| 520 | 0 |a"The APHA Research Foundation with the support of 32 public agencies and the Hydraulics Division of the National Water Research Institute have jointly undertaken a study to improve the design of junction manholes. Hydraulic head loss in sanitary and stormwater systems can lead to diminished capacity of the downstream pipes. Such capacity loss may result in raising the hydraulic grade line and the creation of flooding conditions. Relief facilities are often required or new development prohibited in order to protect adjoining property.Thus, minimization of hydraulic head loss in both new and existing systems may be an important tool in alleviation of problems in some key facilities"--Foreword, p. i. |
