No. bend of sewer is allowed between flow adopter chamber and manhole No. 2. Show type of manholes. Submit borings for the area. Show type of catch basins . Show type of proposed sewer. 12. Show the deflection angles, radius etc. for all the chambers. 13. Indicate that dll sewers shown as to be abandoned have no house connections.
14. Submit drawing No. C-21 as part of contract drawings. 15. There is no need to show standard details of catch basin type 2, cast iron grating, cast iron manhole frame and cover, cast iron steps, manhole frame and cover, and vitrified clay pipe on cone, cradle on earth or rock as shown on drawing Nos. C-19 and C-20. The hydraulic computations as submitted by you are being reviewed by our Private Drain age Review Section. Their comments will be related to you when received from that office. Please submit three (3) complete sets of contract drawings revised in accordance to these comments for our review. Drawing Nos. S-28, S-29, S-29A, S-30 and S-30A should be made part of the set.
