel time was then used to estimate the velocity of flow through the treatment
layer. This information was used to inform the velocity limits for the swale design guidance.
FIGURE 3: INFLUENT DISTRIBUTION SYSTEM AT TEST SWALE
Figure 4: GRAB SAMPLE FROM TEST SWALE
NON-VEGETATED FILTRATION SWALE EFFECTIVENESS STUDY
Non-Vegetated Filtration Swale Effectiveness Study | Fact Sheet
Study Location
The test site location was south of the City of West Richland Public Works Building and adjacent
to a gravel parking lot (as seen in Figure 5). An existing 430-foot-long swale at the test site was
retrofitted into the two 200-foot-long test swales. The controlled tests were conducted during
the dry season; therefore, no runoff from the gravel parking lot contributed to the test swales.
Results
The initial percent removals for the final alternative indicated that 84.5–87.8% removal of TSS
was achieved for the first simulated year, at the sample location at 200 feet from the start of
the swale. However, percent removal decreased for the following two simulated years, which
was likely due to modifications to the swale needed near the last sample port, due to observed
erosion from a grade break immediately downstream of the swale. As a result, the samples
collected at the last sample port (200 feet) were discarded and statistical trendline analysis
was used to determine how the swale would have performed if the swale modifications had
not occurred. This analysis is shown in Table 1 and indicates that the swale met performance
goals for the first two years. Since the treatment performance dropped below 80% for the third
year, it is likely that maintenance would need to be performed sometime around the third year
to restore treatment performance. Further testing needs to be done to confirm the
maintenance procedures and schedule.

1. Results shown are concentrations developed using trendlines.
The percent removal results in Table 1 were compared to the TAPE treatment performance
goals for TSS using the bootstrap statistical analysis to predict the treatment performance of
the swale. Years 1 and 2 represent the performance of the swale before maintenance is needed.
However, only two data points were available, causing the result of the bootstrap analysis to
be equivalent to the lower of the two removal efficiencies. The evaluation of removal
efficiencies calculated for years 1–3 added one data point and indicated the swale would meet
the TAPE treatment performance goal for all three simulated years.
The measured travel time for flow to travel through the
swale was 50 minutes, from which a design velocity of
0.066 ft/sec was calculated. It is anticipated that
treatment will be provided by a swale 200 feet long if the
velocity and residence time are less than or equal to the
values measured during the study.
Future Action Recommendations
Submit the swale for Conditional Level Use
Designation, so the performance of the swale can be
further evaluated in the field for actual storm events.
Perform additional field testing to understand
effective maintenance activities to restore the swale
treatment performance every two to three years and
the frequency at which more minor action items
such as removal of sediment and debris from inlets,
weed control, etc., should be performed.
Perform additional field testing to understand the impact that a catch basin or forebay
at the inlet would have on treatment performance and maintenance cycle of the swale.

