1.1 Preamble. The Secretary of Delaware Health and Social Services adopts these Regulations pursuant to the authority vested in the Secretary by 16 Del.C. §122. These Regulations establish standards for the sanitary operation of public pools. For the purpose of these Regulations, the term “public pool” as defined in 16 Del.C. §122(1) and (3) (d) and (j). These Regulations provide a system of permitting and inspection of public pools and procedures for enforcement.
1.2 Purpose. To provide minimum standards for design, construction, maintenance and operation of public pools in the State of Delaware, and to assure a clean, healthful, and safe environment for all bathers using these pools. These Regulations in no way preclude a facility from establishing additional rules and operating procedures as long as they do not contradict those established herein.
1.3 Severability. In the event any particular clause or section of these Regulations should be declared invalid or unconstitutional by any court of competent jurisdiction, the remaining portions shall remain in full force and effect.
1.5.1 A licensee may seek a variance from these Regulations by making a request for variance to the Division. The Division may grant a variance by modifying or waiving the requirements of these Regulations if in the opinion of the Division a health hazard or nuisance will not result from the variance.
“Approved” means acceptable to the Division, unless stated otherwise, based on its determination as to conformance with appropriate standards and good public health practices.
“Aquatic Facility” means a physical place that contains one or more aquatic venues and support infrastructure.
“Aquatic Facility or Aquatic Venue Enclosure” means an uninterrupted barrier surrounding and securing an aquatic facility or aquatic venue.
“Aquatic Feature” means an individual component within an aquatic venue. Examples include slides, structures designed to be climbed or walked across, and structures that create falling or shooting water.
“Aquatic Venue” means an artificially constructed structure or modified natural structure where the general public is exposed to water intended for recreational or therapeutic purpose. Such structures do not necessarily contain standing water, so water exposure may occur via contact, ingestion, or aerosolization. Examples include swimming pools, wave pools, lazy rivers, surf pools, spas (including spa pools and hot tubs), therapy pools, waterslide landing pools, spray pads, and other interactive water venues.
“Increased Risk Aquatic Venue” means an aquatic venue which due to its intrinsic characteristics and intended users has a greater likelihood of affecting the of the bathers of that venue by being at increased risk for microbial contamination (e.g., by children less than 5 years old) or being used by people that may be more susceptible to infection (e.g., therapy patients with open wounds). Examples of increased-risk aquatic venues include spray pads, wading pools and other aquatic venues designed for children less than five years old as well as therapy pools.
“Lazy River” means a channeled flow of water of near−constant depth in which the water is moved by pumps or other means of propulsion to provide a river−like flow that transports bathers over a defined path. A lazy river may include play features and devices. A lazy river may also be referred to as a tubing pool, leisure river, leisure pool or a current channel.
“Spa” means a structure intended for either warm or cold water where prolonged exposure is not intended. Spa structures are intended to be used for bathing or other recreational uses and are not usually drained and refilled after each use.

“Attendant on Duty” means an attendant who is either at poolside or in the pool (special situations), visually guarding the life of the bathers. An attendant on duty shall not be assigned other duties that will distract his/her attention from proper observation of the bathers, or prevent the rendering of immediate assistance to someone in distress. In facilities with a spa pool(s) only it means an attendant who is on the premises and can be easily located and summoned to render assistance to someone in distress. If the attendant is not in direct view of the spa pool when it is open, he/she shall be located such that the poolside alarm required by Section 9.19. can be easily heard.
“Automated Controller” means a system of at least one chemical probe, a controller, and auxiliary or integrated component that senses the level of one or more water parameters and provides a signal to other equipment to maintain the parameters within a user-established range.
“Backflow” means a hydraulic condition caused by a difference in water pressure that causes an undesirable reversal of the flow as the result of a higher pressure in the system than in its supply.
“Bather” means a person at an aquatic venue who has contact with water either through spray or partial or total immersion. The term bather as defined, also includes staff members, and refers to those users who can be exposed to contaminated water as well as potentially contaminate the water.

