Section 445A.6672 - Existing systems: Minimum capacities; minimum pressure and velocity of water; total capacity of groundwater system; timely completion of water projects
Current through September 16, 2024
A supplier of water for an existing public water system shall:
1. Ensure that the public water system maintains a sufficient capacity for the development and treatment of water, and a storage capacity of sufficient quantity, to satisfy the requirements of all users of the public water system under the conditions of maximum day demand and peak hour demand.
2. Ensure that the residual pressure in the distribution system is:
Unless otherwise justified by an engineer and approved by the Division or the appropriate district board of health, high head losses must be avoided by maintaining normal water velocities at approximately 8 feet per second during all conditions of flow other than fire flow.
3. If the public water system relies exclusively on water wells as its source of water, ensure that the total capacity of the system is sufficient to meet:
whichever is greater. When computing total capacity for this purpose, credit must be given for any storage capacity.
4. Ensure that water projects are completed in such a manner as to meet the actual maximum day demand, peak hour demand, fire flow and fire demand for developments of property in the area of service of the public water system.