Stormwater Pollution Prevention for PRESSURE WASHING Keep our communities, creeks, lakes, and Puget Sound healthy. Special Considerations for Buildings: PCBs • Buildings built or renovated from about 1950 to 1979 had widespread use of PCBs (polychlorinated biphenyls). • PCBs may be present in caulking, grout, joint materials, paints, sealants, lubricants, roofing, metal coatings, and light ballasts. • PCBs are toxic and cancercausing chemicals. Wash Water Disposal • Wash water that contains solid waste and petroleum products must be filtered prior to disposal. Hazardous Waste Disposal • Pressure washing can create hazardous waste that needs special disposal, including: » Dirty absorbent materials that may contain PCBs. » Rags or absorbent pads with gasoline, oils, grease, thinner, solvent, or organic chemicals. • Dispose of hazardous waste properly. » Option 1: Use a licensed waste hauler. » Option 2: Bring small quantities of accepted waste to a hazardous waste drop-off location. • Keep records of your hazardous waste disposal: who hauled it, how much was hauled, and when it was hauled. To request an ADA accommodation, contact Ecology by phone at 360-407-6600 or email at [email protected], or visit ecology.wa.gov/accessibility. For Relay Service or TTY call 711 or 877-833-6341. Type of Wash Water Dispose to Sanitary Sewer Dispose to Ground Dispose to Storm Drain or Natural Water Body Plain water + filtered Soapy water + filtered Dirty/turbid water Oily water + oil-absorbing filter Dirty or soapy water with no filtration PCBs In Buildings tinyurl.com/tmbth5wn * * * *check with your local jurisdiction Find a Hazardous Waste Service Provider Find a Hazardous Waste Disposal Site tinyurl.com/y64pt48r tinyurl.com/46nczhbk Setup • Identify where wash water will flow and temporarily cover storm drains. • Use a containment system to capture wash water. » For ground surfaces, use a pressure washer with a built-in water reclaimation system. » For equipment and vehicles, line the area with a ground tarp and surround it with a temporary berm. • Equipment needed for portable wash water containment system: Pressure Washing Best Practices for Pollution Prevention Capture the Wash Water • While washing, move or adjust the containment system to capture and contain the wash water. Treat the Wastewater • Use filter fabric to filter the water. • Solid pieces of waste go into the garbage. General Best Practices for Pressure Washing • Sweep work areas to cleanup. • Cover or block nearby storm drains. • Do NOT direct or pour wash water into a storm drain. • DO manage wash water by one of these options: 1. Direct into a landscaped area to soak into the ground. 2. Discharge to the sanitary sewer (toilet or indoor sink) is okay if the water has only small amounts of grit or oil. The Problem • Wastewater from washing practices can contain toxic pollutants. • Pressure washing can release pollutants from surfaces due to the force of the water. • When not cleaned up properly, waste from washing can pollute stormwater runoff. • Storm drains flow to the nearest creek, lake, wetland, or Puget Sound. Only Rain Down the Drain • Regulations and laws about pressure washing can vary by location, and some jurisdictions strictly regulate pressure washing. • But they all have one thing in common: ONLY RAIN DOWN THE DRAIN. • Do NOT use soap or chemicals. • Wash water that contains soap (including biodegradable), chemicals, soil, or is untreated should NOT be dumped – these are pollutants and can kill fish. Sweep and use dry cleanup methods. Do NOT hose off the ground.

Excavación y nivelación • Al hacer trabajos de excavación o nivelación, no arrastre lodo y tierra a la calle, las aceras y las canaletas con vehículos y equipos. • Proteja los drenajes pluviales que estén en los lugares de trabajo, o cerca de ellos, con bolsas filtrantes o cordones absorbentes. • Use rollos de fibra, tapices vegetales, cortinas de sedimentación y otros materiales para control de la erosión para estabilizar la tierra después de nivelar o excavar. • Dirija las aguas lodosas hacia zonas con jardines, para que se absorban en el suelo. Mejores prácticas para prevenir la contaminación en la jardinería comercial Limpieza • Sople las hojas secas y el césped cortado hacia la tierra para usar como mantillo. No las sople hacia las calles, ni a las entradas del drenaje pluvial. • Enjuague los recipientes vacíos y deseche el agua de enjuague en áreas con jardines, o reutilícela al preparar otra mezcla para aerosol de la misma sustancia química. • Barra los materiales secos. • Use agua para limpiar SOLAMENTE cuando se drenará a áreas con jardines. • NO use jabón o sustancias químicas en el agua para lavar y NO la dirija hacia las calles, las canaletas o las entradas de drenaje pluvial. Riego • Use sistemas de riego programables para evitar el riego excesivo, que puede provocar erosión del suelo. Evite que los escurrimientos lleguen a aguas superficiales o áreas pavimentadas. Capacitación de trabajadores • Capacite cada año a sus trabajadores sobre el uso de sustancias químicas peligrosas, cómo evitar derrames y cómo limpiarlos. • Mantenga un registro de los cursos de capacitación y los empleados que asistieron. • Siga las directrices de un plan integrado de control de plagas, ya sea de usted o de su jurisdicción local. • Conozca sus hierbas nocivas y las leyes locales referentes a hierbas nocivas. • Use fertilizante orgánico siempre que sea posible. • Esparza solamente la cantidad necesaria (y no más), siga las instrucciones de la etiqueta. • Mantenga cerrada la tapa cuando no lo esté usando, asegúrese de que la etiqueta sea legible y correcta. • Guarde las sustancias químicas en interiores o bajo techo y en una tarima de contención secundaria, para atrapar las fugas y derrames. • Nunca aplique sustancias químicas cuando esté lloviendo o a punto de llover.
