To carry out the provisions of Chapter II — "Water Supply" of the Code on Sanitation of the Philippines (P.D. 856), these rules and regulations supplementing the existing rules and regulations approved by the Secretary of Health on 24th November 1995, are hereby formulated for implementation of all concerned.

SECTION 1. SCOPE. — These supplemental implementing rules and regulations shall apply to the following:

1.1 Development of drinking water supply system;

1.2 Establishment and operation of retail water system (RWS) or refilling station;

1.3 Source and product water quality monitoring;

1.4 Drinking water in vending machines and dispensers and product water containers;

1.5 Household and commercial water purification equipment, gadgets and devices; and

1.6 Bulk water handling, storage and transportation.

SECTION 2. DEFINITION OF TERMS. — As used in these supplemental implementing rules and regulations, the following term shall mean:

2.1 AIRGAP — a clear vertical space through the free atmosphere between the opening of any pipe or faucet conveying water or waste to a tank, plumbing fixture receptor, or other device and the flood level rim of the receptacle. An air gap is used to prevent cross-connection between a water treatment device and a possible source of wastewater thereby preventing a reverse flow of water from the sewer into the water supply system.

2.2 APPROVED WATER LABORATORY — a Department of Health-accredited water analysis laboratory.

2.3 APPROVED SOURCE — source of the water whether it be from a spring, artesian well, drilled well, public or private water system, rain water reservoir, or any other source that has undergone a sanitary survey, issued site clearance, constructed, and the water sampled, analyzed, and found safe and potable, issued an operational permit and certificate of potability of drinking water.

2.4 BACKFLOW — flow of water in a pipe or line in a direction opposite to the normal flow; often associated with back siphonage of the flow of used water into a potable water system.

2.5 BACKFLOW PREVENTER — a device or system installed in a water line to stop backflow from a non-potable source.

2.6 BACKPRESSURE — pressure which creates resistance against the flow of water.

2.7 BACK-PRESSURE BACKFLOW — backflow due to an increased pressure above the supply pressure, which may be due to pumps, boilers, gravity or other sources of pressure.

2.8 BACKWATER VALVE — a device installed in a system to prevent reverse flow.

2.9 BULK WATER — water in container of five gallons or more in volume coming from refilling station establishment or water intended for potable uses which is transported via tanker truck or equivalent means from one area to another for the purpose of treatment and/or packaging and human consumption.

2.10 CERTIFICATE OF POTABILITY OF DRINKING WATER — a certification issued by the Secretary or his duly authorized representative certifying the potability and safeness of source drinking water for human consumption based on the Philippine National Standards for Drinking Water.

2.11 CROSS-CONNECTION — any connection or arrangement, physical or otherwise, between a potable water supply system and any plumbing fixture or any tank, receptacle, equipment or device, through which it may be possible for non-potable, used, unclean, polluted and contaminated water, or other substances, to enter into any part of such potable water system under any condition.

2.12 DEIONIZATION — the removal of the ionized minerals and salts (both organic and inorganic) from a solution by a two-phase ion-exchange procedure. First, positively charge ions are removed by a cation exchange resin in exchange for a chemically equivalent amount of hydrogen ions. Second, negatively charged ions are removed by an anion exchange resin for a chemically equivalent amount of hydroxide ion. The hydrogen and hydroxide ions introduced in this process unite to form water molecules. The term is often used interchangeably with demineralization.

2.13 DISTILLATION — the process of separating organic and inorganic solids from water by evaporation (vaporization) followed by cooling and condensation.

2.14 ESTABLISHMENT — a collective term construed to include buildings and premises where retail water system product water or refilling station product water is being processed.

2.15 FILTER — device installed as part of a water treatment system through which water flows for the purpose of removing turbidity, unpleasant taste, odor, iron or color. Filters can be loose media beds, in tanks or cartridge-type devices. Filter media may be used for mechanical, absorptive, neutralizing, or catalyst/oxidation filtration process.

2.16 FILTRATION — the process of separating solids from a liquid by means of a porous substance such as a permeable fabric or membrane or layer of inert media.

2.17 GOOD MANUFACTURING PRACTICE (GMP) — the detail requirements governing plant construction and design, sanitary facilities and operations, equipment design and construction, production and process controls specific to the production and purification of water.

2.18 HORIZONTAL PIPE — any pipe or fitting which is installed in a horizontal position or which makes an angle of less than forty-five (45) degrees with the horizontal.

2.19 HYDROSTATIC PRESSURE — a measurement of structural strength and ability to hold water pressure.

2.20 ION EXCHANGE — the reversible process in which ions are released from an insoluble permanent material in exchange for other ions in a surrounding solution; the direction of the exchange depends upon the affinities of the ion exchanger for the ions present and the concentration of the ions in the solution.

2.21 POINT-OF-ENTRY (POE) — a water treatment device that is installed at the main inlet to a building or mobile vehicle and acts as centralized water treatment.

2.22 POINT-OF-USE (POU) — a water treatment system designed to connect at the actual point-of-use for water; countertop or undersink treatment system.

2.23 PRESSURE — the normal force exerted by a homogenous liquid or gas, per unit of area, on the wall of the container.

2.23.1	STATIC PRESSURE — the pressure existing without any flow.
2.23.2	RESIDUAL PRESSURE — the pressure available at the fixture or water outlet after allowance is made for pressure drop due to friction loss, head, meter and other losses in the system during maximum demand periods.

2.24 PRESSURE BALANCING VALVE — a mixing valve that senses incoming hot and cold water pressures and compensates for fluctuations in either, to stabilize outlet temperature.

2.28 REFILLED WATER DISPENSER — an equipment used for dispensing processed drinking water either as a coin-operated machine, a monetary-driven equipment or manually operated machine.

2.29 REGULATING EQUIPMENT — includes all valves and controls used in a plumbing system, which are required to be accessible or readily accessible.

2.30 RESIDUAL — the amount of a specific material remaining in water following a water treatment process. It may refer to material remaining as the result of incomplete removal such as hardness leakage, or to a substance meant to remain in the treated water such as residual chlorine.

2.31 RETAIL WATER SYSTEM (RWS) — refilled water being sold and placed in the refilled water container or in customer's containers in refilling station.

2.32 REVERSE OSMOSIS OR HYPERFILTRATION — a process for the removal of dissolved ions from water, in which pressure is used to force the water through a semi-permeable membrane, which will transmit the water but reject most of the other suspended and dissolved materials. It is called reverse osmosis because mechanical pressure is used to force the water flow in the direction that is the reverse of natural osmosis, namely from the dilute to the concentrated solution.

2.33 SANITARY CLEARANCE — a clearance issued by the local health office to food or water delivery vehicles, mobile water tankers and similar vehicles, including its appurtenances that they comply with the design, construction, specification and other requirements of the Department.