“Breakpoint Chlorination” means the conversion of inorganic chloramine compounds to nitrogen gas by reaction with Free Available Chlorine. When chlorine is added to water containing ammonia (from urine, sweat, or the environment, for example), it initially reacts with the ammonia to form monochloramine. If more chlorine is added, monochloramine is converted into dichloramine, which decomposes into nitrogen gas, hydrochloric acid and chlorine. The apparent residual chlorine decreases since it is partially reduced to hydrochloric acid. The point at which the drop occurs is referred to as the “breakpoint”. The amount of free chlorine that must be added to the water to achieve breakpoint chlorination is approximately ten times the amount of combined chlorine in the water. As additional chlorine is added, all inorganic combined chlorine compounds disappear, resulting in a decrease in eye irritation potential and “chlorine odors.”
“Chemical Storage Space” means a space in an aquatic facility used for the storage of pool chemicals such as acids, salt, or corrosive or oxidizing chemicals. “Chemical Storage Space” means a space in an aquatic facility used for the storage of pool chemicals such as acids, salt, or corrosive or oxidizing chemicals.
“Chlorine” means an element that at room temperature and pressure is a heavy greenish yellow gas with a characteristic penetrating and irritating smell; it is extremely toxic. It can be compressed in liquid form and stored in heavy steel tanks. When mixed with water, chlorine gas forms hypochlorous acid, the primary chlorine-based disinfecting agent, hypochlorite ion, and hydrochloric acid. Hypochlorous acid dissociation to hypochlorite ion is highly pH dependent. Chlorine is a general term used in these regulations which refers to hypochlorous acid and hypochlorite ion in aqueous solution derived from chlorine gas or a variety of chlorine-based disinfecting agents.
“Available Chlorine” means the amount of chlorine in the +1 oxidation state, which is the reactive, oxidized form. In contrast, chloride ion (Cl–) is in the -1 oxidation state, which is the inert, reduced state. Available Chlorine is subdivided into Free Available Chlorine and Combined Available Chlorine. Pool chemicals containing Available Chlorine are both oxidizers and disinfectants. Elemental chlorine (Cl2) is defined as containing 100% available chlorine. The concentration of Available Chlorine in water is normally reported as mg/L (PPM) “as Cl2”, that is, the concentration is measured on a Cl2 basis, regardless of the source of the Available Chlorine.
“Free Chlorine Residual” OR “Free Available Chlorine” means the portion of the total available chlorine that is not “combined chlorine” and is present as hypochlorous acid (HOCl) or hypochlorite ion (OCl-).The pH of the water determines the relative amounts of hypochlorous acid and hypochlorite ion. HOCl is a very effective bactericide and is the active bactericide in pool water. OCl-is also a bactericide, but acts more slowly than HOCl. Thus, chlorine is a more effective bactericide at low pH than at high pH. A free chlorine residual must be maintained for adequate disinfection.
“Competitive Diving” means either the training of divers or an actual diving competition among trained divers, which is sanctioned by the Federation International de Natation Amateur (FINA), the National Collegiate Athletic Association (NCAA), the National Federation of State High School Associations (NFSHSA) or United States Diving Inc.

“Cross-Connection” means a connection or arrangement, physical or otherwise, between a potable water supply system and a plumbing fixture, tank, receptor, equipment, or device, through which it may be possible for non-potable, used, unclean, polluted and contaminated water, or other substances to enter into a part of such potable water system under any condition.
“CT Value” means a representation of the concentration of the disinfectant (C) multiplied by time in minutes (T) needed for inactivation of a particular contaminant. The concentration and time are inversely proportional; therefore, the higher the concentration of the disinfectant, the shorter the contact time required for inactivation. The CT value can vary with pH or temperature change so these values must also be supplied to allow comparison between values.

All chemicals in pool water affect the tendency of the water to be corrosive or to deposit a calcium carbonate scale. It is possible to control these two (2) conditions through the use of the Langelier Index (L.I.). The index was developed in 1936 by Professor W.F. Langelier at the University of California (Berkeley). It expresses the relationship between pH, alkalinity, calcium hardness and temperature. The resulting number (formula method - below) or position on the nomograph (nomograph method - Appendix B) indicates whether the pool water is chemically “balanced”. In theory, pool water that is “balanced” will neither corrode nor deposit a scale.
“Balanced” pool water has an L.I. between -0.3 and +0.3. An L.I. that is greater negatively than -0.3 indicates a corrosive water and an L.I. greater than +0.3 indicates a water that will deposit scale. After determining the pool water pH, alkalinity, calcium hardness and temperature, find the alkalinity factor (AF), calcium hardness factor (CHF) and temperature factor (TF) using the table below. Use the pH and these three (3) factors in the following equation:
A pool water has the following characteristics: pH-7.4; alkalinity-50; calcium hardness-50 ppm; temperature-78 F. Using the tables above, the factors are 1.7 for alkalinity, 1.3 for calcium hardness; and 0.6 for temperature. Using the formula:
This pool water is not balanced and is corrosive. The pH is within the required range and almost ideal, however, the alkalinity and calcium hardness should be much higher (see Appendix B). Alkalinity can be raised by adding sodium bicarbonate (baking soda) and lowered by adding muriatic acid or sodium bisulfate (dry acid). Calcium hardness can be raised by adding calcium chloride but can only be lowered by replacing part or all of the pool water with lower calcium hardness water.
Measure the pool water pH, alkalinity and calcium hardness. The pH must be 7.2 - 7.8. pH can be raised by adding sodium carbonate (soda ash) and can be lowered by adding carbon dioxide (CO2), muriatic acid or sodium bisulfate (dry acid). Using the 104 F pH scale for spa pools and the 76 F pH scale for other pools, use a straight edge to line up the pH and alkalinity readings. The point where this extended line intersects the calcium hardness line is the level of calcium hardness needed for the water to be balanced. Do the same for pH and calcium hardness to get the alkalinity level needed for balance. The alkalinity and calcium hardness levels needed should be within the recommended ranges. Alkalinity can be raised by adding sodium bicarbonate (baking soda) and lowered by adding muriatic acid or sodium bisulfate (dry acid). Calcium hardness can be raised by adding calcium chloride but can only be lowered by replacing part or all of the pool water with lower calcium hardness water.
