 and renewed. It is the opinion C
 the engineer that. when the bric
 sections are taken up, the construc
 ton of a new brick pavement on

 Bridges
 The widening and strengtheninl of Black Rock Bridge on West Mail street has been proposed. An esti
 mate of the probable cost of thi work is furnished by the Railroad company is $24.o00. Means of ap
 portioning the cost and providing the city's share of the expense arr now under discussion. The cost O such work being a "change in thu highway" would be apportioned b, the Public Utilities Commission not over one-half of the cost beinf paid by the city. The completion oi this project Is urged.
 Street Cleaning
 A pickup street sweeper has been purchased from the 1927-192S ap- propriation, and is now in operation on the paved and macadam streets So far the operation has been dur ing the day only. cleaning up the heavy accumulation of winter dirt. When this is completed and the pavement repairs completed. the hours will be changed so that the pavements will be cleaned during the early morning. hours when the cars are oft the street. and ma cadam during daylight hours. The pavements are to be flushed and swept alternate nights.
 New Equipment and Housing
 During the past year a paving mixer and a street sweeper has been added to the departments, equip ment making the problem of hous- ing more acute. Provision for an- other building containing repair shops and space for storing small tools ought to be made at the earli- est possible moment, as the present shed was laid out for housing large tools. Now, more than one-half the building must be used for repair shops and small but perishable equipment.
 Sewer System
 Throughout the past year. as formerly. two gangs of laborers have been employed in the construction of lateral sewers. The department had a crane equipped with a drag line bucket which although cumber- some, has done excellent work. Late in the fall the bucket and crane boom were removed and q trench hoe added. This has given better control of digging and more speed. Greater progress is expected with this machine but the board Is continuing it's investigation of trenching machines. having begun to discuss machines nearly year ago. The demand for lateral sew CTS is still urgent in nearly all sec tions, particularly the northerly sections. but no increase has been made in the trunk lines. It is again urged that modern construc- tion machinery be secured. also that an experienced sewer designer study and lay out intercepting sew CTS to take the loads from the pres cnt trunks. This is no criticism of the original design. for many of these sewers were constructed over thirty years ago. Tests to locate im- proper connections to the storm sewer has progressed. and the few found are now being eliminated.
 The storm sewer system is at present much overloaded in many sections while other sections lave no storm sewers. Very severe sudden storms last year effectively demon- strated the lack of capacity of the Lafayette street collector taking water from Broad street. as dirt was carried from the hills north of Broad street to Main street Rail- road crossing. They also showed the need of immediate relief west and north of Pennington avenue. Piper Brook and Cherry street storm Wa ter outfalls should be extended at an early date. Part of the Cherry street brook is being enclosed through Willow Brook Park to the City Line Bridge. Some relief for the Lafayette street line can be se- cured by construction of 60 inch trunk sewer in Winter street.
 Sewage Disposal
 Early last summer. in co-opera- ton with the State Water Commis- sion, work was begun for the pur- pose of gathering information, mak- ing surveys and studies for new disposal plant. A detail survey has been made of the present city prop erty and adjacent property. Meas urements have been made of the flows arriving at the present plant, while the troublesome South Side Trunk sewer has been surveyed with view to increasing it's capacity. Test pits are now being dug covering the area just north of the present beds to determine the subsoil conditions which will likely be the determin- ing factor in selecting the type of plant to be built. The layout now being considered is as follows CD bar screens and grit chambers; CD measuring channel; (S) fine screens: (l some form of settling 'anks, either (a) two story Imhoff tanks, (b) shallow Imhoff tanks with separate sludge digestion, or Co other types of shallow tanks with separate sludge digestion. and (5) sludge drying beds. The liquid affluent from the tanks will require treatment at later date by meth ods to be selected as soon as means for financing can be arranged for. At this point it should be noted that the refuse from the bar screens, grit chamber and fine screens can most readily be disposed of. with
